Keep your leisure battery fully charged with our split charge relay kit!

This comes with all parts required to enable you to charge up your camper vans leisure battery using the starter battery/alternator of your vehicle. Included in the kit is a voltage sensitive relay (VSR) that only draws power and charges your leisure battery when your starter battery is at a certain voltage. This ensures that you never end up with a flat battery in your vehicle... which is always handy.

This kit has the added benefit of dual isolation, allowing you to isolate the vehicles starter battery and your leisure battery independently. Included in the kit is also a 6 way 12V fuse box, which then allows you to take up to 6 safe and fused outputs from your leisure battery to wire up your 12V accessories.

Please note, VSR’s are only compatible with vehicles without a smart alternator, regenerative braking, or stop/start technology. If you're unsure please just drop us a message.

Excellent, friendly service.

I found Seaside Campers on a Google search when I was looking for suggestions on how to add electrics to my van.
I emailed them looking for advice and guidance before submitting my purchase. I found them very helpful, with a wee bit of banter in their communication. I'm very happy with the quality of my purchase and service they provided

Thank you Robert, we are glad you are happy with your purchase!
