3. Configuración e instalación
Conexión de la batería
Before connecting the battery pack to your device, ensure the device is powered off.
- Carefully align the XH2.54/3p connector of the battery pack with the corresponding port on your device.
- Gently push the connector into place until it is secure.
- Crucial Safety Tip: Compare the polarity of this new battery pack with your device's original battery or wiring diagram. The standard configuration is Red for Positive (+), Black for Negative (-), and Yellow (or White) for NTC.
Adjusting Connector Wiring (If Necessary)
If the polarity of the new battery's connector does not match your device's requirements, you may need to swap the wire positions within the connector. Proceed with caution and refer to the image below.
- Identify the wire(s) that need to be repositioned.
- Using a small, sharp object (like a jeweler's screwdriver or a pin), gently press down on the metal barb inside the connector housing, adjacent to the wire you wish to remove.
- While holding the barb down, carefully pull the wire out of the connector.
- Once removed, gently repair or lift the metal barb slightly if it was flattened too much, to ensure it will lock into place when reinserted.
- Reinsert the wire into the correct position in the connector until you hear or feel a click, indicating the barb has engaged.
- Repeat for any other wires that need repositioning.
- After re-wiring, double-check the polarity before connecting to your device.
