The TQ Wire Switched Balance Cable extension enables you to switch between 1S and 2S charging. The cable is inserted between the TQW2620 Complete Charge Cable and the iCharger.
This Switched Balance Cable is plugged into the right side of the balance port.
- When the switch is pushed forward, towards the charger (position I), you are wired for 1S charging.
- When the switch is pushed towards you (position II), you are wired for 2S charging.
You only use the 2mm balance plug (blue) when balance charging a 2S pack (this wire is disconnected internally within the switch when you have the cable set to 1S). |
