I'm currently using an Aegis vape with Blazer Pro coil and a Sense tank....AWT IMR 26650 5200MAH batteries. I want to know if there is a better battery I can use be cause once I hit it a couple times at 100w I have to lower my wattage to 90 and keep getting lower on wattage until I get to about 60w!!! Then I have to change the battery....This shit sucks!!!! Thanks guys!!
