Power a 12VDC cooling fan using LEAST amount of space possible using a switch. This needs to fit in a small helmet.
I connected the fan (+) to the switch (+) and those to the battery (+), then the fan (-) to the switch (-) and those to the battery (-)
It worked just how I wanted but after about 60 seconds the battery got VERY VERY hot. I did my research and found that this outcome is normal but couldnt find out how to fix it.
PS: I am new to this website ans suck at electrical stuff.
