These motors can reach up to 3 km/h when they are supplied by 7.2 V NiMH battery and and each motor has a stall torque of roughly 5 kg-cm (70 oz-in). Two compartments in the chassis has been designed to hold 7.2 V NiMH battery packs that are commonly used in RC cars. The interior of the chassis also features convenient screw terminals for connecting your battery and motor driver leads.
The motors are intended for a maximum nominal operating voltage of 7.2 V (2V minimum), and each has a stall current of 6.6 A and a no-load current of 420 mA at 7.2 V. This value can reach up to 18 A when it is changing its direction or stopped. We strongly recomend to use drivers can supply at least 20 A for each channel.
