If you know the battery capacity of an electric skateboard in Watt-hours (Wh), you can get a rough estimate of how far the board can carry you. Here’s how.
Step 1
Use this chart to get a rough estimate of a board’s efficiency (Wh/km) based on your weight. If you don’t like charts, use this table instead:
| Rider weight (kg) | Longboards (Wh/km) | All-terrain (Wh/km) |
|---|---|---|
| 60 | 8 | 12 |
| 70 | 10 | 15 |
| 80 | 12 | 18 |
| 90 | 14 | 21 |
| 100 | 16 | 24 |
| 110 | 18 | 27 |
| 120 | 20 | 30 |
How to find out battery capacity in Watt-hours (Wh)
Step 2
Now divide the board’s battery capacity number (Wh) by the efficiency number (Wh/km) to get a rough range estimate for your weight.
Suppose you weigh 70 kg. According to the chart, an electric longboard’s efficiency for you would be about 10 Wh/km.
And suppose you’re looking at a board that has 216 Wh.
216 / 10 = 21.6
That board should be able to carry you about 21.6 km.
Now suppose you weigh 90 kg. The board’s efficiency is now 14 Wh/km according to the chart.
216 / 14 = 15.4
That same board now carries you about 15.4 km instead.
Rough estimate only!
The chart assumes the following conditions: smooth road, no inclines, mild acceleration, mild weather, about 30 km/h, and standing pose. A change in any of those conditions can greatly affect the range.
Don’t expect the estimate to be very accurate! It is meant to be a convenient way to help you estimate range based on your weight before you buy a board. Many variables influence the actual range of a board.
