Charge and maintain your large-capacity batteries with the professional-grade SUOER Four-Phase Smart Battery Charger. This high-amperage 50A unit is specifically designed for 12V lead-acid and gel batteries, providing an automated, multi-stage charging process that maximizes battery life and ensures a full, safe charge every time.
Built with a durable aluminum chassis and advanced cooling, this charger is ideal for automotive shops, marine applications, and off-grid solar backup systems.
Advanced Four-Phase Charging: Utilizes a sophisticated 4-stage intelligent charging protocol (Pre-charge, Constant Current, Constant Voltage, and Float) to protect battery chemistry.
High-Power 50A Output: Delivers a substantial 50A current, capable of rapidly charging high-capacity batteries used in trucks, boats, and heavy machinery.
Integrated Ammeter & Monitoring: Features a clear analog display for real-time monitoring of the charging current, allowing you to track the progress at a glance.
Adjustable Current Control: Equipped with a manual adjustment knob to fine-tune the output current based on the specific requirements of your battery size.
Active Thermal Management: Includes a built-in high-speed cooling fan and a deep-finned aluminum heat sink housing to prevent overheating during extended high-current sessions.
Model: MA-1250A.
Battery Compatibility: 12V Lead-Acid / Gel Batteries.
Output Current: 50A Max.
Charging Phases: 4-Stage Intelligent.
Safety Protections: Reverse polarity protection, short circuit protection, and over-temperature cutoff.
Heavy-Duty Automotive: Charging batteries for commercial trucks, buses, and construction equipment.
Marine & Leisure: Ideal for maintaining deep-cycle house batteries on boats or large RV setups.
Energy Storage: Useful for charging battery banks in off-grid solar systems or emergency backup power stations.
Can I charge a standard car battery with this 50A unit? While this unit can charge car batteries, 50A is a very high current. You should use the adjustment knob to lower the amperage to a safe level (typically 1/10th of the battery's Ah rating) to avoid damaging smaller batteries.
Does it stop charging automatically when the battery is full? Yes. The four-phase smart logic automatically transitions into a float/maintenance mode once the battery reaches full capacity, preventing overcharging.
Is it safe if I accidentally swap the red and black clips? Yes, the SUOER MA-series features reverse polarity protection to prevent internal damage or sparks if the connections are accidentally reversed.
