Hi All, here is a video that goes in to detail about using the spreadsheet. It discusses the use of internal resistance on the battery you plan to use and the load factor of a brushless motor.
This is a great video for pointers on how to use the sheet.

In addition, the video discusses the differences in performance of different LiPo battery packs. The pack with the lowest IR performs the best. High demand systems will put significant strain on poor performing LiPo’s as shown in the video.
