Battery stats in Ubuntu

[xalius]

Thats nice to see since I am about to order a battery for my Pine. The PMIC has some more features for battery charging and monitoring that can be / need to be configured... that's something that needs to be worked out I guess... it has a "Fuel Gauge" feature for example that needs to be calibrated (like the battery gauges in the smart batteries for laptops ...) and programmable charge current / cut off voltage....

Just FYI, you can also read out the system voltages (set values) from the PMIC from the sysfs:
