Well, I added the link because, personally. Then take the battery off the vehicle and lay it on the hot ash, removing the filler/vent covers from the top. In my experience, I have seen a lot of people making bad choices regarding batteries and related components. The idea of using the battery pack as a structural material was a technical nightmare, but the great mechanical design made it quite safe and brought down the center of gravity of the whole vehicleclose to the ground, thus increasing the stability and maneuverability of the vehicle. Nonetheless, it's important to note that in multi-cell batteries, the damage caused by under-voltage conditions will increase as the difference between stronger and weaker batteries increases, and that difference will be increased as a result of such damage. 12.0 volts or less Your battery is entirely depleted or flat at 12.0 volts and should be recharged as soon as possible. 11v is good that means all the cells are holding a little bit of a charge and none are shorted or completely depleted to 0v. Since each module is 5.5 kWh and we have 16 of those in a 90KWh Tesla battery. In cases where a multi-cell battery pack is used for purposes of storage capacity rather than current-handling ability, I would suspect that a battery pack with electronics to draw more current from stronger batteries could yield better lifetime behavior than one which simply wires cells in series, but I'm unaware of such designs being commonplace. The red circle in the below image shows how cells are connected using wire bonding. MathJax reference.
