NeuBETAFPV BT2.0 550mAh 1S Akku (4 Stück) langlebig für Whoop

Bullet Point

● BT2.0 connector decreased the internal resistance of the connector effectively by upgrading the crimped pins to 1.0mm banana connector and increasing the cross-sectional area of 1.0mm banana connector.

● By solving the problem of voltage sag, the discharge of the 550mAh 1S BT2.0 lipo becomes more efficient. Pilots can enjoy more flight time without the disturbance of low voltage warnings.

● BT2.0 550mAh 1S Battery has stable current/voltage output and high efficiency. All 1S brushless drones will gain powerful and perfect performance with this BT2.0 550mAh 1S battery.

● Compared with the PH2.0 crimped pins, the BT2.0 connector is more durable and can discharge more currents in the same capacity and provide far more power.

● It is perfectly suitable for BETAFPV 1S whoop drones that use the BT2.0 450mAh battery, it can provide stable and consistent power, which achieved dynamic balance and more flight time. For example, Meteor75, Meteor75 HD, Meteor75 Pro, Meteor75 Pro HD, Cetus Pro, and Cetus X (double 1S battery in serial).

BT2.0 Connector = Less Voltage Sag

Upgraded 1.0mm banana connector reduces resistance compared to PH2.0, allowing more current to flow with less voltage drop. 

User value: stronger punch-outs, fewer low voltage warnings

40C Continuous, 80C Burst Power

Delivers higher discharge capability than typical 1S batteries, giving your whoop more punch and better throttle response. 

User value: faster acceleration, more responsive control.

Stable Voltage for Consistent Flight

Optimized discharge performance reduces voltage sag under load, keeping power output smooth throughout the flight.

User value: more usable flight time, smoother flying experience.

550mAh Battery VS 450mAh Battery

BT2.0 550mAh 1S battery was upgraded in capacity and C-rate compared with the BT2.0 450mAh 1S battery. So it can provide more flight time and power for whoop drones that used 450mAh battery. For weight-sensitive whoop drones, BT2.0 450mAh 1S battery is also a good choice.

There is a graph of comparison between BT2.0 1S 550mAh battery and BT2.0 1S 450mAh battery. The discharge current is 13.5A in this testing. You could see that it has a longer time and improvement in voltage, which brings better flight performance.

The below picture shows the discharge of BT2.0 550mAh 1S battery in 22A (40C).

Built for Daily Flying

Durable LiHV cells and improved connector design provide longer lifespan and consistent performance over repeated charge cycles. User value: fewer replacements, more reliable sessions.

Note

The flight time testing for both batteries is based on the 4.35V-3.2V voltage.

Pilots should remove the battery plate if installing this battery on Cetus Pro.
