Hi! My fiance recently got the Smok Osub 80W Baby Kit. It worked great for a while. But recently, she's been getting low battery warnings, check atomizer warnings, and do not abuse products warnings occasionally, to where she can't take a hit longer than 1 second. Tried multiple different batteries, 2 different coils. The do not abuse products and atomizer warning are gone, but yet we still have the battery warning, and we're wondering if there was a fix for it? We're using filled charged batteries, around 50 Watts.
