2 x WLtoys V931 RC Heli Parts 3.7V 720mAh 25C Upgraded Battery
A part of the review has been auto-translated.
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.
batteries supplémentaires pour hélicoptère xkk124, rentre tout juste.
very pleased with them always receive orders from bangood thank you
Those batteries are too long. I had to round the corners, but even with this, it is very difficult to close the fuselage. It often opens during flight. I tested SKU139221 which is described as having the right length, i.e. 40mm. But in fact they are 43mm long and don't fit either. The only solution seems to be SKU154339 which is relatively expensive.
Everything great right away again
