So I recently received my phantom and have done a couple flights, but am already running into battery issues. The stock battery that came with the phantom doesn't seem to want to charge. I plug it into the charger per the directions from the dji website, but even after multiple hours it still is just blinking red. I believe I've read on here somewhere that it should be more like 30 minutes so it makes me think something is wrong. Is there something I did on the first couple charges or flights that could cause this or just a faulty battery? My reading makes it seem like there are a lot of caveats with these lipo batteries in order to make them last and not catch on fire and I'm worried that I'm not following them all. Also, since I was planning on buying spare batteries anyway, can anyone recommend what to look for when buying batteries? Who are the best manufacturers? What sizes fit inside the phantom? Thanks for any help.
