If you're not going to let the bike get to 100% is there a better, or preferred, method to stop the charging?
Is it better to stop the charge at the bike "press mode to stop" or is it better to use the "Stop Charging" feature in the charge provider's app or on the charger?

I would have to say at the bike, that way it releases the lock thingie on the charging head. If you turn it off at the charger, it may not disengage properly and you'll then still have to stop the charge at the bike again anyways, to get it to unlock the charge head.

"At the Bike" is going to be your best option and really should be the only option to consider. Energicas have the ability to set a charge limit if you do not want it to go 100% for some reason and will still balance the cells properly at cut off point that you set.

Agree to disconnect at the bike.
Not sure that cell balancing occurs below the last few % near full charge. Balancing only occurs at the upper voltage limits of the cells. If you set the charge limit to 80%, it will stop there but it will not balance the cells.
Please correct me if I am wrong and direct me to some documentation. Endless disagreements about the whole cell balancing thing, how and when it occurs...

Initializing the charge stop from the DC charger screen or from the charging app (elvah, Shell recharge, EnBW mobility) often produced error codes on the bike's screen and/or in the app. But the bike's codes dissapeared always quickly without a trace. But it could take some 20 seconds until the charge plug was finally released from the bike.
Now I disengage always by pressing the mode button. No errors, no waiting.
According to my experience balancing begins most of the time at around 95 % SOC.
Had it start at 92 % once and one time at 98 %, so it seems the 95 is not a fixed number.

Happy to hear that the everyone uses the mode switch to end a charging session. This ensures that the pin on our charge port will retract unlocking the cable. If you do stop the charge via the charger you may need to power cycle the bike to get the pin to retract.
The balancing process starts when the first cell chain reaches the preset max voltage. What % SOC the battery will start balancing depend on the delta between the highest and lowest cell voltages. The bike will show a SOC of 100% once the cell voltage delta is within the set range.

^^^ Thank you @Demoni !!!

I've experienced several "Charger Fault" errors when using the mode button to stop a charge session. Usually it goes away when I key the bike off and then on again, but I didn't know if that was normal.
I always have this little fear in the back of my mind that I'm going to stop the charge and the charger will brick the bike.

i think it's just more software quirks. I have had several charging 'goofy shit' events myself and so far nothing has ever been serious. Just cycle power and everything is fine. The key not in range coming in during a charge seems to be a major cause of a lot of the little buggy stuff you see as well IMO.

But there sure are a lot of little bugs in the Experia. I normally get the message "you may now disconnect the charging cable" when I have been riding on the freeway for ten minutes after the last charge was over and disconnected.
I have also seen the message that the "bike is off, turn on to continue" as I am riding down the freeway.
Very delayed messages or whatever.

I've seen this where Energica just don't like the charge session being stopped by the charger for whatever reason.

After AC charging my Ribelle the pin only sometimes retract. So I have to push it down manually or power up the bike.
When manually interrupting the charging (AC or DC) by pressing the mode button, the pin always retracts.
-
I see this a lot, even though it says charge complete, the pin is still up holding the plug in place.
Im thinking maybe it's waiting for an 'Ok Im done too, its safe to unplug' or something from the charger as well before it disengages, for safety reasons? Not entirely sure on that.
You shouldn't really force it to let go, that's just asking for issues IMO. You force something, and it bends or breaks, now what?
Although it is a bit of a pain, just cycle power on the bike and it'll send a 'cycle' command to it to retract the locking mechanism so you can unplug properly.

The bike is waiting for the charger to tell if it is safe to let go of the plug? Interesting thought. Maybe I will try once what happens if I unplug the charger from the net first.
What confuses me is the fact that sometimes the pin is down and sometimes not. In the last dozen charges it was still up, regardless if I charge to 80 or 100 %.
-
Update: Disconnecting the charger from the outlet before unplugging from the bike does not change anything. The 'pin' stays up.
You have to push it manually down or switch on the bike for automatic retraction.
It's annoying. Some weeks ago this worked fine. Now not anymore.
-
It's quirky, I suspect some software bugs working at it as well. Although you can manually push the pin down, just my gut feeling, forcing stuff mechanically like that, is just inviting problems. When the pin bends slightly and wants to bind, or you snap the bastard off god forbid and now that little piece falls down into something etc etc. Take the extra 10 seconds and cycle the bikes power, this also ensures the bike 'SEES' that the charge is complete and pin retracted, to I guess you could call it, clean up it's own 'world view' of what's going on to maybe prevent some other errors if it thinks pin still up, whatever.
Without being actually able to see the code myself, it's hard to tell exactly what is going on, but by behaviors and what ive seen on other stuff in the past, pulling stuff out of my ass, (besides my head) that may have some credibility :).
I've dealt with many Ladder Logics, and SLC500, and Siemens PLC, and GE's horrendous MK V, VI VIe bla bla, Harmony, you name it and their accompanying .json .mkv .plc .m6b etc etc files to learn one thing over the years. You eventually learn to hate them ALL, you are convinced the designers of these systems, have already decided they hate YOU when they designed and coded this stuff!!
