In our product specifications, you may notice that we list two numbers for certain specs where other brands typically show only one. This article explains why using the Aero Pro’s specifications as examples.

Battery Capacity

222Wh (227Wh)

The Aero Pro uses Molicel P45B cells which Molicel rates at 4500 mAh for “typical capacity” and 4300 mAh for “minimum capacity.” Actual capacity varies based on testing and usage conditions.

Most electric skateboard brands use the highest capacity rating for their calculations but this does not reflect real-world usage. We provide both a more realistic capacity (222Wh) and the industry-standard calculation (227Wh).

50.4V * 4.4Ah = 221.76Wh

50.4V * 4.5Ah = 226.8Wh

Voltage

50.4V nominal
58.8V max

In most industries that display battery voltage, such as e-bikes and e-scooters, nominal voltage is the standard for marketing. However, electric skateboard brands often advertise maximum voltage instead as there are fewer industry regulations, and higher numbers may appear more impressive to customers.

We list both the nominal voltage (50.4V) and the max voltage (58.8V) so customers can make informed comparisons across different products and industries.

Motors

Hobbywing 5250 (4230)

In industries that use brushless motors—such as electric skateboards and drones—it’s standard practice to express motor size using the diameter and length of the housing as a single number. For example, 5250 means a motor with a 52 mm diameter and 50 mm length.

However, Hobbywing names its motors based on the size of the internal stator instead. The Hobbywing 4230 motor has a stator that’s 42 mm in diameter and 30 mm length.

Since many electric skateboard brands use Hobbywing motors, motor sizes have been expressed using both conventions. This has caused confusion when comparing sizes.

For clarity, when listing Hobbywing motors, we list both the industry-standard housing size (5250) and Hobbywing’s stator-based size (4230).

Speed Controller

40A continuous
50A peak

Aero Pro’s ESC is rated for 40A continuous and 50A peak. These numbers represent the amount of current the ESC can handle under different conditions.

40A continuous is the maximum current the ESC can handle over extended use without overheating. This is the more important value for most riding situations.

50A peak is the maximum current the ESC can briefly handle during high-demand moments like rapid acceleration or hill climbs.

Marketing only the peak current gives the impression of better overall performance than the ESC can actually provide in regular use. We list both values to give a more complete picture.

Power

2352W sustained
2940W peak

The Aero Pro is rated for 2352W sustained and 2940W peak power.

As with ESC current ratings, some brands emphasize only peak power to make their boards appear more powerful in marketing. Even worse, some use the motors’ rated peak power to misrepresent the board’s overall power.

We provide both the sustained and peak power ratings as calculated from the battery’s max voltage times the current the ESC can deliver to give you a more complete understanding of how the board performs.

58.8V * 40A = 2352W

58.8V * 50A = 2940W
