Are you looking for a BATTERY for XU/X/MX 2009 2010 2011?
« on: December 12, 2013, 01:02:34 PM »

Having dead 2kWh zero battery? Looking for a working  and great shape replacement battery?

I'm your man!.. These battery are becoming very rare and difficult to get even with Zero themself so i decided that it's time to make something of my (like new) 4kWh DS 2010 battery !

I am rebuilding two 2kWh battery compatible with for 2009-2011 X, XU or MX.

I got two deffective 2kWh  battery with low cells that i'm rebuilding with original great shape cells coming from a perfect shape 4kWh DS 2010 battery of 2300km  ( like new).

Let me know if you are looking for a like new 100% working battery very close to original capacity.

I'm looking for about 950$ each. Labor on each battery is about 20-25hours of dissassembly and testing and reassembly.

Yes i will post it in the item for sale as well..

Doc

Zero does rebuild the older packs, but I don't think they handle very many of them. What a great community service : )

Since I have not been able to sell my 2010 DS for $2K, I've been thinking I should do something with the battery. It has very little usage and I've always kept it plugged in so it hasn't self discharged. Too bad you are way up there in Canada, Doc.

Doc , might help if you add "Are you" to the start of the forum title.
It read like you are asking for those batteries instead of you wanting to sell them.

Enjoy reading about your projects and the knowledge you share.

interesting work. When you talk about the original capacity, I'm wondering, what real capacity is the experience. I've a 2011 XU, and whatever I do, the max charge I measured was 1.6 kWh, whereby typically when I ride the bike to a level where the engine stops, the battery charge is then in the range of 1.5kWh, and I wonder, if this is really the full capacity of a 2kWh battery, or if something is broken. Is there any experience on this, or a simple method to test, if the battery is fine?

2011 XU was rated at 2.0 kWh maximum capacity, which is a ****** stupid metric. This is calculated in the following way:

14 cells in series * 4.2 volts/cell = 58.8 volts maximum

34 Ah (approx) * 58.8 volts maximum = 1999 Wh

You will never be able to store or draw 2 kWh out of Zero's "2 kWh" "maximum capacity" modules.

As new, in the real world you could expect to get something closer to the nominal capacity out of the battery, which is around 14 series * 3.7 volts/cell * 34 Ah = 1.76 kWh. Probably less, as typically the cell nominal capacity rating is at a C/2 or C/3 discharge rate, and your average discharge is probably closer to 2C.

1.6 kWh to charge and 1.5 kWh discharged from a 2011 battery sounds relatively healthy to me.

Doc,

     Do you have any of these batteries left?  I have a 2011 Zero X and wouldn't mind having a spare.

What cells are you using? The old Molicel, or the new EIG?

I just picked up a 2010 Zero S . The battery pack is dead. Do you have any more rebuilt packs?

Thanks

What country are you in?
Have you measured the voltage of the battery yet to see what it is?
What is the history of the bike?

I'm in the US.

The voltage is 0. The pack has been dead for about 3 years. It's just been sitting in some guys garage, unplugged, since early 2012.

I just picked the bike up over the weekend.

The problem you will have is putting more cells in than there are wires for the bms so there is effectively no way for the extra cells to be monitored or charged. Either you will have to fool the bms some way or use you own bms. If you take the zero bms out then you will have to ensure the rest of the bike runs without it too.
