Split Charge Relay

Intelligent Voltage Sensitive Split Charge Relay, for use with campers, caravans, motorhomes, horseboxes and any commercial vehicle requiring a leisure battery.

The term "split charge relay" means that its used to charge 2 batteries whilst driving. Once the starter battery is charged to 13.7v the relay switches over to charge the leisure battery. If the starter battery falls to 12.8v the relay switches back over to charge it back up, continually switching between the 2 as the voltage goes up and down.
