I saw this video on the EZ Drone YouTube channel and debated posting it. I don’t want this to be seen as fear mongering, but the video does serve as a reminder to exercise caution with LiPO batteries. I don’t know the full story or the condition of the battery in question, so there could be any number of reasons to cause this battery to react like it does.
I like to store my batteries in a military ammo container and I will drain any battery that shows signs of irregularities to 0 volts and get rid of it. It just simply isn’t worth the risk to me.
