Phantom 4 Battery Cooler adapter

This is an adapter to fit over the Phantom 4 battery and hook up to a 12v Hotor Car Vacuum. If you are field charging your batteries then a critical step is cooling them down after you take them out of the P4P. Using this adapter and the Hotor 12v hand held car vac will cool them down in less than 2 minutes. I was using the hose and just holding it up to the battery and decided it was time to upgrade.
