Yep, that is correct. There is a capacitor in the controller that holds power for quite a while. They did have me checking on the bike side male pins.So correct me if I am wrong, you were checking the battery voltage at the farme mounted male connectors and not the female connects on the battery it self? I recently checked my voltage when I had the battery for charging (never charge it on bike). At the battery terminals I saw very similar voltages as you the peak battery voltage was 54.5v.
You have peaked my curiosity so I will be checking the male pins on the bike after removing the battery. I'll report back my findings.
I saw in another post you had issues in trying to get your bike (like I did). Now that you've had it, how's it been? And I saw you also had a KCMO phone number. I live in KCMO and thought that was just a fake number they gave me to make it look like a local presence. Doesn't matter really, it's a Skype number that is never answered and has a generic, non-Himiway message. I think I've been had. Can't really say, taken for a ride. That's what I want to happen.
