Min / max cell voltages

[Davidjones75]

After full charge max 4.17v min 4.14v ,battery voltage 449v is this about right.

Yes, 0.03 volts cell difference and 449 volts at max charge indicates a balanced battery and the latest BMS software installed.

That's better than a lot of other members! I'm afraid it'll only slowly deteriorate from now!

Do we know the exact chemistry of the Catl cells in the MG ZSEV ?

For comparison the good old I-miev has LMO/NMC cells ( lithium-manganese-oxide/lithium-nickel-manganese cobalt oxide)

And they charge up to 4.105V/cell and the BMS always tries to reach 0V delta for a perfect cell balancing. Edit: it just seems the balancing capabilities are a bit weak on the MG (1mV/hour) this is ridiculously low. Saic should consider a design update...

Thank you
