Thanks for watching and taking time to comment, it is appreciated

[@bobscullion3533]

Thanks for the video, looking at purchasing 2 and having them in parallel in my next camper build. One thing i did notice is they said they can be charged 2 ways, solar and battery charger via 230v, i assume they are ok to charge via a B2B from the vehicles battery/alternator too. Thanks again, enjoy the videos 👍

Thanks for the review and teardown. Here in canada dc house was the seller of eco worthy batteries on amazon. Now they have their own brand and eco worthy seems to prefer to sell direct from their website. I have several smaller eco worthy that are great. Might try the dc house for next project as they are the cheapest in canada on amazon and construction seems great.

[@michaelkinder5144]

Cracking, well done. Like you, I paid a hell of a lot more for the Ecoworthy. The Ecoworthy 280ah is £470. That's my next purchase. I could barely buy the cells for that.

[@DCGUY]

Thanks for watching and taking time to comment it's appreciated

[@barrydavies2977]

Looks like a great budget buy. No Bluetooth or low temp protection and, more importantly, over discharging, are the only minuses.

[@DCGUY]

The price is very competitive for sure but hopefully people watching and buying these will be careful not to charge them frozen or over discharge.

[@Dirt-Diggler]

7.5v will destroy the cells 😮 run LFP under 2.5v per cell and dendrites start to form, do it often enough and the cell will short out 😢 I recon these are failed QC units that have been sold on as per the usual Chinese way of business, it's also why they company thinks there are cylindrical cells in there and there's only 2 ways to charge it IE they don't have a clue about the product, it's fine saying an inverter will shut off before damaging the battery but not every load has a voltage shut down. The BMS should save the battery not let it get damaged !!

[@DCGUY]

@Dirt-Diggler That would make complete sense, it's a very cheap bms albeit a JBD and yes if it won't protect the cells its useless. I wonder if it could handle a short, maybe i will find that out. It took a charge at least.

[@jasonbeason4780]

I just bought one from eBay, and it was only 189 USD. Also had a 4th of July sale on it. 38 off 189 USD. I'm glad to see it is a great quality battery. I'll be using mine on my 15-foot tri hull fishing boat for lights and trolling motor. My engine doesn't use a battery. It's an 18hp evinrude 1967 model. Tha KS for this video. Have a great day

[@jasonbeason4780]

@buddyrogers4538 it does great. Runs my led lights and trolling motor great. It's a big battery but a lightweight.

[@ProMace]

Fantastic work mate. Exactly what I was looking for. I do have one worry about these batteries. If they're supposed to last 10 years, isn't a 3 year warranty a bit short? What's the catch? Or is this normal in the battery world?

[@DCGUY]

Thanks for watching and taking the time to comment. I personally take any long-term warranty with a grain of salt. Will any of these companies be around in 5 years? The chemistry used in the cells Lifepo4 will probably last longer than any company selling them. On the whole they are very reliable and with proper care will last many years ( much longer than any Fla) Also I reckon if things we're to go wrong it would most likely happen within the warranty periods given. Some companies give a years warranty, others up to ten years.

[@johnshaw359]

Wow, I took a punt on one of these, I feel like buying another after seeing this. Obviously well constructed.

[@DCGUY]

Built quality has really improved over the last year.

[@tjsmith3060]

These worked fine in a 36v resistor golf cart. Never shut off flooring it or up hills.

[@DCGUY]

Good to know thanks

[@MalinowyWampir]

Thank you for the test! Looks like the bms has such low voltage cutoff to pass the advertised capacity of the whole pack. This also leads to faster cell degradation. I'll pass.

[@gazzamundo]

How big of an issue is not having a low temperature sensor? I'm in the UK and have solar panels on my camper, would the charge from the panels damage the battery if temperature drops to 0c or below? FYI....The solar charge controller is built into my Renogy DC-DC charger. Great work on the channel, really informative.

[@DCGUY]

Hi, tha for watching and taking time to comment. Unfortunately, Lifepo4 batteries will be damaged below 0 degrees if charged. unless your charge source has low temperature charge protection built in. While you can actually discharge a frozen Lifepo4 Battery, you just can't charge it. I am not sure if your unit has any low temp charge protection but worth investigating. If you have an existing battery you can try insulate it or add a 12V thermostatic relay to control a heating pad during cold snaps. If you have yet to buy a battery, you are best to get one with low temperature charge protection built in via the BMS.

