DJI O3 UNIT GROUND COOLING STATION

I made a ground station for cooling the O3 unit. When you set up the drone in betafly or when you expect to capture satellites in the field, this unit gets very hot. I had two computer coolers measuring 40x40x20 (12V 0.16A) lying around and I decided to try to make such a cooling station from them that you can also take with you to the field. Maybe someone will need it - I will be grateful for your feedback.
The size of the station is calculated for the VAPOR D GEPRC

There is a charge indicator in the photo, but another switch needs to be installed for it. That's why I removed it in the final version.

1.The board for powering the coolers and simultaneously controlling the discharge/charge can be purchased here: https://www.aliexpress.com/item/1005006273147369.html?spm=a2g0o.order_list.order_list_main.636.12a1180227mFc3
BE SURE TO FIRST ADJUST THE VOLTAGE AT THE OUTPUT OF THE BOARD WITH A MULTIMETER AND ONLY THEN CONNECT THE COOLERS.

4. I use battery 21700 

After printing, I glued the cooler case with super glue to the case where all the electronics are located.
