Since I can't get extra batteries, like a lot of others, I have to use my one over and over. Using the inverter in my car, I first crank my A/C up high, then hold the battery in front of one of the vents. Resting left arm on steering wheel helps some. I then rotate all four sides, horizontally, about 2-3 minutes each side. It usually cools it down enough to start charging, about 8-10 minutes. Just a tip if interested.After you fly, let the battery sit for 20-30 minutes before you charge.
Got my backup P3P today! Using the remote control (my gimble wheel has a loose connection and stutters moving downward) and the battery. Out flying, and using the inverter to charge both of them in car!!

ok guys your not gonna like this but it is very bad to use cheap inverters .these batteries are very sensitive to different amps and fluctuating voltages.be very careful using them on smart batteries.unless you don't mind waiting for a 150 dollar bat forever to come.lol
