Battery Master

Automatic engine battery charging system
Works even without mains hook-up!

Once installed, Battery Master is completely automatic in operation.
The only maintenance required is an occasional check to ensure that none of the cables are chaffed or being damaged by heat.

When the voltage in your vehicle leisure battery is significantly higher than the engine battery, the Battery Master will allow a controlled transfer of current.
When the transfer is taking place the LED will show RED.
When the voltage in both batteries become approximately equal, Battery Master will cut off the transfer and the LED will change to GREEN.
If the leisure battery is being charged by mains hook-up or solar panels, Battery Master will maintain the engine battery indefinitely even if it is being discharged by an alarm, radio, clock etc.
If the leisure battery is not being charged in any way then Battery Master will allow the engine and leisure batteries to share the discharge load thus greatly increasing the time before the vehicle battery will fail to start.

Installation of the Battery Master could not be easier.
To ensure easy installation the Battery Master has in built thermal fuses and being potted is totally waterproof and immune to vibration damage so can be mounted anywhere.
