[RE-wrenches] battery box fan

[Darryl Thayer]

If your fan is less than 1 amp, like a small computer fan, you can power the fan directly, else you have a problem, because you have 48 volts and need a 48 volt fan or a voltage coverter 48 to 12 volts. Solar converters makes such an item aloong with others.
