Enerdrive 12V Dual Battery Kit

Enerdrive Dual Battery Kit Featuring; VSR, 3 x battery terminal clamps, battery cable positive & negative along with required accessories.


The Enerdrive Dual Battery Kit allows for safe charging and separation of starting and auxiliary batteries in all 12 Volt Marine, 4WD, Caravan and Solar applications.

When the engine is started, starting and auxiliary batteries are separated allowing only the starting battery to be charged. When the charge voltage reaches 13.3 volts the Voltage Sensitive Relay engages allowing both starting and auxiliary batteries to be charged. This is indicated by the red light in the top LH corner being illuminated.


When the engine is stopped and the battery voltage falls below 12.8 volts the VSR disengages separating the start and auxiliary batteries, at this point the indicator light will be out and the auxiliary battery continues to power any accessories without risk of draining the starting battery.


The Enerdrive VSR also has Dual Sensing which senses the charge of both batteries. If either battery is receiving a charge, e.g. a battery charger is connected to the auxiliary battery; the VSR will engage and charge both batteries.
