In my work I create mathematical models(using machine learning) for explaining complex vehicle dynamics given the control commands and velocity of the vehicle. I plan to employ some of those methods to generate an accurate model to predict the range of your vehicle. To do so, the more the data points the better. Please don’t be afraid to post whatever information have. To start off please enter data in the format below, later I can create a webpage to get the data from you. The same webpage will include a calculator for people who want to get their prediction too.
Please let me know if you think of any other important variable or if you notice any mistake
if you don’t have a field, or don’t feel like answering then just say “none”. Also you don’t have to include “#” or anything after that. It would be treated as a comment. format: ++++ weight: 90 # rider+board in kg cell_min: 3.2 # min cell voltage cell_max: 4.1 # max cell voltage cell_capacity: 2.5 # advertised cell capacity in Ah(not mAh) cell_name: 25R # 30Q, HG2… Whatever name you know.

In addition if you have the metr pro log files that would be awesome.
As per the best of my knowledge, existing calculators don’t take several important factors into account. Interface of such a calculator found in one of the threads show that.
