Yep mine cuts off at about 3.3 or 3.4 volts. My vamo is house bound just now and I use my lava tubes at work because im based outdoors atm and dont want to drop or loose my vamo lol
I tried licking the screen but cannot get it to stick. Added ketchup and that kind of made everything look a bit wrong.
Not that impressed to be honest, but appreciate you tried. Thanks
