Can a Vapcell 26650 5500mah (red) fit in a FT03 sst40?

I’ve heard people recommend the Vapcell and the Shockli 5500mah for the ft03, but its dimensions seem aweful close. Can someone confirm they use these batteries in a ft03? Thanks.

That's exactly what I have in a few of my FT-03's and they fit with a little room to spare.

Awesome I was worried as far as the numbers on paper and only ordered one. Thanks!

most batteries should fit, except protected ones but u dont want to use those anyways.

Yes, I use this exact battery in this exact light. No problem.

I have the FT03 and, I’m using a Samsung 30T.My question is, would I be better off with a 26650 battery instead?

Shoccli or Vapecell?

Well according to the vendor, your FT03 only demands ~ 11A max. You could get longer runtime from a 26650 5500mAh 20A cell.

overkill yes, that battery is for lights that draws alot of amps, this light doesnt so i would get a 5000mah 26650 instead for longer runtimes.
