Frequently Asked Questions
How do I choose the right EV motor?
Motor power depends on speed, weight, terrain, and use case. Our tool calculates the exact wattage needed based on your specific parameters to ensure you don't underpower or overpower your build.
How big should my EV battery be?
Battery size is calculated based on Wh/km consumption. We estimate your efficiency based on vehicle type and speed to recommend the optimal Amp-Hour (Ah) and Voltage configuration.
What wire gauge do I need?
Safety is paramount. The calculator automatically suggests the minimum wire gauge (AWG) based on the peak current draw of your controller to prevent overheating.
