42V 4A Charger for Electric Bike and Electric Scooter

Input: The charger has an input of AC 100-240V 50/60Hz and an output of 42V 4A. The LED display indicates red when charging and green when charged. It can be used in temperatures ranging from -10°C to 50°C, with a humidity level of 20%-90%. For storage, the charger can withstand temperatures from -10°C to 60°C, with a humidity level of 20%-90%. The charger's DC Plus measures 5.5 x 2.1 x 1.1mm. The package includes a 42V 4A battery charger and a power cord.

Use and maintenance of the charger: 1. When charging, connect the battery first, then connect to AC. After charging is complete, unplug from AC and then remove the battery plug. Pulling the battery plug first can damage the charger, especially when the charging current is high (indicated by a red light). 2. When the LED turns green, continue charging for an additional 2-3 hours. 3. Do not allow the battery to run out completely before charging, as this can damage the battery. 4. For long-term shallow discharge batteries, perform a deep discharge every 3 months for activation. 5. If the battery has not been used for 2-3 months, charge it before use. 6. Use the charger in a dry place. 7. Do not leave the charger connected to the power supply when not in use. 8. Ensure the charger is compatible with your lithium battery and avoid using it with LiFepo4 batteries to prevent overheating.
