Alright well I have the leaf ebike 1500w 48v ebike kit on a 29 inch tire rwd with LCD screen that shows watt draw etc. At the time it was $600 3 years ish ago shipped from Germany. The controller I assume has 63v capacitors. Right now I run a 3-4 year old ping 48v battery that at full charge I think is 54.4 ish volts 13s. I want to build a LMO 18650 pack but wondering how many series I can go? I just got in 300 vtc6 clones I would like to go 15s10p but I am not sure i can do this with a 45-60 amp bms.
