Plus index and middle fingers get used a lot so a sore on the end sucks.

Have to buy a new battery? Amazon has third party ones cheap: https://amzn.to/3uxa9qu

The holes that you need to jumper say 'RST' (for reset) next to them, I believe.
There are other videos that show you how to 'boost' or charge the battery manually with another pack or charger. This is NOT that, but BOTH may be required if the pack is at 0 volts AND the BMS (Battery Management System) has placed the pack into Safe Mode or Test Mode or whatever they call it.
