Shop for the latest & greatest Fogstar Products from Legion Of Vapers.
Fogstar is a UK-based battery brand with a reputation built on quality cells and consistent performance. In the vaping world, they’re best known for producing high-drain lithium batteries designed for use in regulated and mechanical mods. Through our own testing, we’ve found vapers choose Fogstar because the cells hold their capacity well over time, deliver stable output at high wattage, and come with the build quality you’d expect from a brand that supplies the broader UK battery market.
The range covers 18650 and 21700 cell formats, making Fogstar a practical choice whether you’re running a compact single-cell pod mod or a dual-battery regulated box mod pushing serious wattage. Legion of Vapers stocks a full, authentic range of Fogstar batteries sourced through authorised UK distributors only, so you’re getting genuine cells every time.
If you’re buying batteries for your mod, Fogstar is one of the names we trust ourselves.
We stock Fogstar’s full range of vape-relevant batteries and accessories in one place, so you can find the right cell for your mod without having to shop around.
Fogstar’s vape cells are available in 18650 and 21700 formats, covering a wide range of mod types. The 18650 cells are well-suited to everyday regulated mods and lower-wattage setups, while the 21700 cells offer higher capacity and CDR figures for dual-battery mods running 80W and above. Both formats are built to consistent tolerances, which matters when pairing cells in dual-battery configurations. Getting that consistency right reduces the risk of uneven drain and extends the working life of both cells.
A good battery is only as reliable as the charger and storage you pair it with. Alongside Fogstar cells, we stock compatible accessories including quality multi-bay chargers, battery cases for safe transport and storage, and replacement wraps for cells that have picked up damage. These aren’t optional extras. Correct storage and charging is a basic safety requirement for any lithium vape cell, and cutting corners here is how accidents happen.
We’ve tested a lot of battery brands over the years, and Fogstar consistently delivers what mod users actually need: accurate specs, reliable output, and cells that don’t drop off sharply after a few charge cycles. Running a Fogstar 21700 through a week of high-wattage vaping on a dual-battery mod, we didn’t see the kind of voltage sag you get from cheaper, spec-padded alternatives. The output stays stable in a way that matters day to day.
If you’re running a mod that demands reliable, high-drain power, Fogstar cells are a straightforward, sensible pick. They won’t let you down mid-session.
The right Fogstar cell depends on your mod format, your typical wattage output, and whether you’re running single or dual batteries. Here’s a quick breakdown.
Running a compact regulated mod or a pod system that takes a single 18650, a Fogstar 18650 cell is a solid, low-fuss choice. You don’t need the highest CDR on the market for lower-wattage use. Focus on capacity (mAh) for longer battery life between charges, and pair it with a decent single-bay charger. Simple setup, reliable results.
Running a dual-battery box mod at 80W or above puts real demand on your cells. This is where Fogstar’s 21700 cells earn their place. Higher CDR ratings mean the cell handles sustained high-drain use without voltage sag dropping your output mid-vape. Always use matched pairs in dual-battery mods – two cells from the same batch with near-identical charge levels.

Every Fogstar battery we sell comes through authorised UK distributors only. We don’t stock grey-market imports, and we don’t sell rewrapped cells. Battery authenticity matters more in vaping than almost any other product category, and we take that seriously. Counterfeit and rewrapped cells are a genuine risk in this market, and buying from us removes that risk entirely.
We price Fogstar batteries competitively and regularly run multi-buy deals so stocking up costs less. Check our batteries category for current offers alongside the full range.
Orders are dispatched quickly from the UK, with free delivery available above the qualifying order threshold. No long waits, no international shipping delays.
Our team are everyday vapers who have personally used the gear we sell, batteries included. We know the difference between a 30A and a 20A CDR cell, and we can point you towards the right choice for your specific mod and wattage. If you’re unsure which Fogstar cell suits your setup, get in touch and we’ll give you a straight answer.
Fogstar has earned its standing in the UK battery market through consistent cell quality and honest specification data. Their vape batteries use high-grade lithium-ion chemistry rated to real-world continuous discharge figures, not inflated marketing numbers. That distinction matters more than most vapers realise when they’re choosing cells for a high-wattage mod.
Fogstar’s transparency around cell specifications, rather than relying on padded marketing claims, is what sets them apart from less reputable battery suppliers. When a brand publishes honest CDR data rather than chasing impressive-looking numbers, that’s a good sign you’re dealing with a serious manufacturer.
