Ideal for people wishing to run dual battery systems for lighting, appliances and winching equipment, this heavy duty isolator provides isolation for multi-battery systems to allow the auxilliary battery to be drained without affecting the main vehicle systems.
Using a heavy duty sealed contactor, the system can be used for split charging, or as a remote isolator for heavy loads such as winches.
