Hello , I purchased a "Battery-eGo-1000-USB eGo-T tank Passthrough USB Battery 1000mA" And have used the Ego Mega carto's from vapingzone.com, and the boge 510 LR carto's from a local shop, wondering which of the two would perform better on my battery, I also have a LR 1.25 Ego batt that I switch between however one of the two batteries burned out my carto's pretty quickly < 1 week. Do you have an Idea which I should use between the carto's I buy, and the batteries I have? Thank you if you have an answer. -Sam

Also if anyone has a top pick on where to get new carto's, I know of vapingzone, and topvapor.