[@gazzamundo]

@@DCGUY Hey, thanks very much for the detailed response, I've just checked by chargers manual and it states that is will stop the charging when temperature is below 1c if the battery mode is set to lithium so I think I'm good to go for the DC House battery after all. Thanks again

[@DCGUY]

@@gazzamundo that's awesome

[@matthewwakeham2206]

I ordered the DC House 24 volt 100ah off ebay and received an ecoworthy battery in an umarked box (shouldn't lithium batteries be marked and use special couriers)? If you follow ecoworthy/dc house state of charge chart you would believe the battery is faulty or only has half the stated capacity. They say 26.42 volts is 30% when in reality 26.1 is around 50% resting voltage. In truth if charging and discharging the voltage is completely irrelevant for state of charge which is why I'm glad I bought a shunt to measure ah in and out. It appears that for a charge/discharge of 0.1C (10 amps) you can probably get more than 100ah out of this battery. Also I learned that while ecoworthy say 29.2 is the charged voltage that seems to be where the BMS will disconnect. If using a solar charge controller you need to set the maximum voltage to be 28.4v or less otherwise you'll be bouncing off the disconnect everytime the sun appears from behind a cloud. Mine is now set for 27.8. Hopefully that is high enough for cell balancing as ecoworthy say their bms balances at 3.6 volts per cell but seeing as most of their information is wrong I'm hoping that it is actually around 3.4 volts per cell. I know that fully charged is around 27.7v if you can look at the charging voltage graph (using the shunt). It hits that voltage and pretty much stops taking any current and the voltage shoots up. A lot to learn about charging/discharging lithium batteries! Now I just need some bigger solar panels so I can charge the battery in one day!

[@nicothanheuser1178]

So glad you uploaded a video on this one. Bought it straight away. I remember subscribing 2 years ago. Still so much value! Since it doesnt have a screen. Whats the cheapest shunt u can recommend for this battery. I dont need bluetooth or something. Took a glimpse on a few on ali express but not sure what to buy though.

[@DCGUY]

Any shunt will work for example this amzn.to/49Dppa8 and check on ebay too

[@sun-sea-solar]

Would be interested in their 48v battery

[@markeh1971]

Have you seen their latest Leisure battery, 100ah with a different case? The case includes USB A & C PD with charging at 45w by USB C. There is also a DC 5mm socket at 5a. It also has a carry Handel!

[@DCGUY]

Yes I am aware of it but haven't physically seen one yet. If they send me one, I will definitely check it out.

[@markeh1971]

@@DCGUYHi, just brought the 200ah 12v battery. They are bigger but would make life easy by cutting down wiring whilst being a little physically bigger. They also do 500a for 10 seconds so two would cover most 12v inverters and have a good capacity. Still like the Leisure battery with USB C & A which are out of stock! Take care M.

[@pd-g3960]

Thanks for the detailed teardown, if you could buy the eco-worthy battery for a similar price, which one would you go for?

[@DCGUY]

From my own findings there was no difference between them. The DC HOUSE are re badged eco worthy units, exact same warranty period and the dc house usually cost less. So I would go with the cheaper option. Also look at fogstar eco units coming August

[@benv5243]

Forgive me if I missed something but you said the relatively small BMS gave some doubts regarding series connection. Just to clarify, the manufacturer confirms up to 4 can be used in series and/or parallel. Is this right?

[@DCGUY]

Yes they say that in their marketing materials, same with the Eco-worthy claims but I personally wouldn't use more than 3 in parallel or 2 in series to err on the side of caution

[@AlPottoff]

Sorry for daft question but would using 4 of these in a 2s2P configuration going to cause any issues?

[@DCGUY]

I wouldn't imagine so, plus you will be able to monitor each battery. Just make sure you charge each battery and then let them sit in parallel to equalise fully before connecting in series. The BMS may be fine for a 4s set up as claimed by the manufacturer, just I don't have enough data to make a firm call.

How is this battery performing since the teardown? I bought the newer model of this battery with built in USB ports. Looking at the specifications, it seems to have the same bms though. Thanks for the information.

So far so good in my own set up. I didn't know they had units with USB ports.

[@SpyderNow1]

[@tjsmith3060]

I would love to see if it can reach its 400a surge current for 10 seconds.

[@matthewwakeham2206]

Most of the info seems pretty random to me. Maybe the cells could do that but whether the bms could is another matter.

[@dunk8157]

Its a shame the cutoff is so low, that could damage the cells, also they advertise low temp cutoff but it seems to be false advertising. They are £199 now so pretty cheap assuming you can deal with these issues.

