Help wth a 12v DC circuit Answered
2 Questions please
I am working on a hobby project and I am needing to hook a 12v computer fan (200mm) which is 0.3A max...up to a Turnigy 5.0 Li-Po battery. The battery is 7.4v, 30-40c discharge, 5000mAh. I have ordered a DC to DC adjustable voltage "step-up" converter to increase the output to 12v (I am hoping this works). (Q1) - how (if at all) do I limit the output amperage to 0.3A without burning up the fan motor.
The fan is going into a cosplay set of foam armor (to help keep some air flow going to try to keep semi-cool) and I am hoping to be able to run the fan for about 3hrs. If I can accomplish the above, (Q2) - how long might the fan run?
Attached is the "step-up" I ordered...
