Battery Power Vent Fan – 12V
Ready made 12 volt brushless fan with back draft damper for easy (vertical) installation in your 2″ PVC battery vent pipe. 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 uses to vent his battery boxes and prevent cold air backdraft in the winter.
