Details

Built for 1S Tinywhoop builds, each 3.8V 550mAh LiHV pack uses a BT2.0 plug and a 100C discharge rating in a compact 68×16×8.5mm form factor.

A full 550mAh cell helps maintain consistent punch and runtime compared with under-capacity packs.

The set includes four 1S 550mAh LiHV batteries plus brand stickers and a user manual for setup and care.


A stacking-cell build is intended to support longer cycle life and efficient power delivery for demanding 1S flights.
