Does anybody have a link to a runtime calculator? I am working on a highspeed 8ight 2.0 project and I am trying to select the batteries for it. I am thinking since this will be used for max top end speed I could go with smaller bateries for lighter weight but I know runtime will suffer as a result. I just want to know by how much. Running 2 3s 5000 mah batteries would be nice but they are very heavy (about 30 ounces) so I was thinking of getting a couple 2500- 3000 mah batteries(18-20 ounces) and saving a considerable aount of weight. but If I would only get 5 mins of runtime i won't do it. Is there such a calculator for cars?
Thanks
