CHEAPEST Lifepo4 Battery I've Tested! Reviewing Budget 12v Battery

[@johnphillips5656]

I am glad I found this as I just bought 2 of these batteries about a month ago. I am building a powerplant and I intend to use these with solar power. I got 2 for $248.00.

[@Mikebuildss]

Nice deal! Hope they work out for your project!

[@glennr9913]

I bought 4 of these for our golf cart. Paid $520 + tax, total was $556.38 on eBay. I charged them using a Vevor 35 amp smart charger. One didn't come up to full capacity properly, so I discharged it a bit using a battery load tester. It charged fine after that. After charging them I let them sit idle for a few days, then connected them all in parallel and charged them again as a group and let them sit idle for a few more days to equalize. Then I installed them in the golf cart, connected in series, to make a 48-volt bank. I installed a 500 amp shunt with battery monitor. So far it's working fine, but I haven't driven far since the weather has been chilly here. I'm quite happy to have converted the golf cart to LiPO4 so affordably. The golf cart conversion kits using a premade 48-volt pack cost $1000 more than using individual 12-volt batteries. These fit perfectly where the previous 8-volt lead-acid batteries had been, so installation was simple.

I lucked out! I bought this to power a diesel heater in my garage. Mines worked perfectly so far.

[@Mikebuildss]

Glad to hear! Is it one of those Chinese diesel heaters? I have seen a bunch of videos on those heaters! How do you like it so far?

[@gkyahoo]

I bought 4 hysincere 100 amp batteries in temu. Temu gave me some coupons and the total cost was like 90 each , shipping included

[@mr.c6674]

Thanks for testing this. I think your camera location setup is fine.

[@Mikebuildss]

@@mr.c6674 Yes sir thanks for the feedback

[@wayneknight2654]

I bought 2 but haven’t used them yet, was curious how you released the glue to remove the top. I’m thinking about taping the wires like you did

[@Mikebuildss]

@ I usually use a flat tip screwdriver and hammer, and extresmy carefully work off the top lid from the bottom case, I work the glue joint until I can separate it. I’ve opened many batteries the key is go slow, be careful. Be safe!!!! Don’t stab it directly n you should be good

[@wayneknight2654]

@ appreciate the quick reply, gonna use mine in my travel trailer and am going to tape the wires that are next to the metal edge. Thanks for the review. I’m gonna hit the subscribe button!

[@danieltimisan6820]

price went up to 180$ for that money you can get a reputable brand , it’s not wort the risk imho

[@kostric7]

Tested mine 3 times. The best it could do was 92.3 amp hours Humsienk tried telling me it was the bms protecting the battery I ended up getting a 15$ credit cause I didn't want to pay to ship it back. also it did not have the metal framing. Beware

[@davidpopowicz7689]

What's nice is that it's slightly smaller than a Group 24 battery. Quite nice to see out of a much cheaper pack!

[@lmfarms4611]

They make regular batteries, Group 24 & 31, they also make group 24 mini's

[@TabooRevolution13]

I'm using this on my Razor. It pulls up to 300 amps then the BMS cuts it I think.

[@tobyalsip9403]

When he was asking about the camera pull it back just a little bit

[@JamesAmbrose48]

You should see the LFP batteries being sold on TEMU. I bought 2 of them that work ok except the DC USB ports on one of them stopped working. Battery itself still works fine. They’re just above $100 in price.

[@Mikebuildss]

@@JamesAmbrose48 How long does it take to arrive off temu?

[@JamesAmbrose48]

@ I think I waited about a week for the batteries. The Temu warehouse is in Massachusetts but the batteries came from an associate vendor.

[@tehpanda64]

Nice tear down and testing, I wish you had some better luck getting the temperature safety cutoffs to work. Do you think in the future after the teardown on these videos you could throw the whole battery into a chest freezer or something with the temp probe hanging out? and then get a second temperature probe on a multimeter or something to record the temperature of the air close to the bms temperature probe so we know at approximately what temperature the safety engaged at? High temp cutoff testing would be cool too, I guess a hot plate and a beaker of water + second temp probe is the way to go.

[@Mikebuildss]

@@tehpanda64 That’s a good idea may try that! May need to clean my freezer out lol!

[@maurice7413]

Some testers use a can of compressed air, with the straw, turned upside down.

[@wayneknight2654]

I’m not too concerned about the low temp cutoff, my charge controller has a plugin temp sensor that will control the low temp charge and cutoff

[@kenborghini]

Interested in how you connect this to heat pump. Please and thank you

[@wayneknight2654]

So I opened mine up and it was designed differently than yours, mine had foam rubber on sides and cells were not encased in a metal frame

[@stevencartlidge6574]

I bought the same battery a couple of months ago from TEMU. When I got it of the box I could hear something was loose inside the battery. Almost sounded like a bolt or something like that. I emailed the battery company but never heard a word from them. I did send it back and got a refund although I didn't think it was safe to be moving it around because it had a full charge and I thought I might would short out and start a fire. I will not purchase another one from them since the company never answered my email.

