Just for info although it could have just been a bad experience for me. I bought a pair of Morpilot 7.4V 2700mAh 10C 20Wh batteries and balance charger from Amazon (link below) designed for my Hubsan H510S but during the first charge the balance charger started to spark and smoke which was a bit worrying. Amazon were excellent in dealing with my return and refund however. As I say it may have just been a one off bad device.
