# Summary

A simple cooler to force air through a Phantom 4 Pro battery. In my testing, this cooler will take a hot post-flight battery to cool enough to charge in about 1 minute if the ambient temperature is around 75-80 degrees Fahrenheit.

It is powered using a 12V car outlet, or via any other 12V power source. It can also be run off 5V but fan speed (and cooling speed as a result) will be significantly slower.



##Hardware Needed:

2 - 40mm x 28mm Fan
