is BUDGET induction cooking ACTUALLY POSSIBLE? Pushing my 12v Camping setup to its limits.

[@AussieArvos]

Essentially this issue comes down to the voltage of the battery getting too low when we are drawing the high current from it. As a lithium battery has a BMS (battery Management System) that is designed to keep all the cells happy and healthy as soon as the voltage drops below 11.3 power is cut. you would almost have a better shot using AGM or Lead Acid or Gel for this battery size as they do not have BMS and allow you to draw as much as the battery can handle! (this is not healthy for the lifespan of the battery and of course those batteries have many disadvantages compared to lithium). And as i mention this could also come down to the quality of the cells in the kings battery, or even the quality of the BMS but i think if you are buying lithium with the intention to cook using electricity i would be buying no less the 200Ah.

[@thegolfhack9417]

You shouldn't get a huge voltage drop with lifepo4 even with a .5c discharge 60amp should be fine id assume the bms is limited to about that with this quality of battery anyway id be measuring voltage directly at the battery and also at the inverter to see if your voltage drop isn't coming from there but thinking now its the bms cutting of not the inverter reaching a low voltage disconnect id say the bms wire size cant handle 60amps and thats where the voltage drop is coming from or a faulty cell the wire size on all bms's is usually undersized

[@brentmcd12]

im still in the ads but I thought the lithium had a built in voltage regulator also. even if high current draw ?

[@thegolfhack9417]

@@brentmcd12 no they have a bms battery management system to protect individual cells most bms's now have balancers too to keep cells in balance but if you look at a discharge curve even with a high discharge its a very stable curve untill you reach ethier end of the scale thats why its basically impossible to use voltage as a state of charge at 15%-90% voltages are near identical

[@hughbart]

May have already thought of it but is the gauge of cable enough for 50A plus? May find a bit of resistance is causing the drop. Is there some kind of voltage regulator that could fix this? I appreciated this video 👍

[@paulholyoak]

Pat this is what i think your issue is here. Your Kings 120ah lithium battery is only rated at 100A continuous discharge. 100A x 12v = 1200W. So if you have the cooktop running at 1200W that already maxes out the battery's discharge rate. There is simply nothing left for anything else (including the inverter itself). The simple fix for this is to add another 120ah battery and run them in parallel so that you essentially have 2400W of continous discharge. You also get the added bonus of the extra 120ah capacity.

[@colinsmith6340]

Hi mate, i work at a battery manufacturer in Brisbane, and i can tell you something is up with either the wiring or the battery or the charger. A full lithium sits at about 13.8 volts, 13.1 is very low, just run over your charging system. The BMS cuts are usually because one of the cell banks has dropped too low, so yea, really check over your charging setup.

[@aaron.courtney]

Agreed, I would have a guess there is some sub-par wiring either between the charging system and the battery, or the battery and the inverter. The voltage seems quite low. Running the travel buddy at the same time is probably a big ask, but there is no good reason to why that 120ah (100A continuous, 160A peak) battery and the 1,500w inverter can't power that induction cooktop on the 800w setting (they use 850w at the wall on that setting)

[@lexicase8805]

Probably a good chance the wire included with the kings inverter is too small, and not sure if the inverter is running through one of those lever type breakers, but if so the voltage drop across that would be a huge contributor. Between the safety in the bms, and the internal fuses inside the inverter, a direct connection between battery and inverter with short cables and no breakers should be ok. If you do run a fuse, it should be a 200-250a class T. A good investment when doing elaborate setups like this is a thermal camera, even a really cheap one, will help find faults or high resistance connections very quickly. Guarantee those lever type breakers will be lighting up like a Christmas tree. Also worth noting the kmart induction cooker on the temperature control setting pulses power, as do the wattage settings below 800w. The 1000w setting draws around 1050w from the inverter, and with conversion losses that equates to around 130a from the battery.

