⚙️ Fit Notes
- Please verify your original battery part number before ordering.
- Match the voltage, connector type, polarity, and battery pack configuration with your original battery.
- This battery uses a 2-pin brown connector that replaces the discontinued black connector.
- Battery replacement should be performed carefully to avoid memory loss or parameter loss in the controller.
