Mosasaur 58.4V 18A LiFePO4 950W Fast Battery Charger for 48V/51.2V Golf Cart

Wide Compatibility: MOSASAUR 58.4V 18A 950W charger is designed for 48V (51.2V) LiFePO4 batteries. Featuring a sealed structure design and an input voltage range of AC90V-264V, it is also compatible with flooded lead-acid, sealed gel lead-acid, and other 48V lithium batteries. Suitable for cyclic or float charging of battery packs used in electric motorcycles, passenger cars, sightseeing vehicles, patrol cars, forklifts and more. 

Fast Charging – Fast, Safe, and Battery-Friendly: The 48 volt lithium battery charger features a smart 3-stage process that protects your battery and extends its life. First, a gentle low current wakes up over-discharged batteries. Then it switches to 18A fast charging to get your equipment back to work quickly. As the battery nears full, it automatically reduces current for a safe, no-overcharge top-off.. When fully charged, it shuts off by itself – no need to watch over it. Built-in heat protection lowers power when internal temperature exceeds 66°C, and stops at 75°C to prevent damage. Stable, reliable charging, every time.

Safety Protections: Our MOSASAUR 48V charger looks out for you and your battery. If no battery is connected, it quietly shuts off after 20 seconds. Should a short circuit happen, it stops output immediately and only resumes when the fault is cleared and battery voltage is above 10V. The output current stays steady no matter how the grid fluctuates – so you never have to worry about sudden overcurrent. Temperature protection works both ways: when the charger runs too hot, it lowers the current; if the battery ever exceeds 60°C, charging pauses until it cools down. Everything resets automatically when safe. Just plug in and charge with confidence.

LED Indicator: The built-in red and green LED tells you exactly what's happening. Red flashing means charging. Green flashing means battery is between 80% and 100%. Solid green means fully charged. If an issue occurs, the light flashes alternating red and green – alerting you to hardware faults, AC problems, battery disconnection, battery over-temperature, charger over-temperature, or short circuits. No guesswork. Just a quick look and you know the status. 

IP66 Waterproof, Dustproof & Anti-Vibration: MOSASAUR 51.2V golf cart battery charger uses fully encapsulated silicone gel potting, sealing every internal component. This gives you three real benefits: IP66 protection against water, dust, and corrosion; good shock and vibration resistance for bumpy rides; and better heat dissipation for longer life. The 16ft cable adds flexibility – park farther from outlets, keep the charger clear of moving parts – making daily charging simpler and safer. A charger that survives rain, dirt, and hard knocks. 

Wide Temperature Range & Thermal Protection:This 58.4V lithium battery charger operates reliably from -30°C to +65°C (-22°F to 149°F), whether you’re charging in freezing winters or hot summer engine compartments. It also features smart thermal derating: when internal temperature exceeds 66°C, the current automatically decreases by 3.2A for every 1°C rise (minimum 4A). If temperature reaches 75°C, the charger safely stops output to prevent damage. No sudden shutdowns – just intelligent protection that keeps your charging going as conditions allow.

Reliability Tests: MOSASAUR 48V 18A charger has passed multiple reliability tests. Insulation resistance over 50MΩ. Withstood 1500V high voltage between input/output and the case – no breakdown. Endured 8-hour full-load aging at 40°C, plus 8-hour tests at low (90V) and high (264V) input voltage. It also passed official vibration tests (10-55Hz, up to 0.75mm amplitude) and drop tests. No damage, no performance loss. Whether mounted on a golf cart or a forklift, you can count on it to handle the bumps and heat of daily work.
