Mastervolt Mac Plus DC-DC Converter with MasterBus – Battery-to-battery charger

€589,90 - €700,90
Tax included.

Short trips, long charging times – that's a thing of the past: The Mac Plus from Mastervolt charges your service battery quickly, completely, and gently directly from the starter battery. The intelligent 3-stage charging algorithm precisely adapts to the installed battery type, ensuring maximum lifespan and capacity. Thanks to MasterBus connectivity, the Mac Plus can be seamlessly integrated into your onboard network system.

Tip: When operating multiple Mac Plus units in parallel, charging currents well over 100 A can be achieved – ideal for large service batteries on long-distance yachts or catamarans.
