With the capability to manage up to three battery banks simultaneously, this versatile charger ensures your marine adventures are powered efficiently and safely, no matter where you sail.

Advanced Battery Management

The ChargeMaster Plus integrates multiple essential functions into a single device, eliminating the need for separate auxiliary chargers, battery isolators, and Voltage Sensitive Relays (VSR). This consolidation not only reduces system complexity but also lowers overall costs, making it an indispensable addition to any marine electrical setup.

Battery’s Best Friend Technology

Equipped with the Battery’s Best Friend architecture, the ChargeMaster Plus caters to a wide range of battery chemistries, sizes, and voltages. Utilizing a fast and safe 3-step+ charge method, it ensures optimal battery health and longevity. Key features include:

• Revival Mode: Automatically revives even fully depleted batteries, bringing them back to life quickly.
• Priority Charge: Directs available power to the lowest battery, ensuring faster and more efficient charging.
• Smart Input: Allows all three batteries to be charged from a single alternator, providing continuous charging while on the move.

Global Charging Compatibility

The ChargeMaster Plus is engineered to handle worldwide AC voltages and frequencies, making it ideal for international marine applications. Its robust design withstands large voltage fluctuations and high temperatures, ensuring reliable performance in even the harshest marine environments. Certified for marine and mobile use, it meets CE, ABYC, UL, SAE, CEC, and RCM/C-Tick standards.

Effortless Installation and Monitoring

Designed with user convenience in mind, the ChargeMaster Plus features an intuitive LED display that clearly shows the charging phase for all three outputs. Robust and ergonomic connections facilitate quick and easy installation, saving valuable time on board. The integrated VSR eliminates the need for additional components, ensuring that the alternator’s energy is efficiently directed to the batteries.
