I'm charging my new to me '15 SR fully for a first time today and I am confused as to when it is "done" charging.
- it says 100% on the dash
- the 4 BMS LEDs flash once periodically, which according the manual means charge complete
- the green indicator on the dash blinks slowly, which per the manual means it is still charging (should be solid when done)
So is it fully charged or is it still charging?
Thanks!

It's just balancing the cells. This minimizes any stress later and extends the life of the battery. You don't have to do it on every charge, but Zero recommends leaving the bike plugged in when you can for this reason.
-
In short, it's charged enough for you to consider it 100% if you wanted to go riding, but it's still actively charging the cells that are "behind" for whatever reason.
You can still unplug the bike at any time and go riding; cell balancing is just good battery maintenance that the charger is always doing at the end of a charge (and occasionally when sitting for a while).

Thanks! I was expecting some indication that balancing is going on...

Fire up the app. It will tell you when charging current drops dramatically, and cell voltage begins (and finishes) equalizing. All the charging information you could need is on the app.

Yup, just paired the bike with the phone. 2-4mV imbalance at 100% SoC, which seems good to me.
What troubles me though, is that it still seems to be charging at full power at up to 13A, even though it is at 100% SoC. Shouldn't it be reducing power at this point? 117V pack voltage?
Edit: looks like it stopped the charge. Voltage dropped to 116V. Solid green on screen, app concurs...
