Avatar 21700 Battery – 4000 mAh, 30 A
Massive capacity meets high performance: the Avatar 21700 Battery delivers an impressive 4000 mAh of power and a manufacturer-rated 30 A continuous discharge, making it a solid choice for high-wattage vape mods and power-hungry electronics.
Key Features
- 4000 mAh Capacity – One of the highest-energy 21700 cells available for extended usage.
- 30 A Discharge Rating – Designed for high-drain applications; real-world testing estimates optimal performance around 20 A.
- Long Cycle Life – Retains up to 80% capacity after 1000 charge cycles.
- Built-in Safety Chip – Offers overcharge and over-discharge protection for added peace of mind.
- Compact 21700 Format – Fits newer mods and packs, with better energy density than traditional 18650 cells.
Bench-Test Insights
Independent tests showed nearly the full advertised capacity (~3960–4000 mAh), but significant heating occurred when pushed to 30 A—20 A is considered a more sustainable continuous load.
