LeGow 3.7V 800mAh Lipo Battery with JST Plug 1 to 5 Charging Cable for JJRC V686G V686J V686K RC Quadcopter

Prompt delivery and good quality for my drone. This allows the kids to have lots of funs in lake district without worrying flying close to the airports.

They charged up fine, lasted longer than the originals

Only spare batteries that actually works with the JXD 509 Quadcopter. I tried several other batteries and they all failed miserably. These do the job perfectly, in fact, far better than the original battery!

Use these in my JXD 509G. Better than the original supplied battery. Fit easily in quad and provide much needed extra flying practice.

work well

I have seen people say you can get 7 to 10 minutes flying time from these. I have a 509v and it fly's 3-5 minutes at the most on a full charge. So there not really that impressive. But they are cheaper than some on the market

Sorry to say they are not good don't hold charge only run for 2 min's a waste of money don't buy !!!
