The BT2.0 connector has effectively reduced the internal resistance of the connector by upgrading the crimped pins to 1.0mm banana plugs and increasing the cross-sectional area of the 1.0mm banana plug. The BT2.0 300mAh 1S 30C battery supports a continuous current of 9A and a burst current of 15A, while the PH2.0 connector supports a continuous current of 4.5A. With this BT2.0 300mAh 1S battery, all brushless 1S drones achieve strong and perfect performance. By addressing the issue of voltage drop, the discharge of the 300mAh 1S BT2.0 Lipo becomes more efficient. Pilots can enjoy more flight time without the disruption of low voltage warnings. Compared to the crimped PH2.0 pins, the BT2.0 connector is more durable and can discharge more current at the same capacity, delivering significantly more power. You can achieve a flight time of 2 minutes at full throttle with the Meteor65.