[@colinsmith6340]

@@lexicase8805 If that was the case, the amp meter would also indicate 130 amps from the battery. It just seems like the internal wiring, the internal resistance, or the bms of the kings battery just isn't up to scratch. I make batteries for a living, and i was pulling 160 amps out of a 100ah battery yesterday and getting 12.8 volts.

[@lexicase8805]

@@colinsmith6340 i think you're absolutely correct, i commented while watching the video and made an assumption, but yes for the bms to be cutting off like that it has to be internal. Looks like the free battery that was given to cover damage caused by a faulty product is now also faulty! Not looking good for kings 😅

[@adamtolley5739]

Go buy a cast iron pan with a full cast iron handle wrap the cast iron pan in alfoil and mount it near or on your exhaust manifold while your driving then it's hot for when you want to start cooking remove the alfoil and it should be clean and ready to go

[@Aussie_Damo]

Sounds like the kings 120A lithium battery is 50A max continuous Amp draw and not 100A like on the website. With your travel buddy at 4A and fridge at 2-3A when you go to 800w with the induction cook top to sits at the 45-48A mark, any higher it trips the BMS of the lithium battery. The only way to fix it is to buy a proper lithium battery brand with real world tested specs or get another battery and run it in parallel so you have twice the amp draw capability. Dude keep up this content it is awesome.

[@krump743]

The travel buddy draws more than 4 amps or what ever he stated in the video. He had it pre heat for 45 minutes, cooking for 45, and extra cooking for 45, thats like 2+hours. Thats least 20 amps (10 amps an hour) and old mate said it only used 4 amp hours of battery. His battery monitor is wrong.

[@Paul-mt7dq]

Interesting video, some great ideas here. I would have to disagree about the cause of your problem. I have a 200AH lithium setup myself and was looking for a coffee maker to plug in to my inverter. The small Nespresso machines are 1300 watts so my 1,000 watt inverter won't do that. The problem with going to a 1500w inverter is that my Lithium battery is rated at 100amp maximum draw, as is the Kings 120AH lithium you are running. This means that you can get a theoretical maximum of 1200w (W=VxA). When running through an inverter you will get losses due to the cabling and the inverter itself so it will realistically be closer to 1100w. This, I believe, is the cause of your power cutting out. Your battery can hold a 160A draw for 10sec but it will not provide more than 100A for sustained periods. Amps draw and Amp hours are two different issues. The solution, if you have the space and the bucks, is to run two batteries in parallel thus doubling the available current. Lithium batteries are available with higher current ratings but obviously cost more.

[@mathewsimonelli1332]

. doubling the battery won't allow 200a draw as each battery has an independent bms only allowing 100a constant draw. although it might stop the voltage drop his getting at 60a draw. I would have thought the lithium wouldn't see that much voltage drop under that load. maybe the difference between high end cells and cheap cells.

[@kennybirdbrain922]

Great video, mate. I've been running inverter cooking on a budget system for a couple of years now. Hell, I even started with a Kings 100AH AGM and the inverter/induction cooking. Killed the AGM after some time, but it worked well. The great thing about going electric is the maths. If you work out what you need with the math it will work. I don't know what your system consists of behind the battery to the inverter but if I was to take a guess, there is a large loss occurring between the battery and the inverter. Cabling size is crucial plus the distance of cabling has an effect on resistance. Resistance means heat, heat means loss. Your volt drop is because the inverter wants the amps/watts, it will try and take what it needs in amps/watts from the battery to service the inverter demand but because there is resistance, something has to give and that's volts. As the heat increases the resistance increases which makes the problem exponentially worse over time. I now have a quality 200AH lithium but evolved from the 100AH AGM to a 100AH budget lithium. The cabling is AWG 0000 (12mm dia) with the longest length of about 500mm. Pulling 120amp continuous, the cables are just slightly above ambient temp to touch. Enerdrive have a very helpful cabling table on their website to help with cable selection.

[@dannystrachan475]

The induction cooker does not run continuously at the set wattage. The set wattage is to indicate how much power will be used in a hour. The induction stove pulses, using max power. The slower the pulsing the less power is used in 1 hour. The higher the setting the faster the pulsing and the more strain on the inverter and battery. The inverter needs to be oversized as well as the battery.

