My dad is giving me his phantom 1, and he has the original 2200mah battery as well as about 5 - 2800mah batteries. I will eventually do the 1.5 upgrade, and someday step up to a bigger platform and would like a charger that will last me. I do have the stock DJI charger, but I'm sure there are better options out there. Kinda wish I kept my stuff from my RC heli days now lol. Suggestions?
