[Power] Fwd: Charging XO-1 batteries having extreme cell imbalance

[James Cameron]

Yes, that's a workable procedure.

Also the operation of the cell balancing circuit releases heat in the
vicinity of the switching MOSFET on the PCB in the battery.  So with
careful monitoring of the nearby temperature sensor a few millimetres
away, or a thermal probe, you can deduce when the cell balancing
circuit is working hard.

A technician may also provide external charging current to the pins on
the battery.  The battery protection circuit shall operate to prevent
overcharge or fire.  But this won't update the capacity estimate
stored by the battery.

During one test, I used an Arduino Uno to communicate with the battery
chip.  It is relatively straightforward, using public datasheets.
