The Mastervolt ChargeMaster Plus 80A 24v Output 120/230V Input is the professional-grade battery charger serious boaters and anglers depend on to keep their vessels powered and ready for extended time on the water. Built for saltwater and freshwater applications alike, this marine-duty charger eliminates the downtime that comes with dead or depleted house batteries, ensuring your navigation electronics, fish finders, and cabin systems stay operational from dawn patrol to sunset anchoring. Whether you're running a center console, cruiser, or catamaran, the dual-voltage input capability means you can charge at the dock whether you're plugged into 120V shore power or 230V European facilities.
The ChargeMaster Plus delivers 80 amps of charging current to 24-volt battery banks, making it one of the fastest shore-powered charging solutions for larger marine systems. Its intelligent microprocessor-controlled technology monitors voltage and temperature in real time, automatically adjusting charge rate to prevent overcharging, battery damage, or thermal runaway—critical features when your battery investment exceeds five figures. The unit supports multiple battery chemistries and incorporates proven Mastervolt reliability, with isolated DC output that safeguards sensitive onboard electronics from voltage spikes. At just 13 pounds, this compact charger mounts easily in engine rooms or lazarette spaces where heat dissipation and accessibility matter.
This charger is ideal for captains operating 24-volt lithium or lead-acid house banks who need shore-based charging speed without compromising system integrity. The 80-amp output handles the simultaneous charging demands of multi-battery setups, auxiliary starting batteries, and thrusters or bow-thruster systems common on larger vessels. Installation requires standard marine electrical practice—30-amp shore power input and appropriate DC breaker protection—but the modular design integrates seamlessly with existing Mastervolt system architectures. For serious anglers and cruisers who treat their boat as a second home, the ChargeMaster Plus represents insurance against dead batteries and unplanned marina layovers.
