Sterling Pro Batt BBW Battery-to-Battery Charger (Waterproof)

Sterling's new Pro Batt BBW battery-to-battery chargers feature a waterproof aluminum housing (IP68) with an integrated fan.
(IP55, replaceable). This design results in the most powerful and efficient waterproof battery-to-battery chargers Sterling has ever developed.

Thanks to the pre-installed cables (1.5m long) with 8mm ring terminals and a pre-installed fuse, installation is quick and easy. The existing system usually doesn't need to be modified; the B2B chargers (B2B stands for Battery-to-Battery) are simply installed between the primary and secondary batteries. They operate fully automatically: as soon as the primary battery voltage exceeds a predefined value (e.g., 13V), the charger activates and switches off automatically when the voltage falls below that value. Unintentional discharge of the secondary battery is impossible.
