i got a free 510 auto bat with an order of flavors from flavors by eliquid store --the carto that came with was pretty weak threw a boge 2.0 ohm on there and its kind of fun (usually use ego batteries} will this fry the battery it's not truly low ohm but i can't remember all the little cautions about MOSFET this and battery that...is 2.0 an "LR" not to be used on auto batteries?
