Hi, I've been using my DNA100C every day for about 9 months now, but lately, in the last month or 2 I've been getting this issue where the battery charge indicator isn't even down halfway and starts getting weak puffs and says "batt down." I figured the batteries were dying, 2 Samsung 40T's, both do this on this mod. I don't have another 21700 mod to test. I just picked up 2 more Molicel P45B's and they do this too at around 60% charge despite being completely new. If I immediately change batteries it's fine until I hit that dreaded 60%.
This wasn't an issue when I first got the mod, it might start saying batt down at 5% or 10% charge at first, but it's starting to do this sooner and sooner despite having plenty of charge left. What could be causing this? The mod is a ViciousAnt Primo. Thanks
