Hey all i just received a smoktech magneto and i seem to be having extreme misfire issues. I am using the same efest imr 1830s i used in my vamo. it seems as if the flat top battery is too short. i can here it moving inside when the magneto is collapsed to its smallest. The thing is this did not seem to be the case earlier. it was working fine then out of nowhere it stopped working. I know it sounds crazy but it misfires less when i hold it upside down or pressed really hard. Could i have crushed my battery or something and now it wont fit? when i get home i will stack the 18350s just to see if it fires every time. i was about to order a set of aw imr button tops but it just seems like a waste of money if my battery can work.
