• Revolutionary BT2.0 Connector: The most significant upgrade in 1S Whoop Drone technology.
• High-Performance Power: Supports 9A continuous current and 15A burst for powerful flight.
• Extended Flight Time: Solves voltage sag issue for longer, uninterrupted flights.
Since February 2019, we've listened to your feedback on Facebook and designed the BT2.0 connector to meet your demands. It's a game-changer for 1S whoop drones! Check out our 260mAh, 300mAh, and 450mAh 1S BT2.0 packs and all our BetaFPV gear.
Features
- 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 300mAh 1S 30C Battery supports 9A continuous current and 15A burst, while the PH2.0 connector supports 4.5A continuous current. With this BT2.0 300mAh 1S battery, all 1S brushless drones will gain powerful and perfect performance.
- By solving the problem of voltage sag, the discharge of the 300mAh 1S BT2.0 lipo becomes more efficient. Pilots can enjoy more flight time without the disturbance of low voltage warnings.
- Compared with the PH2.0 crimped pins, the BT2.0 connector is more durable and can discharge more currents in the same capacity and provide far more power. You can get a 2mins flight time in full throttle on Meteor65.

BT2.0 Connector
There is a graph of comparison between BT2.0 connector and PH2.0 connector (solid pins version) in BETAFPV 1S 260mAh battery. The discharge current is 9A in this testing. You could see that it has longer discharge time and improvement in voltage sag with BT2.0 connector, which brings better flight performance.
Here is Betafpv Lab video to show you the best way to replace PH2.0 to BT2.0 connectors.
