BT2.0 Whoop Cable Pigtail


Enhance your drone’s power system with the BETAFPV BT2.0 1S Whoop Cable Pigtail, designed to provide a more efficient and reliable connection than traditional micro JST 1.25. This upgraded pigtail features the exclusive BT2.0 connector, which significantly reduces connector resistance and sustains a higher current output, improving overall flight performance. The cable is crafted from high-quality, durable materials that ensure a long-lasting and stable connection, crucial for high-performance drone racing. Weighing just 0.93 grams and measuring 55mm in length, this pigtail is perfectly sized for 1S battery setups in micro class drones, making it an essential upgrade for pilots seeking to optimize their drone’s efficiency and reduce power-related issues during flight.

BT2.0 Connector – the most significant revolution in 1S Whoop Drone.


Not sure if it’s worth BT2.0? Check more from Joshua Bardwell‘video- Proof that BT2.0 connector is better than PH 2.0.


BT2.0 1S whoop cable pigtail is an option for you to modify your drone or your 1S FC board which is with the PH2.0 connector. With the 1.0mm banana connectors, it can support 9A continuous current and 15A burst. Makes the best potential of a brushless whoop drone, and displays the perfect performance of your drone with a BT2.0 300mAh 1S battery.



No more folding cables on quads with the use of BT2.0 U Cable Pigtail. Long-term bending and pulling may cause bending and breakage. This cable is reversed in direction, meaning easier plugging and connecting to batteries for whoops. Longer lifespan due to reversed design for less tension on the cable and lighter weight by reducing pigtail length.

Bullet Point

  • With its BT2.0 interface and a 180-degree U-shaped design, bid farewell to the risk of bent or broken wires.
  • The U-shaped structure features a smooth stepped design, making battery insertion and removal more convenient.
  • The U-shaped structure enables shorter power cables, integrated molding, compact dimensions, and reduced weight.
  • BT2.0 connector decreased the internal resistance of the connector effectively by upgrading the crimped pins to a 1.0mm banana connector and increasing the cross-sectional area of the 1.0mm banana connector.
  • BT2.0 connector supports 9A continuous current and 15A burst, while the PH2.0 connector supports 4.5A continuous current. Brings a more perfect flight experience when you fly the 1S brushless whoop drone.
  • Using the BT2.0 connector, can solve the problem of voltage sag, and the discharge of the 1S lipo battery becomes more efficient. Pilots can enjoy more flight time without the disturbance of low voltage warnings.
  • The light and customized 22AWG wire will make the drone more lighter. The wire uses a US standard core 0.08mm*60. The diameter of the silicone outer layer is only 1.5mm, which is 0.2mm thinner than the 22AWG standard wire.

How To Resolder Your Board With BT2.0 Cable


The BT2.0 U Cable Pigtail and the BT2.0 1S Whoop Cable Pigtail are composed of blue wire and white wire. The blue wire is the positive pole(+), and the white wire is the negative pole(-). When you resell your board, please pay attention to the connection method.


Here are the instructions for the BT2.0 U Cable Pigtail.


Here is the instruction for the BT2.0 1S Whoop Cable Pigtail.

Here is the Betafpv Lab video to show you the best way of replacing BT2.0 connectors.


BT2.0 Connector

BETAFPV exclusive designed BT2.0 connector has broken through the bottle-neck of the PH2.0 connector. BT2.0 connector decreases the internal resistance of the connector effectively to allow more current that be transferred, which means it supports 9A continuous current(15A burst) and offers stronger power and longer flight time on 1S brushless drones while PH2.0 just supports 4.5A You can enjoy more flight time without disturb of low voltage warning through solving the problem of voltage sag. For more instructions, click here to reach out.



There is a graph of comparison between BT2.0 connector and PH2.0 connector (solid pins version) in the BETAFPV 1S 300mAh battery. The discharge current is 9A in this testing. You can see that it has double time (about 2 minutes) with a BT2.0 connector.
