Mastervolt recently unveiled 36V and 48V Mac Plus DC-DC chargers. They have bi-directional technology for a quick, safe and consistent charge on service and starter batteries.

“Charging service batteries of a vehicle or vessel can be challenging due to voltage drops and insufficient charging,” Eric Lindquist, vice president and general manager, power systems at Navico Group, stated in a press release. “The Mac Plus provides consistency and peace of mind to users, providing stable power when they need it most.”

According to Mastervolt, there is no risk of draining the starter battery when charging the house bank because it automatically monitors whether the engine is running or providing charge. The Mac Plus uses the Mastervolt three-step-plus charge algorithm.

The new models can charge two batteries from a single alternator or charger. The batteries can be lithium, and the system functions with modern alternators such as Euro 5 and 6. The Mac Plus is also compatible with CZone, NMEA 2000 and MasterBus.

Parallel configuration is possible for as many as 10 units that will provide over 100 amperes.

Does the Mac Plus need a noisy fan to keep cool? Nope. Mastervolt says the system does not require any use of a fan at all.
