Hi guys, I have been doing some research around here as well as ECF but I can't seem to find anyone that knows where they would sell a 26650 bottom fire mod. Maybe it just doesn't exist yet. Point is, I've seen reputable manufacturers making some beast 26650 batteries. I'm a die hard dripper and being able to buy a 4000mAh battery with a 50A drain rate would be my dream. Of course I won't generally use more than 30A, I'm more interested in the batteries nominal compacity. So far all I have found is side fire and wired mods with a master switch. Any help would be great.
