Calculating Watt Hours For Your Electric Skateboard

How To Convert mAh to Wh

To calculate mAh (Milli-Amp Hours) to Wh (Watt Hours) will give you a more definite idea of how much battery capacity and power your setup will have. milliampere-hours x volts / 1000 = watt-hours or mAh x V / 1000 = Wh

Example for 6S 5000mah converted to Wh

A 6S 5000mah lipo pack with a 3.7v nominal. To calculate the Wh - we would use the voltage 3.7v x 6s = 22.2v 5000mah x 22.2v / 1000 = Wh A 6S 5000mah lipo pack is 111 Watt Hours.

Example for 13S 8800mah converted to Wh

A 13S 8800mah lipo pack with a 3.7v nominal. To calculate the Wh - we would use the voltage 3.7v x 13s = 48.1v 8800mah x 48.1v / 1000 = Wh A 13S 8800mah lipo pack is 423.28 Watt Hours.

    Does this directly translate into ride time? 111 Watt hours at a current rate or just in general? My setup right now is 2 3S batteries in series. Each are rated at 5500 mAh and are pushing a 6364 turnigy motor. However, I am only experiencing about 15 – 20 minutes of ride time before cell voltage reaches about 3.8. Is this normal?
