BetaFPV 550 mAh Battery for Cetus X and Cetus Pro — an original BT2.0 battery from BetaFPV, specifically designed for 75-80mm 1S whoop drones. This battery combines increased capacity and high power, ensuring stable motor operation and extended flight time for Meteor and Cetus series models.
Description and Advantages
The BT2.0 550 mAh 1S battery is intended for pilots seeking longer airtime and reliable power. A continuous discharge rating of 40C and a burst discharge rating of 80C guarantee powerful and stable discharge under load. Thanks to its high current reserve, the battery reduces the likelihood of voltage sag during intense maneuvers, allowing brushless motors to operate more predictably and efficiently. An ideal choice for both daily training and micro-drone competitions.
Suitable For
- 1S BetaFPV whoop drones: Meteor75, Meteor75 HD, Meteor75 Pro, Meteor75 Pro HD, Cetus Pro, Cetus X;
- other 75-80mm micro-drones using the Betafpv BT2.0 connector;
- pilots who want to replace a 450 mAh BT2.0 with a higher-capacity battery for increased flight time.
