Charging & Safety Notes
- Verify charger settings match the battery: 4S LiPo (14.8V nominal) and JST-XHR-5P balance connection.
- Stop charging at 4.2V per cell (typical LiPo range: 3.7V to 4.2V per cell).
- Inspect the pack before each use; discontinue use/charging if the battery is damaged or abnormal.
- If a new battery does not hold a full charge or loses charge rapidly, use a balance charger and cycle it several times.
