BETAFPV Lava II 1S 480mAh LiHV Battery — BT2.0, 95C, for Air75 & Cetus

Meet Lava II: compact, high‑performance power for Tiny Whoops

The Lava II 1S 480mAh LiHV battery is engineered for micro drones, offering a compact 61 by 15.5 by 6 mm form factor that weighs 12.6 g. With a max voltage of 4.35V and a storage voltage around 3.85V, these packs are built to deliver steadier voltage under load. The 1.82Wh energy reserve helps pilots extend flight time without adding bulk to the airframe, enabling snappier throttle response when you need it most.

Designed for 1S Tiny Whoop setups, Lava II is compatible with popular quads such as Air75, Meteor75 Pro, Cetus Pro, and Cetus X. The BT2.0 connector keeps plug‑and‑play setup simple, so you can focus on fine‑tuned performance rather than wiring complexity. Each pack is engineered to sustain stable power through dynamic maneuvers, helping you keep momentum during tight sections or rapid climbs.