[@MiniLuv-1984]

Your setup is excellent and it will work fine with the inductive cook top, but a few small details you need to take care of that are letting you down. First, check the voltage at the battery terminals with a multimeter. Turn on the load and see if it actually drops to 11V. If it does, the BMS is faulty or badly wired to the terminals. Kings need to replace the battery. If that checks out ok, the voltage drop will be occurring between the battery terminals and the inverter. Check connections and upgrade them, check fuses and any kills switches from the battery to the inverter by measuring the voltage drop across each components terminals and finally check each cable, positive and negative from the battery terminal to the inverter. The cables that Kings provides are way under size for 2kW as you need to allow for something like 200A when the battery capacity depletes and its voltage goes down to 11V when the maximum current will be drawn from the battery by the Inverter. I suggest you run 95mm2 cable (for 3m return battery to inverter and back).

[@jerrymyahzcat]

Nicely said. I run 95m㎡ cables directly from my 300Ah Lithium (200A max continuous) to my 3kW Inverter. It happily powers my 2400W Ninja Foodi Flip Air Fryer or my 2200W Induction Cooktop. [Obviously being limited to 200A continuous I can’t run the inverter at max. I chose to buy one 300Ah battery instead of say a pair of 175Ah/200Ah or whatever].

[@Verb130]

I run two induction cook plates with cast-iron and steel fry pans with a 300w solar panel that usually outputs about 200-230 watts into my 2000w battery generator. I never loose power cooking. I also have USB tent lights and heated blankets.

[@richardatkin8526]

Love that you're testing budget friendly options! Here's my two cents... 100-120ah lithium battery is sweet for a typical set-up (fridge/ lights/ charging devices), could probably add travel buddy at a stretch, but you need to double the battery capacity (and solar in) to go 100% induction cooking. The whole point camping is to not have to worry or be stressed so I'll stick with gas/ fire cooking for now I reckon. Will keep the battery healthy for longer too, lithium is getting cheaper but not so cheap that I can afford to burn through them unnecessarily... PS. you can always add a basic windbreak to make your butane cooker more efficient, or cook downwind from your vehicle

[@Skurfer000]

Don't know if anyone else has mentioned it but you should get a cheap air fryer and give that a spin. I'm thinking of getting one for the ute as we use one at home all the time and it is great. I think the smaller 3.5L ones run about 1500w

This old man enjoys watching yours and your cohorts videos - y'all really got it going on. It's great that you try this while home or local so you have familiarity with the process if needed when off remote. We run drills twice a year to see how fast we can load-out and then check inventory and re-stock anything needed. IMHO, electric cooking when remote isn't a good idea (should be reserved for emergencies due to being a power hog) - we keep at least 2 beefed-up heavy-duty home-made Copenhagen Solar Cookers behind the seats to use when there are no fire conditions. We also love our Stove-Tec Rocket Stoves and our Deadwood Rocket Stove when at the farm and remote.

Good one to test your system.👍 There's no greater peace of mind knowing what you're taking on a trip works its intended design. FYI... I don't preheat when cooking with a Travel Buddy. It just seems like a waste of power. I just chuck in the food and turn it on. I simply add about 20%-30% cooking time. And it works each time. I too am looking into induction cooking. but would need to upgrade my 1500W inverter to a 2000W version, for greater flexibility and peace of mind. Might look into a voltage step-up converter. Thanks for sharing. 👌

Thanks for doing this, it's great to see what happens when you have a 100AH lithium battery set-up (which is normal) as opposed to some other youtubers who have 200-400AH set-ups and go on about how good it works. It confirms that I should just stick to my gas set-up (for now) and use the battery for basic appliances like my toaster and when I eventually get a second lithium battery, then think about using induction.

