Yeah, the main suggestion being "don't forget to actually configure
it!" :)
Reconfiguration after the pack is out of the factory is hard because
it needs 21V on PROG pin, so the right thing should be done from the
beginning.
For that one needs to carefully look at all accessible documentation
for particular cells and then fill bq27000 eeprom accordingly. The
datasheet is quite clear about what is expected to be there and proper
programming will bring more accurate measurements and therefore
improve user experience :)
