Actually thinking of my last post - pretty unlikely the heater being on would coincide exactly with opening a battery that had gone to 5 V. But It strikes me that Relion would really want to get to the bottom of this - especially if they thought this story might spread and hurt their reputatio

Hey Jay, So at the 4:35 mark of this quick review of available LFP batteries on the market at the time (2019) - Will Prowess states that "they (Relion) are the only battery that has a built-in battery heater (I think he was implying as standard equipment and not an option). Is it possible th

Damaged Li battery safety, For information only. Our procedure to decommission any suspect failed LFP cell is to apply small load (<0.05C) until all electrochemical energy is removed. This should preferably be done in a safe area outside. After full discharge, physically damage the cell terminal

Hey Jay, So I don't believe ReLion batteries are openable - so it's most likely that when he decided to open it he cut into it and shorted the leads. As for recycling - first is health safety!  I'd suggest he contact the manufacturer and get specific instructions for safing the mess.  Will P

Very few details...What does it mean "he opened it up"  I would even know how to do that with the L-ions I've been around, seems like its something a manufacturer should be doing.  Temperature? charge rate? recent usage history? Age? Was it disconnected? Did contacts touch a conductor?
