BT2.0 Connector - the most significant revolution in 1S Whoop Drone.
Since February 2019, we've got some feedback on Facebook about how eager they need the high-quality solid pins connector on 1S whoop drone. So we started our long-term investigation on the design of the solid pins and the stable manufacturing technique to meet pilots' demands. BETAFPV always keeps moving forward with a passion for breakthrough experiences.
After BT2.0 300mAh 1S battery, BT2.0 450mAh 1S battery is following close at its heels. As the first 450mAh 1S battery with a BT2.0 connector in the current market, it has an exclusively designed BT2.0 connector, which has broken through the bottle-neck of the PH2.0 crappy crimped pins. What's more, it is highly recommended for Emax Tinyhawk, which achieved dynamic balance, longer flight time, and better performance, just need to simply modify its connector to BT2.0 connector.
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.
