1. Yep I F/U but now I have corrected the errors. of my way. But from my vantage point i think my explanation was more on track in answering why their were voltage difference in the 3 trucks mention - two brands I never heard of but I've been out of the business 11+ years. The Chines muck things up at times.
2.) Yes like you always presented the electric truck buyer with a proposal on 36 v units to provide them the same info "me too" sellers guess did and provided a separate proposal for the same unit with 48 v at the same $ but with - tangible customer benefits - then the discussions & demo begin (48v unit)began. Likewise, when a customer wanted a 5K cushion LP proposal I provided a 5K electric truck proposal w/48 v to show speeds were comparable and a ROI via longer economic life (7y vs 5y), lower routine maintenance, fuel savings and more environmentally friendly, and a 7 year $1.00 option contract or FVF lease and a possible greater depreciation tax deduction.
If my info went over the OPs head that is OK, they certainly have the option to ask questions. But in my book it is always better to provide more info than not enough -
