Removable vape batteries power some of the best mod setups on the market, and choosing the right cell makes a real difference to your vape. The most common sizes are 18650 and 21700, with 20700 cells also available for certain devices. Each format has different capacity (mAh) and continuous discharge ratings (CDR), so matching the right battery to your mod matters for both performance and safety. At Legion of Vapers, we stock cells from Fogstar, Vapcell and Molicel, brands that experienced vapers and independent testers actually rate. Browse the range, and enjoy 5% off your first order plus free UK delivery on orders over £40.These are the cells vapers come back to buy again and again, because getting the right one is what keeps a mod running at its best.

We stock vape batteries because we use them. Fogstar, Vapcell and Molicel are the brands we trust in our own mods, and the Molicel P42A in particular is one of the most widely respected 21700 cells among independent battery testers. That is the standard we hold our stock to.

Free UK delivery applies on orders over £40. If you want to go deeper on safe use and handling, our vape battery safety guide covers everything from wrap checks to storage and disposal.
If you run a dual-battery mod, your two cells should be treated as a matched pair rather than two separate batteries. This is often called marrying your batteries, and it matters for both performance and safety. Always use the same pair together in the same mod, charge them together on the same charger cycle, and rotate them together as they age rather than treating one as a spare. Never mix an old, worn cell with a new one, since mismatched capacity or discharge can cause one battery to work harder than the other. Keeping cells married is essential for dual-battery devices, helping them wear evenly and reducing the risk of imbalance-related issues.
