BT2.0 Connector for Stronger 1S Power
The BT2.0 connector is designed to improve power delivery for 1S FPV drones by reducing voltage sag and increasing conductivity. Compared to traditional PH2.0 plugs, it maintains a more stable voltage output throughout the flight.
Smoother throttle response and better control. More stable voltage under load. Improved overall flight efficiency.

Higher Current Output for Maximum Performance
With support for 9A continuous and 15A burst current, the BT2.0 300mAh battery delivers nearly double the power of PH2.0 connectors. This allows your drone to perform at its full potential without power limitations.
Stronger punch-outs and faster acceleration. More responsive flight performance, ideal for racing and freestyle Tiny Whoop drones
Difference between BT2.0 battery and PH2.0 battery:
As we can see, the BT2.0 300mah 1S battery is adopted with the 1.0mm banana connector while the PH2.0 battery is the crimped pins. Also, it is a bit longer than the original PH2.0 battery, which is marked BT2.0 on the label.
Reduced Voltage Sag for Longer Flight Time
By lowering internal resistance with its upgraded 1.0mm banana connector design, the BT2.0 battery improves discharge efficiency and reduces energy loss during flight. Fewer low-voltage warnings, more usable battery capacity, up to 2 minutes full-throttle flight time (Meteor65 test) The discharge current is 9A in this testing. You could see that it has double time ( about 2minutes) and a 0.2v improvement in voltage sag with BT2.0 connector.

BT2.0 is a game changer compared to PH2.0. Much less voltage sag. Getting a solid 3-4 mins of flight on my Meteor65. This 8-pack is a great deal, well packed.

Good consistent output for whoops, easy to plug in and use. Flight time is short if you fly aggressively, but still reliable for daily indoor use.

I’m new to FPV and everyone told me to get BT2.0. Glad I did. This 8-pack is a great value. Arrived earlier than expected and my flight times are much more consistent now compared to the old PH2.0 connectors.