[@Beng177]

That kings battery has a maximum sustained discharge of 100 amps. At around 12 volts it works out to be roughly 1200 watts. At those discharge rates the internal resistance in the battery will begin to show and will begin to drop the pack voltage + heat the battery cells causing everything to be inefficient. What you need is another battery in parallel (double the capacity + larger discharge) OR a bigger lithium battery rated to a higher constant discharge.

[@jarred3424]

Exactly

[@PeterPaoliello]

This is my exact problem, and I'm finding a lot of variable induction cooktops cycle on and off at full tilt, rather than using less power on a consists basis

[@BK-ku3mf]

It is the battery output that is the limiting factor not the inverter. The Kings battery is only able to output 100 amps. If you had a itech for example they output 150 amps which would run your inverter properly at 1500watts. Because the Kings won't do the amps you get a hit on the volts. Hope this helps. Your options would be parallel 2 x batties, I think the Kings bms should allow this BUT check or upgrade to a battery with more amperage output and a better BMS

Someone has probably already commented this but I think you are in lower state of charge than you think. Doesnt the battery have bluetooth app? Bluetooth BMS or a really good ah-counter ( like victron bmv-712, not cheap..). Thats the only thing that can give you correct state of charge. Voltage is not applicable with lithium. At least charge the battery fully with lithium charger ( like you have been driving all day. I use microwave oven and kettle. Some frying with induction ( breakfast pancakes, bacon n eggs). And i use mainly my still going 190A agm ( cheap start-stop battery). But its charged fully almost every day since 2018 since its my workcar too.

Ensure max output of the BMS is greater than 100A induction cooker should be able to boil and sear on about 1000w so not much need to go higher than that. (Breville -$50 goodguys) Inverter will need large cables and to be mounted as close as possible to battery to minimise volt drop.

What induction cooker are you using? Assuming its about 1200w max?

[@gokalpaliriza2527]

120amp lithium batteries usually have a discharge rating of 100 amps which is approximately 1200w. Induction cookers draw between 1000w to 2000w depending on its heat setting. You are running additional fridge + lights hence why the BMS is shutting off the battery. AGM batteries do not have a BMS integrated, thus they can run inverters more effectively. If you want to run a fully functional lithium battery you must invest in a 200 AMP which generally has between 150/200 amp discharge rating, which means you can easily crank to about 1800w/2400w.

If that Hot Plate is really 1200W then it will draw 100A at 12V (92.3A at 13V). So the 66A draw on setting 4 means it’s only drawing about 800W. Also you need grunty cables to pull 100A+ (which your battery can’t even provide). Your inverter at 12V and 1500W would be 125A, the battery is rated to 100A max continuous. Travel Buddy won’t draw 3A. They are 130W so at 12V that’s 10.8A. My KickAss one draws about 11A (13A with the light on). Best to turn off the fridge and Travel Buddy when using the Inverter at high loads. The step-up voltage converter for the Travel Buddy will shorten it’s lifespan as it’s not designed to run on higher voltages - also it will almost certainly void any warranty you may have. Keep that in mind. That was 850mAh (not mA) just to preheat the machine mind you. Not to make the coffee. I use a pod machine when camping as it’s so much easier to use with none of the cleaning and fluffing about with coffee grounds. Your Ah capacity is fine at 120Ah. Not fine for very much cooking though as 120Ah will vanish fast. It’s just the battery (or inverter) can’t sustain the power draw. You also should run the inverter directly off the battery and not through any intermediary things except maybe a switch, fuse and a shunt if you NEED to measure it’s usage. I run my inverter directly off my battery which never shuts off - but if I draw too much power for the inverter - the inverter will trip. But my lights and fridge will keep going as they are not affected by the inverter tripping. I’ve never had the BMS shut off power except when the battery got to 0% SoC. When using gas to cook its best to use a shield to keep the wind away as gas will take much much longer to heat when it’s windy - sometimes it will never heat if too windy. Also be mindful of terms Amps and AmpHours. At the end you said the system was using 42Ah when I think you mean Amps.

