I run some computer case fans from a 12volt car battery in my Garage to keep the air flow moving and prevent condensation in winter. I borrowed the idea from classic car air chambers, thinking why not make the entire garage an air chamber, keep my tools and everything else dry at the same time.
I would like to upgrade the system and make it more controllable. In the past I have bought fans and they barely last any time at all. They are just connected straight to a battery, which runs until it goes flat, then I swap it far another charged one and charge the flat one and so it goes on.
I think (could be wrong, appreciate your advice) it's probably hard on the fans, running full speed for a couple of days, then struggling to run increasingly until they stop, only to be out on another fully charged battery and the process all starts again. So I had 2 thoughts, one I have some kind of switch which wold allow me to reduce the voltage, so they never run at full capacity or, two I have a system where they switch on and off using some kind of timer. Both wold be better with additional protection for the hardware, a fuse would be nice, maybe a relay but I know very little about them. Working on cars they get replaced when they stop working with another the same, so I have never actually designed a new system with replays or anything like that.
Appreciate any advice anyone can give, thanks in advance
Apologies, Dangerous newby loose on the site. I have just noticed I am in the wrong place, can anyone on her move this to a more relavant section, Sorry
