VSR Battery Charging Kits

Upgrade your camper van electrics with high-quality VSR battery charging kits designed for reliable leisure battery charging and efficient off-grid power management. At Wired Campers, our range of voltage sensitive relay (VSR) split charge kits are built specifically for camper van conversions, motorhomes and van life setups, offering a simple and cost-effective solution to keep your auxiliary battery charged while on the move.

Our VSR battery charging kits, including the popular Wired Campers 3M, 5M and 10M Voltage Sensitive Split Charge Relay Kits, provide everything you need for a complete installation. Each kit features a durable 12V 140A voltage sensitive relay, heavy-duty 16mm² high-flex battery cables, fuse holders, terminals and all essential wiring components, ensuring a professional-grade setup straight out of the box.

Designed for ease of use, these split charge systems automatically detect when your vehicle’s starter battery reaches the correct voltage and safely divert power to charge your leisure battery. This intelligent functionality prevents battery drain and ensures your starter battery remains protected, making it ideal for camper van electrics, off-grid systems and touring setups.

Our kits are suitable for traditional alternator systems commonly found in pre-Euro 6 vehicles. With multiple cable length options available, you can easily tailor your installation to suit SWB, LWB or custom camper layouts.
