Protecting your investment with the Smart Battery Power Control Board. 

The Internal battery protection system (BPS) is designed to automatically protect the battery cells from any accidental damage outside of the battery case.

The Power Control Board will automatically shut the battery down by internally disconnecting the terminal posts if the battery is being drained lower than 8 volts. This prevents accidentally discharging the battery too low and damaging the cells.