[@Mikebuildss]

@@stevencartlidge6574 That is not good, I usually buy from eBay or Amazon, never had to reach out over issues but I’m sure they would be more willing to help

[@mannyfragoza9652]

looks like HumSink liked your review; i cant find any for 125.00 The cheapest ive seen was US $181.24

[@Mikebuildss]

@@mannyfragoza9652 That’s a shame I’d say for that price you’d be better off maybe with a higher quality battery, but hard to say. Also check prices often battery prices are wierd they fluctuate a bunch. Good luck!

[@maurice7413]

Temu shows it for $121, but I've never bought anything on Temu. Considering the fact that they have a Dumfume 12V 100Ah LiFePO4 Lithium Battery with Built-in 100A BMS, 1280W Power Output, Up to 15000 Cycles for $72.88, not sure I'd trust them.

[@mannyfragoza9652]

@@maurice7413 i guess their pretty much like Alibaba ? Ive bought a few things from them only one item out of three ive didnt recieve.

[@jonlightsonnochaway]

I was able to get 104ah’s out of mine. I didn’t open mine up though

[@Mikebuildss]

Good to hear, so far all of the cheaper batteries ive tested ive been able to pull slightly above capacity

[@lorenrickey5481]

Where can I order your meter/tester?

[@mannyfragoza9652]

i believe Amazon has it under the name Koolertron 84.00 one that looks similar, Goupchn Battery Monitor 400A 69.00, WonVon Battery Monitor with Shunt 400A 79.99

[@craftymulligar]

You should also test out the tracker 100 ah ain't sure they are really lifepo4 or something else. But it seems they are really expensive and are a well you know. I was hoping to just go to bass pro shop without having to get it on line. Guess somebody will test them.

[@jandst.6634]

Good test and showing the build. I like the metal compression. Question, I have tested a couple of very expensive Lifep04 100 and 200 ah batteries. Friend and I found a couple of batteries that would cycle at the end of charge because a cell pack was not at capacity so the BMS would cycle end charge because the BMS detected Over Voltage Protect. Have you observed that since you are doing a full charge with a voltage that I presume is over 14.0 v. Have found good batteries might cycle a couple of times then no more charge acceptance, Jim.

[@Mikebuildss]

I normally see about 14.4 fully charged, Generally as long as the cells are matched good the pack should stay balanced.

[@jandst.6634]

@@Mikebuildss Thanks for the reply. What I was talking about is when the battery is approaching 100% and a cell is a bit less in capacity it will cause the BMS to do the OVP. In your testing I presume you have not observed this anomaly. It will cycle the charge current on and off at a rate of usually under 30 seconds. Jim.

[@Thunderst0rn]

Nice package for the money. Thanks!

[@cruikshank]

I need a charger and want a 2000W Pure Sine Wave Inverter. Do you recommend the Harbor Freight inverter. Use will be emergency power to keep our fridge running in a blackout. Also where can I buy the meter you used to test the battery? Thanks

[@Mikebuildss]

Honesty it seems to be good for the money, check video link i added the power meter.

[@rogerhargreaves2272]

Nice battery & review. Shame about those leads, they’d probably chafe if you took that camping a lot. Can’t find them on eBay U.K. though.

[@Mikebuildss]

@@rogerhargreaves2272 I bet anything it’s being sold under other brands too, agreed would not hold up to tons of vibration

Looks like same battery for $114.39 on Temu today.

[@Mikebuildss]

@@cruzer01 someone said they go on sale even cheaper sometimes if you check enough! Definitely a deal!

What type Charger for this battery?

[@Mikebuildss]

@@roybrown3018 12 volt, 4s lifep04 charger with a max voltage 14,4-14.6

[@craftymulligar]

If some people getting lower specs maybe the cells are used I would think.

[@Mikebuildss]

@@craftymulligar Hard to say with so many different brands being offered, I’m sure they are rebranded from a bigger name brand cell maker

[@maurice7413]

I certainly enjoyed the testing, but for us average users I think it would be a crap shoot to count on these really cheap batteries. If you're just playing around, sure. But if you're using them for something you need to count on, better to buy a known brand that's been around for a while.

[@Mikebuildss]

Thanks for the comment, I bought this with my own money so the companies dont know im reviewing it, that way i dont get special treatment. If the battery ever tested bad, id complain and try to get a refund or warranty it.

[@timandnatd]

$420 for a pack of 3 on amazon. That’s $140. $169 on amazon for 1
