i have efast 18650 2500 mah, 35a. i know its probably not a good idea, but giving the safer nature of these batteries im not extremely worried, will it cut the life of my battery if i were to leave on charge for an hour, take off, have a vape, than put it back on? it seems that these take way too long to charge and at the moment i dont have any backups. am i hurting the battery, or am i ok by doing this?
