BetaFPV BT3.0 Connector / Wire Set

The BetaFPV BT3.0 connector system is engineered specifically for 2S whoops and micro drones, integrating power delivery and cell balancing into a single streamlined plug. By eliminating the need for a separate balance lead on your batteries, the BT3.0 standard saves critical weight and reduces cable clutter on ultra-light builds like the Pavo Pico.

Key features

• Innovative 3-pin design handles both main discharge and 2S balance charging through one unified connection.
• Sheds unnecessary flight weight by completely removing standard XH2.54 balance wires from the battery pack.
• Solid metal pins reduce internal resistance compared to traditional folded-metal connectors, minimising voltage sag under heavy throttle.
