Here is another informative article about the KillaCycle:

Be sure to watch the video clip. :)

I don't know if this has ever been covered fully but how many cells are
in the pack? and how many in series?
and what does it cost?

Current pack: 990 cells. 110 in series, 9 in
parallel. Previous pack: 880 cells. 110 in series, 8
in parallel. A refined pack design along with frame
modification allowed for more cells. As far as cost
to acquire the cells, not much at all in terms of
dollars due to sponsorship. BUT... no one gives away
sponsorship. You have to work very hard to earn it.
Just ask John Wayland (from what little I know about
what it takes to earn sponsorship, he's the king; I
don't know of anyone else who works harder to earn
sponsorhip). There is still a lot more to building a
pack. Like testing the limits of the cells,
developing assembly techniques, learning how to weld
tabs, acquiring (and getting functional) a tab welder,
_LOTS_ of tabs, etc. I am not 100% sure how many tabs
there are, but approximatly, there are two tabs
(paralleled) between every cell in series, and one tab
connecting each parallel cell. There is the effort
involved in figuring out how much current a battery
with only one tab can put out, and how to work around
that limitation. (A single tab conducting much over
100A will overheat and cause damage to the cell). Oh,
yea, then there's the BMS, 1000+ hours all by
itself... I'm not a very good writer, but hopefully
you can get a sense of the effort involved.

Sorry to be dumb, but is it 9 strings of 110 cells? Or is it 9 cells to a pack, 110 packs in
series?

Is the BMS at a cell level? Has there been any attempt to see how the idividual cells are doing?
Have there been enough cycles to see if cell voltages are starting to wander?

Longing for lithium in CT,

The video doesn't appear to be available on this site. Does anyone have the direct Google Video Link.
