Thats odd
I use a d4 with my 21700's without issue - they fit and charge fine.
Donated the D4 to a friend and have upgraded to the Xtar VC8 this week.
The i4 may not fit them though - i know the i8 definitely doesnt.
thanks i will check it out
hi there can you recall how tight the fit was. i tried to fit them but i got to pull the spring right down, it feels like iam forcing it
It's not insanely tight. But yes you have to pill the spring all the way down (I usually pull the spring half way, insert the battery, then continue pushing the spring (with the negative side of the batterry).
May also depend how thick your wraps are. Mines were standard ijoy and Samsung wraps.
I fit 2 x 21700 and 2 x 20700 in the D4 without issues.
ok ... i tried again now and followed as you suggested it does actually fit but where i stopped before on the positive side it has to be pressed down and like clipped in or down and that made me hesitant, but i got two charging now .. that clipping/pressing down by the positive lip makes me nervious
I haven't had any issues as yet.
Over a year and a half of charging 20 and 21 sized batteries in the D4. Same batteries still in use today with same original wraps even
Tesiyi takes 21700.
Don't know about a 4-bay I have a two bay that rocks!
I8 does take 21700s, just not wiggle room.

Exactly this. No wiggle room and batteries go flying if you aren’t careful.Eish seemed way too tight a fit for me so I didn't change it.
Actually I tried it and one battery went flying off the spring load lol. Had a very dented battery resulting
