We are successfully testing our LiFeUP batteries at CPS s.r.o. in special motorized cart determined to easily move with parked helicopters. The helimovers are working with 24V/60Ah battery packs, which should provide enough energy for trouble-free operation for several weeks. LTW Cells have enough power to move with Robinson 22 and Robinson 44 helicopters. If you are interested in similar mover for your own usage, please contact us.
