Well.......
I believe lithium is now about twice the price of lead for similar
energy storage capacity. That's a WAG but think I've seen Leaf and Volt
modules around that price. The lithium should last about 5 times as
long. Lithium has far less maintenance than lead. Lithium gives you a
larger fraction of stored energy, ~80% vs ~50%.
I think that makes lithium FAR cheaper than lead.
Is the C-Car 48v? You'd be looking at ~$800 worth of lead? Somebody
estimate how much Leaf battery that you buy you.
Answering my own question:

Six of those in series would give you about 3kwh and about 48vdc and
cost less than $800 before shipping. That's only a ~50 pound battery so
you would really want to put 2-4 sets of those in a golf cart type
vehicle. But, a single set would supply 240a which should be plenty for
a golf cart.
