Yes it's possible to stack some more chips.
Sorry I looked only at the driver and I didn't realize you have written "Shadow SL3", I thought it was the JM26 driver.
Anyway, as I was suspecting there are 4 empty places on the JM26's driver, not 3.

oh man
i might have to buy an sl3
that’s the best news i’ve heard in awhile
Great news, thanks
So can I stack any number of chips in any position? Like just one chip anywhere, or an extra chip on each chip?
Cheers
Matt

Any number on any position (of the 12).

Great, thanks :bigsmile:
Wow, maybe making a 9 amp SL3 is easier than we thought. >)
It is, but it’d be rough on the cell, can king Kong inr’s dole out 10a?
Edit, its my birthday in February, I think I’ll be ordering an sl3 and ten 380 chips or so….
I think that’s more than recommended (2C?), and I wouldn’t make a habit of it w/ anything but IMR, or similar…
edit: so where’s the best price on SL3?

Yeah, hopefully
Only thing is the heat sinking. The 3 leds are bonded on a single aluminium star that is glued into the head of the light, so the only area of contact with the head is around the edge of the star.

+1 - they are all in parallel so doesn't matter where. That's why you can even remove some, or double stack (3 high) them. But, oh boy, pushing a single 26650 over 5 amps? Not sure what the limit is on high qual batteries... I know there's been things published here on BLF about that. 6 amps would be nice, 2 amps per LED, but 6 amps on 1 battery? - only the best batteries, maybe...
Not sure, but 9-10A even on an IMR may be unrealistic -- should check this.
how thick/deep is the hollow space under the star?
I just ordered a couple of these Samsung INR18650-20R They can do 20A
I have a couple of mnke 26650’s that should do the trick too

Supposedly King Kongs can haul more than 10 amps easily. Check out HKJ’s review here.

At a guess, there is about 25mm between the star and driver, but a lot of it is taken up by the glue. I suppose it will be thermal glue of some sort though.

That big aluminum board stays on another piece of aluminum which is basically machined from one piece with the head.

Ok, that sounds good
I have some king Kong inr’s already………must……not……pull…….trigger………yet. J) 0:)
WOW! This is great news! I guess both flashlight has the same driver! Talk about making it easy :bigsmile: This means my JM26 has room for 4 extra 37135 and NOT 3! There’s enough room under the driver so stacking is not a problem. Looks like I’m gonna buy the SL3 and mod it. Tell me how it goes, MattSPL! I might do the same. I’m gonna mail Hank at Intl-outdoor to see if he has any extension tube for sale together with the SL3!
The driver stops where the grooves end, so there’s enough room underneath:
I’m really happy right now :bigsmile:
thanks for the link to those cells matt, I think that’s the highest rating I’ve seen.
The other IMRs I checked when we were last talking 9A sl3 were 18A
I was asking about the space because I’m wondering if it’d be possible to add a custom machined copper heatsink
might not be warranted if the path from star to body is good enough…tests will tell
You can't use an extension tube with the SL3, the max voltage of the 7135 chips is 6 volts and 2 li-ions would be 8.4 volts.
