I'm sorry I don't have the link now but I watched a video where the presenter suggested we should let our batteries on the Phantom 3 cool right down after use before recharging them again, giving very good validation as to why. Just a thought? Now this might be a long shot and I'm in grave danger of making a complete prat of myself but here goes. I bought an electric motor for my bike [bicyle] and after a while noticed after not too long into a journey the battery would simply cut out as if for no reason. By knocking the on/off switch I was able to restore power once again but soon discovered on a journey I may have to reset a few times even though there was lots of power in the battery. The system is 36v and uses a Lithium battery. After watching the video I wondered was I having trouble with my battery because instantly when getting home, I was putting it onto charge. The last couple of trips out with the bike I have let the battery cool down for an hour and can now report the battery hasn't failed into a journey yet! As some Phantom pilots report their birds falling from the sky for no apparent reasons is it possible this is a Lithium battery problem while these batteries have been charged too soon after use? Ideas anyone?