Pat not sure if you read any of my comments eg hoist adjustment, some induction cook tops work on lower settings by pulsing full power, so your induction cook top maybe pulsing 2000 w for 50% of the time so they tell you it’s 1000w. Not all do this so if you have a marginal battery in terms of bms it may not cope. High end induction cooktops apparently don’t “pulse”

[@robparsons5430]

Put a clamp meter on your 240 volt and see if it pulses

[@technicallysquirrel]

Amp hours is the measure of battery capacity. Amps is the actual current and watts (current x voltage) is the power. Regardless of the amp hours capacity of the battery, it will have a max current and power draw rating. The reason your power cuts out is because the current draw is higher than the battery can sustain. Rig up more batteries in parallel to increase the max current draw and you’ll be golden.

[@TheRealBobSmith.]

That view is very nice. I like induction cooking .

[@lukehutchinson6754]

I'd be really keen to see if you swapped for a different 120Ah lithium of a different brand whether you would have the same cut out. Great episode and it is making me think how large a system I will need to build. I want portability so it won't be a permanent installation more solar generator size. Cheers 🍻

[@Jack-is8xz]

I have an allspark lithium 100amp battery. And I have pulled over 100amp successfully using an enerdrive inverter without any severe voltage drop. Might be the cable size contributing to the voltage drop or just the kings equipment/battery not up to the task

Wouldn't be a bad idea to make up a wind break for the butane cooker. Can be made out of cardboard but for durability can make it out of 2mm steel and some piano hinge. Inexpensive and effective.

[@leopoldnine]

Hey, Patrick. Time for an update? I'm keen to see how the system is running long term.

[@pingpong9656]

All I want to know is if you can run induction cooker of the main car battery and alternator - so you can use it occasionally with engine on..

[@sailinghalcyondaze6848]

Heya, I've bought an "Aussie Battery" brand lithium 330 amp/hr triple BMS. The amp draw is insane, from memory around 250 amps set up in 12 v system. Only paid $1800. Couldn't be happier with it. May be an option having a chat with these guys, doing an honest review for a free battery!! Never know, enjoy ya vids😁

[@starshipdriver8536]

Get cybertruck, plug in the induction cooktop to the outlet in the bed and it's that easy.

[@Bush-Tv]

Another great one mate. Looking forward to the Big trip.

[@jasonsampson916]

Hey the dubble butane one from Kmart! It’s the best, yes it dubble the size but it’s dubble the cooker and has a full size hot plate bbq that can cook a 24 pack of snags all it once

[@logankerr9178]

The issue isn't the AH/capacity of the battery it comes down to the quality of the cells within the battery and the bms. The bms will be rated to a particular amperage for continuous discharge I suspect it is 50 A for this battery. A higher end battery and bms pairing would typically allow for 100A continuous discharge without the voltage drop you are dealing with.

[@Topey35]

Hmmm... Is that battery really able to discharge at 100amp as advertised?

[@davidprice7823]

What's your max amp draw on your Battery ? 50amp it will cut out, I have a max 200amp draw on my battery and works well, I use induction all the time and 13 volt oven no problem, but my inverter also 1500 will cut on any big pulling items, you need a bigger amp draw on your battery then it will be good 👍

[@adamreichart7343]

thought i let ya know. your running the induction at 1200watt which is 100amps. battery is only rated at a discharge of 100 amps and 125 i think for a peak. keep that in mind. your inverter is rated alot higher than your battery output.

[@DENMONKEY]

mate , try an air fryer. I have a 300Ah lithium and when running a 2000W inverter, tried an induction cooker first. you can lower them down to about 1000W to work with your inverter. An air fryer is the way to go though for sure. granted i went to a 3000W inverter but they don't run the whole time. the duty cycle is like 25% so very efficient.

[@Mambey]

The old cook tops take ages to heat up. You need a good/flat frypan for better contact with the hot plate. You got it at breakfast.

[@lienchase2301]

I had similar experiences running on Jura super automatic coffee machine. The power consumption is 1450W but Kings 1500W inverter beeps like yours although my AGM battery were charged and displayed at least 12V.

