Zero should soon be putting battery voltage on the riding screen for the app I hope, as it is the ONLY metric you can trust when it comes to range left.  Amp Hours, Kwh remaining, range, distance to empty, SOC all rely on the current sensors and coulomb counting.

While I agree it should be an option, don't forget that most people are not familiar with basic electrical principles, never mind technical EV knowledge.

Alot of them will be confused when the voltage goes up after they stop, or goes down when they turn onto the highway... Sure we understand it, and it seems so simple... but until the average high school kid knows  basic electrical principles, the general public are better off letting a watt meter do it for them.

Assuming that's true.....what better way to make sure that stays true than to hide the information from the rider.  Thinking that people can't figure out how voltage works if it's staring them in the face every time they ride is a little insulting to the intelligence of the general public.

I'll be updating the manual entry for SoC based on the explanations here:

But also I'll try to describe the existing cutbacks described; just not sure how I'll structure it.

Reference point: 2016SR, ~5K miles, SOC at start of ride was 90%.  Rode combination of highway/city. The last leg was highway, 70 - 85mph. I was pushing the bike, to see what it did at low SOC. I got home with 3%. Anecdotal results: it seemed like when SOC got low (< 10%) acceleration was limited; but that may be my imagination. My top speed was definitely not limited. Summary: the bike performed flawlessly, I've no complaints.

Compared to some other's reports, I'm thinking I may have lucked out with a really good machine. BTW, had software update/recomissioning a few weeks ago. I think I'm one software update behind.

Last week when I was riding, I didn't notice a limp mode until about 10% battery life. I was in Eco mode and on the twisties. There was a little incline as well. I've hit 0% before and was able to go another 3-5 miles but never on an incline.

If it sounds insulting, then you're not the general public. The general public will make no attempt to learn, and instead will clog up tech support with 500 calls of day wanting to know why the voltage drops when riding and how is the bike "magically charging at stop lights"...

If you really want a voltmeter, you could connect one to either the charge port, or directly to the controller lugs.

This is perhaps true, if a 2-3 sentence explanation of voltage display wasn't included as a pop up screen when voltage is displayed as "advanced" options with a proper warning.  Thinking some people are too dumb to understand that is not a valid reason to hide useful information from the majority of riders to where it can make their user experience more useful and reliable.

A morning a couple months ago I left the house with 45% on my iPhone 6S Plus (fell asleep using the phone and forgot to plug in), went to the dog beach on a brisk cold morning ride, the phone mounted and got chilled right away from its 74 degree environment to about 38 degrees.  Got to the beach and tried to take a video of Charger playing with another dog.  It recorded for about 7 seconds and then the phone died and wouldn't turn back on.  Got home and plugged the phone in and when it came on it instantly said 37% and charging.

Some might consider Apple a big company, and even the big boys don't have it completely figured out yet.

You'll notice that your Apple phone does not have a voltmeter either, for the same reason.

Does anyone know if dealers will or can downgrade the firmware if a customers so desires?

I hit limp mode today at 19% and it was a harrowing experience. I'd only gone about 61 miles at that point off highway probably averaging about 48 mph. Wasn't especially hot out. I've hit it before in the high teens (battery percentage) and I believe that time was also after my last firmware upgrade (same version I have now).

Indeed. This post inpsired me to write about my voltmeter addition.
