This is awesome. This is approaching my vision of what LFP batteries should be like. Set it on the ground, wire 4 in series, connect them to the inverter, all DIY friendly, no stupid $2000-of-labor professional installation process

[@darthtater]

Fantastic battery. Send this to DCS to show them how it’s done properly.

[@LithiumSolar]

No thanks - don't want anything to do with that company.

[@theneverman]

Sniper. :)

[@alanperkins5530]

I purchase this battery in March 2024 and installed in my 5th wheel with a 3000W inverter. I love it. Great for not having to run a generator unless I need AC ( however, I did accidently run the AC off the inverter for about 3 hours). I have also used it during scheduled power outages at my house for my home office and refrigerators. I have a 1000W of solar to charge it.

[@john_in_phoenix]

Really a superior quality battery. A tad expensive, but you get what you pay for. I think this would also make a superior 24v battery, hopefully they will come out with one. The cables required for 12v are really difficult to work with.

[@immrnoidall]

The build quality of that battery is nice.The Amazon price is really a steal.

[@moochie7480]

Not ready for one yet but thanks for the heads up and saving us dollars

[@SimpleCarGuy]

Well done! Enjoyed the video and info

[@Count_Smackula]

Good looking, well constructed battery. 👍🏻

[@WillProwse]

Wow! Not bad

[@LithiumSolar]

Did you find anything that I'm missing lol? I see a few are mentioning concerns over the cable thickness. I may do some further testing there - need to pick up another inverter.

[@quartamile]

​@@LithiumSolar the low temp charging shut off needs tested. We learned from Will that some advertise this function but sometimes it doesn't work unfortunately. Thank you!!

[@12vLife]

@@LithiumSolarMine read 485AH for a week. Safe to keep these at 100%+ for long periods?

[@theneverman]

The pressure relief valve of my rotomolded cooler seemed silly until I came down from 6,000 feet elevation, back to my home at ~230 feet elevation, couldn't open my cooler, twisted the valve and the pressure equalized. So I do see a benefit should that case be well sealed to have the ability to vent.

[@davidniquot6423]

Nicely built .. !

[@ericjansen9042]

I watched your video, was impressed, bought one, and 4 weeks later I think I have to return it. I've been gone for 3 of those weeks, but I would find that the inverter kept shutting off, and I thought the issue was the inverter. The thing had almost no load on it. It's like the BMS would go to sleep. Further research showed that people found that it didn't reliably detect loads under 1Amp, which maybe that's what's happening with mine. It's in my shed, and when idle just powers the charge controller, inverter (which I mainly use to power several other battery chargers), some DC powered LED lights that come on via motion sensor, and a thermostatically controlled fan. Anyhow, I'm pretty sure there's some issue with the BMS. We'll see how their support is but being that my return window closes in two days, I hope they reply with a fix very soon.

[@marcfruchtman9473]

Thank you for the review.

[@patrickmclaughlin6013]

Gezz, these batteries are getting so much cheaper and better then just 4 years ago.

[@jar407]

same thing happened with the pc computers the r and d tooling and development costs get paid off and improvement's in quality usually follow to a point then it starts ad this ad another feature and costs start getting higher and basics get cheaper but then everyone wants the upgrade pickups are prime example 6 cy stick trucks were cheaper than most cars until loaded with too many features cost got to point 90% of pickup buyers who really need a work truck cannot find anything but super plush 80-100k ones with interiors you hate to wear work boots or dirty pants in

[@alancole1394]

Would like to see a temp sensor test on this🔥❄️, otherwise looks like a great battery.

[@P_RO_]

Considering how many don't get that right and how easy it is to do, an actual test is mandatory IMHO

[@LithiumSolar]

I skipped the test this time because it's a JBD BMS (we know the quality of those) and we checked the programmed settings in the software.

[@HardcoreFourSix]

I see that it has low temp charging protection. I did not see anything about self-heating. If this is correct, then using this in an RV or similar situation would require a heating pad. Do I have this right?

[@LithiumSolar]

This battery does not have any heating functionality.

[@clarencewiles963]

Clean 🧼 with good quality Thumbs up 👍

[@quartamile]

Thank you! One extremely critical thing we really need to test in all batteries is the low temp charging shut off function; I've seen batteries advertise this and it not work. If a lithium battery accidentally gets charged during freezing, it's lifespan gets shot. Are you able to perform this test? Seems like a great quality product at a decent price! Thank you!

