Buddy Balance
I am checking and balancing 22 Calb CA60 cells for a friend.
First I am checking each cell voltage and label it. There was one cell with a higher voltage.
While I was charging the whole pack in series, I already had to balance this cell with a 0,1 ohm resistor because the voltage was going up in the sky.
At the end I had a pregnant cell.
A sure sign for a dead cell.(

Tesla Fuse Connection
Tobias has a battery module from a Tesla Roadster.
The 18650 batteries are connected with a small wire to the main board that works like a fuse. When the current is getting too high because of a bad cell, the wire melts and this battery is out of the pack.
