Do not touch any terminal while power is on.
Doing so will cause electric shock.
Correctly connect the battery connector.
Do not charge, disassemble, heat, short-circuit, or solder the battery, or throw it into the fire.

Undertightening of the terminal block mounting screws or terminal screws can cause short circuit,
fire, or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
Undertightening of the module fixing screws can cause drop of the module.
Overtightening can damage the screw and/or module, resulting in drop.
