are these more powerful then lipo

They ARE LiPo.

There is no such thing as a MSDS sheet. They have been replaced by MDS sheets. I guess having more than one "S" was to confusing

Just got noisy but was able to land no problem. :30 longer flight time than my 3700 but that's probably due to the Mah difference.

95amps that 480 had to be a rocket ship

Yeah I was surprised that the amps went up both my pulse and these are 45C. Guess that's why the swash separated haha. I glued it back with some green Loctite

I would consider ordering the Lynx swash, if I were you. I've seen enough come apart that I'm done using Mikado swashplates on my helis.

Didn't even know there was a lynx one. Thanks I'll take a look
Hmm all I see really is a 690 Lynx swash. Nothing specifically for the 480

what is so special about these

Cycle life. One of the beta testers has over 1000 cycles on one, and the battery is still usable. Also, they don't seem to get as hot after a punishing flight, which probably also helps the cycle life.

oh. Thats great

So I gotta chime in .Everybody here talks about the Graphine batteries ,costs, voltage etc. I'm also quite certain we all spent a lot of money building our helicopters trying to get the best performance (power to rate ratio ) that we could afford. For me it was a 600 and 700 size heli
This what it comes down to,I run the pulse 3700's @45c in my 630 at a weight for both batteries of 1182 gr. The Graphine 4000 @ 45c for both batteries weigh 1396gr.Thats 214 gr or 7.54 oz. more than the pulse that's close to a half pound more. No thanks.
In my 700 I run the pulse 5000 @ 45c for a weight of both batteries of
1530gr. Again the Graphine 5000 @45c for both batteries weigh 1716gr.Thats 186 gr or 6.56 oz. Wow, again no thanks!
When I went electric I wanted the greatest performance possible otherwise I would have stayed with nitro. So this is my take on all of this, yes batteries are expensive but like I said I wanted performance, and to get it I will spend a little more on my batteries. So good luck with your Graphine boat anchors.

yep weight plays a big part in helis

[oliver1071]

Did really notice the extra weight on my 480 but it's already a nice and light heli.

[macdad]

I am not a 3d guy, so I am likely missing something here... If my 12.5 lb 700 size helicopter gains about 0.5 lbs, it is a show stopper? That is a 4% increase in weight. I will have to try some out to see for myself.

Personally, if I lost 30 seconds flight time but gained 300+ cycles on a set of batteries, I would still buy them. I fly 4000s in my 700 and easily get 5:30 minutes of flight.

Edit: I actually compared the weights of 4000 6S between Glacier and graphene. The difference is a 28g per battery. That is a whopping 56g increase!

[Raptorapture]

It's amazing how people have to justify their choices as if others have made a poor choice. Decided to go with product: best thing since sliced bread. Decided to skip product: even my Grandma wouldn't touch that with ten foot pole.

This graphene development happens to be a serious advancement that we will only realize the benefits for the majority as it evolves. It's kinda cool it comes from the HK folks given all the bad rap they get.

This round will be good for those that run their packs through to the end of their lives and wish to spend less. This starts to reduce the cost dent that electric heli's have had on the hobby. I for one have never retired a pack except yesterday when I discovered what Team Taco membership means and therefore probably won't benefit. Although it does seem like it might be a good option for speed training given the resilience.

Most people don't even know what 56g actually feels like....so here's something to think about. A standard size brushless servo weighs about 70g...and a micro heli like one of the E-flites weigh about 40g...

I think most people want an uber light model. The thing is that weight really is not that big of an issue. The issue is how well you can fly it. I think Kyle Dahl has proven many times over that a heavier model (even the Logo 800) can be used to win in the biggest competitions on the planet.

When did kyle win a competition with a logo 800?

[Boinker]

You know these look cool but the sheer weight of the, which has been commented on before, is just too much. Sure cycle life being wicked high plays a roll and bang for buck is awesome but if they are as heavy as they say it will be so detrimental to performance it just won't be worth it. At least in the 450 class for me.

[gimbleguy]

At this current time all my helis are on the Jenny Craig program.

I understand it's still early stages for this lipo, if they can pull off a lighter weight version of it, then I'd consider paying the extra $$$. For now, I'd rather wait until that happens or something better might come along. Perhaps Ceramic Lipos? Or what ever.
