The VSR (Voltage Sensing Relay) allows charging of two independent battery banks from a single charging source. When the voltage on the start battery rises to a charged level, the VSR engages allowing the 2nd battery to charge. When charging stops and voltage falls, the VSR will disengage, isolating the two batteries from each other. Dual sensing functionality enables the sensing of two battery banks, allowing two way charging.
