SmartCom intelligent caravan relays

Light power voltage sensing relays. Our range of split charge relays for light leisure battery power usage.

If you spend most of your time camping connected to the site mains electricity supply and your leisure battery usage is minimal, then these inexpensive split charging options are ideal for you.
If you tow a caravan then the Ring Smartcom relay is a great way to keep your leisure battery topped-up and your fridge running while on the move. The Smartcom relay doesn't require an alternator connection, you simply wire it from your starter battery to the leisure battery and a separate wire to the fridge if required (either via the 12S towing socket on caravans, or direct to the leisure battery/fridge on campers and motorhomes). Because you don't have to cut into any of the vehicle's wiring, warranty problems on modern vehicles with complicated engine management systems are not an issue. Ideal for vehicles with multiplex and canbus wiring systems
The Ring Smartcom split charge relay is also a superbly inexpensive, easy to fit, split charge option for caravans, campervans and motorhomes.
