Our selection of vape batteries includes exclusively high-drain batteries with IMR or INR chemistries, which are ideal for use in mechanical mods, as well as today’s high-current regulated mods. High-drain IMR or INR batteries are where most of today’s research is going, so these batteries have better capacities for longer life between charges, and higher current - amperage, or "C rating" - for higher wattages and lower resistances!
