Hello! I've recently started having an issue with my ipv mini, I bought it off a friends husband a few months back and has worked great up til about a week ago. Its hard to really explain. It works but feels as if the power is cut down a little, and also has a delay firing. Watching the battery indicator it goes from the current level down lower (like it does normally when firing) but bounces back up to the current charge and down constantly. There also is a clicking noise. I've pulled it open and inspected the board and I'm not noticing anything that is broken or fried. The sound is not a spark, nor do I see anything. I can't pinpoint where its coming from. I took a video of it, but not sure how to share on here. Any idea what may be wrong with it? I've cleaned all the contacts, and tested different tanks, and popped battery in my other mod and that works just fine. I asked her husband who has a few mech mods and is a pretty advanced user and he has absolutely no idea what it might be.
