[@WhatNowChris]

I purchased a 12v 200AH AmperTime battery last year with my solar kit just for power outages. It’s never failed me. This year I added another 12v 200AH LiTime to increase my local storage. both are incredible batteries. For power backup, I highly recommend. I’ve had lights, refrigerators and tv running during hours long outages. My neighbors are in the dark and I was the only one with power on the block. I’ve noticed more solar panels going up on rooftops in my neighborhood this year! I think I’ve set a trend around here! Eventually I will go full solar to power my entire house, within the next year or two. Great Video!

[@SMM-Mystery]

Hey Will, most boats (especially sailboats) are a 12V system. You will find 24V setups, but rarely a 48V system on boats. Unless, of course, they're a Mega Yacht. For the larger voltage systems, the wiring requirements become a constraint. I would love to see you do a series on boat utilization of lithium batteries.

[@markmonroe7330]

Excellent presentation. Thank you. I have had the Li Time mini version in my truck camping setup for a few months now. The size and weight are great for me. I have a fairly small truck camping setup but really like having 12v. I can directly use 12v truck camping stuff directly from the battery. I can also directly charge my Bluetti EB70 directly via the 12v feed with no power sucking boost converter needed. I can also jump start/charge my truck directly from the mini. I can fully appreciate the higher voltage batteries - 24v - 48v - but in a simple camping/truck/van setup, it is hard to beat 12v for all round flexibility.

[@CLyon-cc9jp]

Question for you. I am new to Lithium Ion Phosphate batteries. Can I charge one of these with the built in 12 volt charger in my camper? I am finding it difficult to find the answer for that.

[@jjvegas2727]

Thanks Will, I used your book in 2017 for my first solar install (12 volt for my 5th wheel). I just purchased 2 of these LiTime 460ah with LiTime 60 amp MPPT because the lead acid are starting to fail. I am retaining some exist lead acid because these lithium batteries are not to be used for starting a generator. HEADS UP to your group, the LiTime materials states two variations regarding ADDING additional batteries into your bank. One states: additional batteries must be purchased within 3 months of original purchase date to maintain battery warranty......other location states within ONE MONTH from original battery purchase date. Maybe you could address this topic for folks whom wish to expand their existing lithium banks or wish to mix different battery MFG's. So, if someone wants to add more amp hour capacity after the fact; It appears, I will have to sell the existing bank batteries and start new , OR add an additional controller with a new battery bank but this creates a further questions/risks of merging both via a battery selector switch 1 or 2 or both battery banks. Please opine and a huge thank you for all your years of education on solar.

[@MarkSmith-Uzor]

[@macdaddykwm1]

It's not just the cost of the low-temperature sensor, it's the liability if the battery is damaged due to freezing.

[@ericklein5097]

Which doesn’t matter because they aren’t going to warranty a battery that’s a year old and shows serious degradation. They’re going to look at your shipping address and likely blame it on the weather

[@lenwhatever4187]

"12v volts just costs more".... yes for the user, but for the manufacture maybe the BMS is enough cheaper and the assembly is enough cheaper so that 12v is cheaper to produce. The other thing is that 12v appliances are still the ting that most people have access to and draw no quiescent current the way an inverter does. For off grid use where solar panel area is restricted such as RV or boat.... 24/48v is possible but not common, easy or cheap. A lot of times, the draw is quite low and legacy wiring for things like lights are already over sized as the lights get changed to LED lighting. The biggest draw tends to be the fridge at 4 or 5 amps. Fridges seem to built for 12or 24v not 48 and running multiple voltages is not a good idea. So yes, 48v for an inverter based system is the thing. For DC use, 12v is still more common. This is starting to change as more manufactures are building 5v only stuff, like lights and fans. The 5v fans are pretty much useless but 12 v fans are hard to find even in automotive stores. 24or 48V starters and winches are available but costly, not because they are harder to build but because they are not common. A push for higher voltages is still for the rich or commercial (trucks and other machinery have had 24v for years).

[@fauxque5057]

Being in Florida I don't care about the low temp sensor. My batteries are on the back patio and during the relatively few days where we hit freezing I have a small insulated 3 wall enclosure that I push up against the wall. The heat from the LV6548 is enough to keep the temp inside 30°F above the outside temperature. I've also found adding a 60w incandescent light bulb in the enclosure brings the temperature up another 20° So far I haven't frozen my batteries. 😊

[@pboxelement]

Thank you for the review from an RV- ER

[@ExodusC]

Hey Will, small correction- just because they label them as "Plus" doesn't mean they don't have low-temp protection. I have the 230Ah version that they bill on their website as having low-temp charging protection, but the battery itself doesn't have any branding to indicate that- just the "Plus" branding. I agree 100% though, it also doesn't have any indication on the battery as to the BMS maximum amperage. They need to put this stuff on the batteries!

