But anyways, off to search for forklift motors.

I'm just another guy like you, dreaming of a conversion down the road, so, I'm not talking from experience here. But, I have to say, from examining battery specs., comparing prices and reading lots, I have to agree with MPaulHolmes on the batteries. Every time I run the numbers, lead seems to come out the most expensive in the long run and LFP's the cheapest. You have to factor in cycle life and that a lead acid pack has to be larger to store the same energy. Lead is cheaper up front, but lithium is cheaper $/mile. If you spend all that money on lead and it doesn't do what you want it to, your wife may shut you down for good.

Almost all my driving is done 1-5 miles at a time.
Best short trip: 2.4 l/100 km, 3.9 km
