When I said “bad stuff” above I mostly referred to the Yonii Q1's test result, it ended up pretty bad.
Will anyway send a private message to Henrik, or is it Hendrik? Henrik is as I had seen his name before, and the spelling for which a good deal of hits the (G00gl€) forum search makes. Will suggest him to fix the spelling typo.
TS, those sound like worthy mods to accommodate this cell and worth your effort. So far, KawiBoy’s FT03 mod seem the most simple to accomplish and certainly worth while for its other variants. Aloft Hobbies is out of stock on the QB26800 at the moment but is expected to receive more cells in 2-4 weeks.
I cut the bottom off the left side of an Xtar X2 charger so a 26800 now barely fits. Recharged two batteries both drained from a HaikeLite HK4S which has a 2.72 volt cut off. First battery is a Shockli 5500 mah and the second was the QB26800. Shockli charged 5703 mah, QB26800 charged 7124 mah. Both batteries are on their 3rd or 4th recharge.
Thats a great idea for your X2 charger. Those are some nice comparative charging results. Aloft Hobbies is still out of stock on the QB26800. I emailed them again a few days ago to see if and when they plan on re-stalking.
I guess you got lucky. I never received the notification and its not in my spam folder. Oh well… thanks again for posting. I plan to mod my FT03 fleet but not sure I want to hack into my new copper 90.2 version. Also have a 2 x 26650 light with an addition extension tube that could use some additional mAh. Fun stuff!
I just checked my email and already received a shipping notice. :+1:
KB - I'm also interested in more details on the FT03 mod. Looks like you saved a lot of space on the driver side.
I'm thinking, but haven't check measurements, you did this:
reamed out the center of the driver retaining ring to make it thinner so the battery can fit through it (probably can dremel it down)
tossed the original plastic piece around the driver spring
removed the driver spring and replaced with a small flat copper slug (or something like this?)
replaced the tail spring with one that will compress completely flat (dunno where to find one like that, but I could rig of something equivalent I think
Not sure if the first 3 would get the batt as low as you show there in the tube, but it would help. If you used a lathe or something like that to mod the tube or head, I'm screwed.
Update: Ohh, ok. You added bored out copper rings, so you used those for extra spacers, and I see you filled in the gap on the outside with a black o-ring. Think that's the trick...
Why is it that so many 18650 lights have stoopit-long springs but all the 26650 lights I have are contortionist-tight?
I got an old River Rock 2×C light that I tried stuffing in a regular 26650 but it was too tight a fit. Might try “boring” it out a bit with a sander or something, as it’d be worth it to stuff one of these in there and take up the slack later.