[@valentinseyfried5484]

You measure 13.27V at the charged state. But in the manual it says the 100% SoC is at 13,46V. Why is that?

[@DCGUY]

The voltage settles, lifepo4 doesn't behave like FLA and that's why you can't really use voltage as an accurate state of charge.

[@davidcharleston1314]

[@luketilley9137]

I have zero knowledge of batteries. Would 2 of these work for my 70# thrust 24v trolling motor?

[@DCGUY]

Yes, absolutely but a single 24V unit would probably be less expensive that 2 x 12V.

[@timkent6606]

Can these DC house batteries be installed on their side? seems some LI batteries can and other cannot and it is not always apparent when you can or not

[@DCGUY]

One of the benefits of lifepo4 over lead acid is the fact you can position them any way you want to fulfill your needs.

[@david78212]

Interesting battery. Although the tear downs are interesting, I’m not really concerned about the BMS being zip tied. Giving the stationary place my batteries will be in, the BMS could be held in with bubblegum and I don’t think I would care or ever even know. I do like to see what they are made of, but the next batch could have different components all together and you would never know unless you tear the battery apart… the only way to make sure what your battery is made of is to build your own. I’ve watched a video of a tear down and the battery that they had bought 1 year ago was completely different inside, had a different BMS and instead of 4 cells, it ha groups of 5 20ah cells. So just basic not really stressing the battery out, what’s inside is kinda pointless. If you plan on working your battery really hard all the time, you shouldn’t be looking at an off-the-shelf 100ah battery in the first place. With my intended use, it would be fine.

[@carlfielding2082]

There's a 200ah one now!!! We need the teardown!

[@DCGUY]

I've seen that too. Would be interesting to see how that's put together

[@maithem212]

Nice tear down! I have an eco-worthy 12V 100AH battery - think I can buy one of these to hook them up in series, or best stick to second eco-worthy battery?

[@DCGUY]

They are the exact same batteries from what I know, should not be an issue. Same cells and bms units.

[@ingmarnoteboom]

The capacity was 104Ah when drained to 7,5 volts and you're saying the capacity would still be 100Ah with a cutoff at 10 volts? that seems highly unlikely, can you explain?

[@spacelord1913]

with lithium iron phosphate batteries the capacity drop off is extremely steep, almost vertical, once you go below a certain voltage.

[@kevinnichol4649]

Great informative video. Would it be safe to run 3x of these batteries to cope with running my 12v fridge etc. Also could you recommend what size solar panels would be suitable to keep the batteries charged.

[@DCGUY]

3 in parallel should be fine and rule of thumb is 200w solar per 100ah battery with min 30a scc. You can find more info on my website about how to choose items.

[@messiahmindset2964]

The new 200ah version says can have 4 to a string with 48v X 4 in a bank with a whopping 52kw!

[@SmallVansBigWorld]

Only major issue with the build actually is cell compression. I noticed no effort for them to keep the cells compressed.

[@DCGUY]

Cell compression seems to be something of a personal preference. Some like to leave a small gap for heat dissipation while others want to fully compress the cells. Personally, I am on the fence when it comes to compressing cells for long term use. Guess time and actual data will help sway me.

[@SmallVansBigWorld]

@DCGUY from what I've seen most cell manufacturers recommend compression. Logically makes sense especially when the battery is charged up to 100% regularly. That higher voltage seems to want to expand the cells.

[@DCGUY]

@@SmallVansBigWorld yes, cells will want to expand and I've seen some data that suggests compression is a good thing to do, but they are short term use studies. Heat in my own opinion will simply speed up the degradation process, but again only my thoughts.

[@Kev.i.n28]

Thanks for the video. Looks like a decent battery for the money, Certainly cheaper than the Ecoworthy's i purchased last year. I would purchase a few but have a 12v system with 4 ecoworty in parallel already. How would i add additional capacity whilst keeping it 12v?

[@DCGUY]

Theoretically speaking you can have as many batteries in parallel you want, but I wouldn't recommend you do that. 4 lifepo4 is an acceptable set up and you could simply replicate what you have already and tie them at a common bus bar with independent Fuses for each bank of batteries. I use MRBF Fuses on each battery post, then an ANL and finally a class T fuse from the banks going to the inverter.

[@Kev.i.n28]

@@DCGUY Many thanks for the reply, so each bank connects to a bus bar and inverter also connects to bus bar? what is the benefit of a class t fuse over ANL on line to inverter on 12v? I also see from your website the MRBF are no longer available via your link.

