The Movexx T1500D takes away the manual effort required to push trolleys. It has both variable speed and an overriding dual speed button. A built-in smart control unit is programmable for speed, acceleration and braking, plus numerous other fine tune adjustments. A fast and easy-to-remove Lithium battery system allows opportunity charging plus constant use of the Movexx T1500D when optional additional batteries are included. Additional batteries can be kept on an external charger, so they are ready for use once the battery indicator shines red. Many other options are also available. Towing hitches are not included.
