ChargeMaster PLUS is the next generation of battery chargers that integrates multiple functions into one single device.
ChargeMaster Plus features the new "Battery's Best Friend" architecture, which allows it to charge a multitude of battery chemistries, sizes and voltages with the safe and fast 3-step+ charging method. For faster charging, Priority Charge redirects power to the weakest battery, Revival mode automatically brings even fully depleted batteries back to life, and the Pre-Float function (charge retention) eliminates the risk of overcharging smaller batteries.
The charging profile for MASTERVOLT MLI lithium-ion batteries is also included, and it is possible to create a customised, user-defined profile for lithium batteries from other manufacturers, for example, via an optional USB interface and the MasterAdjust software*.

ChargeMaster Plus can handle all possible mains voltages and frequencies worldwide. The battery chargers can resist large voltage fluctuations and high temperatures, making them suitable for the harshest environments - perfect for use on boats and in cars. ChargeMaster PLUS units comply with CE, E-mark, ABYC, UL, SAE, CEC and RCM/C-Tick standards.
ChargeMaster PLUS chargers are self-explanatory! They display the charging phase of all three outputs in an easy to understand way. Robust and ergonomic connections save installation time.
In modern applications, all components work hand in hand. The CAN-based MasterBus allows the charger to communicate with displays, shunts and power systems, including communication standards such as CZone, NMEA and CANopen. The ChargeMaster PLUS can operate as a power supply for sensitive communication equipment or during the construction phase of a boat.
MasterBus, CZone and NMEA 2000 communication interfaces
