BT2.0 450mAh 1S 30C Battery (4PCS)


Optimize your drone’s performance with the BETAFPV BT2.0 450mAh 1S 30C battery, tailored for extended flight times and robust power delivery in micro drones. This high-capacity, single-cell LiPo battery features a 30C discharge rate, providing high power output and consistent performance necessary for optimal flying experiences. The innovative BT2.0 connector reduces internal resistance and supports higher currents than traditional connectors, which significantly improves the high-thrust output and prevents voltage drops. Packaged in a set of four, these batteries are perfect for pilots looking to extend their flight sessions with reliable and efficient power sources.

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


Note: BT2.0 450mAh 1S 30C Battery is upgraded and optimized to a battery length 1.7mm longer and a battery port shell width 1mm narrower than the previous one. It is normal to use if the battery cell is visible. Because the battery sticker does not fully cover it. We will change the new battery sticker as soon as possible.


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


Since February 2019, we’ve got some feedback on Facebook about how eager they need the high-quality of solid pins connector on the 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 the BT2.0 300mAh 1S battery, the 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 a BT2.0 connector.




  • BT2.0 connector decreased the internal resistance of the connector effectively by upgrading the crimped pins to 1.0mm banana connector and increasing the cross-sectional area of the 1.0 mm banana connector.
  • By solving the problem of voltage sag, the discharge of the 450mAh 1S BT2.0 lipo becomes more efficient. Pilots can enjoy more flight time without the disturbance of low voltage warnings.
  • BT2.0 450mAh 1S 30C Battery has stable current/voltage output and high efficiency. All 1S brushless drones will gain powerful and perfect performance with this BT2.0 450mAh 1S battery.
  • It is perfectly suitable for Emax Tinyhawk, it can provide stable and consistent power, which achieves dynamic balance and longer flight time. Just need to simply modify the PH2.0 connector to the BT2.0 connector.
  • Compared with the PH2.0 crimped pins, the BT2.0 connector is more durable which can discharge more currents in the same capacity and provide far more power.
  • High-end technology to guarantee high quality and consistent performance.
  • We released the BT2.0-PH2.0 adapter cable, which is convenient for charging the BT2.0 battery with a stock PH2.0 charger. Meanwhile, we also release the BT2.0 all-in-one battery Tester & charger for your needs.



  • Item: 1S battery
  • Capacity: 450mAh
  • Rate: 30C/60C
  • Voltage: 4.35V
  • Dimension: 61*15*7.5mm
  • Connector: Betafpv BT2.0 connector
  • Weight: 12.7g(1pcs)


There is a graph of comparison between the BT2.0 connector 1S 450mAh battery and the Emax 1S 450mAh battery. The discharge current is 11A in this testing. You can see that it has a much longer time and improvement in voltage sag with BT2.0 connector, which brings better flight performance.

Much more choices of BT2.0 series accessories.  

We know some pilots might have a question about how to deal with the old PH2.0 1S battery. So we provide some accessories like BT2.0 Power whoop connectors for those people who wanna convert the PH2.0 connector to BT2.0 connector.
