Re: [EVDL] Winter & EVs

Hello David,

These batteries first came with my EV, they were so tall, about 18 inches,
that they extended through the bottom of the floor pan and was inside the
aluminum cases. At very low temperatures, I had to add another inch of
insulation over these boxes.

These batteries really would jerk my EV which weigh about 7850 lbs up to 60
mph at no time. Pulling this car at 60 mph cruse, the battery ampere was at
about 180 amps at 180 volts. These batteries last me 10 years to 1985.

I wanted to have a shorter battery that did not stick below the EV, so I
place Exides X220 or I think there were X235's that still got me another 10
years. I was no longer have to pull that hill any longer.

They do have shorter battery packs now in 42 volt packs that are in a
fiberglass case. These runs about $100.00 a cell. As for the fuel cell
which is a alkaline fuel cell, not the PEM hydrogen type that everybody is
getting bent out shape for.

It also can use natural gas or propane for use as a standby power units. It
can be fuel with anhydrous ammonia that I can get from a agriculture supply
company that's up the road from me.
