I had a very good recent experience with Lectric's customer service. My control switch was damaged in an accident, and I emailed them asking about availability of a replacement switch. They quickly replied that they had the part (including the screen as the switch is tethered to the screen)...
Thanks for all the work you did on this. My voltage reading on my month and a half old XP is quite a bit higher, 55.1 volts when fully charged, but the voltage seems to fall off very quickly. Bigcanoe posted a chart with a similar scale that he found in yet another Lectric thread...
