Running a battery to zero, should not hurt a thing.  Should be put on charger right away.  Programming protects it.

I tried running mine to zero and recharging it but that didnt seem to change anything. Funny thing is I hit zero percent on the dash and still had the same get up and go as it did with the battery fully charged, even drove a another mile home but didnt change anything. I did take screen shots of the different states of charge so I could recall the voltage. Does the voltage look correct for 0% and 100% SOC?

You would have to actually ride it, discharging all the way and see what kind of capacity you get and what the balance is. Preferably more than once since the bike recalibrates itself under a certain level of discharge. You can install your own power meter like a cycle analyst to really fine-grain analyze your battery capacity.

Anything else is just guessing. That's probably not the answer you want to hear, but the batteries are pretty reliable if not allowed to fully drain.

I think I may have to do this. I use to get about 1 mile per percent of battery. I went in for the last firmware update and ever since then I now only get 30 miles for 50% battery. It does not really matter if I am in eco, sport, or custom mode it is always the same. This is a 2014 DS with only about 1200 miles on it.

Sorry guys it took so long to get picture, just got busy this weekend. As far as selling the bars themselves, sure make an offer.

Police crash bars, intercomm, and wiring for the lights and intercomm off of a 2014 DS11.4. I bought the bike with 700 miles on it and it came with the police setup. I removed it still in very nice condition. Looks like the police version were about $500 new I am willing to let them go for $250 everything listed plus shipping.

God afternoon,
 I purchased a used zero about 3 months ago and it says it needs firmware update. Its a 2014 so I have to go to the dealer to get it done. Do you know if the dealer charges for the firmware update?
Thanks,

Thank you all for your help. I bit the bullet and bought the masterpiece in pieces. I actually looked at it today and stared with what you see in the pics .By the end of the day I was riding it down the street.  The previous owner stripped the weave off the harness and gave the harness to me in a box I was able to figure out 95% of it, now I have to clean up the harness and put the body back on it. Battery was 85% charged after sitting a year and all the electronics work.
Thanks again

I will have to see when I get there, so far this is sight unseen. The owner told me he disassembled the motorcycle in hopes of using the electronics for another project, then realized that it is too late in life to finish his project so he put everything on a pallet (includes everything to reassemble the motorcycle). As far as putting it back together, I am not worried as I have been a motorcycle tech for over 16 years and for the last 8 years an instructor for the electrical classes at MMI. What I am worried about is the battery. The owner said he fully charged it and then left it sit. Well lithium does not like to be left full charge. I know that the bike itself would slowly discharge which would be good as long as it doesnt drop below 30%, but with the battery out of the bike I am not sure it can self discharge well enough to get away from full charge unless the BMS is hooked to it. From what I have read the BMS is in the battery pack so it might be alright. As far as hooking it up and looking at the logs, I am not sure the cables are long enough to make it to the plug without reinstalling the battery first. Although I have been a mechanic and instructor for awhile it is mostly ICE bikes and the normal 12V systems on those bikes.I have taken EV classes over this last year on the technology side, but thats only larger scale car EV, not motorcycles.
Well enough blabbering, thanks guys. Ill do more research to see if I can find a simple way to check it. I have notice you can not find a service manual for the zero motorcycles, with the exception of the unofficial service manual. Unless one of you have access to one?
