So I finally got a Sub-ohm set up at 0.5 ohms on a magneto/igo-w combo with a MNKE 18650 battery. I feel as though I'm only getting 1-1.5 hrs tops of good vape time on this setup. Is this normal? I find myself constantly switching out batteries and charging one while I'm using the other. I was hoping that it would last me for quite some time, but it isn't. Is anyone in the same boat as me? Thanks, and Merry Holidays to you guys on the forum. I learned a lot while being here, and I'm always looking to learn more.
