Voltage Sensitive Relay 12V 80A This simple device allows the charging of two separate battery banks from a single charging source such as vehicle alternator with no risk of flattening your battery bank.By sensing the main battery voltage, the VSR (voltage sensitive relay) will only connect the secondary bank to the source when the first bank is fully charged. This ensures thats secondary bank can never drain the main bank.Dual sense allows the unit to sense the voltage of both batteries that it is connected between. If either battery is receiving a charge the VSR will activate. This allows the charging of the second battery from an external battery charger or second charging source.Continuous Rating : 12VDC/80 amps Peak: 160A Engage Voltage: 13.3VDC Disengage Voltage: 12.8VDC Screw Fit Base
