Magnum Smart Battery Combiner (ME-SBC)

In your camper van or motorhome, you have both the engine battery and a house battery bank. You'll want the ability to keep both the engine battery and house batteries well-charged, and also to be able to use the stored energy from each.

The Magnum Smart Battery Combiner (ME-SBC) is an easy-to-use stand alone 25A battery combiner and isolator for 12 and 24 VDC systems. Unlike other combiners/isolators which use diodes, the ME-SBC uses MOSFETs, which are bidirectional electronic switches, and a control circuit that eliminates the significant voltage drop typical of diode-based isolators and provides automatic turn on and off based on adjustable voltage setpoints. Apply a single charging source to the main battery bank and the ME-SBC charges a second battery bank using a portion of the current. With adjustable voltage ranges, including automatic on/off setpoints, the ME-SBC prevents under or over-charging.
