High-Power 84V 3A Charger for 72V Li-ion Batteries with Smart Features and Cooling Fan

The AFU battery charger features a three-stage intelligent charging mode to ensure your battery is fully charged. The first stage is constant current, followed by constant voltage, and finally a trickle charge. This charging process is designed to optimize battery performance and lifespan.

The charger's sturdy aluminum case is built to withstand compressive deformation, offering durability and protection for long-lasting use. Two LED indicators provide clear charging status - red for charging, green for fully charged. This allows you to easily monitor the charging progress without guesswork.

To enhance cooling and extend the charger's service life, a built-in high-power cooling fan effectively reduces operating temperatures during use. The charger can operate in a wide range of ambient temperatures, from -20°C to +40°C, and can be stored in temperatures from -40°C to +70°C.

For safety, the charger is equipped with multiple protection features, including overcurrent, overvoltage, overtemperature, short circuit, reverse polarity, and anti-back charge protection. These safeguards help prevent damage to both the charger and your battery.

The AFU battery charger is compatible with 20S 72V Li-ion batteries, making it suitable for a variety of applications. It accepts 100-120VAC, 50-60Hz input and provides 84VDC, 3A output. The package includes the charger, a US standard power cable, an operating manual, and two replaceable fuses.
