Yeah great little single 18650/21700 mod but with a POS door. Well mine is anyway, so I barely used it from new (too many spilled and dented batteries)
I had tried just putting a couple of o-rings over the door (adds pressure) but they just split /fall off eventually and its an ugly fix. But since it's too good a mod to not use, I had another go today...
So, the better 'fix' is to slip a small 'O-ring' around the door's sprung (-) Pin, at the hinge - fatter the better.
A bit of a fiddly job, but not that bad -requires a small flat blade screwdriver (or alternative) and a pair of cermic / fine and pointy tweezers.
Open the door - Depress the sprung pin under the door hinge with the screwdriver and push an o-ring in with the tweezers.
Make sure the o-ring is NOT caught between the hinge (-) Pin itself and the door contact - it has to be around the pin - or you won't get a circuit obviously.
See - photo.
The idea is the door needs pressure on the outside 'catch' to stay closed - without that, it tends to pop open just with the slightest touch of a finger.
There is online, another method involving a strip down and increasing the throw/ pressure of the battery (+) Pin - thereby causing the battery to push harder against the door.
This 'O-ring fix' avoids a strip down.
It's still a big improvement and the fatter and wider the O-ring you can stick in there the better.
As well as increasing pressure at the door hinge, the rubber gives a little more friction and the door doesn't slide as easily either.
The sprung pin keeps the o-ring from falling out and its all good!
A damn sight better than the POS design was straight out the box.
Hope this helps those who still have this great little mod.
