Fit and forget solution to flat batteries - to see you through those long winter months or any other extended period when the van is not used. Allows vital chassis components (immobilisers, clocks, radio memories, security systems etc) to 'share' the load with the leisure batteries.

Will allow charging to the engine batteries On-Off mains hook-up. When solar panels are fitted it gives all the batteries (chassis or engine) installed into the motorhome a 'solar charge'.

BATTERY MASTER will never allow power to be taken from the engine battery to the leisure battery. Fully waterproof, British Made and Designed easy to install, comes complete with fitting kit and instructions.

Question:          Will Battery Master work with a solar panel?
Answer:             Yes, most certainly. It could have been made for it. As the solar panel increases the voltage in the leisure battery, so the excess charge is stored away in the engine battery.

Question:          Will it work the other way and flatten the engine battery?
Answer:             An emphatic NO. Battery Master will only take power from the leisure battery, never the other way around.

Question:          Will it work without mains hook-up?
Answer:             Yes.  It is designed that when the engine battery drops half a volt below the leisure battery, Battery Master automatically adjusts the charge and tops up the engine battery.

Question:          Does this mean that I could leave my van for longer in the winter without the fear of a flat engine battery?
Answer:             Yes.
 

Question:          Is it easy to fit?
Answer:             Anyone who understands basic 12 volt circuitry can fit it. For those who prefer to have it installed, the set fee for installation is £30.00
