Tom, are you saying that you wired 3 wires (pos to battery bank and 2 negs from source neg wire) to the 3 pin aux power input? do you happen to have any pics of this?
yea, delivery time was terrible. hobbyking has a US warehouse, but it was shipped from singapore, and took 2 wks.
Zap, thanks for that link to the e-bike info. one of the guys there seems to indicate that it can get power from either the source or the load, so i guess i'll just have to try and see what happens.
