My 2020 Zero FXS  SOC is at 54% right now.  It's 55F degrees in my garage.  I'll check again in a few days.

Hi Valnar, thanks for your input, I am curious about your finding afterwards

[valnar]

It's been 72 hours exactly and my SOC settled at 53%. I think it was at 54% for a while, so I'd call that less than 1% in 3 days.  Similar temperatures each day.


Edit: I just reread this post.

Hi, I have also a FXS2020, I have witnessed the same about 1% discharging a day. But as a remark I have also seen that this discharging rate is slowing down below 60% of load to about 1% every 3 days?

Mine falls into that category, so I'll check again in a few days.  I'd rather not bump it up to 90% again since my riding season is over though.

It is an interesting observation, thanks for sharing.  Mine discharges faster, but it is still at the dealer, so I will have the opportunity to make new observations once it is back. It will be probably a month or two, before I have it home.

[valnar]

Feel free to use me or anyone else in this forum to show that excessive drain is not normal.  I can send my logs, if it helps.

Good luck.

[sharagan]

thanks for the offer, I will come back to you, if somebody tries to tell me that it is normal

[valnar]

Today it was still at 53%, three days later.

[sharagan]

Consider yourself lucky, that is my goal
Please check again in a week and let me know, thanks.

The weather is getting warmer so I'm going to charge & go riding.  It was still at 53%.

Edit:
Correction.  I did not have time to ride yesterday.  Today however, I turned it on and it was at 47%.  I started riding and it dropped fairly fast to 41%, then seemed to drop normally after that.  That was weird.  So maybe it just depends on the SOC, your blood type, moon phase and President-elect.  Who knows.

Hi Valnar, so it seems that you have 6-10%of discharge in 10 days depending on the fact if the drop after you started riding was due to the weather and your usage or the bike just corrected the reading. Could it be that the bike in its off state is not really off and consumes a fair amount of energy? The manual says, that the bike goes to long term storage mode after 30 days of not turning it on. I`m starting to have the feeling that this is either a design flaw or a normal characteristic of the bike. It would be a bit of a disadvantage as we have to keep it above 30% to avoid damage to the battery, but my main concern is if I have a defective bike or not. Thanks again for your observations

[valnar]

I have only owned this bike over one Winter, which was this past year.  I don't recall it ever going down that fast, but it could be my memory.

I'll charge it up to 70% when the snow finally falls and keep an eye on it.

My SRF is parked in a non heated but well insulated garage and does around -1% a day at max. Often less.

[sharagan]

Hi Hans, could you please check how much it loses over the course of 10 days?

My bike so far (still at the dealer) was charged to 100% for observation purposes roughly in the mid of October, I was there to check on it on Nov 10th and the battery had 60%, so from that I suspect that the discharge is faster with a higher SOC.

[Hans2183]

For 5 days I lost 2% going from 66% SOC to 64%

[sharagan]

Just a small update from my side. I received an email from Zero to my inquiry, that the decrease in SOC of 1% per day is not normal. The dealer did some troubleshooting on the software side, charged it up and they monitor it. I will know more next week. I will get it back if everything checks out fine. Will report back, once I hear from them.
