I purchased 2 of these mods and have used one quiet a bit but within the last couple weeks, the battery contacts insulators that hold the contacts in place broke on my silver g2. So I broke out my red LE that hasn't hardly been used and after a day of vaping on it, it constantly cuts off on me. As soon as I hit the fire button, it cuts off. I can tap it and it comes right back on but soon as I fire it, it cuts off. Everything else works fine, menus, screen, etc. It just wont fire without cutting off instantly. Any help is greatly appreciated. Also I've used multiple sets of batteries, mainly vtc5a and Samsung 30q's.
