18650's in my old E2D

Gorram · Dec 19, 2011

Greetings fellow flashaholics (luminous geardos?)

I've searched, but not found yet the answer to the above query:

"Can I safely use an 18650 in my mid 2000s Surefire E2D?".

Ya, I know.... another noob question. :shrug:

Cheers, G.

A 17670 fits snugly in the E2D tube. An 18650 is way too large for the stock tube... then you have the voltage issues.

Short answer... NO for stock E2D!

That's the trouble with getting into something new.... Lots to learn!

Thanks SunStar!

I'm not even sure if 17670's will fit 100% of the time. Some bodies will take it, some won't IIRC.
E-series experts, is this correct?

With a stock E2 style tube it is luck of the draw if a 17670 will fit or not. An 18650 in a stock E2 tube is a no go for sure. But.... The tube has enough meat to be bored out to 18mils and fit almost any 18650.

I highly recommend this mod and Barry AKA Presisionworks is very good at doing this difficult task. I love the E series platform great Lego and with an 18650 it's awesome.

Wow I didn't know that I have been told on this forum several time that there is not enough material where the head threads on...

As for fitting a 17670 if the tube is too tight for a 17670 it doesn't take much work with sandpaper and a drill or even a Dremel to make it work

The area were the threads are is the thinnest but it still is robust enough not to break. I had some minor contact issues do to the thinness when using a VME and a M61 but I worked through them easily. The problem was I think the M61's contact diameter was smaller than the 18mm bore and cause the issue. Tightening or loosening the head would solve the issue temporarily. I solved it with a small bead of solder.
