CHARGE ON THE GO 12V VSR

The 12V Trolling Motor Voltage Sensitive Relay (VSR) allows the outboard engine charging system to charge the 12V trolling motor battery when underway. When the engine is started, and the engine battery reaches 13.7V, the VSR engages, paralleling the trolling motor battery with the engine battery, for a combined charge. The batteries will remain paralleled until the engine is turned off, and the voltage between the batteries drops to 12.8V. At this stage, the VSR disengages the batteries, isolating the engine battery from the trolling motor battery. The Trolling Motor VSR is rated for engine charging systems up to 125A. Not recommended for engines with alternator charge output of less than 20A. Includes 2 - 3' battery cables (red & black).
