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.

Thanks

I found non ( no ul cert)grid tie pannels thin film , for $.99/watt 1400 watts will get 10,000 miles/year with out losses. used forklift batteries , big ups batteries used , used ups sine wave inverter 3to 5kw $200 , new charge controller $500 (Outback). 1400 watts/hr.X5.9 hours / day avarge (north cal ) X 280 days per year = 2,312,800 watt hrs. / year ( 2.3 mega watts/year)

I have serious doubts about that. FLA batteries energy density are around 30 to 50 wh/kg. So how much does each battery weigh? 32 volt @ 650 AH they would have to weigh at least 420 Kg or 920 pounds each @ at the extreme high end of energy density of 50 wh/kg.

I believe you said they weigh 325 pounds each or 147 Kg. If they are 32 volt @ 650 AH would be a density of 140 wh/kg. So you are telling us a FLA has a higher energy density than LFP of 100 wh/kg? I seriously doubt that.

I am familiar with RR 32 volt batteries and Rolls Surrette makes a 32 volt 660 AH battery but it weighs in at 1240 pounds or 37 wh/kg. You must be seriously mistaken with either the weight or AH capacity
how many cells / battery ? 6 cells= 12 volts I have a old forklift battery 2000+ lbs , 24 volts , 2000 amp hr. 48kwh if new ( or .048 mega watts LOL)
