I have a British sports car from the 'microcar' era after the war-- a 1959
Berkeley SE 328 (the size of the orig. motor-- 328 cc!) Google 'Berkeley 328'
or 392 in google pics-- very aerodynamic, an ideal small project. They came
with an 18 hpo 2-stroke motorcycle motor, and were only capable of about 65mph.
Later Berkeley provided a Royal Enfield motor, getting them up over 100 max
speed. The first Berks weighed under 700 pounds from the factory (late ones
about 750), so, stripped of the mc engine and tank, and the transmission , my
project will start at about 500 lb-- plus batteries and motor/controller-- and
eventually the driver-- me at 160 more. I bought a Berk that had been converted
to electric with NiCad batteries in the late 90s (one of the group, "Team New
England" worked for NASA, had access to cheap ones), which they raced in the
'Tour de Sol-- a New England race that ran for several years. The Berkeley beat
all comers in the autocross,
and won the entire 7-day event one year. So I'm aiming to get it back on the
road. It has a new 144v Solectria ac motor and Solectria controller-- part of
the purchase deal.
SO, my Q: If it were your project and you were opting for lightweight
batteries, what chemistry would you chose-- I gather there are two different
Lithium chemistries (or any other chemistry the list members can steer me to.).
I won't say price is no object, but I'm prepared to put upwards of 5 grand
into the batts. There is a size limitation, so I will go for the max
ampere-hours I can fit in-- into the car or into my budget. ALSO: within a
given chemistry, what brand of battery seems to have a superior record? Any
and all information and opinions welcome! Thx, Chris in Northern VA
