the big problem for now is know the best battery model and controller; must be compatible with EV but also with solar panels. I was thinking put about 80 OpzV batteries on the chassi, but yet many variables on the way.
well, my dears, while many EV users worry on find a charge point to plug his vehicle and complete the battery level, I simply search for a free area 8x8m (this is lenght x wide when opened), put a Pink Floyd and wait... wow, work time, I will work in my next book "The Parallel Army" science fiction.
