I have some Turli 200ah server rack batteries. I need to remove the busbars and BMS connections to top balance some of them. The BMS is in the front compartment and I can't reach the plugs so I have to remove the + and - connections to the BMS first, then the connections to the cells. The mfg. video shows unplugging the leads to the cells before disconnecting the power connections and the cell connections. The battery is shut off and disconnected from all of the others. Will it hurt the BMS if the plugs for the leads to the cells are NOT disconnected first? Suggestions will be greatly appreciated.
