Worthless!
I purchased two 3.7 400 batteries to increase my flying time for a recent purchase. Both batteries were plugged in to charge before using them. Both batteries registered that they had charged to the appropriate point. I placed them in the drone. They never worked! Both batteries swelled to three times their original size. I feared for my safety after trying to use these batteries in my drone!I have requested to return them. But they say that batteries can not be returned. So, what do I do?

Good Battery
It won't work for Sky Viper drone. I modified the plug to make it fit. It's not that difficult since it's plastic. It works well so far. Considering the price, I would say it worth the money.
