What if the down force fans only turn on during the slope/turns? That would improve time on straights, right? Also, while we're on the topic of SETSUNA, what if super capacitors kick in on the drive motors during straights too? LIke dash on straights and ease up on turns and slopes.
Very cool! For slight performance gains, you can charge the li-ion slightly higher than the recommended 4.2V to around like 4.3V. There is not much energy gain from 4.2V to higher but you might get higher power output. Another performance gain would be to increase the battery temperature to around 40C, doing so will decrease internal resistance so you get less voltage sag under load. Of course be careful, as both of these optimizations will increase the risk of fire and will definitely decrease battery life. I love your engineering approach to your cool designs!
