I'm wondering if anyone has any ideas for why my resistance is jumping from like, .28 to sometimes, .44 then go to hit it and bam big difference. I'm running my ipv4s with my Harakles plus tank 316 ss replacement coil and it did it once before with the same kind of coil my batteries are barely under half way,and it also gave me a check battery when they were at half on the battery bar. I'm thinking of just swapping out and putting some fresh batteries in and see if that works.any ideas would be appreciated. Thanks
