This is a no batteries (NB) kit which does not include the batteries and battery charger.
The two gear motors in this kit have clockwise shaft rotation and should be used with clockwise shaft rotation for best performance. When these gear motors are run counterclockwise their shaft speed will be slower then when run clockwise, so we recommend installing both motors so they run clockwise when the vehicle is moving forward.
This kit contains 2 quantity of HNS-137, 2 quantity of MOT-36600G, 2 quantity of SPD-361000B, and one quantity of everything else.
