Here are a couple I built over the last couple of weeks in my spare time, the first is a dual 18650, with a FDV V4 510 connector, I've ran it down to .15 ohms and it works like a champ. Originally this was all going in the 1590G box but I made the wires off the mosfet too long and didn't feel like doing it over so I grabbed the closest altoid can and threw it in
The second one which I built last weekend has a single 18500, mosfet, with a micro usb charger, can only run it down to .4 because of the battery but it gets the job done. The slot for the micros usb is a little hacked up just because I didn't have the right tools on my dremel.
