This advanced 72V 4A Lead Acid Battery Charger. Designed specifically to cater to the demanding needs of modern electric vehicles, this charger utilizes an intelligent 3-stage charging mechanism (Constant Current, Constant Voltage, and Floating/Trickle Charge). This ensures your battery is topped up quickly while actively protecting it from degradation.

Constructed with high-grade electronic components and a robust heat-dissipating shell, it delivers a stable 4-amp output that significantly reduces charging time compared to standard alternative chargers. Whether you are powering up an e-bike, electric scooter, or a custom mobility vehicle, this charger provides the safety, speed, and reliability you need to keep moving.

Features

• Intelligent 3-Stage Charging: Automatically switches between constant current, constant voltage, and trickle charge to maximize battery lifespan.

• Auto Shut-Off Technology: Built-in smart circuitry detects a full charge and cuts off power to prevent overcharging and overheating.
• Advanced Protection Suite: Equipped with short-circuit, over-current, over-voltage, and reverse polarity protection.
• Efficient Heat Dissipation: Features an internal cooling fan and ventilation slots to maintain an optimal operating temperature.
• LED Status Indicator: Dual-color LED light clearly displays the charging status (Red for charging, Green for fully charged/standby).

Applications

• High-power electric bicycles (E-bikes)

• 72V electric scooters and mopeds
• Electric rickshaws (E-rickshaws) and loaders
• Golf carts and utility mobility vehicles
• Custom industrial 72V lead-acid battery banks

Usage

• Ensure the electric vehicle or battery bank power switch is turned off.

• Connect the charger’s DC output plug into the vehicle’s charging port securely.
• Plug the AC power cord into a standard wall outlet and switch the mains turn on.
• Verify the LED light turns Red, indicating that the fast-charging process has begun.
• Once the LED light turns Green, the battery is fully charged. Disconnect the AC plug first, then the DC plug.

Maintenance

• Keep the charger in a dry, well-ventilated area away from direct sunlight and moisture.

• Regularly clean the cooling fan vents with a dry cloth or soft brush to prevent dust build-up.
• Avoid dropping or subjecting the charger to heavy physical impacts.
• Do not cover the charger with cloth, plastic, or any insulating material while it is in operation.
