Here we have our Voltage Sensitive Relay (VSR) allows two batteries to be charged at the same time. When the engine is started and the start battery reaches 26.6 volts, the VSR engages, allowing two battery banks (start and Auxiliary Batteries) to be charged simultaneously.

When the voltage drops below 25.6 volts (eg the engine is stopped), the VSR disengages, separating the batteries. This system eliminates the possibility of draining the start battery and protects sensitive electronic equipment powered from the Auxiliary Battery from harmful engine start up spikes.

Features: 

Voltage sensitive relay 24 volt 100 amp Red LED indicator.Allows split charging of the 2nd battery bank without discharging the primary/start battery. The relay makes connection at 26.6 volts and breaks at 25.6 volt.

Advantages of fitting a VSR over conventional charge (diode isolators). Easy 3 wire connection at the battery. No need to bypass existing alternator wiring. VSR have no volt drop. Conventional diode isolators incur a minimum of 0.6 volt drop. Compact size - No large heat sink Cost effective solution, Quality product, affordable price.
