Over regeneration error - battery still at 100% after 11% usage
blankets last edited by
Onewheel v1 gives me the Regeneration Alarm even after I've used 11% battery.
I've drained the battery to 0% and done an overnight charge, but this didn't help.
I've reinstalled the app, but this didn't help.
I commute the same route for work and haven't had this problem in the past.
When the app gives me the over regeneration alarm, my board actually will not shut off.
What's going on? Has this happened to anyone else? Is it a software bug and I should ignore the alarm and ride my board as usual? Or, is this a battery fault that would be covered under warranty?

I expirence the same problem. Almost like the calibration is off on the battery metering system. when riding with a group my board will report 100% a quarter into the ride while everyone else’s board is at 75%. My regeneration alarm goes off while riding on flat land for the 1st 5% when no one else’s does.
Planning on sending it in over the winter to have it looked at.

@blankets Same here too! I'm in talks with Future Motion about if I have to send my Plus back or not. My experence is you can ride it no problem you just have to deal with not knowing what is going on. Also, my board used to die at 22% or so now after I charged it for two days it dies at 7%. Theh hardest thing is that is dies too soon. That means I have to carry the board which has been happing more than I would like. I'll let you know what they say in regards to sending it back.
@blankets their battery reading system may be wanky. I don't have the same issue you're experiencing but when my boards (original and +) reach 1% I can still go at least a 1/2-mile- which is nice, but I don't really get why it's like that.

I'm in the same boat. I've noticed that the usage/regen % is usually about what right for what I would expect, it just requires doing some math in my head to figure out where I'm at. It's really hot these days (90+ degrees) and I wonder if that's why all of us are just now experiencing this? Maybe the battery sensor is heat sensitive? I haven't looked closely to see if the individual cells are accurate, though they all seem to be balanced. Hopefully someone will figure out a "fix" to this so we won't have to be without boards for awhile.

Has this been addressed by @Future-Motion ?

This is the biggest persistent problem I've had since passing 50 miles on the odo, battery regeneration alarm is useless, it just goes off continuously from minute 5 to minute 15 of my ride, every day. Percent still showed 100 even after I rode a whole mile today. Then suddenly it drops faster, and finally starts to read "true" AFAICT after about 30% is consumed. I know it's hard to measure lifepo3 battery consumption accurately on the 0-100% scale (especially at the low and high ends) so I wonder why the alarm at 99 is even a feature.
@readysetawesome today it got worse and the board started doing extreme pushback at15% then died for a nosedive very soon after. Ready for repair or replacement, what do I do besides send diagnostics?
@readysetawesome I think your options are somewhat limited . . . .
@groovyruvy yes there's simply no response on my 4 day old support ticket about it shrug and I can manage pretty well by monitoring cell voltage using the app.
@readysetawesome it really bugs me that sometimes they're hit-and-miss on their customer service. If you haven't already I'd suggest maybe following up with those guys on Monday, keep us posted.
I believe I managed to recalibrate the battery gauge by running the board down far enough to trigger pushback and then shutdown, waiting 5 minutes and doing it again - repeatedly - until it won't do anything when you step on.
Nope I spoke too soon.. reaching 0% had no affect on being stuck at 100% after the next recharge

I've improve my battery accuracy doin' that:
Charge the board with the cell phone app on .
Wait for the let's ride notification (don't wait for the green button on the charger).
Go for a big ride till the board need juice....charge till the app say let's ride...
That's how I do for the moment...
I'll see later for a complete charge to balance the cells ....

Yep, same here. Just listened to the regen warning go off for the first 15 mins of my commute. Do we think this is an app issue or a battery problem? My cells never all balance (~3.58 - 3.62v) even after 48hrs on the charger following a full drain.

Keep on this issue guys. My OW+ has the same problem. I go for a good 3 - 4 km's and the app still says the battery level is 100%. The level indicator does move down eventually but once it drops, it drops quickly making it as a power gauge pretty much useless. I have to monitor the distance traveled as a better indicator. I try to make sure I am back in the car or home by the time I hit the 10 km mark.
In the diagnostics section, the cell voltages are all declining properly. In fact when I go on a tandem ride, the newer OW+ (which has a linear battery gauge) voltage indicator drops down at about the same rate as the older OW+ that has the out-of-calibrated battery gauge.
I did a complete app delete and re-install where I had to reconnect my OW's. The battery gauge behaviour remained out of skew so my impression is that the mapping of cell voltages to a % remaining is done on the OW rather than the app. I can also confirm this notion by checking the battery indicator on my son's OW app. I suspect it will be the same.
I don't want to initiate a firmware board reset unless FM tell me to as my lifetime odometer may be cleared.
What should we do now? Sending my board back to FM is not my preferred option.

Hello@gadgetrider, lot of french rider had the same problem batterie gauge...
I stop charging my+ when '' let' s ride '' signal appears even if it's red !
Then the first km will be normal and at the end of the ride gauge seems normal... No 'need some juice' at 10/20or others incohérent %.

We are all in the same boat. I've had this issue for 3 months and the battery capacity has not been effected. I tried doing what @fabuz recommended above for a while but it also meant you had less than 100% range when you unplug early.
I've been charging until the charger light does turn green and riding for ~1 mile before going down large slopes. So far the board has never actually turned over from over regeneration despite the warnings.
I used to go exactly 1.8 miles before coming off 100% battery but that actually has increased to 2.9 miles. So I know my board is good for ~6 miles, from before this started, and now use the distance traveled to determine when I need a charge.
When the weather gets cold, I will send the board back to FM but until it works great, just thinks the battery is charged for way too long. I've tried 24, 36, 48 and 72 hour charge cycles, no change. So I've just accepted it.

So I've just accepted it.
That's it ! But I hope we get some words about it from FM...one day....
@hafeedgood your english spoken is so dope bro ! 😂😂😂

this is a pretty straightforward software bug, given the symptoms. I believe it is literally some mundane math error, since I can use 100 - (% used - % regen) as a perfectly accurate gauge of remaining battery while the app continues to show 100% for miles. The app (or the board) could do that same math, and often does so correctly I presume, but somewhere a bug is breaking it for many of us. The good news is that means it will IMO be fixed with firmware at some point, even if FM never actually acknowledges the obvious bug here.
