HI Guys,
I did go the Harley route too and got baffled by the 850$ price and requirement from Harley to know WHY I wanted one... also check other car manufacturer and they all are between 590 and 800 Canadian $.
The first unit I got from Amazon stopped working after a few days and returned it... after a few research, I noticed there was another charger which has a selection button for 10 and 16 Amps. I ordered that one and selected 10amps and it now charges my Livewire every night just like any other level 1 charger would.
My guess is that the first one was trying to push 16 amps at all times and could not level down when the bike was over 80% or so. or it was just defective.
Anyhow, the second model ( Morec with the switch) now works just fine
