I have vape kits with internal batteries.
I have read that overcharging batteries - in my case unintentially leaving them plugged in for a while when they are fully charged - can lead to problems and shorten the life of the battery.
This surprises me. I have other devices that use lipo batteries and they have an automatic cut off when charging is completed. Don’t vape mods do this?
I use two kits: an Innokin Endura T22 Pro and an Eleaf Istick Power 2.