[@returningtoearthtv8836]

Im curious about that wiring job you did - splicing the new USB plug into the LED strip. Does the existing wiring and fusing work with the extra load of the USB ports? Also, what connectors did you use? Looked like mebbe electrical tape? I assume so. Just thought I’d ask. P.S. yer vids are awesome. I really appreciate and am able to learn from your speaking/teaching style. Works for me. Very approachable and inviting. Thanks for that. Keep it coming.

[@offugo-adventures]

Should also get on Somerville metal works and get the insulated and latched door. Helps a heap with heat loss through the travel buddy

[@AdrianLeviAU]

Inverter wattage ratings are based on what the inverter draws from the battery, not what it supplies on the 230v side. Most inverters are 80-95% efficient depending on quality. Your 2000w inverter is providing around 1600w.

[@unintentionallyoffgrid]

Firstly, your food looks absolutely awesome and so very tasty! (except the wedges, didn't have me 100% convinced with those, especially with how long they took haha! I'm sure they were awesome though!) I currently run everything through a 1300 watt 100 ah portable power station. All 240v (but my lights and a few other things are USB chargable). I initially looked at those portable ovens like you have, but ended up instead with a $79 oven (it's about the size of a microwave sort of) which I can cook pretty much anything in, no preheating required either. Takes pretty much the time of a "normal" oven to cook things too. Uses 1200 watts. I also got some cheap appliances from Kmart (microwave $52 uses about 1200 ish watts) and the best buy ever, their $22 sandwich press (1000 watts) which I can cook anything from toasted sandwiches, to steak etc. You might even be able to cook your wedges in there! To give you an idea, to cook a toasted sandwich, it uses less than 10% of my total amp hours. I got an induction cooktop from eBay which is good also for cooking - put a lid on top, will cook faster ;) I can do roast veggies also in the oven, which generally takes an hour, that uses 40% of my 100 amp hours. I've also made cake, boiled water etc in this tiny little 300 watt nostalgia brand pan (Kmart have them too, different name though they look the same - 15 bucks I think?). It's all 100% possible. I use no gas, no diesel - just the power of the sun. I haven't done a setup with the separate components like you have here, but am looking into doing that when I can in the instance I want to run a heater or aircon ever (currently have neither). Happy travels, and thanks for the videos :)

[@Inserico]

Great video mate! Love the way you present/talk to us through your videos, very approachable! I'm most interested in the part where you talked about the coffee machine. I saw the power spec from that coffee machine's manual, and it says 1.4-1.6kW. I was wondering how did you get 60A draw from your battery at that power range? Or am I missing something?

[@johnmathisen1167]

A brilliant review mate and also keep an eye on your missus as she might have a go at taking over, keep at it kids.

[@Handleyman]

I have the exact same induction stove and it keeps on tripping just like yours. It’s good to know what’s causing the problem. BTW I have 2 x 120 lithium batteries and it does the same thing!!

[@TheSimpleLivingAussie]

A bit late with my comment but for what it's worth. I have lived with off grid power for over 20 years and Lithium batteries are a game changer. Since I went over to Lithium, I have been able to run soooo much more from my system.

[@ricki11cook]

I'm thinking its the battery quality letting you down, or you have voltage loss through your wiring. My previous setup had a single 100Ah DCS Lithium & 3000w Redarc inverter, I could hammer it with no dramas at all.... ever. I've since moved that setup into my camper trailer (Kings btw, so can't label me a brand snob haha) with 4x VoltX 100Ah batteries so there's always enough headroom to support the inverter with a larger load, like a toaster & coffee machine running at the same time. Travel Buddy's certainly need the buck-boost converter. Running them on 14.5-15v makes them perform way better. Always enjoy your content, keep it up.

[@shadowrg1]

i've done some research for a 12v system, using electric cooking is min 2 to 3 batteries, so my system i will be making is going to have 3 lithium batteries at 100ah just to handle the spike draw of the appliances i will be using, and constant draw for the few minutes they will be on.

[@overlandmk4]

Took me 6 minutes to realize that you were wearing a dayz shirt, my favourite pc game!

