This is the second charger I have purchased from this company. The first was for my Phantom4. I've charged my batteries too many times to count. Never had a problem. I never charge my remote control at the same time as the batteries. Not recommended. People who do this put too much pressure on the charger and burn it. I'm a bit disappointed that this one didn't come with LEDs like my other one. The main thing is that it charges quickly and evenly. Love it.
