3 x 7.4V 2700mAh 10C Battery & Charger Set for Hubsan H501S H501C X4 RC Quadcopter
A part of the review has been auto-translated.
They look original Hubsan but I don't think they are. On the first two flights they gave me the same flight time as the original battery, almost 20 minutes. So I'm happy with them. However don't use the cable in the package to charge the 3 batteries at once. Using thi cable will cancell the balance charge since each cell of the battery can't be read by the charger. Just charge them one by one. It will take you a bit longer, but it will keep your batteries in better shape in the long run.
Boa autonomia de vôo. A única coisa que tenho a reclamar é quanto ao plugue da fonte de alimentação que me mandaram no padrão americano e o adaptador que mandaram também é no padrão americano sendo que pedi no padrão europeu. Conforme foto do anúncio.
