Many on-board installations have two or more batteries, which - separately - supply 12V, 24V and/or 48V consumers. This requires a division of the charging system with reliable charging current distributors or battery couplers. Mastervolt has a number of clever solutions for this:



Charging current distributors that distribute your charging current with minimal energy loss
The Charge Mate for connecting and/or disconnecting two batteries
Battery Watch for monitoring the optimal condition of your batteries (can also be used as a main switch if desired)The Mastervolt BI charging current isolators are based on conventional diode technology. The voltage drop across the diode (approx. 0.6V) can be compensated by adjusting the output voltage of the connected battery charger or alternator. Mastervolt battery chargers and Alpha Pro MB charge regulators also have automatic voltage drop compensation as standard.Compact and lightweightThe Mastervolt BI charging current isolators are compact and 'solid state' and will therefore not show any wear. The weight varies from 580 to 1300 grams. Robust and durableFully corrosion-resistant material with aluminium cooling profile. The electronics are encapsulated in plastic, the BI models have encapsulated separating diodes. Quick installation Equipped with plastic end pieces with mounting lip. The solid bolt connections with nut and lock guarantee easy installation.