[@WillProwse]

Yes the plus doesn't mean that. and right?! They need to add it to the front of the battery

[@oneeverest7332]

How is that 230ah battery? I’m thinking of getting one for my class c RV to replace the two batteries in the step battery compartment.

[@erickw760]

I've one in my minivan running an induction stove, Keurig, fridge, diesel heater, 40 amp DC box, and more and have been very pleased with it. 234Ah has been my deepest discharge till LVD. 2.5Kw output sustained no problem and I believe it was a 400 amp surge for 5 seconds.

[@crw-bm7mm]

Looking at that one for my rv. Will it fit in an 8" wide box?

[@AdministrativeReload]

I have a couple of the minis that I use interchangeably for a 24v inverter I use for power tools around the farm, and a lightweight portable 12V system when I am camping. But it can get frosty in the morning when I am camping in the desert in winter, so that means I have to have to rely on my charge controller's low temp protection which makes me a bit nervous. I do really like how small and light they are though. I also have a couple of the standard size ones that I am using with a 24v split phase inverter for my off-grid shop. Works great for welding, running saws, or just keeping the lights on. I probably should have gone with a 48v server rack system in the shop, but the 24v setup with the litime batteries had a lower price entry point and I was on a budget.

[@josephcormier5974]

Thank you sir I still use 12 volt system this is a comfort thing excellent video thank you for sharing this six stars

[@Electronzap]

Nice review. If I had the budget for batteries, I'd definitely get a couple 100Ah li time minis right now.

[@WillProwse]

Right, not bad

[@CFPVideoProductions]

When you have failures like this one, you may want to look at the voltage at the inverter terminals. If they are good, it is probably the inverter. If that is low, check the voltage at the battery terminals. If they are good, it could be the wires. Also, check the voltage drop along each wire. Something may supprise you. Even though the cables may be large enough, running a second cable may help.

[@michaelparks3106]

I use the same Victron MultiPlus II in my RV, powered by two 300AH Weize batteries. They are about the same $/AH as the LiTime but include low temp protection. The Victron MulitPlus II is expensive, but it's awesome!

[@brianbateman4886]

I too bought and installed victron multiplus II and love it!

[@rafski123]

I build my van with two of these 400ah batteries, really happy with them, think the lowest SoC I got was 30% and I don't bother looking at the meter anymore, just works for our weekend trips. Do think if you are DYI, 12v is much safer. As for low temp, don't care, followed your other video and installed the Victron square bluetooth temp monitor and that will halt charging from the controller. Think the worry here is that if each battery had their own temp sensor, you could get odd behavior, so better to have the temp low cutoff at the MPPT, not on the batteries.

[@WillProwse]

That's awesome!!!

[@WillProwse]

Yeah, very smart to control at mppt

[@markmonroe7330]

I do the same thing with the victron low temp cutoff.

[@donraptor6156]

My lead acid cells work cheaper and just as good on a weekend. Why use lithium for a weekend warrior?

[@markmonroe7330]

You do what works for you. You can Google the differences between the two but lithium has far less weight, takes up less space, last thousands more cycles. Many people feel like the extra cost is worth it, others don’t.

I sold my sailboat about 5 years ago, one of the best days of my poor decision making life. A 105ah AGM was minimum $280, usually more, and I had six, not including two start batteries. They all sucked. Marine electronics, especially the autopilot hated low voltage conditions. A constant struggle. Life would have been so much better with that 480ah battery for my house bank.

Hey Will, they also offer a 51.2V 100Ah battery that is basically the same battery but in 48V (or 4x 12.8v which is 51.2v). I've been using the 12v 400Ah in my RV for almost half a year now, no complaints at all! Coupled with a victron battery sense to protect from low temp charging.

[@Greg-gr5bb]

What did that 400ah set up cost you?

@@Greg-gr5bb The battery was €1500, I use a Victron Multiplus 12/2000, which also cost me about € 900, 650 watt of solar panels at about €1 per watt. Add a solar charge controller, cables, fuses etc and you're looking at about €4000 for the full setup.

I installed 4 of the 100ah mini's in my RV specifically because of their size and weight. Initially I was put off by the lack of low-temp cutoff; however, the batteries are installed in the electrics bay with a Magnasine inverter, AC transfer switch and Victron MPPT. Combined with the heat given off from the batteries/BMS', the bay stays warm. Just in case, I also have the Victron MPPT charge cutoff temp set to 35 F.

