I have been trying to re-balance my 4 year old 100Ah CALB pack with mini-BMS, identifying the highest SOC cells by watching for the red LED's to light up on the mini-BMS boards on the individual cells. I have been using a 12 volt, 50 watt "A" lamp, leaving it on the cells one at time for 60-90 minutes each, then bringing the full pack up again until I start seeing red LED's. I don't have any other suitable DC lamps or other safe (to me) items which I can guarantee won't damage a cell by my inattention (I set an alarm for myself every time I connect this load to a cell). What suggestions do people have for me? How would a 120 volt 500 watt halogen affect one of these individual nominal 3 volt cell (resting is actually ~ 3.3v)? It was my intention 4 years ago when I re-converted the EV Escort to lithium to see if I could drive an EV for 10 years on a $10,000 layout, not counting brakes and other expendables. So far, I have seen no loss of range, and have no indications of degradation. I set myself up for the current balancing problem by charging individual cells while the PFC30 was back in Washington for a minor repair, so now I have high SOC cells turning off the charger before the pack is fully charged.
