The BT3.0 connectors are designed for the 2S battery, with 3 metal pins that enable balancing power when charging without an extra balancer connector. It simplifies 2S battery assembly and weighs only 1.28 grams, making it smaller and super lightweight than regular connectors on the market. For 2S quad pilots, it also presents a more convenient choice for the 2S battery, as well as the better option for minus some grams off the quad.

Below is the diagram for the male, female connectors.
The BT3.0 connectors are a 3PIN terminal, two metal pins with a diameter of 1.3mm are used for battery discharge, and two metal pins with a diameter of 1.3mm and a metal pin with a diameter of 1.0mm are combined into a 3PIN connector as a balanced charger for battery charging. The BT3.0 connectors have polarity marks on their welding cup but don't support reverse connections. When welding wires, make sure to pay attention to the positive and negative directions. The connector's design prevents reverse connections, so do not force it in the opposite direction to avoid short circuit risks.
This power cable with the BT3.0 connector is specially made for a 2S whoop drone. The male connector and the power cord are at a 90-degree angle, which makes it easy to plug and unplug. The insertion and extraction force range is 3-22N, making daily use more effortless. It fits 2S FC and 2S quadcopter.
When you resolder your board, please pay attention to the connection method. BT3.0 Cable Pigtail is composed of blue wire and white wire. The blue wire is the positive pole(+), and the white wire is the negative pole(-).
The BT3.0 connector can serve as a 2S balance charging port and can be used with a conventional 2S balance charger to charge the battery through a BT3.0 male-to-male adapter cable, providing customers with greater flexibility to choose their own charging method.
