Hobbyking Graphene Lipo Review and Teardown

This video is not meant to prove that there really is graphene or no graphene. Its simply meant to answer all the questions ive been seeing about why it weighs so much! we just wanted to see what was inside, is there anything drastically different, compared to other lipos? Is there graphene? maybe if its sprayed on somewhere, but overall appearance is similar to other lipos ive taken apart. Definitely some added weight from g10 plates and heavy heatshrink. we just wanted to take it apart to see what was inside.:)

the commercially made graphene i have seen (YouTube clips only) have been a fine powder or tiny flakes. they could have mixed graphene powder in the dye for making the cathodes to increase the conductivity. or it might just be marketing bullshit. who knows...

thanks to your friend to sacrifice in the name of curiosity. I am very skeptical of the graphene claims, cause it is a capacitor, not a battery.

Google and 5 minutes will find you some mention of graphene in the anode or cathode part of the battery, about 4 years ago. I still think these are slightly enhanced batteries, with a leap forward in internal resistance and increased charge cycles with less capacity loss.

not sure why you are getting so many dislikes, you took apart a battery and found battery guts. Maybe next time you should photochop in a flux capacitor to make the masses happy!

Great video thanks. I knew there was no real Graphene in these batteries. More Hobbyking bs!

Viewer discretion advised - Batteries were harmed in the making of the episode

If the graphine claim isn't totally BS, I'd imagine they mixed it into the cathode material.  And that actually decreased the conductivity or some of the electrical properties, so they had to add more layers to make them fatter.  which maybe has the result of being more forgiving of extreme conditions and temperatures.

It's just a standard lipo cell that uses graphene to improve its characteristics. it's still a regular lipo but they just added and extra ingredient.

That looks like a capacitor internals therefore much quicker to charge

[HoverbotTV]

Graphene is the colour of the new packaging man not some element in the chemistry. Thicker plates my guess. LOL!

Ooooph... Just dropped 300 on 11 of I need some tissues....

[ChawFPV]

could u do some sort of test of all those lipos. I see u have all of them. let's see which is best!

[AustinPetDetective]

Thanks Hobby King for selling a standard Lipo battery for a more expensive price Lol.

[AussieRC]

Great video.. They just put that stuff around it, so when lipo goes puffy you won't feel it as much lol

[rainlesure]

it looks to me as though they made a supercapacitor with that and all right she has a separator the liquid you're talking about as a electrolyte and the black stuff is the collector plates

[blameusa]

cheapest battery maker + bleeding edge tech = BS

it's very helpful to know that you guys and gals are taking this up to the manufacturers... keep at it....it is so very helpful for all of us consumers...:)

I'm getting about 1250 maH on these. My Vortex pro has a pretty good OSD and that's what it's saying at the end of a flight on average with no margin. i usually land at about 1000 mah just to be nice to all my batts.I haven't noticed anything different with the performance. None of 4 I bought puffed yet with 20 flights but that's normal.

[barharborbasher]

thank you so much for that break down !!! I'm a custom rc builder and I just recently purchased a Pro Built Storm "Buster"4s drone racer and I'm excited to fly FPV!!subscribed!!

[elandruz]

The graphene is on the electrolyte¡¡¡¡¡¡¡¡¡

Thankfully I learned not to trust Hobbyking many years ago, and it still stands today. Thanks for sacrificing for the truth.

When I initially saw the bigger size and weight I hypothesized that that meant these batteries have a higher capacity than is mentioned on the label. Using graphene would mean that they could have increased the total surface area, and decreased the internal resistance, both resulting in less mass and size or more output for the same mass and size of regular LiPos.
However, a 40c battery with slightly more capacity can put out 40 times that capacity in amps, which (I thought) is why they appear to be more powerful than the other batteries: they actually are bigger batteries than the ones we are led to believe are direct competition.
This hypothesis could be tested by measuring the capacity, but I opted out of buying these and went for lighter ones instead. Could you measure the capacity of the remaining cells?
