Tiny Whoop 1S 270mAh HV Battery - BT2.0 Connector - V2.0

The 270 just got lighter.

I'm proud to announce that this batch of the TW270 features a custom battery cap (first released in November 2025), which saves a lot of weight! This is the lightest 270 BT2 pack on the planet. ENJOY!!!

 These are the top of the line 270mah batteries for Tiny Whoop aircraft. They're the newest generation of folded-cell 1S packs, delivering a higher discharge rate compared to previous Tiny Whoop packs, and they feature a BT2.0 connector. They are the highest quality 270mAh packs available anywhere, period. The smaller, lighter battery is perfect for freestyle, UTT courses like Racegow, and some races.

Some pilots are here to make sure they get at least 2-3 mins of racecourse flight time, while others are here purely for the

THRILL OF FLIGHT

The future if Tiny Whoop flight is lighter and more agile. The current trend is to make aircraft lighter and lighter, and when you shave just a little weight, your power-to-weight ratio goes up FAST. Compared to the 300mAh packs, these babies will shave OVER A GRAM off your final weight (maybe as much as 1.5g), creating a lot more power for any aircraft. You'll feel more powerful rockets on your back, all for the cost of losing somewhere between 15 and 30 seconds of flight time with most motors meant for 65mm aircraft. 

The latest batch is the lightest so far, with an ULTRALIGHT custom Tiny Whoop Cap bringing the weight down to an average of 6.78138g, including the removeable sticker. HOWEVER - if you remove the two tiny stickers (which together weigh an average of 0.0402333333333 grams), you'll bring the average weight of these packs all the way down to 

And you'll LOVE how 6.760947g feels!!

More significant than the substantial weight loss is the much-improved weight distribution. Keeping the mass of weight closer to the center of gravity means that aircraft can more easily change attitude, particularly pitch attitude. This translates to a more natural feel in flight, not just a lighter feel.
