My SGII does not fully work with the FEH, e.g. the State of Charge displays as blank. Linear-Logic is aware of this problem but no solution seems to be forthcoming. Reportedly the newest SGII's have a different processor that will work with the FEH, and I would hope that Amazon is shipping that version.

I think I will order one from Amazon and give it a try. I really want to get SOC working. Thanks for the tip.
