Z-Folding Process

The Z-Folding process delivers a superior performance advantage, leveraging its low internal resistance to enable efficient high-current discharge and a 0.2V higher voltage under load compared to wound cells, ensuring consistent and robust power. This architecture also achieves a 5% higher energy density within the same volume and a significantly extended cycle life. Furthermore, it provides unparalleled design freedom, allowing for precise customization of the battery's size and shape to meet specific application requirements, offering broader versatility than traditional winding methods.

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. 

Package Includes:

• 5 x BETAFPV LAVA II 1S 320mAh 4.35v HV 95C BT2.0 Battery
