PaulFillion Voltage sag, internal resistance and "C" rating are related. Voltage sag is equal to the internal resistance times the current draw. The power dissipated in the battery as heat is equal to the voltage sag times the current, or the square of the current times the internal resistance. If the power dissipated in the battery is excessive, it swells and is ruined. That limits the maximum load, which is expressed as the 'C" rating. There is NO WAY that a battery with high voltage sag is 70 C!

A bit disappointed with these batteries. I have been using the Tattu 850mah 75c 4s batteries on my 3 inch quad and decided to buy these since they were so cheap and 70c which I thought would perform similarly to the Tattus. Unfortunately I was wrong. These batteries aren't nearly as punchy and they sag pretty much instantly and give a low voltage warning as soon as you give it some throttle. They are

PaulFillion Wish I had read the reviews before ordering them. Haven't tried them yet, but hope to soon. However, the reviews read about the same as the "ZOP" batteries I have used, and they are absolute garbage. Customer service doesn't seem to understand that you can't fly an expensive model around if you don't know when it will suddenly lose power and fall out of the sky.

these was the worst battery I ever purchased. They are huge and have no power they sag almost immediately when flying. Don't do it!
