Battery Power Vent Fan – 48V
Ready made 48 volt brushless fan with back draft damper for easy (vertical) installation in your PVC battery vent pipe (2″ inlet and 3″ outlet). Use a charge controller with an auxillery connection available (Outback, Midnite, XW) and our O-MINIRELAY to turn the fan on when the battery is at or above gassing voltage.
This is what Shawn at Backwoods use to vent his battery box and prevent cold air backdraft in the winter.
