I bought a ES03 from FastTech, but it came with a 18350 battery and not a 20350. Its loose in the flashlight and it doesn’t feel right having the wrong battery in there.
I’ve done a quick search, but can’t find any 20350 batteries with UK shipping. Does anyone know where I can get one?
only ijoy 20350，produced by great power company
we have some 20350 stock
Thanks, but I can’t find them on you store. Do you have a link? Is shipping the the UK not a problem?
Don’t think it is a very common size. If you do find any, check that it actually performs as well as the 18350 you have. They are more common and some good cells exist in 18350 these days.
If it doesn’t fit great, just put an o-ring or two round the battery to make it not rattle.
Wurkkos has some…surely they will ship to UK either via Ali or their main website?

I see the iJoy models all over eBay but I can’t see what you see there in terms of shipping.
I’m not sure what these 20350 cells are like but it’s possible that good 18350 cells may be the same or even better in actual performance and capacity. (for 18350 the Vapcell F14 1400mAh are wonderful for lower current draw, and the Keeppower UH1835P 1200mAh for higher drain…good benchmarks against whatever the 20350 cells can deliver).
If you want to use what you have, maybe some heat shrink would take up the rattle space (normal cheap 2:1 electrical heat shrink tubing, not the thin plastic battery wraps or the thicker 3:1 electrical shrink tubing… the 2:1 should be about right and you could just do a couple of bands rather than the whole length of the cell to reduce insulation).
It came with an 18650, but it feels wrong. It didn’t come with an adapter, so just lose in there. If I don’t find a 20350 I’ll use one of my good 18350 and couple of o-rings.
Showing out of stock. I found an adapter tube so I can use a 20700, but I have similar lights in 21700, so sort of make the purchase pointless. I’ll keep looking.
Initially, the lights were shipped with a 1200 mAh 20350, later with a 1400 mAh battery, which was more reasonable. I was lucky enough to buy two of them, but if they weren’t available, I’d see no reason to buy this little fatty, i.e., a short D4V2 would be preferable imo.
I was looking for one for my WK40 with shorty tube, but they’re hard to come by.
18350s are kinda limiting, so I just went back to my 18650 tube.
Have you asked Wurkkos for a source?
They sell it or at least list it, but they’re not in stock.
Interesting, I can’t see a 20350 listed. May be just my location.
I got my 20350 cells from wurkkos.com. seem to be sold out right now though. Have been for a little while.
To reduce battery rattle, instead of orings I wrap my cells with masking tape until they fit the tube just right. Comes back off easy with no sticky residue left behind.
