I’m looking to replace the stock ×3 Sofirn 3000 mAh 18650 batteries in my SP36 Pro.
I’ll be swapping the LEDs out for SFN43 and would like to supply them with as much current as I safety can.
1 button top Samsung 30Q is $5 more than a non button top 30Q.
It seams silly to me to spend +$15 more for button tops.
Are there any 15A+ 18650 flat tops that would work in a SP36 Pro?
It should be possible to use flat tops like the “regular” 30Q in it, if the tops aren’t bent. You can pry out the plastic RPP ring, its just stuck on with double sided tape.
You can harvest the brass buttons from the convoy-branded buttontop adapter boards and solder them to a flat top cell (carefully), it should have lower resistance than the usual spot-welded button-top cells as well.
The other possibility would be to 3d-print an adapter plate with brass posts to act as contacts.
Something like the ones made for the Convoy sodacan lights, I made the same thing for the Emisar D18 but I doubt it would work on the SP36 without modification.
Edit: forgot something
Yeah, I’m not comfortable with that.
The only 18650 flat top I found that has an obvious proud + contact is this Sanyo but it’s only 10A:
My 30Qs have a proud contact like that, but they came with an old BLF-Q8 from ebay, it’s possible they’re just some weird buttontop I guess. Looked more like flat top to me.
I agree… I have the same flashlight. Button top are probably better solution.
Sony Vtc6?
Molicel P28A?
What do you think?
Cheers
