Mastervolt ChargeMaster Plus 24/20-3 Battery Charger 24V 20A 3-Output – Smart Multi-Bank Marine Charger
The Mastervolt ChargeMaster Plus 24/20-3 is a compact and intelligent 3-output battery charger designed for professional marine, RV, and industrial systems. With a total output of 20 A at 28.5 V, it delivers fast, reliable charging to up to three battery banks, automatically adjusting power distribution based on battery condition. Compatible with all major battery types—including Lithium Ion—the charger supports both plug-and-play and fully networked operation with MasterBus, CZone, and NMEA2000 protocols.
The ChargeMaster Plus line features pre-float logic to prevent overcharging of smaller banks, built-in temperature and DC voltage compensation, and a universal input for global use. Its rugged construction, vario fan cooling, and wide operating temperature range make it ideal for mobile or marine deployments in extreme conditions.
