William,
I'm planning to use a 48 V battery vent fan, turned around backwards, to
blow air into the box.
Thank you,
Drake

I tried running 48 VDC muffin fans on battery voltage. They failed. I switched to a Dc-Dc converter (12 or 24, can't remember) from digi-key and problem solved.
Point being battery voltage ranges may be too extreme for some components.

Hello,
Does anyone know of a 48 VDC temperature sensing relay? I need to use one to control a fan in a 48 V battery bank, to bring in cold air when the bank gets too hot from the wood heating system in the house.
The relay needs to operate with the 48 VDC power supply and disconnect a small current with 48 VDC contacts.
Thank you,
Drake
