【convoy】H4 and B35AM options are updated

My M21B works with Samsung 40Ts, an Aspire 21700, and a protected, button-top Wuben 21700 that measures ~21.5mm.

What cells are you trying to use?

I think he is trying to use some very fat cells… :smiley: 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)

I dont recommend this but if it’s that close you could probably take the head and tail cap off and slide it in just the tube then thread both ends on

Yes, you’re right.
I’m using Lii-40A battery for my testing. I have that kind of battery only!
:person_facepalming:

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 :wink:

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.

Do I just remove the NTC or remove and bridge NTC?

fluke, if it's an NTC just remove it.

Thank you.

Need a bit more help.

The Convoy M3 driver has the NTC on the spring side of the driver.

Looks the same as the earlier photos in this thread.

But I need help, what is this blue square sticky foam type stuff on the board in this below link - shot?

@fluke, that is a thermal pad.

It is important that you keep it on there for optimal thermal performance, or even replace one that’s even better.

Hi thanks.
I assumed that was what it was.

I have some on order to replace it, typical de soldered the driver and the NTC was on the spring side, thermal pad thing took a battering.

That thermal pad, in itself, can't do much to cool down the boost integrated circuit, or does it?

Please refer to this thread

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.

Is that actually a Convoy?
I thought there were issues with the driver?

It is. You can found it also in Simon’s shop.

Thanks for the info. The price is much better. :slight_smile:

Now it opens a number of questions. :slight_smile:

  • Will there be a Titanium variant?
  • Diameter?
  • Does it accept 10440?
  • Will it be available as a host?
  • What is the driver diameter?
  • Will the driver be sold separately?

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.

Hello 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?
