The reason I did not include the verbal quote is that it was verbal...I
heard them quote different numbers - higher - to others..Why, I do not know.
The EV cell was quoted at $6.50 - in units of 3,000
Around the corner PHET quoted between $4.40 and $4.80 for their cells
BUNDLED in the Prismatic Battery pack....I am still curious about the
effects of the internal wiring and fusing on the performance of the bundles.
How much resistance is added when EACH cell has a fuse? If the performance
is unaffected this seems like a terrific product.

sigh, why not say what they told you??? it's this kind of obtuseness we
are fighting and you take part in it. noone asked you to keep secrets,
you just go there as the first thing you do.. Jesus Christ!

You (as an Individual) can't legally convert a car to run on Natural Gas
(or techincally any fuel other than the one it was designed for).
In fact the only legal conversion is to battery power (with the exception
of one state), or to other fuels as long as the engine is unmodified and
can still run on it's orignal fuel.
This is a Federal statute and deals with emissions controls. Apparently
they were having problems with folks converting to CNG and propane and
ending up producing much more pollution than the car originally did.
FWIW one state (minnisota?) requires electric conversions be done by
licensed converters.
So your options are a pure EV or perhaps a diesel running biodiesel. Or
you can purchase a car designed to run on CNG or propane or one converted
by a certified converter.

Ooooooo, cylindrical------that reminds me of the good old days when Killacycle
was powered by the old D-cell looking cells (Boulder cells?) in PVC pipe and it
looked like it was a bike bomb at Woodburn....

Wow, I had not heard of LionEV, but those prices are... reasonable.
With Thunder Sky cells going for $2/Ah ($625/KWh, no BMS) and LionEV
cells for $510/KWh (including BMS!!), I wonder why anyone is talking
about Thunder Sky at all.
If I can truly get 2000 cycles on a 20KWh pack for $12K, my plans might
be back on the table. If my cycles are 50 miles, that's 12 cents per
mile. But 50 miles would not be 100% DOD (unless it's at a constant
70mph), so a pack should get much more than that. I'm spending 8 cents
per mile for gasoline right now, and that's not looking to go down.
So... Thanks for the link.
