Dual Battery Kits and Parts


Dual battery setups are common in environments where there is a specific battery used for vehicle starting and another separate battery (or battery bank) for powering on board appliances and accessories. This setup is very common in caravans, campervans, marine or high-end show cars with large sound systems or custom lighting.

There are many components to a dual battery setup which can vary depending on power consumption, vehicle type and of course budget. Essentially the dual battery components manage the power coming in. Prioritising power to the main battery and managing automatic low voltage switching during use. This is designed to eliminate the possibility of the critical starting battery running flat!

Mr Positive carries a wide range of dual battery components and full kits. From simple single component relays to complex LCD screen based multi input battery management systems.
