Overview
BT3.0 connectors are 3-pin connectors designed for 2S batteries and 2S whoop drones. With three metal pins, they provide balancing power during charging without an extra balancer connector, simplifying 2S battery assembly while reducing weight (BT3.0 male + female: 1.28 g per set).
Key Features
- Designed specifically for 2S whoop drone batteries.
- Combines balance charging and discharge power functions in a single connector.
- 3-pin terminal design: two 1.3 mm pins for battery discharge (BATT V+ / BATT V-), plus an additional 1.0 mm pin used for balance charging (S Port).
- Polarity marks on the welding cup; reverse connection is not supported.
- BT3.0 2S Whoop Cable Pigtail uses a 90-degree male connector for easier plugging/unplugging.
- BT3.0 Cable Pigtail wire mapping: blue = positive (+), white = negative (-).
- BT3.0 can serve as a 2S balance charging port and can be used with a conventional 2S balance charger via a BT3.0 male-to-male adapter cable.

Details
BT3.0 connectors combine 2S discharge power and balance charging into a single 3pin plug to simplify whoop battery builds.
The two larger pins carry BATT V+/V for discharge, while the third pin is the S Port for balance charging.
Wire mapping stays straightforward: blue to positive (BATT V+) and white to negative (BATT V).
Use the BT3.0toXH2.54 adapter to connect BT3.0 2S packs to a conventional 2S balance charger.
