If your eGo mega dual coils will not fire on your battery, here is what to do:
I've seen several ego
batteries and ego clone
batteries that had their center pin sunk in too far to work on a charger. That's also a common complaint with the Go-Go and a few others. Hoogie reminded me that lifting the center post on a battery can solve these sort of problems. That doesn't happen to be the problem, but it led to the solution.
It is the center pin in the 510 connector on the cartomizer. I used a dental pick with a 10 degree angle, but I'm sure a small paper clip or other device will work. I stuck that in to the center hole in the 510 connector on the carto. it has to go in a couple of mm to grab hold of anything. I lifted the center pin of the carto just a tiny bit. then I made sure the center pin was centered and not shorting off the sides. Then - I vaped it on every battery it wouldn't work on before.
To give credit where credit is due: Thanks to Hoogie from madvapes for the
reminder of the center pin, and thanks to PBusardo in his
video review of the Boge Revolution 2.1 for mentioning the center pin on a carto can be lifted and showing a technique of how that can be done. I claim no rights to such intellectual property. I am just preaching the word as it was taught to me! (and, yes - the preceding paragraph was intended as a jab at basilray and others just because they deserve it and know why)
