producției line.

-batts of 2016 all are at least Ref.AJ or higher.
-611 is over daily capacity.

Maybe is only a simulation, or your tool not retrive correct data from BCM.
Just an error in my math when I was working on the initial code. I've been working on the project on and off since November. The local Segway dealer here in Austin went out of business, so my access to batteries has become more limited.

I do have one good working battery on my workbench, and I need a little more time in the lab to finish a basic working tool to simply read all the cell voltages, serial number, etc.

Thanks to Segway Nation here in Austin, I once again have access to good and red-light batteries, and development continues. I now have Rev AF, AH batteries, and am trying to get my hands on a NiMH battery that still works.

I have updated the pinout on the GitHub image, and am working on weekends to make a breadboard and basic 2-layer gerber/drill file set you can send to 4PCB, ExpressPCB, OSHpark ( etc ) to make an arduino "shield"

I also now have a working 3D STL file so that you can get a connector printed and not have to find the rather hard to get one, and so that you can connect to the battery without having to resort to testing clips.

( It's for development and testing, not for high-current application! Don't use it if you're going to be drawing full voltage from the cell or to charge the cell )

Thanks for your patience Y'all!

For those starting hacking on the cell -- first available i2c bus device is at address 0x31.