[@12vLife]

Thanks for this! I've been running this battery in my micro camper van and I LOVE IT. Its game changing for me, allowing me to run Air Conditioning. I am wondering if anybody charges these to 100% and down to 0% repeatedly? Some feel it's not as damaging as we have been lead to believe.

[@jadu79]

in the data sheet you know it said 1800 cycles at 45C so they took it on the safe side since the highest and lowest volts it is probably good to change to to improve the life span

[@ScottDLR]

I clicked on the link you provided for this battery and if you scroll down to the second image it boasts "5000 cycles".

[@drneedles7093]

That's relative excellent value for a case battery. Needs a disconnect breaker. I'm waiting for a reasonable priced case kit w/o bms for my raw cells.

[@Dturn77]

I’m thinking of doing the same thing. I saw one made by Seplos for pretty cheap

[@drneedles7093]

@@Dturn77 $600+ last I checked. $200 is max I'm willing to pay.

[@samuelfox8126]

I see on Amazon they have a 12v 300ah mini. Could you get that and review it?

[@shelley131]

I like 12V systems as I am familiar. I wish I had this battery though. I just finished doing a diy portable power station using EG4 inverter and the LL battery and was quite simple to connect but confusing with the manual I had. Also easier to find an inverter or charger for the 12V system and don't like that the my system in idle consumes 50W an hour. Just me not liking 48V but I have one now. As always great video.

[@moonobservergilles5730]

quality detailes battery nice

[@Roll2Videos]

Very good 👍

[@vdivanov]

Yeah, the evolution of these batteries is nothing short of staggering. And we need more of them to secure energy resiliency and independence. How does everyone feel about side-mounted terminals?

[@Anchor2012]

Great, and its a steel box too, so you could easily attach a better cover if you needed to.

[@Sylvan_dB]

That's a pretty battery. Looks like a good design and build except for the wiring. 2ga starts getting really hot as it nears 200amps so no way is that going to sustain 250amps. The 3x6ga fails about the same amperage. Sure seems like a natural to build a 24v in that chassis but probably wouldn't be popular enough.

[@LithiumSolar]

I agree, the market for 24V batteries is rather small. Most will make the step directly to 48V if a 12V system does not have adequate capacity.

[@john_in_phoenix]

I've been using 24v due to ampacity ratings, and the ability to fit a usable system onto a "crash cart" system. Much easier to run a 3000va Victron at 24v rather than 12v. Unfortunately I agree, not much of a market for 24v systems.

[@peckerpeter2078]

You’re forced to do bare minimum 24v…amps need to be decreased for proper wire sizing. Those aluminum busbars are going to be super overheating as well. Don’t know why manufactures insist on using that cheap ass. Aluminum…copper is far more superior for heat and amperage plus electrical conductivity.. 48 V is a nice system. The only problem is there’s not too many components that you can find easily that will run on 48 V …12 V is fine for low amperage components as they are plentiful. 24 V and 36 V have more of a selection at a reasonable price point.. The higher the amperage the higher the heat… More Strain on components..

[@bullseye-not]

Temgot website indicates 5000+ cycles.👍👍

[@robertwarner3191]

great video, I am planning on buying this battery. I have an atc camper. it has 1 battle born 100ah one solar panel. with 100 watt inverter. what else do i need to be able to boondock for a week or so? also can both these batteries be hooked up together?

[@jabroni6199]

Do these batteries need an actual “charger” to charge or is the charging logic built into the battery and we just need a power supply?

[@LithiumSolar]

You need a charger rated for LiFePO4 batteries.

[@goodcitizen4587]

So cool. Altho I'm staying 48V these days.

[@RollinHomies]

There are probably over 1000 different styles of lithium battery options just at 12v, now. And they still just keep cranking them out of china (and some US manufacturers). I imagine 100ah batteries are going to be $100-$150 by next year

[@servofyah4392]

Is the temgot 12V 300ah battery made the same?

[@LithiumSolar]

I have not looked at their 300Ah battery so I am unable to answer unfortunately.

[@hedleypepper1838]

Don't grade a eve cells now have the double screw welded terminals now ? Maybe these are older used cells, hence the 2000 cycle life

[@hedleypepper1838]

Or even old stck that has calendar aged already 😢

[@LithiumSolar]

I'm not sure how to answer this. These do not have the double screw terminals so obviously they either ordered a different terminal style or without terminals and welded themselves.

[@Laserguy2009]

Why does the app show this as a 4-cell battery when it is actually an 8 cell???

[@LithiumSolar]

The cells are wired in parallel sets of 2, so while there are physically 8 cells, there are only 4 electrically.
