Charging & Safety Notes
- Only use when the voltage and plug match the model’s requirements.
- Stop charging immediately if any cell reaches 4.2V. Normal cell voltage is between 3.7V~4.2V.
- Check the battery surface condition and verify voltage is normal before first use.
- If a new battery does not hold a full charge or loses charge quickly, use a balance charger and cycle several times.
