It was the air vents that sounded most vulnerable.
put them high up, thats all.
Then they'll be a long way from the battery and less efficient. And
most likely ugly looking as well, with room from the car's footprint
required to accommodate the ducts.
You men in the same way a cars air intake is a long way from its
exhuast pipe?

No, in the same way that many cars have an air intake rather low down
that doesn't cope with floodwater. Except that air is for combustion
purposes, and is drawn in with quite a "suck", but extended pipework for
ventilation ducts for your batteries will reduce the cooling efficiency
significantly.

Not really.

You can use a pretty large cross sectional area.

The packs don't need THAT much cooling anyway.

Worst case would be toiling up a long hill.
