I bought a LG and a Samsung pack which ran $10 plus shipping
I also bought off brand $5 packs which were dead.
well, ALL of them I received where dead except 1 off brand pack.
I took apart an off brand pack and I could recover 4 cells out of 20, but the 4 drops down to bit below 4 volts after a week of sitting.
the LG will not hold charge and dropped to 5 volts after slow charging at 150mA for many many many hours.
The Samsung I am going to check the voltage today and once I receive my load testing stuff off Ali, I will test it and recharge it.
Personally, I will not buy any more of these packs, these more than 11 year old packs probably and not worth my time to mess with. How I have to drive to lowes to drop off the bad cells for recycle.
The BMS is a 10S, some have this white glue stuff around the balance cable socket and other parts.
