Replace new battery in Boosted board 1 gen

"You will need to replace the dead 12S1P pack of A123 26650 cells with new ones by spot welding a new pack together.

Here's a battery diagram."

"Anyone got any updates removing the old battery completely?

Following the guide: https://www.youtube.com/watch?v=z7LOwbEp... , was able to strap a secondary battery to the board, works; but the old battery is dead weight yet is still needed by the BMS.

I assume there is a message being sent back to the motor circuit."
