Hi. My concern is that in bottom firing mods, the positive pole of the battery is always connected to the positive pin of the mod, which in turn is connected to the atomizer. When the atomizer heats up, the heat travels to the pin of the mod then to the battery. I remove the top cap of my mod and check the positive pin and is indeed heated. Is it not a concern because as far as i know, the battery will directly receive most of the heat. That's why now, im using a slider mod instead of bottom firing mods, because in the former, the spring is located above the positive of the battery. That makes the positive pole of the battery not in constant contact with the positive pin of the mod. Any view on this?
