to the right rear there is a ventilation section next to the seat. is that the intake for the OEM battery/cooling? if you want to have extra cooling, can you attach some fan or air by it to give extra cooling? vegas = 110 degree heat! i see my MPG going down to around 45 mpg.. winter was closer to 50 mpg
Do you need an extra fan or do you need to run the fan faster? Scangauge II mounting location and battery fan modification PCB | PriusChat
