Mastervolt ChargeMaster Battery Charger 3-Step+ Method (12V / 35A)

The Mastervolt ChargeMaster Plus battery charger is designed to provide both efficient and reliable performance in all conditions. This generation of battery charger offers multiple functions in one compact device. The ChargeMaster Plus reduces costs and simplifying the system and eliminating the need for additional battery chargers.

The 'Battery's Best Friend' architecture enables the ChargeMaster Plus to charge any battery chemistry using the fast and safe 3-step+ charging method. Different battery sizes can be combined, as the pre-float functionality eliminates the risk of overcharging smaller batteries. The charging profile of the Lithium Ion battery is included, as well as flexibility for a customised, user-defined profile.

Mastervolt 44310355 battery charger is the all-in-one solution for faster and safer charging

Global charging
The ChargeMaster Plus charges almost any combination of two or three batteries quickly and safely and can handle all possible mains voltages and frequencies worldwide.

Plug-and-play battery charger
The new ChargeMaster Plus models can achieve full functionality within a complete MasterBus or CZone system, or can also be used as a convenient plug-and-play standalone battery charger

Optimal performance
The new ChargeMaster Plus can communicate directly with Mastervolt Lithium Ion batteries, MasterShunt or system display for real-time adjustments and optimal performance.

The battery charger can withstand high temperatures and significant voltage fluctuations. That makes this battery charger very suitable for the most harsh, marine, or mobile environments.
