CHARGE ON THE GO 12V DUAL SENSE VSR

This system allows for dual battery charging using a battery selector switch. The dual sense VSR will allow the selected battery to be charged to 13.7V then close and charge the battery in isolation. When the engine is stopped and the voltage on the selected battery drops to 12.8V the relay opens and isolates the two banks. A simple battery management system and a great space saver for small boats. 2-3/4"L x 5-1/2"W x 3"D.
