If you let it charge to completion or near competition wont see much arcing, and if you charge at North American household voltages, less arcing than hot-unplugging at 240v.

That makes sense as I almost never put the plug until my display shows 100%.  I guess that is why I have never noticed any arcing.

> This is very complicated, for unclear benefits. Why don't they implement a "eco charge" button that stops charging at 85,...

They do.  Energica and SR/f have this feature, more or less.

If you're just going to buy the new version of the bike, you can ignore this thread : - )  I'm making something work on my 14SR and sharing info with people in similar circumstance.

I avoid the arc issue altogether by using one of these: https://www.amazon.com/gp/product/B072F9DGRL/

Plug in bike in whatever order is convenient, then start the juice flowing with the remote.  When done, shut off the power with the remote, and then unplug however you like.

This lets me leave the cable plugged into the wall in a hard to get to location, and just leave the plug on the garage next to where I park my bike, with the remote next to it.

I can vouch for the one I linked, I've had no issues with charging the Zero for the past year of daily use.

Not to rain piss on your parade, but you just moved the arc flashing to a relay instead..
It's still there, just hidden from view..
Confirmation on this will be, for you, when the relay fails from breaking the power delivery due to fusing of the connectors.
Depending on the quality of the relay and the load it is trying to break, that will happen anytime between 500 and 5 million switchings.

The idea is to move the spark away from the bike so when it fails, it's a lot easier to deal with.

I'm happy to replace a $25 Belkin Wemo Insight every 500+ charging cycles 😀

And Scotchman's remote is only $15

Way better than replacing some motorcycle component.😀

I'll chime in that an easier to replace and cheaper part failing regularly is a valid solution to an engineering problem like this. If failure is inevitable or unpredictable, try to make it economical.
