Mastervolt ChargeMaster Plus 12/35-3 Charger

Description

The Mastervolt ChargeMaster Plus 12/35-3 is a three-output battery charger designed for boats that need fast charging, global AC compatibility, and system-level monitoring. Mastervolt’s 3-Step+ charging technology manages battery recovery and maintenance automatically and is suitable for a broad range of battery types, including lithium-ion systems and deeply discharged batteries.

Auto-ranging AC input allows the charger to operate from common shore-power supplies around the world without manual voltage switching. The illuminated front display shows charging current, charging voltage, charge phase, battery condition, and MasterBus communication status, giving the user a clear picture of what the charger and batteries are doing. A memory function helps prevent overcharging when the incoming AC supply is unreliable, and cos phi 1 regulation makes better use of limited generator capacity.

The charger can manage multiple battery banks at the same time and can also function as a DC power supply even when batteries are not connected, allowing onboard loads such as lighting or refrigeration to remain powered. MasterBus integration supports central, local, or remote monitoring and control with compatible Mastervolt components. Solid metal-to-metal connections with strain relief help resist corrosion and overheating in demanding installations. Find more in our 3-bank battery chargers.
