I just received my 4S 280 ah lifepo4 battery.....
all the cells are at 3.22-3.23 V individually
Wabt to charge them individually before assembling ,
connected a cell on my power supply ( similar to the one Will recommends ) ajusted to 3,65 no amps when verifying voltage
connect leads on battery , amps go to 4,45 ......
after 30 minutes , reajusted to 3,65 unloaded
reconnect leads around 4,5 amps
3 hres later , same amps reading but battery is at 3.28 V
3 hres later same amps reading battery at 3.30 V
3 am ( 4 hres later ) same amps battery still at 3.30 V
8h am ( more then 12 hres after initial start ) same amps reading and same 3,30 Volts
seems it wont go over 3,30 volts and how come amps reading doesnt go down ?
for now ,I moved on second cell ......
what s wrong ? Have i done something wrong ?
Hope I dint damage anything
thanks
