4-piece BT2.0 550mAh 1S drone battery set
For every FPV whoop drone enthusiast looking to maximize flight time and improve the dynamics of their machine, the BetaFPV 550mAh BT2.0 battery is an ideal choice. Specifically designed for 1S brushless drones, especially for larger 75–80 mm models, it utilizes the proven BT2.0 connector technology. The increased 550mAh capacity, combined with outstanding voltage stability, ensures that the drone flies longer, stronger, and more predictably, providing even more enjoyment during every flight.
BT2.0 connector – no more voltage sag
The key to the outstanding performance of the 550mAh battery is the design of the BT2.0 connector. Compared to traditional PH2.0 connectors, the BT2.0 significantly reduces internal resistance by using larger cross-section, 1.0 mm contacts. This solution effectively eliminates the phenomenon of "voltage sag," which often causes premature low voltage warnings and performance drops under load. As a result, the BT2.0 550mAh 1S battery provides:
- Stable power supply: consistent performance even during intense maneuvers.
- Longer actual flight time: fewer early low voltage warnings.
- Greater dynamics and faster response: more precise control and better maneuverability.
- Increased connector lifespan: more robust design for longer use.
Optimized for 1S whoop drones
The BT2.0 550mAh 1S battery is designed for demanding pilots. It boasts an impressive 40C continuous and 80C burst discharge rate, providing powerful and stable energy supply. It fits perfectly with popular BETAFPV models that use the BT2.0 450mAh battery, offering better balance and longer flight time. An ideal choice for the following models:
- Meteor75, Meteor75 HD, Meteor75 Pro, Meteor75 Pro HD
- Cetus Pro
- Cetus X (by connecting two 1S batteries in series)
