Like a generic IMR? Hmmm.... those don't last quite as long as the good ones... but I'm thinking you'll get a good 15 hours out of it. I might not be the best one to answer since I haven't used em in a while. Anyone else? how long do your 'with kit' or generic imr batts last on a charge?
As for the carto, totally depends on you and how much you vape, how thick/dark your juice is, if its in a dual coil tank or not. I get less time out of dual coils than single coils. I vape 1.7ohm smoktech single coil at about 4.4v, and one will usually last me a good 3 weeks or so, and then it'll get gunky and want cleaning. But after that might go another 3 weeks or so. I go thru about 15 in 2-3 mos, but most of that is cause I vape a whole bunch of flavors. Now with dual coils, I didn't get that long, and if they're generic and not smoktech i'd say maybe 2 weeks or so. If its in a tank, maybe a week to 10 days, but you can extend the life by cleaning em when they get hard to hit, and get another few weeks out of em. I almost always want to stop using them because performance is funky long long before they actually die. But all that being said, you'll need a LOT more than 2.
Crystal Clear Vaping has a killer 15 carto deal with free drip tip of choice and free shipping, and that's about the cheapest way I know of to stock up. They have the 1.7single coils, and also dual coils, and things like Boge 2.0 and 3.0. Not a huge selection of cartos, but they're all the most popular ones, and you can buy them in the 5 pack, or cheaper per carto in 15 pack.
