I have read on here for a while to get help, and this is my first post. I recently bought a MVP 3.0 last month online. Everything had been working fine other than the coil readings being all over the place. I know that they are suppose to have a + or - of .2 on the reading, but it sometimes is all over the place. The battery also seems to be inaccurate with its remaining life when it reaches 3.75ish V. The new problem that just started happening ago is that it is turning itself off, without me clicking the button three times. I have read similar posts on here, but others were slightly different than mine. The crazy thing is, the device will not turn back on unless I plug it into a wall charger. I was told that it could be because the coil reading dropped under 0.4, which is when it cuts off, but my 0.5 coil OCC typically reads between 0.8 to 0.9, but sometimes over 1. I have never seen the coil drop below 0.5, I have never even seen my 0.5 coil read at 0.5. I am using a Kanger Subtank Mini. Has anyone else experienced this problem. My Gladius tank works fine on the battery, and it never shuts off when I use it. I need help figuring this out.
