How to use

Connect the charger to the AC mains using the appropriate country mains lead, then plug the 5.5×2.1 mm DC connector into the compatible socket on the e-bike battery or its external charging port. Ensure the battery nominal voltage falls within the 36–42 V range before beginning charge. Monitor the battery and charger during initial use to confirm correct connection and charging behavior. After the battery reaches the manufacturer-recommended charge level, disconnect the charger first from the battery and then from the mains.

Recommendations

Use the charger only with batteries rated for 36–42 V and compatible with a 5.5×2.1 mm DC input. Avoid exposing the charger to moisture, extreme temperatures, or direct sunlight during operation. For longest battery life, follow the battery manufacturer's charging instructions and avoid prolonged storage at full charge.
