Cost weight for battery dis/charge

[purcell-lab]

Like to start a discussion about the battery cost weights.

I don't like to discharge my battery for less than 0.10 $/ kWh and I find adding this to the cost weight had the desired effect.

I do notice it doesn't seem to matter if I add a factor of 0.1 to either the charge or discharge weight both have the same effect.

Update: These weights can be specified as runtime parameters, which I think is part of the 0.11.x update:
