Video does not work, but not needed.
Check the main leads where they attach to the bms. These are seperate from the balance wires.
If you have 42V going in to the BMS, then look HARD for a fuse, if none, then the BMS is bad. Unusual from impact alone, maybe a broken component lead or smashed chip?
Check carefully the connection for the main leads to the pack itself if not 42 at the BMS connection. This is where I would expect the breakage from shock damage to occur.
It is feasible to just totally bypass the BMS, but then you have NO protection from over-discharge, or over-charge, and no balancing. Old battery, take some safety precautions, but use it as a learning experience.
