Set of 8 BT2.0 300mAh 1S Drone Batteries For any FPV enthusiast who strives for maximum performance and longer flight times for their miniature drones, the BetaFPV Cetus 1S 300mAh BT2.0 Battery is a real game-changer. Designed for models like the BetaFPV Cetus, Meteor65 and Meteor65HD, this battery is the key to unlocking your machine's full potential. Its heart is the BT2.0 connector, which is the most significant revolution in powering 1S drones, effectively solving problems known from older solutions and offering much better voltage stability and higher power. No more Voltage Drops: BT2.0 Technology in Action The BT2.0 connector significantly exceeds standard PH2.0 connectors thanks to its well-thought-out design. The improved terminal pins have been replaced with solid 1.0 mm connectors with increased cross-sectional area, which drastically reduces internal resistance. In practice, this means that the BT2.0 300 mAh 1S 30C battery can deliver a continuous current of 9A and a pulse current of 15A - twice as much as the PH2.0 (4.5A continuous current). For the FPV pilot, this translates into specific benefits: More stable voltage: Effectively eliminates the problem of voltage sag under load, ensuring constant power. Longer effective flight time: You can fly longer, without premature low voltage warnings that cut the fun short. Greater power and dynamics: All 1S brushless drones will receive a significant boost in power, which you will feel in improved throttle response and maneuverability. An example is Meteor65, on which you can achieve up to 2 minutes of flight at full throttle. Increased durability: The improved design of the BT2.0 connector is also much more durable, meaning longer and more reliable use. Key Parameters and Compatibility The BT2.0 300mAh 1S battery is designed for an optimal balance between performance and a compact size, ideal for small FPV drones. Here are its detailed parameters: Capacity: 300mAh Configuration: 1S / 4.35V (high voltage, HV) Discharge rate (C-Rate): 30C continuous / 60C momentary (Max Burst discharge Rate) Weight: 8.28g Dimensions: 67.3 x 11.8 x 6.1 mm Connector type: BETAFPV BT2.0 Compatibility: Dedicated to, among others: for BetaFPV Cetus, Meteor65, Meteor65HD and other brushless 1S drones.
