WARRANTY. If the leisure battery is being charged by mains hook-up or a suitable solar panel,
Battery Master will maintain the engine battery indefinitely. This will be true even if the battery is
being discharged by a security system, tracking system, clock and stereo equipment. If the
leisure battery is not being charged, the Battery Master will allow the engine and the leisure
batteries to ‘share’ the discharge. This in turn will allow a greater period of time to elapse before
the boat/motorhome fails to start. Battery Master WILL NOT WORK where the discharge is
GREATER THAN ONE AMP, or where AN ELECTRICAL PROBLEM EXISTS or there is a BATTERY
FAULT OR BATTERY FAILURE on the vehicle/vessel Sunshine Solar are not responsible for any
situation that occurs due to vehicle/vessel failure or any situation that occurs because the
vehicle/vessel fails to start. Battery Master will also now work correctly if it is not installed
properly in these instances no cost whatsoever will be repaid. Where there is a warranty query
the Battery Master should be returned postage paid to the address shown below and must carry
a company issued returns number and a completed Returns Form.

Installation Guide

So often there is a surplus of battery power in your leisure battery, and this
“surplus” goes to waste. With all today's onboard electrical sophistication its not
surprising that many people fear flat batteries and being stranded, unable to start
the engine. Battery Master will help alleviate those worries. Put simply, whenever
there is a surplus of power in the leisure battery, Battery Master will take the
excess and safely top up the engine battery irrespective of whether the excess is
the result of your solar charger, a built in mains charger or even the natural
discharge of the engine battery over a period of time. Battery Master will never
allow power from your battery to flow into your leisure battery.
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
chaffing or being damaged by heat.
When the voltage in your vehicle/vessel leisure battery is significantly higher than
the engine battery the Battery Master will allow a controlled transfer of current.
When this transfer of current is taking place the LED will show RED. When the
voltage in both batteries becomes approximately equal Battery Master will cut of
the transfer and the LED will change to GREEN.
