Not a home-made mod but a conversion of this https://www.fasttech.com/p/3976200 to mosfet/LiPo

A nice compact mod, but sadly powered by an 18350, of which I own exactly none
.
First thing was to get some battery action and these looked like they'd probably fit with a little fettling. I got 3, two would definitely go in, but a bit more capacity and a higher amp limit for lower voltage drop does the world of good.
There's not much room for the switching mechanism and I like a low voltage cut off on my mods too, so I made a little board which is activated by the existing switch it's available here.
I had to modify the internal sled to get the rectangular pack to fit where the round cell went and to get a wire through to the positive pin. I started by removing it from the top cap. There are two pins which secure the sled to the cap. I decided to use one as the negative connection.

Next the battery pack, wrappers were removed and the cells soldered into parallel

Then soldered to the switch board

The sled was then re-attached to the top cap with studious use of a hammer and a punch to get the pins back in.

The battery fit was a bit too snug so out with the dremel to remove some material from inside the case

And it works!

At 780mAh I've got a very similar capacity to an 18350, but with a 27.3A continuous current rated battery. 0.4 ohm build is vaping lovely

If a thing's worth doing, it's worth overdoing.
