testing procedures wouldn't be much different than testing a 18650 7s pack?
The individual cells are LG jh3 in 7s configuration out of theLG Chem RESU-7H ESS I picked up last weekend. I have multiple packs that won't charge on the X8. Out of the 6 packs I may have two that will sorta charge, the rest are all very low voltage. The average voltages is 8.5 volts. so barely above 1 volt. The cells are 63 amps each when new.
I made an balance connector adapter with an 8s connector (9th wire cut off) to the two 4 wire connectors used on the packs. and tried charging two packs one of the sub 8v and 1 @ 10.22v the 10.22 pack charged to 15v in about 15 minutes it is now sitting at 14.5v, I charged it last night just to see if it would charge.
Would this work and would it be safe?
Alligator clips connected to a plastic/wood 18650 cell then placed in a dumb charger may work. I can remove the covers at either end of battery exspoing the 7 cells.
Even if none of the 6 battery packs can be recovered I have 2 heavy aluminum cases. The larger side for the batteries and the smaller side for a charge controller/solar inverter charger might fit.
