Mastervolt ChargeMaster Plus 24/20-3 Battery Charger – 24V, 20A, 3 Outputs

The Mastervolt ChargeMaster Plus 24/20-3 is a 24 V, 20 A battery charger built for fast, complete charging wherever you are. Its 3-Step+ charging process helps your batteries perform better and last longer, and it also charges deeply depleted batteries. It suits recreational and semi-professional use and works with any battery type, including Lithium-Ion.

Charges Anywhere in the World

Auto-ranging input accepts 90–265 V AC at 50 or 60 Hz, so the charger runs fully automatically on any mains supply. Cos phi 1 regulation gets the most out of limited generator capacity. A built-in memory function helps prevent overcharging when mains power is unreliable.

Three Charge Outputs

Charge up to three battery banks at the same time, such as a service battery and starter batteries. Each output delivers up to 20 A, for a total charge current of 20 A at 28.8 V. It supports battery banks from 40 to 200 Ah.

Clear LED Display and MasterBus Connectivity

A lit LED display shows charge current, charge voltage, charge phase and battery status, along with MasterBus communication. Three buttons make operation simple. MasterBus connects with a single cable, so you can monitor, configure and control your system centrally, locally or remotely alongside other Mastervolt products.

Built to Last

Solid metal-to-metal connectors with strain relief resist corrosion and overheating. Standard safety features protect your batteries and your system. Installation is quick and straightforward.

Built-In DC Power Supply Mode

Even with no battery connected, the charger provides a constant DC output to run lights or keep a fridge cold.
