prusaprinters

<p>A simple cooler to force air through a <a href="https://click.dji.com/AK5sM0J7okY4V-1zEIYg6Q?pm=link">Phantom 4 Pro</a> 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.</p><p>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.</p><h3>Hardware Needed:</h3><p>2 - 40mm x 28mm Fan</p><p><a href="https://amzn.to/3sMq4m6">https://amzn.to/3sMq4m6</a></p><p>(The above Sunon Maglev server fans are expensive but they do the job as you would hardly believe incredible little fans.)</p><p>&nbsp;</p><p>2 - 40mm Fan Grills (optional)</p><p><a href="https://amzn.to/3zv0TYW">https://amzn.to/3zv0TYW</a></p><p>&nbsp;</p><p>1 - Mini Toggle Switch</p><p><a href="https://amzn.to/3WfPnuh">https://amzn.to/3WfPnuh</a></p><p>&nbsp;</p><p>1 - DC Power Jack</p><p><a href="https://amzn.to/3NmtW6I">https://amzn.to/3NmtW6I</a></p><p>&nbsp;</p><p>4 - M3 x 40mm Machine Screws</p><h3>Post-Printing</h3><p><strong>Wiring</strong></p><p>Simply solder the positive wires from the fans to the switch, and wire the other side of the switch to the positive terminal on your DC power jack.</p><p>Then solder the negative wires from your fans directly to the negative terminal on your DC power jack and you are done.</p><p>Lots of room has been left for wires and cable management.</p><p>Category: R/C Vehicles</p>
