Charger 54.6V 3A Adapter for 48V Zero 9 Scooter 15ah 13S Lithium Battery Pack

Input: 100-240VAC, 50/60Hz Output: 54.6V 3A Charge Indicator: Charging - Red Light, Full - Green Light Package Includes: 1 pc Battery Charger, 1 pc Power Cord

Use Steps: 1. Choose the correct charger output parameters according to the battery specifications. 2. Correctly connect the charger to the battery to be charged. 3. Plug the charger into the corresponding AC socket. 4. The charger will self-check and identify the battery for a few seconds, then start charging. 5. During charging, the charger indicator light is red and the fan is working. 6. When charging is complete, the charger indicator light turns green, indicating the battery is fully charged. The current output is then completely cut off and the fan stops working. 7. Unplug the AC plug of the charger, disconnect the charger and the battery, and the battery can then be used.

Attention: 1. Keep the charger clean and avoid moisture. 2. Ensure the charger is not damaged in any way. 3. Ensure the AC power and the charged battery are correct. 4. When powered on or the battery is replaced, the product will perform a test that takes about 6 seconds. Do not plug or unplug the battery during this period. 5. Try to avoid replacing the battery with power on. If the self-inspection is completed and the LED indicator is green, you can directly replace the battery. 6. If the product is damaged, foreign or wet, stop using it to avoid the risk of electric shock. 7. The battery to be recharged must have good self-protection functions to avoid dangerous incidents. 8. There is high voltage inside the product, do not disassemble it to avoid consequences.

The charger is a 54.6V 3A Lithium Li-ion Li-poly Charger for 13-Series 48V Electric Bikes. The connector is gx16-3, with pin ① + ③ -. If the external thread pin gx16-3 of the battery is not ① + ③ -, the charger will not work.

The product uses a high-efficiency high-frequency switching power supply for energy conversion and microcomputer intelligent control for charge management. The case is made of high-quality plastic, with a smooth appearance and no impurities, ensuring durability.

The charger has advanced functions such as self-test, battery detection, short-circuit protection, reverse connection protection, battery protection board activation, automatic charging completion, and complete current cut-off to prevent overshoot. It also has a 105°C output capacitor, global applicable AC input voltage, high efficiency, soft starting current, reduced AC input impact, small size, and light weight.

The charger undergoes 100% full load aging testing, has an internal EMI filter, and minimum ripple. The precision current is within ±0.1A, and the voltage tolerance is ±0.1V, with no virtual marking.

The charger has a built-in fan with a strong design and radiating fins surrounding the board, dissipating heat through the shell. Some heat on the shell during charging is normal.

Protections include over-voltage, over-current, short-circuit, over-temperature, reverse connection, and fuse. The CC-CV working mode maximizes the battery's lifespan, and the charger automatically stops when the battery is fully charged.
