Wow!!! It's like I bought a new watch or something.  This packaging is way over the top.

Nice! i bet half of the cost they spent on the package

Yeah.. I think so.. Still cheaper than tatoo. I want to do a comparison. Is there a good system to compare the 2?

good question actually i have also been looking for a way to test batteries, let me ask that in the MI group

I got a couple but I'm not totally convinced that they are the greatest batteries in the universe.
Sure the rubberized cover material seems really nice but performance wise I didn't get that much out of them.

Real world usage I got a much better experience from DroneLabs 1500mha 4s 50-100c
I used Turnigy 1000mha 4s 65c
Also, to make matters worse, one of them got the + disconnected only after a couple of flights!

So would you rate these Graphine batteries better than Turnigy nano-tech ones ?

I haven't even used mine. I feel bad taking it out of the velvet sleeve

That really looks fancy.
A good way to test them would be to set yourself a basic course and fly around as equally as possible with both batteries. Write down the voltage, plug in and charge. Then write down the mA put in by the charger.
En this 3 times (or 10) for each. You can then notice how each battery behaves.
Then, of course, the feel of each one in flight is up to the pilot to decide on.
