What type of battery is this?

It is a 1S LiHV (high voltage) LiPo battery designed for Tiny Whoop and micro FPV drones.

What is the capacity and voltage?

It has a capacity of 450mAh and a nominal voltage of 3.8V (4.35V when fully charged).

What connector does it use?

It uses the BT2.0 connector, which offers lower resistance and better efficiency than PH2.0.

What drones is it compatible with?

Compatible with most 1S Tiny Whoop drones using BT2.0 connectors, such as BETAFPV Cetus and Meteor series.

What is the discharge rate?

Rated at 30C continuous discharge (up to 60C burst).

How much does each battery weigh?

Each battery weighs approximately 12.7g.

Does BT2.0 really improve performance?

Yes, it reduces voltage sag and improves power delivery, resulting in longer flight time and better throttle response.

Can I use it with PH2.0 drones?

Yes, but you will need a BT2.0 to PH2.0 adapter or modify the connector.

Is it suitable for beginners?

Yes, it provides stable power and is widely used in beginner-friendly Tiny Whoop setups.

How long is the flight time?

Flight time depends on the drone and flying style, typically around 3–5 minutes for Whoop drones.

Can I use higher capacity batteries like 550mAh?

Yes, but higher capacity increases weight, which may reduce agility despite longer flight time.

What charger is required?

A LiHV-compatible charger with BT2.0 connector or adapter is required.

Yes, when used and charged properly following LiPo safety guidelines.

What’s included in the package?

4 × 450mAh 1S BT2.0 batteries.

Bullet Point

● BT2.0 connector decreased internal resistance of 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 450mAh 1S BT2.0 lipo becomes more efficient. Pilots can enjoy more flight time without disturbance of low voltage warning.

● BT2.0 450mAh 1S 30C Battery has stable current/voltage output and high efficiency. All 1S brushless drones will gain powerful and perfect performance with this BT2.0 450mAh 1S battery.

● It is perfectly suitable for Emax Tinyhawk, it can provide stable and consistent power, which achieved dynamic balance and longer flight time. Just need to simply modify the PH2.0 connector to the BT2.0 connector.

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

● High-end technology to guarantee high quality and consistent performance.

● We released the BT2.0-PH2.0 adapter cable, which is convenient to charge BT2.0 battery with a stock PH2.0 charger. Meanwhile, we also release BT2.0 all-in-one battery Tester & charger for your need.
