I approve of the command load. I don't think the battery state of charge
constraint checker correctly deals with setting the long eclipse flag -
both this ATS and last it said that the state of charge got too low the
moment the long eclipse flag was set to false, with a lowest charge level
of zero (!). I'm not sure what's going on there, but it's not
representative of reality. Setting the long eclipse flag is only marginally
necessary for the 1/16 eclipse; with the long eclipse flag, the cell
voltages should only fall to around 3.85V during that eclipse.
