High draw applications often require dual batteries to be installed. To properly keep a constant charge on both, choose from two voltage relays. Item no. AW75990, single sense relay, will consistently supply a simultaneous charge to both batteries, but when the battery charge falls below 12.8V DC, the VSR disengages, separating the batteries. This helps to eliminate one battery draining the other. Item no. AW75992, dual sense relay, senses the voltage of both batteries it is connected to. If either battery is receiving a charge, the VSR will activate and parallel both batteries. It is designed for applications where a battery charger or second charging unit is utilized. Ignition protected per UL1107.
