You should also look at Caterpillar/Mitsi.
The 48 volt N series AC trucks are excellent in both performance and reliabilty. Streets ahead of the previous DC model.
They have also just introduced AC to the 24volt models using the same system. Just be sure with 24volt trucks that the battery capacity is going to be sufficent as they are really only good for a few hours a day.
This applies no matter what the make.