[@jimbirmingham5125]

A little off topic but we race dirt track cars and weight is a critical factor. Currently looking at building a 12.8v or 16v 280ah. We do not run on board charging. The battery must supply starting current for the starter. Believe that will be around 300 amps. Once started the draw is less than 10 amps.

I agree it's a PITA to work with 12v stuff, but it's just easier to convert RV's with small 12v systems. If I were to build a large RV setup I'd go with a 48v setup for sure.

[@andrewfidel2220]

Yeah, for small systems it's easier to do a drop-in 12V, but for 5kWh or greater you're better off doing 48V and adding a decent sized 48V to 12V step down converter as you'll save WAY more on the other components than it costs.

[@chriswolcott1692]

12v is still heavily used in the Marine markets. Most (if not all) marine devices are 12v. While some people with larger yachts have 48V banks for bow thrusters and windlasses and also have inverters to run kitchen appliances and sometimes washing machines, the vast majority have only 12v devices. (LED lights, Navigation lights, Chart plotters, TVs, Radios, fans, etc.)

[@paulplack490]

Will, to answer your question, I'm still building with 12V because I'm powering off-grid equipment that runs directly on 12V DC. It makes no sense for me to build at 48 volts, then have to use a switching buck regulator to get back down to 12. If I was using an inverter and powering 120V AC stuff, I'd see the value.

[@cdoublejj]

i don't mind the zip ties, i use them to hold down sensors and broken connectors in engine bays on cars

[@GaryMcKinnonUFO]

A shame that the price of these batteries is considerably higher here in the UK. Everything's so bloody expensive on this tiny island !

[@AutoAddictionMedia]

Unreal right, same here in Germany

[@GaryMcKinnonUFO]

Yes i checked some European prices, same situation.@@AutoAddictionMedia

[@WillBelden]

Yep, as an RVer who might replace everything in the next year or so, that lack of low-temp sensor is a deal breaker. Sometimes we end up in an area with sub-freezing temps from time to time, and our batts live under the front of the fifth wheel.

[@jimg5669]

As a full timer who posted before seeing yours - about 24v making more sense for us than 48v, for now- may I ask what you are using and if you have plans to change with your upgrade?

[@WillBelden]

@@jimg5669 No specific plans, per se. Just want to increase capacity, etc. for more boondocking in the desert. Right now at 4x190w solar and 4x100ah lithium batteries. Would like to bump to maybe 800ah and modify solar panels so they can be tipped to catch that low winter sun in the southwest.

[@philipwalters5254]

​@WillBelden sounds like you need more solar .. I am putting 950w in Summer and option 1900 total for winter (at this time I might never do winter but having the option on my camper . 200ah-400ah batteries

[@WillBelden]

@@philipwalters5254 We probably do need more solar, I'm sure. Not only "more" but "newer, more effective". Our panels are probably about 6 years old. We're sitting here in Mexico right now. The event is all boondocking, but we aren't parallel to the sun's low path, so without the ability to tip them (not that it would a be 100% solution, angle is still wrong), we're having to run the generator a couple, three hours a day. Fortunately, we're a toyhauler with 60 gallons of fuel!

[@philipwalters5254]

@WillBelden I am doing a cargo camper conversion and going to cover all the roof with ability to tilt any 4 directions.. using removable locking pins . U need enough solar to charge those batteries.. more batteries won't help until you get more solar.. I am buying four 460w bi facial panels for $200 usd each. I would guess I could get 4kw of charging power per day down there in winter..

[@pelle7575]

Most important to have proper data sheet about temp protection + warnings for coold chargeing. Checking cell datasheet of cells used in the pack you should start to worry for hi current chargeing much earlier than 0 celsius. 5 celsius would be better.

[@bdiver6445]

Hey @WillProwse, can you talk about the BMS for the 460 a bit ? Do you happen to have the specs for the 460Ah battery, Litime will not send it until I pay for the batteries and then say it is only attached to the Battery then, the quote was "But you can rest assured that the BMS of all our batteries are of very good quality." "We are sorry, but there is no way to provide you with specific information on BMS specifications. Unfortunately, we can't cooperate this time." This is for a 12V system in a Marine (Sailboat) environment, plan to use three 460AH batteries for the house bank.

[@user-if6jv6ws7o]

It would be great if you could test the new "core" battery's with internal heaters!

[@budmartin3344]

Great testing on the inverter,s that LF Victron is 3000VA/2400W and it beats the HF Giandel 4000W.

