hey guys, i have a setup from V4L, well me and my gf each have a set up, i have autos and she has a button, and i was wondering, do they have a timed shutoff of a heat lvl shut off. sometimes i can take a drag for maybe 4-5 seconds before the power will shut off and sometimes its only 2 seconds. im wondering if its a facory setting that shuts off after time of if it shuts off when it gets to hot to save the batttery and cart. thx for your help
