I'm confused a bit. You swapped the words, don't you?
The discharge current is always(!) reported.
By definition
* charging (in OL state):    energy stored in the battery is increasing.
* discharging (in OB state): the load consumes stored energy.

I just asked because KNutClient displays a meter with scale
-15..+10 Amps however (absolute value of) charging current is
tipically lower than discharging.

I thought it is better to clarify this. :-)
