The thing that shocked me about these is theres only the coating on the case stopping the battery shorting.
When I put the sx350 chip in mine i smeared a layer of epoxy for the spring to sit on for peace of mind.

did you not have the piece of 'insulation' that sat on top of the spring

Nope.
If there was supposed to be something there that might more than likely explain why I thought mine had gone TU.
Picked it up 1 morning and the whole thing was warm and the battery was flat.
Tried another batt and same thing happened so I cut it up lol.
If it was only an insulation issue on a spring Im gutted to say the least.
EDIT:just watched the video posted and mine most definitely didnt have that round moulded piece on it.

yep, that's what wasn't there,the contact assembly should have been cup type posi, spring and a square of black plastic that sat on top between the battery tray and case.

I suppose it's a better mod now with the sx board?

Mine had insulation between the +ve battery spring and case, you can see in the video.

The VTC mini is a great mod as is but I do love them old fashioned pre TC sx350 chips.
My sx chip used to live in a hammond box but when there was the option of putting it in a sleek new case it was a no brainer.
Gutted now to think it was only that insulation piece missing.

"Operation Take Apart" (and put back together!) VTC mini complete.
Very easy to do and straightforward. (My positive spring also had a plastic cap on it)

Cleaned a bit with cotton bud and 70% Rubbing Alcohol (all I had to hand, and even then only a dribble).... fire button operation improved, although still not 100%.
Will try 99% isopropyl alcohol if I get some in.

Thanks for all the replies.


[ETA] - Yes the 510 wires (seen in person) do appear very small for the current they're carrying, even if only for short bursts VapingBad
