Maximum battery voltage?
-
What is the maximum battery voltage for the expansion board version 2? From the technical specification for the battery charger chip bq24040, the max voltage is 28V, so I believe we can use either one cell (3.7V lipo), two cells (7.4), three cells (11.1V), four cells (14.8V), five cells (18.5V) or six cells (22.2V). Correct?

Many thanks!

@bigboy20769 Besides (and while) charging, you have to run the xxPy from the battery, and the maximum input voltage is 5.5V. So the answer is: one cell.