[@cb.7814]

Love your videos Will. We're looking into building a large solar & 48v lithium system for our house. Could you discuss any issues with potential fire concerns? Thanks!

[@cb.7814]

We've been thinking about having the batteries in our finished basement

[@danielnicholls6868]

nice thing about 4x 12 volt minis is you can change the voltage later by putting in series

[@kriskulczynski8957]

Thank u for your videos,bro

[@RollinHomies]

12v vs 48v completely depends on how much solar you plan to use. Especially if we’re talking about mobile lifestyles. 48v doesn’t make sense if you can’t get over 3kw of panels. 24, is the sweet spot.

[@vincentjean6756]

It would be cool if you could update us with a video where you review latest DIY Lipo builds... are they still cheaper? Worth it compared to pre-made ones? Thanks!

[@charleswoods4830]

Would you consider looking at the Bioenno batteries thank you for your time. I really enjoy your videos.

[@questionitall33]

Learning a lot from your book and videos. What resistor are you using to avoid sparks when connecting the inverter? Are all inverters floating neutral. Wondering if that makes a difference when powering a furnace vs. the lift motor? I'm using the Li Time Minis and Li Time 3000 watt inverter.

[@jvricklefs]

you have to use the screw terminals to get that load

[@cambobby2011]

It's not the only small one. There's also the Premium Power Queen. It's supposed to be really good also.

[@jasonkubitz9410]

Hey Will, I've watched a bunch of your videos and I think I'll try one of these Li Time batteries for my RV. I don't need much, just enough for the coffee maker and TVs. Maybe the microwave. The ACs will be run off of the on board genset. I'll also be running a GoPower inverter with 50amp pass through and a seperate transfer switch. That way no matter what, I can have shore power, the genset, and the inverter all running but my priority will be set by my transfer switch. Anywho, I don't see temps go below 30°F here too often so do I really need the low temp protection? My current 100Ah lithium battery I have on there now seems OK after the last 3 years and I always keep my RV plugged in. Any advice on the low temp sensor and/or advice on the best way to wire up my RV would be much appreciated. I learn better with schematics BTW. Thanks

[@Fluffywings84]

The issue with the BMS tripping is poor protection settings. There should be a delay of 1-2 cycles (2 / 60th of a second) in the BMS to account for motor inrush currents. Typically we program instantaneous for 6-8 times the full load to account for motor inrush.

[@greenisleoverland6469]

Totally Off Topic Will, but have you ever done anything with old APC UPS power backup systems? I've two older units and wondered if I can use them for power storage for a solar charging system.

[@FTFO_Media]

Will: “there all different, you never know what you’re gonna get.” Sooo..you’re say they’re like a box of chocolates? Great video as usual.

[@exploreoutthere6678]

I had issues with charging two of the trolling batteries. I bought a pair of them and both would only charge to 12.8v following the instructions. Even after contacting the company several times and using the trouble shooting methodes given. They did let me return them with no problem. I gave them a second chance and bought two of the other 100ah batteries and they charged to 13.4v each no problem and I'm happy with them. I used one of the Li Time 20 amp chargers with both applications.

[@AutoAddictionMedia]

You should charge them to 14.4V absorption, 13.8V float. 13.4V is too low

[@exploreoutthere6678]

13.4 is as high as the lithium charger would charge before shutting off @@AutoAddictionMedia

[@jamesherron9969]

I don’t use 12 V anymore but I do use 24 V. I prefer it over the 48 less hassles less concerns. And the 12 V batteries are cheaper per amp than the larger Voltage batteries

[@jimg5669]

I suspect we RVers, who've been with you since... back then ( 😄 ), are going to 24v (I'm trying to myself) but 48v in mobile systems appears to carry extra costs. Both in dollars and parasitic draw. We have limited space for panels and those lovely server racks suck up quite a bit at idle (comparatively).

[@johnbaker5299]

Are you going to test any sodium ions in the future? I have seen a few other people playing around with them but I like the way you explain things with good visuals..

[@LanceMcCormick]

Love Li Time Batteries and Victron Inverter 3000 All your fault! Ha Have 8 200 ah's with Multi plus 2 in our rig from your info. We are about self-sufficient cept gas! Keep up geat work.

[@josehiramriveragonzalez2181]

Can the 460ah battery be configurated in series to make a 24v or 48v applications? I'm very interested on buying some!! I really liked what Will showed us here! Thanks for sharing your knowledge with everyone thabks to you after Maria hit Puerto Rico I was the only one with power 24/7 and no noise in my neighborhood for real! 😂 you're the man! 🙋‍♂️
