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 Euro 5 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.
