I am looking for a charger for 14500 li-ion batteries. I am not necessarily looking for the one that charges the fastest but more for one that is reliable and safe. I know the li-ion batteries are more dangerous if they are not charged properly and I do not want to have one explode on me while I am charging it. The thing that has me worried is that some of them I have found are $7 or less and I am not sure if they are of good quality. Does anybody have a suggestion for brand and the cheapest place to get a good one? I do not think it matters at all but I am using them in a 3.7 box mod. The brand of batteries I am using is TrustFire. Thanks!
