Product description

This kit will stop your leisure battery use draining the main vehicle battery, and allow you to charge your leisure battery from the alternator whilst the engine is running.

The wiring kit for the split charge is made with 16mm² cables, fused to 100A.

The solid-state relay will open, allowing the current to flow between the two batteries, when one of the batteries is charging (above 13.7V) and it will disconnect the two batteries when the voltage drops below 12.8V.

The VSR relay, comes with mounting screws to secure it firmly near the leisure battery.

Professional quality insulated joints throughout the system.  

Only very basic tools required to fit. 

The 6 way 12V fuse box, as an optional extra above will take fuses of up to 10A in each fuse position.

The installer of this system must be competent in working with electricity.
