Will there be a software option to configure these specific to the battery we want to use? (ie. 1A+ charge current for high capacity batteries)
Obviously the chip supports up to 2.8A charging, but thermal management becomes an issue. What is the functional limit due to lack of active cooling?
Current there is no software option to do so due to reliability concern. Just like you have mentioned, if somebody just crank up the charging current without knowing the consequence, it can become a disaster.
What is the charge current set to by default? Will there be any way at all to access the control registers or modify firmware to change it? (not an app that any user could install and mess with).
The PMU datasheet AXP803 already published in Pine64 wiki site, yoy also welcome to check out. I don't have the default charge current info handy and will publish when received.
