With the cold weather we've been having and DJI's suggestion that batteries be heated up to 25*C or warmer before flying I found it weird that I couldn't find a battery heater for a reasonable price. DJI does makes a nice heating unit for the Inspire batteries but no love for my Phantom 3, this lead me down the DIY path. I started to look for a 12v solution as I intended to use this heater while I was out and about in my Jeep. I was initially thinking I might use an automotive battery blanket but all that I found were non-adjustable and ran 65*C and warmer, way too hot for my little P3 batteries. I then realized that my Jeep and most newer vehicle manufacturers are nice enough to add a 115v power supply and this was perfect to run a small therapeutic heating pad which I found on sale for about $15. Now all I needed was a small box to put it in. It didn't take me long to a nice Plano box on sale for $5 and I was set.
Cut a quick notch in it for the cable to run through,
Stuff the heating pad into it and I had a pretty good $20 battery warmer that fit four P3 Batteries just perfectly!
Drill a few holes in the top, add a few zip ties to clean it up a little...
