Day 6 of Parallel Charging 48V 100Ah LifePo Battery Bank. Should I be concerned?
I'm top balancing a 48V 100Ah battery bank (16S) and am 6 days into the charging process. The cells started off at an average voltage of 3V and now they range from 3.334V to 3.325V. I have a tiny power supply which I set to 3.65V @ 5A to charge the lifepo4 batteries. The voltage displayed on the power supply has slowly risen as the batteries charge, but it's been stuck at 3.61V for over a day. I think it's still charging because the the Constant Current LED is on, and I do measure ~4A going through with a dc clamp meter. I'm just wondering how much longer am I going to have to wait?
