BT2.0 1S Whoop Batteries
BT2.0 1S Whoop Batteries
12 products
BT2.0 is the 1S battery connector BetaFPV introduced for tiny whoops. Its solid 1mm pins carry more current with less voltage sag than the older PH2.0 plug, which you feel as stronger punch at the end of a pack. This page collects every 1S battery with a BT2.0 connector in our range. Match the plug to the pigtail on your whoop, then choose capacity by frame size: small packs for 65mm, larger ones for 75mm and 85mm.
How to choose a BT2.0 battery
- Capacity by size: 280–320mAh for 65mm whoops, 450–480mAh for 75mm, and 550–680mAh for 85mm whoops and 1S toothpicks. A heavier pack flies longer but dulls the handling.
- LiHV: most whoop packs are high-voltage cells that charge to 4.35V. They need a charger with an HV setting to reach full capacity.
- C rating: 75C and 95C packs sag less under throttle. On a 1S whoop the difference shows in the last minute of the flight.
- Pack count: these are sold in sets of two to five. A session usually takes six or more packs, since each lasts three to five minutes.
- Dimensions: check the pack length against your whoop's battery slot, especially for 550mAh and larger.

Compatibility
A BT2.0 battery only plugs into a BT2.0 pigtail. Whoops wired for PH2.0, A30 or BT3.0 need the pigtail changed or an adapter, and adapters add resistance. Charge with a 1S charger that has BT2.0 ports and an HV mode. Store the packs at about 3.8V per cell between sessions; whoop cells left full or empty lose capacity quickly.
Frequently asked questions
- Is BT2.0 better than PH2.0?
- Yes for power delivery. The BT2.0's solid pins have lower resistance than the PH2.0's folded contacts, so voltage sags less under load and the whoop keeps its punch longer.
- Can I use a BT2.0 battery on a PH2.0 whoop?
- Not directly. Either solder a BT2.0 pigtail onto the flight controller or use an adapter. Swapping the pigtail is the better fix, since an adapter gives back some of the resistance you were trying to remove.
- Which capacity for a 65mm whoop?
- 280mAh to 320mAh. Larger packs add weight that a 65mm whoop's motors struggle with; 450mAh and above belong on 75mm and 85mm frames.
