12V 30 Amp Voltage Sensing Relay For Camper Van / Motorhome Split Charge System
About this item
This little device is essential for anyone building out a camper van or caravan.
It's a 12V, 30-amp voltage sensing relay (VSR) for your split charge system.
Basically, it automatically connects your leisure battery to your starter battery when it senses the alternator is charging (like when the engine's running), and disconnects them when the voltage drops to protect your starter battery.
It's a simple, smart way to keep your lights, fridge, and gadgets powered up at camp without draining your vehicle's battery.
Made in the UK, this unbranded relay is a straightforward, reliable component for any DIY campervan electrical setup.
