Flat top, unprotected Frequently Asked Questions
Is this battery good for my vape mod?
Yes. It is suitable for most regulated vape mods that use removable 18650 batteries. It provides excellent battery life and safe performance up to mid-range wattages. How long does it last?
With 3500mAh capacity, most users get a full day of moderate vaping. Heavy users running 60–70W may need one recharge or a spare. Is 20A continuous discharge enough?
Yes — for regulated mods up to ~70W per cell. If you vape at extremely high wattages or use mechanical mods, consider a 25A–30A cell instead (e.g., Molicel or Sony VTC series). Do I need a special charger?
Yes. Always use an external intelligent charger (Nitecore, Xtar, Efest). Avoid charging 18650 cells through USB-powered mods whenever possible. Safety Instructions Do not use if the battery wrap is damaged.
Never carry loose batteries—use a protective case.
Do not expose to heat, liquids, or metal objects.
Do not overcharge or deep discharge.
Use only in devices with proper battery protection.
Stop using immediately if the cell becomes hot, dented, or unstable. Always follow safe handling practices when using Li-Ion batteries.
