Voltage Sensitive Split Charge Relays

Voltage sensitive relays (also known as split charge relays) for isolating and charging auxiliary batteries.

PLEASE NOTE: These relays are NOT suitable for vehicles with 'smart' or 'intelligent' alternators that are controlled by the ECU. As a guide this applies to vehicles having engines that comply with Euro5 emissions standards and onward, often also incorporating regenerative braking (if in doubt please consult your vehicle manufacturer to confirm). If your vehicle has a smart alternator then you will need to use a battery-to-battery charger instead of a VSR.
