Thank you for the info and including the link. What makes this one the best?

Since the M21A/S21A will only draw 5-6A at max, you only need a cell that has 10A continuous current capability.

Hence, why I recommended the 50E, since it is a 10A continuous 21700.

Well Crap.

This explains why I can’t get my Sofirn labeled (Protected, I think) 21700 into the s21a that just arrived. :-/

Genuine Samsung 30T/40T/48G/50E and LG M50 fits the Convoy S21A.

iJoy 3750mAh 21700, Sofirn 4000mAh 21700 and Liitokala Lii-40A 4000mAh 21700 battery diameter is slightly too big and won’t fit the S21A battery tube.

I’ve read that some people have some luck inserting the Lii-40A 21700 from the head end (instead of tailcap end) of the 21A battery tube though.

New Liitokala Lii-50E 5000mAh have 21.3mm diameter and fit perfectly into Convoy S21A.

Does anyone know the reason 18650/21700 was chosen over 26650 for the L21A ?? looking at the range of good capacity 26650 cells available i would of thought that was a better option?

Does the L21A have a different reflector than the L2? thinking i should just buy the XHP35 Hi emitter, driver and an L2 host and save a lot of aggro trying to get 21700’s ?

The L21A is just an L2 with a 21700 size battery tube, so the head is the same, but with different threads on the tube side.

However, the XHP35 driver is single cell only, so don’t use the extra tube for 2 cells. So only use 1 cell.

Yes 1 cell only (should of mentioned that) I have been searching for a 2s 2.3amp boost driver but as yet not found anything sadly… Trouble is being in the UK 21700 is hard to come by and id need a different charger as well , think il go with the L2 that way at least if i ever find a suitable 2s driver i can add a second battery

Im guessing there is no 6v XHP35 hi emitter available?

Something like THIS ?

Doesn’t NKON.NL ship to UK?

1.5amp is better than a kick in the teeth , but the driver in that L21a puts out 2.3amp taking the 35 hi to its max …

Got to say the L21a package is really hard to beat on value, if a 2.3amp 2s driver exists then putting the 35hi in an L2 is no brainer , but im kinda thinking Mr convoy would have already done it if they were available?

That is an interesting driver!, im guessing id have to use 4x 26350 to get the voltage up enough for 12v emitter but it could still be a viable option , that could work

Where to find this Lii-50E? (I’m guessing the “50E” refers to using Samsung 50E 21700 or similar internally?)
