Locomotive Batteries?

Hello everyone,
I've been researching and planning an EV for sometime now. I have a 26 mile one way commute to work, with some pretty big hills and a 60mph speed limit. I'm looking at something that will do 50mph and get about 30-40 mile range.

As for batteries, I have access to a bunch of old 32v locomotive batteries. They are very heavy, about 325lbs each. But I plan on a 96v system, so I only need 3. 1000lbs is a lot to add to a vehicle, so I'm looking at a small/medium size truck. With the engine pulled, it might not be so bad. I've found an old postal jeep for $200, everything is there and it is pretty bare bones to start with. Not sure it will handle the weight.

First, does anyone know if these batteries would be worth the weight? I'm sure I would probably get good mileage because of the reserve amps in these things. Also, they would help with the amps needed to pull these hills. They are designed to provide 400 amps when starting the locomotive.

Any thoughts? I'll take some pictures of them today.

hard to say how worthwhile the batteries are without more information. Some very large batteries are very worthless, while some are a goldmine. The 1000lbs by itself is not that unusual; with my ten 12v 75 ah batteries I'm looking at adding about 600 lbs. 150 Ah, which is what I would really like (but these were free) would be ~ 850 lbs. So don't worry about that too much; but you should check the GVWR and make sure that you're not too far over. You can anticipate taking something like 300-400 lbs out, depending on the size of the engine. If curb weight - engine weight + battery weight is < GVWR, you're good to go.
