BT2.0 Connector - the most significant revolution in 1S Tiny Whoop Drone.
Betafpv exclusive designed BT2.0 connector 1S battery has finally come out, which has broken through the bottle-neck of PH2.0 crappy crimped pins. Meanwhile, we provide 200 sets of BT2.0 300mah 1S battery(2pcs) and a certain number of BT2.0 connectors as a free gift for everybody. Click here to grab BT2.0 battery / connector.
Bullet Point
- BT2.0 connector decreased internal resistance of connector effectively by upgrading the crimped pins to 1.0mm banana connector and increasing the cross-sectional area of 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 disturbance of low voltage warning.
- Compared with the PH2.0 crimped pins, BT2.0 connector is more durable which can discharge more currents in the same capacity and provide far more power. You can get 2mins flight time in full throttle on Meteor65.
- The package comes with BT2.0-PH2.0 adapter cable in the package, which is convenient to charge BT2.0 battery with stock PH2.0 charger. Meanwhile, we also release BT2.0 all-in-one battery Tester & charger for your need.
SPECIFICATION
- Item: 1S battery
- Capacity: 300mAh
- Rate: 30C/60C

BT2.0 Connector
There is a graph of comparison between BT2.0 connector and PH2.0 connector (solid pins version) in BETAFPV 1S 300mAh battery. The discharge current is 9A in this testing. You could see that it has double time ( about 2minutes) and a 0.2v improvement in voltage sag with BT2.0 connector.

BetaFPV knows some of pilots might have a question about how to deal with the old PH2.0 1S battery. So they provide some accessories like BT2.0 Power whoop connectors for those people who wanna convert the PH2.0 connector to BT2.0 connector. Much more choices and more convenient in installation.
- BT2.0 Connectors (10pcs)
- BT2.0 1S Whoop Cable Pigtail
- BT2.0-PH2.0 Adapter Cable
- BT2.0 Battery Charger and Voltage Tester
- BT2.0 Connector 1S Lipo Charger Board

Difference between BT2.0 battery and PH2.0 battery
As we can see, the BT2.0 300mah 1S battery is adopted with the 1.0mm banana connector while the PH2.0 battery is the crimped pins. Also, it is a bit longer than the original PH2.0 battery, which is marked BT2.0 on the label.

BT2.0 Connector - the most significant revolution in 1S Tiny Whoop Drone.
Since February 2019, BetaFPV got some feedback on Facebook about how eager they need the high quality of BT2.0 connector on 1S whoop drone. So BetaFPV started their long-term investigation on the design of the 1.0mm banana connector and the stable manufacturing technique to meet pilots' demand. Betafpv always keeps moving forward with passion for breakthrough experiences.
BULLET POINTS
- BT2.0 connector decreased internal resistance of connector effectively by upgrading the crimped pins to banana connector and increasing the cross-sectional area of banana connector.
- With these connectors, it can support 9A continuous current and 15A burst, while the PH2.0 connector supports 4.5A continuous current.
- 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 disturbance of low voltage warning.
- Compared with the PH2.0 crimped pins, BT2.0 connector is more durable which can discharge more currents in the same capacity and provide far more power. You can get 2mins flight time in full throttle on Meteor65 if you use our BT2.0 300mah 1S Battery.

BT2.0 Connector
BETAFPV exclusive designed BT2.0 connector has broken through the bottle-neck of PH2.0 connector. BT2.0 connector decreased internal resistance of connector effectively to allow more current that is transferred, which means it supports 9A continuous current(15A burst) 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.
There is a graph of comparison between BT2.0 connector and PH2.0 connector (solid pins version) in BETAFPV 1S 300mAh battery. The discharge current is 9A in this testing. You could see that it has double time (about 2minutes) with BT2.0 connector.
