Hi,
so i just assembled my lifepo4 back, double check everything w bms and all. but when i connected the pos wire (neg has already connected to the bms neg) to the pos battery, i got sparked.
nothing else was connected to either battery nor the mppt at the time, and i was 99% sure i didnt short anything.
so question is, is that an abnormal thing? i thought spark only happens when either short or connect battery to an inverter. maybe because i connect the wire in the wrong order, as in, i should have connect the wire from the battery to the mppt instead?
after that, my overkill solar BMS didnt report anything out of ordinary. is there anything i should be worried about?
thanks much
