We recommend big power motor to choose big capacity battery, for example: For 200W,250W and 350W motor kits, we recommend to use 10AH or 12AH Batteries, for 500W and 750W motor kits, we recommend to use 15AH,20AH Batteries. For 1000W motor kits, we recommend to use 20AH or above Batteries.

5. How to calculate torque?
Torque (in N*m) = 9.55 * Power (in watts) / Speed (in rpm)
1N*m = 141.61 oz*in = 8.85 lb*in = 10,200.0 g*cm, 1.0 hp = 745.7 watts
1.0 in = 2.54 cm, 1.0 kg = 2.205 lb = 35.27 oz, 1.0 mile = 1.61 Km, Tc=(Tf-32)*5/9.
