High amperage switching is achieved with the relay mounted next to the batteries and controlled either manually by a switch on the remote battery switch or by the remote switch mounted in an accessible location. Read the TECH Tip, Solenoid vs Remote Battery Switch RBS Explained on page 35. The installed cost of a remote battery compared to manual battery switch may not be that different. The cost savings from eliminating long runs of expensive large gauge battery cables and replacing them with light gauge control wires can often offset the cost of a remote battery switch.

The advanced Lithium Ion Batteries have a built in Battery Management System (BMS) with active cell balancing. The ML-RBS is utilized for its rapid ability to disconnect the batteries under full load. At any time the Mastervolt BMS can trigger the ML-RBS to safely disconnect the batteries. Once the system is restored the ML-RBS can be re-connected for quick operation. The latching operation of the ML-RBS means that no amperage is consumed during an open or closed state, which further prolongs the available power in the Lithium Ion Batteries. The override knob allows the ML-RBS to be manually disconnected for safe servicing of the battery system. With a rating of 500A continuous, the ML-RBS pairs perfectly with all of the Mastervolt Lithium Ion Batteries. ML-Series Remote Battery Switch 7700 7702 Class T Fuse Block House Loads
