Q: Is this BT2.0 550mAh 1S battery compatible with my drone?

A: This battery is designed for 1S micro FPV drones with a BT2.0 connector, especially 75–80mm whoop models. Please make sure your drone supports BT2.0 and has enough battery space before purchase.

Q: What is the difference between the 550mAh and 450mAh versions?

A: The 550mAh battery offers higher capacity and a higher C-rate, providing longer flight times and stronger power output. It is ideal for pilots who want better performance, while the 450mAh version is lighter and more suitable for ultra-light setups.

NewBETAFPV BT2.0 550mAh 1S Battery (4PCS) durable for Whoop

BT2.0 Batteries are well renowned for delivering excellent performance and durability in 1S whoop drones. The BT2.0 550mAh 1S battery achieves even better performance. It is capable of delivering a discharge rate of 40C (continuous) and 80C (burst). Larger capacity and stronger power bring more flight time and robust flight performance to 75-80mm whoop drones.

Description

FAQ

● 550mAh capacity delivers longer flight times compared to standard 1S batteries.

● 40C continuous and 80C burst discharge provide strong and responsive power output.

● Upgraded BT2.0 connector reduces internal resistance for higher efficiency.

● Less voltage sag ensures more stable performance throughout the flight.

● Designed for 1S whoop drones such as 75–80mm micro FPV models.

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).

Capacity	550mAh	450mAh

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).

More Flight Time

BETAFPV Meteor75, Meteor75 HD, Meteor75 Pro, Meteor75 Pro HD, Cetus Pro, and Cetus X are compatible with BT2.0 550mAh 1S battery, ensuring more time to create and less time worrying about the battery level. Pilots who fly 75-80mm whoop drones can also use BT2.0 550mAh battery.

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.
