Z-Folding Process

The Z-Folding process is stated to provide low internal resistance for efficient high-current discharge, a 0.2V higher voltage under load compared to wound cells, 5% higher energy density (same volume), and extended cycle life. Cell layer labels shown: anode, separator, cathode.

Whats Included

• 2 x LAVA II 4S 580mAh or 680mAh 95C Battery

Warning

• Please 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 the charging process.
• Always keep the battery away from flammable and explosive 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

Power More. Fly Longer. LAVA II 4S LiHV packs combine higher capacity with a 95C discharge rating in a compact size.

The 580mAh version keeps a short, tidy XT30 lead layout for clean 4S builds where space is limited.

Under a 33A load, the LAVA II 580mAh 95C pack maintains a higher voltage curve than the prior 75C generation.

Z-Folding processed cells are engineered for efficient high-current output, improved thermal control, and longer cycle life.

Each set includes two batteries packaged in the LAVA box, plus the included paperwork.
