Bought an additional OEM charger from Drone Pros through Amazon. Used the charger once and it worked fine. The next day went to charge another battery and all the charger did was repeatedly blink red, one bright blink for a second followed by a very dim blink for a another second. And, then began to get too hot to touch. I connected the battery to the original charger and no problem. We've had the newer charger for 34 days and we'll see if Amazon does their usual good stuff. Anyone else experience this charger problem?
