the dino comparison is:
4S 2200mah 70C weighs 258g and costs $50.00
What do I gain in performance going with graphene v lithium for the price difference?
Hey Hawk, Just looked at those, I wonder if they have a Graphene anode? I am skeptical about the 70C claim, even for the Dinogy batteries that I mentioned.
My guess is that they are all good for 45C and maybe can do 70C for less than five seconds. I have to admit the price is pretty good so I will try a couple and see how they do. Thanks for the heads up.
Oh yeah, the main performance edge for graphene batteries is that they can maintain a low internal resistance for more charge/discharge cycles than standard lithium ion batteries. They also give you a little extra flight time since the discharge curve is less steep near the end.
