BETAFPV Lava II 680mAh 1S LiHV Battery 95C BT2.0 — 4-Pack for Air75 & Meteor75 Pro

Overview

The Lava II 680mAh 1S LiHV battery from BETAFPV is built to elevate micro quad performance. Designed for popular 1S Tiny Whoops like the Air75 and Meteor75 Pro, it combines a compact form with a high 95C discharge capability and a BT2.0 connector for effortless swaps on the fly.

With LAVA II, you may notice quicker throttle response and steadier bursts during climbs and quick maneuvers, thanks to an upgraded core and energy focus. The pack also emphasizes efficiency, delivering more usable capacity within the same footprint so you can enjoy longer flights without a dramatic increase in size or weight.

Key advantages

• Rapid power delivery with a 95C discharge rate for snappy responsiveness.
• Improved energy density: more capacity in the same 80×15×6.5 mm package.
• Higher voltage under load: 0.2V boost helps maintain performance during bursts.
• BT2.0 connector for broad compatibility with leading 1S Tiny Whoop drones.
• Distinct green-yellow design shows up clearly on the field, with a scalable lineup from 280mAh to 680mAh.

Performance, design, and compatibility

In practice, pilots may experience consistent power delivery across quick hops and tight tracks, with more predictable motor response due to the stable discharge behavior. The Z-Folding approach contributes to energy density gains and a robust cycle life, empowering reliable bursts when you need them most. The battery’s BT2.0 connector aids a smooth plug-and-play experience across compatible quads like Air75 and Meteor75 Pro, reducing setup friction.

The Lava II line expands your power options without changing your airframe, offering a reliable upgrade path from smaller capacities to the new 680mAh option for longer sessions or more aggressive flights.
