Does anyone have suggestions for a BMS for my lithium powered XM-3100 (it is a OEM version that came with 19 thunder-sky batteries). One of the cells caught fire during normal (right after a short trip) five of the cells were damaged. I bought 5 new ones only to find out that mixing old (be it lightly used only 3000 miles) cells and new one is not a good idea. I have two questions for the thread,
1) what it a recommended BMS for 60 volt, 19 3.2 v cells, 40 amp system?
2) if I put a BMS system can I mix the old and new cells?
