My Convoy S12 and M21B from Banggood arrived yesterday. Both of them worked well with 18650 battery size.
Only S12’s tube can fit with 27100 battery, M21B’s tube is smaller 27100 size!
Does anyone have same problem?
I attached here some pictures:
I think he is trying to use some very fat cells… Glad you were able to press it into S12 :partying_face:
Uch sorry, I just have to :person_facepalming:
E.g Liitokala Lii-40A won’t fit.
I think it would be able to fit it without this plastic yellow wrapping, but I just can’t unwrap it…this yellow looks so nice.
Same problem with Jetbeam PC20, won’t fit this Lii-40A
And Simon said it will be fixed in next batch and will fit all 21700 cells like S12 (if I remember correctly)
You mean using a hammer to jammed it into? It could work with Jetbeam PC20, this Lii-40A could be pressed by using a lot of force, but it seems the M21B is 0,1mm thinner and Lii-40A will not fit even a little bit.
When measuring thickness of this yellow wrapping, it is 0,1mm, so both sides are 0,2mm and without it a cell has 21,5mm, so…I guess it could bre pressed… I guess…
Someone here mentioned new yellow Liitokala 5000mAh has 21,3mm, so more capacity and will fit
I only say that because some times tight fitting batteries are hard to insert because there is no way for air to escape the tube. They create a nice seal and feel stuck
Excessively tight fitting battery tubes is a manufacturer's blunder. Some “21” cells may be slightly thicker, and the same happens with certain “26” cells (the overall best 26650s are in fact the thickest at ∅26.7mm).
Nothing to gain with excessively tight fitting battery tubes except unsatisfied customers.
I see that a Rofis Store on Ali offers an AAA flashlight that they say is from Convoy.
It is SS and somewhat resembles the Convoy Ti prototypes, especially wrt overall shape and size. Actually looks better to me.
