Any info on these? 30amp discharge sounds great for sub ohm vaping but besides that idk much about them. Trying to figure out if its a safe chemistry hybrid li ion like panasonics or if its just a li ion battery. Brother just ordered some for his mech and I just want to make sure he isnt going to blow his face off. I told him to get aw IMR 18650 1600mah but think he is sold on these. thanks
