and if you wanted, it is possible to set up most ev100 trucks like that too, In my opinion, it's just that regen was so new, most customers wanted it to be just like an IC car, with plenty of coast, and since all their other electric forklifts coasted, we always set it up for what the customer wanted.
Regen does not add jack snot to the battery shift life, all it really does is extend the life of the brake shoes.
