Preserving battery life and providing cleaner power, the Sea Clear Power BPR Battery Paralleling Relay is designed to automatically charge your cranking and auxiliary batteries while keeping them safely isolated when the outboard engine is turned off. Supplying key advantages over an automatic charging relay (ACR), digital voltage-sensitive relay (D-VSR), or voltage-sensitive relay (VSR), the Sea Clear BPR gives you total control through features like programmable voltage settings, an integrated digital display, charging-current monitoring, and reverse current protection.

The Sea Clear BPR works by automatically connecting your auxiliary battery when the customizable charging voltage is reached so it can simultaneously charge with the starting battery. When the outboard is off and voltage once again drops below the preprogrammed level, the Sea Clear BPR isolates the batteries to preserve starting battery power.

Each Sea Clear BPR is engineered for modern marine power and is compatible with LiFePO₄ lithium, AGM, and lead-acid batteries, smart alternators, and Euro 6 charging systems. Furthermore, the built-in Emergency Start Assist feature provides a temporary 60-second override that reconnects your auxiliary battery to help crank your big motor without jumper cables. Whether you run a big offshore center console or a modest bass boat, the Sea Clear Power BPR Battery Paralleling Relay is an accessory you shouldn't leave the dock without.
