Is this Andrew from the chassis list?
thanks for the links and info!
I just found a Chinese cheap and quiet propane generator, and I am
thinking of making a hybrid, with a view to hydrogen conversion later on.
Also there are some Lithiums at about $1 ea for a 3.3V 850 mah cell on a
surplus site. Lets see that would be about 40 cells to get a 120V+ pack,
at $40, then 18 packs to get about 16A at $720
Did I do that right?
Assuming the Lithiums are OK and can be made into packs etc etc.

John,
Enersys batteries are great for taking abuse, and high energy, as
Garret mentioned. You can also charge them extremely fast.
Here are some links (bottom of page) to sources:

A less expensive alternative is to use B&B Batteries. The "EVP" and
"EB" series work well for EVs.

NiMH and NiCad cells would work too, depending on the discharge rate.
D Cells are the cheapest for energy storage. Known sources for cheap
cells:

Beware that the D-Cells available from the above sources appear to
have high internal resistances, and may not provide much power in a
large pack. It may be best to use a hybrid pack in that instance where
a small lead-acid pack provides most of the power, using the
NiMH/NiCad pack to augment the energy storage, and "feed" the
lead-acid pack.
SAFT are probably the best quality NiMH/NiCad available. Known source:

Good luck,
