Thanks for the great forum! Lots of useful information.
I hope to contribute.
Recently picked up a 2010 S
The battery has not been plugged in, voltage is 39v. I have the battery out and apart, will begin by charging with my RC charger.
It didn't come with a charger, can someone recommend an inexpensive one?

Where are you located
Should have built in charger

Unfortunately it did not

Sorry to say but it is unlikely that you will be able to recover the battery when it is at 39VDC.
The best you can try is measure each battery pack voltage and try to directly charge those that are lowest.
Balance (evenly charged packs) is very important.
Each pack of batteries should be about 7.2 to 7.6 VDC.
If any are under 4 volts it is mostly likely OEL (end of life).
You can try calling Zero support to see if they would rebuid your battery.
If possible this would run about $2500 - $3000.
The charger used on these was the Delta Q configured for (IIRC) 60VDC max.
These are not inexpensive and would be a waste of money if your battery is no good.
These chargers are mounted under the bike on the 2010 model S.
Good Luck.
Word to the wise...
Before purchasing ANY older electric bike please verify the pack voltage before making the purchase.
The biggest single cost on these vehicles is the battery.
The biggest cause of battery failure is improper maintenance habits.
Especially long term off charge with a low SOC (state of charge).

I've read of the same pack recovering after being down to 37V. I don't mind replacing cells if/when found to be unrecoverable.
The components are worth what I have in it and I like to build motorcycles! However this is my first electric intended to carry a human.
Here's a bike I put together a Ninja 650 with suspension from a KTM. Plenty of power and suspension. I was out on a week long camping trip in this pic somewhere near Cheaha Mtn.

Wow that looks pretty cool, you should start a build thread on ADV RIDER, not being sarcastic, I would love to see what the build was like!

Ahh grasshopper, ask and you shall receive.

Great, awesome build! Read the full version, now I just have to explain to the boss what I've been doing for the last while

Well at least you didn't nod off. And he likely already knows where you've been and how long you've been there!
Anyone know the rated capacity of the 2010 zero s battery? Documentation is seriouly lacking on the 2010s!
And I've come up with a short term charging solution, hooked up a couple of my bench top power supplies in series :) sad thing is I'll max out at 3a, hopefully I don't grow old while it charges ???

I just did a google search and came up with the spec's 58V 70Ah 4kW, but that is peak.
Looks very similar to the 2011 S battery box. if so then you could probably re-pack it with 7 Nissan Leaf battery modules to get 14s2p and 66Ah peak, that's if you can't revive the original battery.

Doctorbass did have a heap of Zero parts or sale, including chargers, in this post here http://electricmotorcycleforum.com/boards/index.php?topic=2989.msg24428#msg24428 (http://electricmotorcycleforum.com/boards/index.php?topic=2989.msg24428#msg24428)

Thanks for the suggestions. Still trying to revive the battery.
Those leaf modules look interesting.
Whats the worse case range on a stock 2010, theoretically speaking, you know, uphill both ways, overweight rider, 30mph headwind, battery in operating condition.
I'll be riding it in the dirt mostly. Is a 12 mile round trip to the post office a realistic first goal?
-
I just replaced my battery with 7 leaf cells and I commute 15 miles one way at mostly 45-55mph and weight 165. I made it no problem even on the original battery albeit with the motor controller groaning from voltage sag. I think I could probably make it both ways on a charge but I still charge at work.
Driving off road at presumably lower speeds you'll use much less power per mile. I've seen on my cycle analyst as little as 1 amp hour per mile while going 25mph and as much as 2 ah per mile driving fast 60-70mph and accelerating fast every chance i get.
