The first great feature is that the batteries are no longer bolted individually into the kart. We designed the battery packs with carrying handles so they can be unplugged, unstrapped, and swapped for a charged pack in less than a minute without tools. The batteries in the pack are also sealed, maintennance free batteries to prevent corrosion and leakage. The E Star is rated for 16 to 20 miles battery range for each charge with a 60 lb. rider. The E Star will carry riders up to 300 lb.
Range is lower with more weight, understandably.
This 1WD E Star kart is the best for all around yard and pavement use. For field or off road use we recommend that you purchase the E Star Live instead. New with the E Star is a better way of limiting the speed of the kart. Our previous K karts had a multiposition switch hidden on the kart for this purpose. Only, when kids saw how parents adjusted the speed, they could make their own adjustments when they were alone.
