Safety recommendation: if not used, please cover the service connector by a self-sticking tape or any other adhesive cover.
This way you can prevent accidental touching of the pins by some metal objects put on the upper side of the battery.
Warning: the individual output pins are directly connected to the individual cells.
There are no fuses, nor any other protection. You must avoid any short circuit by accidental connection of the pins or by improper wiring on the opposite part of the connector.
Do not try to disassemble the service connector by removing the screws.
