I have been using the EGO 900mah battery with Boge 510 LR cartomizers. I am feeling like they run out of juice way too fast. I just filled a brand new cartomizer and was vaping for a little while. I think I get around 15-20 normal vape hits before the taste was effected, which was less than 20 minutes in time. I looked inside the carto after the 20 minutes and the poly looked very used and dry. With my first fill of any cartomizer I use the condom method with the screw end facing up and 35 drips, and I direct drip at a 45 degree angle for refills with about 20 drips. I end up opening a new LR carto every day or two because after refilling a a few times the current one starts tasting funky quick and I notice the poly look a little burnt. Am I doing something wrong? I feel like dripping into an atomizer would not be much different.
