BETAFPV LAVA II 4S 95C LiHV Battery – XT30 (2PCS)

The BETAFPV LAVA II 4S is the highest-voltage option in the LAVA II lineup, built for 4S micro builds that demand the most responsive, high-current power delivery possible. A core material upgrade pushes discharge from 75C to 95C — a 26.7% increase — delivering a 33.6% boost in available current with a more stable, consistent voltage curve throughout the entire pack. The Z-folding cell construction adds 5% higher energy density and extended cycle life over conventional wound cells.

The XT30 connector keeps the package compact and light — the right choice for micro 4S builds where an XT60 would be overkill. Available in two capacities to suit your priorities.

Choose your capacity:

• 580mAh (2-pack) — 55g | XT30 | Lighter option for a more responsive, agile feel
• 680mAh (2-pack) — 64.2g | XT30 | More capacity for extended flight time

• Discharge Rate: 95C
• Voltage: LiHV 15.2V | Max 17.4V | Storage 15.4V
• Connector: XT30 with 18AWG silicone wire
• Balance Plug: JST-XH2.54

Common Questions

What builds is this battery for?
Designed for 4S micro FPV builds using an XT30 connector. 2.5"-3.5" is the sweet spot. Check your frame's recommended battery voltage and connector spec before ordering.

What's the difference between the 580mAh and 680mAh?
About 9g and a bit of extra runtime. The 580mAh keeps weight down for sharper, more responsive handling — the 680mAh is the pick if flight time is the priority.

What's different from the original LAVA 4S?
The LAVA II uses upgraded cell materials for a 95C discharge rate (up from 75C) and 5.5–7.7% more capacity in the same form factor — more punch and longer flights in a direct drop-in upgrade.

What voltage should I store these at?
Store at 3.85V per cell (15.4V total). Don't leave them fully charged for more than a few days.
