This batteries fit a little tight on Syma X5 Quadcopter. About 3 grams more than genuine battery and lot of more time and punch to fly. I recommend this batteries a lot.

These batteries are a perfect fit for my WLToys V931 helicopter. Just one thing : I use a small piece of tape to stick down the flap which otherwise tends to get in the way a little. The larger capacity also gives longer flight times of course. Good quality and a very nice price from Banggood.
