Calibrating your Current Sensor in INAV

In this video we look at how to calibrate the current sensor in INAV. There are a couple of ways to do this. A popular method is to use a charger and compare the mAh put back in to the pack with the OSD reading of the mAh used. However, this method is not very accurate, for a couple of reasons. Using a charger, you not only have to consider the accuracy of the current sensor in the charger. But, also the cut off point is an unknown. If you take the mAh reading as the balance charging commences, the chances are the reading will be too low. If you take it when balance charging completes, it will be too high; as balance charging charges the pack, then drains the cells with the most charge. This method also only alters the current scale. It does not take the offset in to consideration, meaning unless the offset is zero (highly unlikely), the scale will be wrong. The method shown in this tutorial is more accurate, as the only device that we need to worry about the accuracy of, is a device that has been specifically built to read power and current. The big drawback of this method, is that we need to power up the motor indoors.
