I had learned after charging up each battery, ... then you connect them all in parallel ... no load ... and let them sit for a day or two. This actually equalizes al four (in this case) to have the same voltages. THEN you make them up into series or series parallel... just sayin and I hope this helps.

I tested their regular 12V 100AH a while back and was very impressed with it.

I have 2 of the full size 100ah ones from DJLBERMPW. Been running them daily for the past 6 months without issue. Would love the mini's but they were not out at the time i bought them. Got em for $166/ea which is a steal deal IMO.

Nice ill get one once my normal size 12v goes 😂 its heavy has like them round cells inside about maybe 30+ of it and its like 25 pounds.. when im done charging it from dead flat shut off it only gives me 92ah, before its was 95ah when new but i had it for like 2 years now kinda abuse it dead shut off flat couple times still going so its going to take me maybe 8+ more years to get my battery to a way lower capacity that ill need a new one 😂 but for 180 bucks for a mini is really tempting 😂 if they get that to 150$ it would be nice and then they can offer ones for 200$ with some fancy warmers and Bluetooth.. love the vids.. adding this to my cart 😅

I noticed this brand of 50ah battery drops to 13.2v under load after charged. But it holds at 13.2v for a long time with about a 250 watt load. The 50ah lifepo4 battery from this company does 100ah load for a short period. Not a good idea to drain more than 50ah at a time under load with a 50ah battery. Seems to be a good battery with a good bms. However a 100ah battery will do a 100ah load drain safely. Will do a little more under power surge. Good Lifepo4 batteries.

Read my Amazon 1st customer review on the 300ah variation from Dec. 2021

what size breaker you use?

Temperature cutoff?

Thanks Brad. 48V is the way to go for me. It looks like you need to have some kind of balancing going on between the batteries to run them in series like that?

Nice😀Do you like the big "normal" size batteries better?

Greetings from sunny Jamaica 🇯🇲.I have a 24v system and I recently bought 4 of these 12v 100ah battery and I am wondering if I can connect them in series parallel to make a 24v battery bank.

What tool are you using to remove the top? Any tips?

What battery charger are you using?

How long did the batteries run that 12000 btu AC?

May I ask how long it took to be totally discharged?

What inverter did you use and what power watts??

The point is it Preis corst

So, the BMS did not protect the battery? One cell hit low voltage diaconnect? That is not good!!!!

That discharge rate is low. .08C. Test it at a .2C rate and get back to me.

Doesn't exactly roll off the tongue, does it? :)

Are the batteries made in China?
