Battery and Power Module Setup | PX4 User Guide (v1.12)
If you had a 3 cell battery pack your pack would be 18.5Wh X 3 = 55 Wh of stored energy. When you take battery weight into account you calculate energy density by taking the watt-hours and dividing them by weight. E.g. 55 Wh divided by (battery weight in grams divided by 1000). Assuming this battery weighed 300 grams then …
