I want to fit a small fan to vent my battery box when the battery is
charging. I only want the fan to run during charging, so was thinking
of a relay that would only close when the voltage is above 28v or so.
Any ideas???



Don't put ANYTHING in the engine or battery compartment that has anything
to do with CONTACTS opening or closing! BOOOM! Hydrogen gas!

You've never seen a sealed relay?
