Could be the capacitors charging up that make it spark...does it spark if plugged in to the wall first?
Could also signify something more significant and potentially hazardous that could damage the BMS. Might be a good idea to check for continuity/resistance between the + and - output end, in case it's shorted between them somewhere.
