The Battery Protector is a microprocessor-controlled protection system designed to prevent vehicle auxiliary batteries from being discharged below or charged above their permissible operating limits. The device continuous monitors system voltage and ensures reliable power availability for superstructure equipment while maximising battery lifetime.

High-current power relay, available either as a bi-stable (latched) solenoid or an mono-stable version – both supplied separately – serving as the primary power disconnect element for the superstructure equipment.

Alarm output, used for signalling critical voltage conditions (configurable for buzzer, lamp or other low-current signalling devices).
