Voltage-sensitive switch

This switch recognizes the charge level of both batteries (or battery banks) and provides excellent charge management for the second battery bank.
The switch connects two normally isolated banks when it recognizes a recharging source (engine alternator or battery charger). As soon as the recharging source is active, the switch recharges the first battery of the main group (engine battery). When this reaches a voltage of 13.2 V, the switch opens the circuit and recharges the second battery (service battery).
The switch also acts as an emergency parallel battery. The parallel battery can be activated manually or using the (on)/off switch on the dashboard.
Flush-mounted or external.
