Mastervolt's ChargeMaster Plus battery charger has been designed to provide efficient and reliable performance in all conditions. The battery charger offers multiple functions, all from one compact device - in the process, reducing costs, simplifying the system and eliminating the need for additional battery chargers. As the three bank battery charger can withstand high temperatures and significant voltage fluctuations, it's perfect for use n harsh marine or mobile environments.

ChargeMaster Plus will charge any battery chemistry using a 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.

The battery charger can communicate directly with Lithium-ion batteries, MasterShunt or system display for real time adjustments and optimal performance. Furthermore, ChargeMaster Plus battery charger can achieve full functionality within a complete MasterBus or CZone system, or can alternatively be used as a plug and play standalone battery charger.

Key Features:

All three outputs can provide maximum current.
Automatic current distribution - charging current based on the condition of the battery.
Automatic power distribution, maximum charging current possible on each output.
Can be used as a standalone charger, or as part of a complete system.
Compatible with worldwide frequencies and mains voltages.
Improved cooling technology results in very low noise levels.
Each output can individually go into pre-float, which eliminates the risk of overcharging.
