Meet Lava II: compact 1S LiHV power for micro quads

Designed for popular 1S tiny whoops, the Lava II 320mAh LiHV battery balances light weight with a high‑discharge profile. Each cell contributes to quick bursts and crisp throttle response without adding unnecessary bulk, helping you stay nimble in tight spaces. Weighing about 8.2 g and measuring 64 × 10 × 6 mm, this pack minimizes drag while delivering reliable power across your flights. The BT2.0 connector keeps swaps fast and simple for compatible builds like Air65, Meteor65 Pro, and Cetus kits.

In this 5‑pack, you get five compact packs ready to fuel your micro drones. The combination of a compact form factor, robust discharge, and a proven BT2.0 interface makes these cells a practical choice for daily flying and casual freestyle sessions alike.

What makes Lava II stand out

• Leap in performance: 95C discharge rate supports snappier throttle response and steadier bursts, with a potential current boost in practice that helps you feel quicker response in tight maneuvers.
• Increased capacity & efficiency: 320mAh capacity and a max voltage of 4.35V per cell translate to longer flight times and a more stable discharge under load.
• Z‑Folding technology: An advanced folding method yields higher energy density and a longer cycle life compared with conventional wound cells, contributing to more reliable power over time.
• Multi‑adaptability: BT 2.0 connector ensures easy compatibility with a wide range of 1S Tiny Whoop drones such as Air65, Meteor65 Pro, and Cetus for quick, plug‑and‑play swaps.
• Iconic new design & expanded power range: The distinctive green and yellow livery marks the Lava II line, which now includes a fuller range of capacities from 280mAh to 680mAh for tailored performance.

Real‑world use cases

Picture a busy indoor race or an outdoor buzz through a windy street canyon. The low weight helps maintain agility while the high C‑rate supports sudden throttle inputs without compromising control. The BT2.0 compatibility makes it easy to rotate between drones or kits, keeping you in the air with minimal downtime.

With longer run times and a stable voltage under load, you can focus on flight lines, practice rounds, or light filming sessions. The five‑pack format offers ready replacements so you can keep your flights moving without recharging between every run.
