Overview
The 2S Whoop Cable Pigtail (BT2.0) is a dual-connector power pigtail designed for 2S whoop drones such as Beta65X HD and Beta65X FPV. It uses BT2.0 connectors to help reduce voltage sag and improve discharge efficiency for 1S LiPo batteries used on 1S brushless whoop drones.
Key Features
- Specialized for 2S whoop drones (e.g., Beta65X HD / Beta65X FPV).
- 22AWG lightweight customized wire; US standard core 0.08 mm x 60.
- Silicone outer layer diameter: 1.5 mm (stated as 0.2 mm thinner than standard 22AWG wire).
- BT2.0 connector design reduces internal resistance by upgrading crimped pins to a 1.0 mm banana connector and increasing its cross-sectional area.
- Current ratings stated for BT2.0: 9A continuous, 15A burst; PH2.0 stated as 4.5A continuous.
- Polarity color code: Blue = positive (+), White = negative (-).

Details

The 2S Whoop Cable uses dual BT2.0 connectors and lightweight silicone wire for compact whoop builds.

A short lead length helps keep wiring tidy in tight 2S whoop frames.


A discharge comparison illustrates the reduced voltage sag associated with BT2.0 versus PH2.0 under load.

BT2.0 accessories make it easy to standardize batteries, charging, and adapters across a whoop setup.
