I'm a newb and it's my first post. I have been using the V4L batteries for about a week now and today I noticed a really bad taste when vaping. The taste I've been getting is the same kind of taste you would get if you lit the filter side of a real cigarette by mistake; its like a really foul funky taste. I even get the taste using brand new pre filled carts (I have V4L, Volt, and Halo G6 carts and have tried all of them today.) Any ideas why this is happening? I have 4 short batteries (only used them for a couple days) and 1 78mm, and get the same thing on all of them.
