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.
I don’t think so, the light is on Simon’s Convoy store for over 2,5 years, i have never seen replacement parts for that particular light, but you can always ask Simon.
Can you source a specific tint range of SST-20 95CRI LEDs?
I used FB4 (4000K) in the Clear C8+, and that gives a nice tint, if I drive the LED moderately hard (3.5A). For some applications, I would like to use a bit warmer tint, but in those cases, JB4 would be too warm for me. Could you please check, if you could source tint GD2 or GD3? That would be the ideal choice, which could give a result called ‘soft white’ with being just slightly under 3500K?
