First of congratulation on this nice build. Thanks for sharing the Eagletree graph. Seems as if the car needs around 45A @ 36V to maintain top speed (1600W). Hard to tell without zooming in further into the graph.

Could you attach the eagletree data file "baja221510slast.FDR" i would like to get a better idea what exactly happens from an electric point of view when moving a 1:5 vehicle.

Around 540W average is less than i would have expected, but this is mostly related to the driving style. 110A (3800W) peak is not that high but seems to be due to the grip limit of the rear tires (Batteries may also be the limit). I guess you were still running your "older" lipos (older generation PQ5000 with 25C) as voltage drops to min 32,91V.

Did you already drove it offroad? Might not be that easy to find a good offroad bashing spot in a big city like rome ;-)
