With the amount of tech going into automotive batteries, i feel this is where the forklift world will be heading, as they usually hang on the coat tails of the automotive world.
Forklifts and big heavy batteries are ideal bed fellows, with good battery ratios and correct battery maintenance and charging management, i feel it's all a bit of a gimmick.
The BYD truck is interesting, but if it's so good, why are none of the mainstream truck companies jumping on the bandwagon, this is not to do down BYD or the Chinese industry, but the industry is so close knit, i cannot see one manufacturer having an massive advantage over another for any significant length of time.
