ZMAx V2 Fire Button Sticking

[alpman]

I purchased a SS ZMax V2 from MV at a killer price last week and I'm having a problem with the fire button sticking. I'm using a Panny IMR Hybrid 18650 flat top battery. It seems like the battery spring puts a lot of pressure on the main board, causing it to get a little crooked in the tube. When this happens the fire button sticks. The only way to get it unstuck is to press it repeatedly or bang the tube against my palm. Has anyone else had this issue and is there a fix? MV claims they haven't heard of the problem. They are willing to replace it but they are out of stock for about two weeks. I thought maybe I could snip a coil or two off of the battery spring, but I didn't want to void my warranty either...help!!

I'd try not screwing the end cap all the way so it doesn't put as much pressure on the electronics board to see if that fixes the problem. If it does then your probably right. If it doesn't fix the sticky switch problem then it's probably something else making the switch stick.
I've also worried about too much tension on the board due to the pressure exerted by the end cap spring. Even though I haven't had that sticky switch problem I do use the extender cap (the one you're supposed to use when using the 18350 batteries) when using the 18650 battery because it puts less pressure on the circuit board.

Make sure the spring is seated well in the cap. Mine was not and by putting pushing it back into place I relieved some of the spring pressure.

The spring is too long so I used a pair of pliers and heated the spring gently to compress it by about 1/4". The battery still fits snugly and the button has not gotten stuck so far. I think I fixed it!!

I have the same problem with my Zmax v1 using 1.8 ohm vivi nova.

Just cut the spring.. one coil at a time until it is short enough... that is what I did!
