Jack Rickard of EVTV has a Chinese copy of a Daihatsu van imported and converted in the US.
Called the "Vantage Green Van". Also uses Lead, Curtis and 72V.
The sheer weight of the lead batteries quickly wrecked the inner tread of the front tyres. He's now got proper lithium cells in it to lose the lard. It now does 100 miles at.... 25mph and is their regular workhorse to grab those crates of root beer and taking bits to and fro' for machining.
The first video includes when they obtained it.
The Second is more technical and useful for you.
The third video contains a bit of an update on the van.http://media.ev-tv.me/news052810-1280.movhttp://media2.ev-tv.me/news102210-1280.movhttp://media3.ev-tv.me/news020312-1280.mov
Hope its of some value.
