Took delivery today of an aegis x and two Molicel P26A batteries (from fogstar so I know they're genuine). Charged them and put them in the mod, two vapes and one of the batteries dropped a bar. Thought, maybe I've not charged it properly. Took them back out and put them back on charge (xtar charger). After a few minutes it read full again, so put them back in the mod and the same thing happened, took two vapes and the battery dropped a bar. Took them out again, charged to full again, checked the contacts were clean etc and same thing again. Gave charging in the mod a go, again, same thing, got to 100%, three vapes later drops a bar. The reading does follow the battery if I switch the battery to the other side of the aegis. And it shows in a different mod. Not vaping at stupidly high wattage either. 45w Have emailed fogstar but don’t expect a reply till Monday so thought I’d ask as maybe it’s just normal for newer mods. The MVP4 has been my main mod for the past few years. I’m assuming the battery is faulty. But I may be missing something so always worth asking for a second opinion.
