When charging, first connect the charger to the battery, then plug into AC power. After charging is complete, disconnect from AC power first, then unplug the battery. Do not disconnect the battery while charging, especially when the charging current is high (red light), as this may damage the charger. 2. When the LED light turns green, continue charging for an additional 2–3 hours. 3. Do not fully discharge the battery before recharging. Charging after complete discharge may result in reduced battery protection or potential damage. 4. For batteries used with frequent shallow discharges, perform a deep discharge approximately every 3 months. This process, known as reconditioning, helps activate inactive materials within the battery. Deep discharge is achieved by riding until the controller’s low-voltage protection activates. 5. Always use the charger in a dry environment. 6. When not in use, disconnect the charger from the power supply. 7. Confirm compatibility with your battery type. This charger is designed specifically for lithium batteries. Do not use with LiFePO4 batteries, as this may cause the charger to overheat.
