The Mastervolt ChargeMaster Plus 24/40-3 is an advanced multi-output battery charger designed to simplify and secure your onboard power system. By integrating the functions of auxiliary chargers, VSRs, and battery isolators into one device, it reduces installation time and system complexity.

Its unique multi-voltage capability allows it to charge a 24V service bank and a 12V starter battery simultaneously, without the need for an external DC-DC converter. This makes it ideal for marine, automotive and off-grid installations with mixed-voltage setups.

With Battery’s Best Friend™ architecture, the ChargeMaster Plus automatically recognises battery chemistry and condition. It charges Lithium Ion, Gel and AGM batteries using Mastervolt’s proven 3-step+ charging method, ensuring fast, full and safe charging every time.

Key features:

• Multi-voltage design: charges 24V and 12V batteries at once.
• Three outputs: two dedicated and one combined in/out with DC-DC converter and VSR.
• Suitable for Lithium Ion, Gel and AGM batteries.
• Revival mode restores fully discharged batteries.
• Priority Charge for the lowest battery first.
