Voltage Sensing Relay Kit, Intelligent Self Switching Split Charge Relay Kit 12V / 30Amp

This voltage sensing, self switching split charge relay is used for charging a second battery from your main vehicle (crank) battery. This relay is different from other standard split charge relays in that it does not require an alternator connection or an ingition switching point - it just connects between the main & auxilliary batteries. No over charging can take place and also does not interfere with the normal charging that takes place between your main battery from the alternator and wont leave you with a flat.

Safety First!

The most important part of a circuit is the FUSE! So make sure you install them with the kit. We supply 2 auto fuse holders & 2 auto fuses with our kits.... Why? Double the protection! We protect our kits on both sides of the Self Switching relay. The 1st fuse point is installed a few inches away from the main battery positive and the second fuse point is installed a few inches away from the leisure battery positive. This give you double the protection in the event of a short circuit.

Suitable for any 12V negative earth vehicle, where a second battery needs to be charged

Example of use: If you install a second battery in your vehicle for running additional appliances and need it to be charged from your vehicles existing system. The relay kit is connected between the vehicles main battery (Positive) and the second battery (Positive).
