Get Battery Percentage

[Fanfan]

Hi,
I'm programming in C++ an interface on a touchscreen installed on a robotino. I am willing to display the battery percentage but I cannot find any function in API2 that would do that.
Does anyone knows how to do that ?

If you feel like testing an early version - you can update the robotino-daemons and have a look here:

Good luck!

You must do some math (heuristics) to get from voltage to capacity in percent. There is no calculation that can do this so you only get battery voltage from Robotino.
