Protection against deep discharge

Our low-voltage protection prevents deep discharge of your battery by means of a two-stage safety system. Acoustic and optical alarm functions warn you of an approaching deep discharge. If further current is drawn, our undervoltage protection separates connected consumers from the battery and thus protects against deep discharge.

Two batteries can also be charged without any problems via the alternator or the charger - this is ensured by our battery isolator, which can distribute the charging current both unidirectionally and bidirectionally. The charging of the batteries is almost loss-free.
