Built with premium materials, this 21700 cell offers significantly higher energy density than traditional 18650 batteries, packaging 4000mAh of robust capacity into a compact form factor. While the battery includes a manufacturer warning against use in unregulated devices, it is incredibly safe and reliable when utilized in the smart, regulated vaporizers and mods available at ZVaporizer Australia. The durable outer wrap protects the cell from external damage, ensuring long-term safety and resilience.

How to Use & Maintenance