[@DCGUY]

Thanks for letting me know about the broken link. A class T fuse is much faster acting and eliminates any potential for arcing. How are you recharging your batteries at the moment? Would you have the capacity to charge more? As I am considered a small power consumer I have 2 seperate banks of batteries and can choose to use power from both banks simultaneously or individually using a 4 way switch depending on my needs. I also have a separate charge feed going to each bank and while it's not everyone's ideal set up it works for me at the moment, so I can charge a bank while using the other or charge both at same time via mains or solar. So negatives from both banks go to a common neutral Busbar and the positives ( each fused) go to the switch and then via class t to my 3500w inverter.

[@Kev.i.n28]

@@DCGUY Yes i watched the video where you were showing your battery set-up via the switch. Similar to yourself my solar is on a shed, 1kw solar at present, not so good with Scottish winters i top them up occasionally via mains charger, but produces more than enough in the summer. I may try a 2 bank setup. Thanks again for the information and keep up the good work.

[@DCGUY]

You should be good to go as they are designed as drop in replacement for traditional lead acid but it's a good idea to see if your B2B has a lithium profile to get the best from the Lifepo4 units.

[@tizianod]

Ordered one to be installed on a small boat. Can you recommend a good DCDC for the alternator and a AC charger? Or can we use the existing charger for lead acid?

[@DCGUY]

Unfortunately I have not personally used a DC to DC charger so cannot make any specific recommendations. Victron, Renogy and even Eco-Worthy have DC-DC chargers available in various amps. Higher the amps the faster your battery will charge. eg a 20A charger will recharge a fully depleted battery in 5 hours whereas a 50A charger will recharge the same battery in 2 hours. Same with the AC chargers. I have a Victron ip22 30A AC charger and a Noco smart charger 15A but any charger with Lifepo4 charge profiles will work. I see Fogstar now sell lifepo4 chargers too. Using a charger designed for FLA is not advisable as they use a totally different charge algorithm

[@tizianod]

[@300dymanite]

What should the bulk / float be set to on my solar controller? It's a cheaper one so doesn't have presets. Also I've set it up with a renology 40a dcdc charger. The settings for that imply it should be charged at 14.6 but that seems too high. Got it all installed just need to make sure I'm not going to destroy it with incorrect charging

[@DCGUY]

While some battery manufacturers actually suggest 14.6V (3.65v per cell) I personally like to go to 14.2V with float at 13.5v which is what my Victron Charger is set too.

[@svetsor]

I asked dc house about the 7.5 V cutoff and they replied "Normally the battery will cut off between the voltages of 9v and 10v.". Anyone with more info on this?

[@DCGUY]

Being a JBD BMS I did expect it to stop at 10V but saying that even the Renogy Pro I tested went well below and even went into protect mode. Fortunately the dchouse accepted charge again with no issue. Most inverters will cut off at 10V anyway before the battery does so if you use a dchouse just use a shunt to ensure you don't go below 10V if your not sure of the inverter cut off voltage

[@guywhoknows]

That's not a great deal, it's about twice the price.. The BMS system used on the cheap (affordable) batteries always have issues, I have one in and the low voltage cut off it too high I'm waiting to take delivery of another, hope that runs better. It's in a metal case, with screws, so at least I can get in there to upgrade the hardware.

If you are using 12 volts, then the inverter has the potential to pull 250 amps so you should use 40mm cable and a minimum 250 amp fuse. However, if its 24V the Amps will be 125 and a 20mm² cable. Also check what size BMS the battery is using, if its a 100 amp unit that will limit you to a maximum of 100 amps from the battery at any given time and if it is a 200 amp BMS again that will restrict you too 200 amps maximum.

Second stuff is big price, LFP cells are cheaper and cheaper and I build 12/23/36/48v banks and price is like half of that one, try, LowVoltage is easy. I operate mostly at 280ah and more, for only one aku it's costs but if someone do in that, it's cheap to build one.

If your doing a lot of builds and the bigger the system then yes the costs are less

@@DCGUY Maybe other word sentence, a parts, import them, travel costs with tax etc. is half that price. DIY person pay 50% if this one to do that. Company who need profit, warranty, space to store them.. it's a proper for 50% - this is question we need think. BR from Poland.

Thanks for watching and taking time to comment

Did you use just a normal smart charger to charge it, and what setting did you have it on?

[@DCGUY]

Just a regular 10 amp battery charger I had normally used for my FLA battery.
