A quick Q for iSurgeon:

Did you use a preassembled 7-module pack like this one:

Or buy individual modules and make your own series pack?  What about the BMS they mention in the listing?

Yes that is basically what I bought , and that is who I bought it from but there is still skill required. It's not plug and play by any means.

Copy that, Tommy -

I totally get that we are not talking "plug and play" here.  The main things are: the form factor of the pack .... does it fit in the space? ;  the voltage and current delivery capability; and the interface with the existing Zero controller hardware/firmware/software.  I'm thinking particularly about the BMS here .......

This is all blue sky for me at the moment, looking ahead to the inevitable battery problems with a 2011 Zero S and trying to see a clear upgrade path.

Thanks,

Mike

Finally got mine up and running. Never got the old BMS to work again, but that was probably a failure of the BMS. I had a new BMS built, with 14 leads instead of 7, and it's working great, at least, on the riding side. There are voltage and chemistry differences between the stock battery and the new one, though, so I still need to reprogram the charger for the new stats. I'm definitely not getting a full charge with the current charger configuration. As soon as I start out, it drops down to around 60% on the gauge, right away, then runs down slowly to empty.

I've heard that you can get a laptop interface for connecting to the charger, which allows them to reprogram the charging rate and maximum voltage. Then you can download the software for the charger from the company and reprogram it. Need to find someone in the SF Bay area that can do that for me. Once that's done, the bike should be better than new.

did you ever get this figured out? I have a dead 2010DS I'd like to get fixed up.
