【convoy】H4 and B35AM options are updated

[zeremefico]

I had problems with rewrapped 21700 cells like Sofirn, with L21A. 50E cells fit fine.

[Amiran]

Got this driver on c8+ and just swapped sst40 for flat white andforgot to apply the led gasket when screwing the reflector bit so might have shorted the driver… now led comes on and off only 0.01 % brightness or something you can only see if you look at it…
Anyone experienced this? Can you reset the driver after shorting the output?? I ordered one from big but don’t want to wait to test the c8 light sabre with flat white.
Thanks

Sounds like shorted driver. It can be fixed by replacing parts but thats pretty difficult.

Question and suggestions (for Simon and/or anyone else).-

What are the actual (modder and tinkerer) differences between the classic 26650 L2 and the 21700 L21A? As far as I know, the L2 fits all 26650s, including the slightly wider, market leading Power Long Battery cells. However, I heard somewhere that the L21A has problems with some 21700 cells, i.e. the tube is too tight. If this is so, I would ask the machine shop to slightly widen the internal diameter of the L21A tubes (to ∅21.8 - 21.9 mm), modifying the drawings in the process, this way the L21A would be more appealing and trouble-free. Tip: Lishen cells are the widest I believe, at ∅21.7 mm with a single wrap, see just below:

Both fit ∅22 mm drivers with a little bit of filing, ∅21.5 - 21.6 mm driver bay. Don’t know how deep is it but I guess very powerful buck or boost drivers can be used. 21700 extension tubes may appeal to someone.

Regarding which batteries fit… my experience:

The Convoy L2 won’t fit the Keeppower protected 6000mAh 26650, as per my test. Some 26650s are also tight (may fit when battery is pushed into the tube, but the battery won’t slide out when turning the tube upside down - so it’s that tight).

The Convoy L21A battery tube seems to suffer the same somewhat tight 21700 (it won’t fit the Sofirn 21700, Liitokala Lii-40A, nor iJoy 3750mAh 21700, as per my testing). Genuine Samsung 21700 and LG 21700 appears to fit.

I can confirm that, the new tube diameter is 22mm and now a Shockli cell fits.
Also the tailcap is shorter

What about the S21A? Is there a new batch with more diameter?

[Blggg]

The S21A from the later batch (at least the one I bought about a month ago) can accommodate the Lishen batteries now.

[id30209]

Simon, is there a possibility to buy just the pill with mcpcb screws and driver retaining ring for S21A?

Send him a message on AE after CNY, he will help you.

I've been interested in seeing the SST40 driver with biscotti firmware making it to the Convoy Store for ordering

The Convoy Store on AE has message that it planned to open on or about February 10th,that's tomorrow.

I think the odds are on it getting delayed further,maybe a couple more weeks

It doesn't look good in China yet.

Hi Simon.
Any news on the Biscotti 5 amp (sst40) 17mm driver?
Thank you.

[oweban]

I don’t remember if it was posted before and it’s difficult to search on my phone - is it possible to get that flat-top adapter for the 4X18A by itself? Would be hugely helpful and far better than me trying to solder little copper things onto batteries.

Hope all is well over there.

+1 on that! Id like to buy a few of those plate adapters as well.

[oweban]

Would be super helpful for other lights like the BLF Q8

【convoy】SFT40 5000K back in stock (sufficient)

Hi Simon. Will a flat-top battery adapter be available for separate sale? [image] [image] Do you have plans to create a flashlight with 3*XHP50.2 or 4*XHP50.2? May be 3*XHP70.2 or 4*XHP70.2? but the adpater is only suitable for 4X18A, i think you can not use it on other flashlights i will design those models at next spring. currently ,i’m too busy

[oweban]

Cheers, was having trouble looking through

I’ll make it work on other lights!
