Batteries are of sealed type and can't leak if tipped. Now the batteries charge, not the kart. A kart can be driven while a spare battery is charging. The electrics are on a removable circuit board which can be shipped back to the factory in case service is needed. The governor is determined with key, not operator adjustment.
Parents decide top speed by which key they give to the operator.
Each child can have their own key. Accelerator cable is eliminated for dependability. To prevent overheating from improper use, a thermoswitch is now installed inside the motor. Kango LLC 2258 Barnes Ferry Rd.
