Whats inside a lithium battery & can it be repaired if it gets too low. Watch & see

[ambulancekidd]

I watch a couple of guys on You-Tube & today they were doing a job on a car which has a lithium battery which had become flattened & switched itself off, so it refused to charge up.
It dawned on me that this might be of interest to forum members as many have switched over to lithium.
Sorry the video is a bit long winded, but the interesting bit is all there.
Hope everyone enjoys the item. The interesting bit starts at about 12mins & 30seconds in.

Interesting. I have a Relion LiFePO4 and these are their instructions if you suffer a low voltage lockout.

“ For some issues, such as BMS protection against low voltage, your Relion Battery can be reenergized by applying (jumping) 12 volts to the terminals, much like jump starting a car battery, this can be easily done with jumper cables. If this does not work, it will need to be charged in parallel with another battery that has enough voltage at least 10 volts in a 12 volt battery, this allows the charger to detect a complete circuit. You can use any type of 12 volt battery. Connect your charger directly to a working 12 volt battery. Then, connect your Relion Battery in parallel (positive to positive, negative to negative) to the first battery. The Relion Battery’s BMS will reenergize, bringing the battery back up to its voltage prior to the BMS kicking in. After about 20 minutes, reconnect the charger directly to the Relion Battery, and the charging process will continue normally.”
