Modifying a Fenix?

Has anyone taken their Fenix apart so that the handle containing the batteries is a separate piece from the LED/reflector part, creating a separate "battery pack"? It seems like it should be pretty easy, involving a couple of wires and a mild bit of hackery, but I figured I would check to see if anyone had done this before.

I think it would be really nice to keep the better battery power of the L2D but I sort of hate having the long cylinder hanging off my road bike handlebars and getting in the way- I figure I would just mount the "battery pack" under my saddle or somewhere unobtrusive.

I thought about it but I'm too lazy. Much easier to mount the entire flashlight to the handlebars and switch out batteries. Looking at the light head there are 3 points you need to connect to.

1. The middle pad is where you would connect +3volts just like the batteries do.
2. The body of the flashlight is where you would connect - because - gets to the head of the flashlight that way
3. The pad on the circuit board that is near but not touching the body of the flashlight is how it knows to go into turbo mode ( - )(twisting the light head connects that - to that part of the board).

Let me or let us now how it goes. I use my flashlights for camping and around the house so I don't want a dedicated bike light.

Thanks for the specs. Not sure about what the best option would be, I am thinking mounting the head right off the stem under the handlebar would be discrete but still usable, with the body underneath the saddle and a wire carrying it back.

Ideally, Fenix would come out with a screw on attachment that did this sort of thing, preserving the original function of the flashlight if need be.

At the same time, maybe it would just be easier to just use an L1D which isn't as long and carry an extra battery or two.

I suppose the reality is I like the DiNotte form factor, but the cost is too high without a good sale.

I reason I'm thinking about getting the Fenix is because I don't like strapping a separate battery pack.

if it ain't broke, don't fix it.
I wouldn't try it on a pricey Fenix.
that said, I have a UltraFire 3W LED assembly that I would like to mod this way.
I tried it with a rechargeable 3.7V LIon and it works, just need to find the right housing.
that's what I get for buying a fenix copy and not the real thing. the threads were stripped
and wouldn't hold anymore.

Have you actually tried the Fenix? Before I bought one I thought it might get in the way, but surprisingly it doesn't. They fit quiet nicely on road bars.
