Category: Drones & Quadcopters > Drone Components > Drone Batteries.
Description and Advantages
BT2.0 batteries from BetaFPV have proven themselves among pilots due to their high performance, voltage stability, and long lifespan. The 550 mAh model sets new standards for 1S whoops: a nominal continuous discharge of 40C and a peak discharge of 80C, which provides a significant power boost and better control dynamics. The improved Betafpv BT2.0 connector minimizes voltage loss and withstands higher currents compared to PH2.0 connectors, which is especially important during aggressive maneuvers and high loads.
- Increased capacity compared to 450 mAh allows for more flight time with minimal weight increase.
- High current characteristics (40C / 80C) ensure stable power to motors and better boost for brushless 1S whoop drones.
- The BT2.0 connector is more resistant to loads, ensuring reliable contact during intense flights.
- Compact size and low weight help maintain the balance of small quadcopters and do not overload the model's chassis.
Compatibility
The battery is compatible with models: Meteor75, Meteor75 HD, Meteor75 Pro, Meteor75 Pro HD, Cetus Pro, and Cetus X. Please note: for Cetus Pro and Cetus X, two 1S batteries are used, connected in series, to provide the necessary operating voltage and power reserve for flight and the video system.
