Hey guys, couldnt find this topic..maybe i'm blind but i thought i would ask. Been using regulated mods and havent ventured into unregulated yet, but am thinking about a purchase. If i were to get a Smpl mod(Clone) what would be the safest battery for it if i were to build below .15 or even lower? i have two Efest IMR 18650 - 3.7v 2500 mah with 20a/35a discharge. would one of those be safe or should i look into a safer battery if i were to go unregulated?
