Specifications

Battery Mate

Mastervolt’s BI battery isolators are based on conventional diode technology. The diode voltage drop (ca. 0.6 V) can

be compensated for by adapting the output voltage of the connected charger or alternator. Mastervolt Mass battery

chargers and Alpha Pro charge regulators are standardly equipped with automatic voltage drop compensation.

While BI battery isolators are conventional diode splitters, the Battery Mate’s technology is

electronic and includes mosfets (transistors). Its components compensate for the voltage drop

and ensure that charging continues at the right voltage level, even with several battery banks. The

Battery Mate is compatible with any type of alternator/battery charger, in both existing and new

systems. As the voltage loss between the alternator and battery is negligible, the Battery Mate

performs far better than conventional battery isolators. This ensures fast and complete charging

of your batteries without having to make additional adjustments to the alternator.