[@johnallen3555]

I would recomend a battery capable of 200A continuous draw for cooking - The issue you will face is depleting the battery with the high draw cooking and not having sufficient solar to recharge it when you are camped up - your Kings battery is spec as 100A, yet has issues delivering this (perhaps some further testing here and then talking with Kings.) My understanding is that the battery should not go under voltage whilst delivering 100A continuous untill virtually flat.

[@scotthepburn6616]

I love your videos, always informative and yeah I’ve got an old school dual battery set up in my 100 series but I will be upgrading to two slim line lithium batteries in the future so I can can run induction as it just seems to be the way to go.

[@jarredcox1738]

Not to do with your inverter setup. But for the rooftop tent I run a 20Ah power bank sits in one of the pockets, charges my phone 4 times and can run the led strip light. Food for thought, I just didn’t wanna run cables in and around it

[@sashneda7104]

Hi mate not the battery as it may only be a constant 50amp max draw only, you may need to get a higher constant amp lithium battery, mines a 100amp max constant battery and 100ah.

[@stephenm8894]

Try running power for the RTT up the snorkel. Way better than a grommet through the roof. Just asking for trouble with that.

[@fo3]

Good to see. I've been following your adventures and thought of similar things (just was deciding on battery and inverter). I have the old kmart butane stove and also got the kmart fry pans which I see you finally got - they work great on the campmaster. I'm a bit iffy on inverters and induction but I have bought a small breville espresso maker which I hoped to use eventually (was a fan of their dual boiler BES900) but bought a non boiler thermojet/instantaneous espresso machine similar to how all the smaller machines are. For cooking backup as well as the kmart campmaster butane I also bought a Dometic Lpg baby grill as back up - CBP101. E: Also looking into an evakool DC40 drawer fridge/freezer to mainly use as a freezer. Because of your video I'm now looking into the travel buddy pie warmer too! I guess I'll need more battery capacity after watching this.

[@hereholdmybeer5273]

check what the continuous amp discharge rate is on the battery. most cheap batteries will only have a 50amp continuous discharge rate. could be contributing to the battery kicking out

[@robertrichmond1423]

Reckon that the limiting factor is the output current of your lithium battery, not the capacity. 120Ah is enough. But if it can only provide it at a low rate for example 50amps per hour, and your cooktop is drawing 80 amps per hour (just an example) then your battery voltage will drop and bms in your battery will cut the connection. That is why your coffee machine works fine (lower current) but the induction cooktop doesn’t unless it is at a lower setting.

[@DiscoStu30]

either run an 2nd battery in parallel to increase the max cont amp, or upgrade the batter and be sure to look at that spec.

[@sparrowmict]

I am guessing it’s the discharge capacity of the battery. My lithium iron phosphate battery and bms is rated at 150 amp/h discharge rates. I have 150amp/h capacity battery diy from individual cells and a bms and it’s charged from a 50amp renogy DC/DC charger. It runs a fridge 24\7 without any issues and it’s even sat without the truck running for over a week without any issues. I have an induction cooker I want to incorporate into my setup, just need to get a 2k watt inverter. I have a 100 watt solar panel to go up on the rack but ended up in the hospital with a triple heart bypass so that’s gonna have to wait for a few months.

@@AussieArvos what gauge wire is the inverter using the voltage drop isnt coming from there

[@cgrecommended]

According to the specs on the king's website, they are grade A cells and the battery is rated to 100A cont, 160A pulse, that's some pretty bad sag if 1200w tripped it (as volts drop, amps increase to keep up the draw wattage). I'd be measuring voltage at the inverter input posts vs the battery posts to see if you're getting any significant resistance/voltage drop somewhere, or if Kings misrepresented their draw specs.

[@thegolfhack9417]

@@cgrecommended i was thinking the same thing but its the bms tripping not the inverter hitting low voltage disconnect so the bms must be reaching the low voltage disconnect im now thinking the bms wire size isn't able to carry the current without the voltage drop?
