JamaraJamara405027 40 MHz 1:14 Scale, Black BMW i8 Battery Pack Deluxe Car with Manual Door

You get a lot for your money (I paid a little over £12 delivered):- Headlights when accelerating fowards- Breaklights when accelerating backwards- Internal rechargeable battery (600mA, 4.8V, NiMH), recharged via USB- Nicely modelled car.- centrifugal clutch for front wheel steering- rear differential*HOWEVER*, this car is clearly designed to operate using 5xAA.5xAA will deliver anywhere between 7.5V and 6V, depending on battery level.Thus the 4.8V delivered by the car's rechargeable battery is completely inadequate, and manifests as two serious faults:1) The car has pathetic acceleration2) There is insufficient power delivered into the centrifugal clutch, meaning the front steering is barely functional.It's such a shame that this car's electrics were clearly designed on a shoe-string budget, as the car itself looks great and the mechanical components are sound.
