BetaFPV LAVA II 3S LiHV Battery 580mAh/680mAh 95C 11.4V XT30 + JST-XH2.54 Balance Plug

Overview

The BetaFPV LAVA II 3S Battery is a LiHV battery designed to deliver higher and more consistent power output, featuring a core material upgrade and Z-Folding processed cells. It is offered in 580mAh and 680mAh capacities with a 95C discharge rate, targeting responsive performance and longer flight time.

Key Features

• Core material upgrade with 5.5%-7.7% more capacity and a 95C discharge rate
• Performance claims: 26.7% increase in discharge rate (95C vs. 75C) and 33.6% current boost
• Z-Folding process: low internal resistance for efficient high-current discharge; 5% higher energy density; extended cycle life
• Voltage stability notes: 0.1V higher and more stable discharge voltage; up to 0.2V higher voltage under load vs. wound cells
• Connectors: XT30 main connector and JST-XH2.54 balance/charge plug

Applications

• Compatible use case listed: Pavo20 Pro II
• Pavo Series and beyond (as referenced)

Warning

• Fully charge the new battery before use.
• Only use a charger designed for lithium polymer/Li-ion battery, and never leave the battery unattended during charging.
• Keep the battery away from flammable materials while charging.
• Never overcharge the battery. The maximum voltage for a LiPo battery is 4.2V per cell, and for a LiHV battery is 4.35V per cell.
• Never discharge the battery to a level below 3V per cell under load.
• Do not store fully charged batteries for more than 3 days. For long-term storage, maintain the voltage between 3.8V and 3.9V.
• Do not disassemble, crush, short circuit, or expose to flame or other sources of ignition.
• Do not use batteries that are deformed or swollen.

Details

Designed for punchy, consistent power delivery, the LAVA II 3S LiHV pack pairs a 95C discharge rate with an XT30 lead for high-current builds.

The 580mAh option keeps the same 3S LiHV voltage in a compact 71×20×15.5mm footprint for tighter frames.

Stepping up to 680mAh adds capacity while maintaining the same slim 20mm width and 15.5mm height.

Discharge testing at 33A illustrates the higher, steadier voltage profile of the 580mAh 95C pack versus a 75C alternative.

A 39A discharge curve highlights how the 680mAh 95C version is tuned for sustained high-current demands.

Z-Folding processed cells are engineered to support efficient high-current discharge with improved energy density and cycle life.

Each set includes two LAVA II 3S LiHV batteries packaged in the LAVA box.
