Battery Distribution Cluster with VSR - Vert 125a (113689)

Twin battery charging made easy!



Pre-assembled module with solid links and application labels combining three 701 Mini Battery
Master Switches with a 100 amp Voltage Sensitive Relay. This system is an ideal replacement
for an existing four position battery selector switch, easily connected to the existing wires,
to provide a fully automatic battery management system. Provides for isolation of
start and house batteries independently with the ability to emergency parallel
supply from both.



The VSR will automatically prioritise the charging of the
start battery. When the engine is first started the relay is open and
remains open until the start battery has reached a preset 13.7 volt.
At the rated voltage, the relay closes providing charge to both
batteries (start and house). When the voltage drops below
12.8 volt (when the engine is stopped), the VSR
disengages, separating the batteries. This system
eliminates the possibility of draining the start battery and
protects electronics powered by the house battery from
harmful engine starting spikes. Available in horizontal,
vertical (designated in the on position) or square
configuration. An optional recessed mounting plate is also
available.
