So I found a good deal on these Panasonic batteries, and my old 18500 mod was getting to be a little long in the tooth so I started looking through my box of parts and figured the Hammond 1591m box should do well, at least in a pinch... Still had a couple okr t10 chips and pots etc... so a couple hours later( and a bit of swearing) This is what I came up with.... trimmed the box depth to 22mm wrapped it in carbon film to cover the two epoxied screw holes as well as give it some kind of grip
I am highly impressed with these batteries, for me I can get a full day of use at 5.5v on a 1ohm coil, not too bad considering my 18500 version had me carrying around two full sets of spares......
