BT2.0 1S Whoop Cable Pigtail is composed of blue wire and white wire.The blue wire is the positive pole(+), the white wire is the negative pole(-).When you resolder your board, please pay attention to the connection method.
Here is Betafpv Lab video to show you the best way of replacing BT2.0 connectors.
BT2.0 Connector
BETAFPV exclusive designed BT2.0 connector has broken through the bottle-neck of PH2.0 connector. BT2.0 connector decreased internal resistance of connector effectively to allow more current that is transferred, which means it supports 9A continuous current(15A burst) offers stronger power and longer flight time on 1S brushless drones while PH2.0 just supports 4.5A You can enjoy more flight time without disturb of low voltage warning through solving the problem of voltage sag.

There is a graph of comparison between BT2.0 connector and PH2.0 connector (solid pins version) in BETAFPV 1S 300mAh battery. The discharge current is 9A in this testing. You could see that it has double time (about 2minutes) with BT2.0 connector.
BT2.0 Series Accessories
We know some pilots might have a question about how to deal with the old PH2.0 1S battery. So we provide some accessories like BT2.0 Power whoop connectors for those people who wanna convert the PH2.0 connector to BT2.0 connector.
Highly recommend the below products with BT2.0 connectors or cables. BETAFPV will collaborate closely with more brand manufacturers in the future, in order to bring better service and experience to customers.
At first I have a relatively low flight time with my Meteor65 Pro. Then I decided to lighten the Pro. I think because the motors (smaller) have a lower current draw the Nitro Nector Golds are really shining. It is at least comparable to a lot of other packs I have. So the capacity is definitely great, just don’t use them in a high current environment and they will work very well.
For tiny whoop racing, I prefer this motor with the hummingbird guts (AIO camera and canopy) on the 65pro frame with 4-blade 35mm props. Close to 20g, phenomenal run time.
Some people at the racetrack (and CIOTTI) call this an "old school" motor.
I usually make my own 180 degree power pigtail, but BETAFPV designed the perfect pigtail for a fair price, had to buy them... I usually don't like BETAFPV BT2.0 pigtail wires, the silicon is high quality, but where you solder the wire right next to the wire is where it always breaks, I don't expect this to change :-(
I would recommend these excellent BT2.0 Cable Pigtails :-))))
