Hybrid / EV Battery Cell Balancing
Bolt EV/EUV sections(rows) will arrive custombalanced to near the average cell voltage you provide
at the time of order. You must follow service information
to complete a short, final balancing once installed into
the battery pack. It will be faster to balance the
replacement section if the state of charge displayed in
green bars on the instrument cluster is less than 100%
at the time of ordering. Bolt EV/EUV sections cannot be
ordered above 4.0v average cell voltage. Use software
revision 10 or newer for the EL-50332 battery balancing
tool.
