TOPIC: Graphene battery Packs

Graphene battery Packs 1 year 8 months ago #47

Hi Guys back again and as always im asking questions :-) I was looking through Simons Project picture ( Nimbus E Paramotor Project here on this forum) and Noticed he was using Graphene Battery Packs 8 & 10AmpH so wondered what the state of play was with this new battery tech ..

Can any one provide some pros and cons of this battery tech , the one thing I did see was the discharge rate is not as high as say the LIPO packs I have ,

is this an issue ? the price seems fair given its new tech but performance wise what are the other Pro's and Cons, My thoughts and design brief will be based around my E paramotor drive, will be for getting up high enough to latch onto thermals but not for long duration flights , so for me its flatland take off get up to say 800+Meters and if not lucky with thermal will be content to glide down .. recharge and try again ..

Hi.. I've used the 16 ah 6s graphene packs and they are very good. Just wish they were a 14S for my setup. I put two of them in parallel in a Ryobi drill case. I actually have them for sale

hi again.. just wondering about your desires. Flatland takeoffs at 500 m to get to 800 m are doable. but from zero m to 800 m is a stretch with my experience. You would need a very good motor and a very good battery to get there. Tnis is because you don't really want to fly full throttle very long as it both heats up motor, battery and controller and decreases greatly the flying time. At the moment, this is one of the limitations of electrics - it's easy and gradual vs full power.

Hi Ozflightclub thanks for the feedback , and nice to know there are graphane users out there, my initial brief was a wee bit ambitious as im still trying to get the grips the requirements of E=flight .. im lucky that my local flying site has a small hill from which most of my flights will be made , thinking along the lines of standard paraglider launch then once airbourne the E-one system will be used to latch onto the 1st thermal or at least allow for extending glide circuit if that makes sense ..Cheers for feedback its all very much appreciated

hi Wannabeaflyer, just seen your post. hobbyking graphene battery packs are good, when you have less than 5c,
otherwise your voltage will drop faster and you loose power. currently I use these lipos, a little bit better
www.stefansliposhop.de/Akkus/SLS-Multiro...V-30C-60C::1638.html
also I preheat my batterys > 25 celsius. when you climb, it will be colder rapidly, so when you are below
18 celsius, battery will loose performance. with 10 celsius you will loose 50% of possible C rate.
so higher C rates (30+) are also better, even if you have low C rates in flight.

there is good german site, they make professional tests and are indipendant
www.elektromodellflug.de/turnigy-graphene.php (some packs have quality problems)
www.elektromodellflug.de/sls-quantum.php (good results)
www.elektromodellflug.de/lipo-leitfaden-faq.html (general things about lipos)
maybee you can use google translate.

Hi Simon
Just to say big thanks for the info , i'll kick google translator into life to see if I can read the info on the German RC forum . im sure those guys have put some good info there.
I still have yet to start my assembly but most of the elements to build my- E-one are coming together and a few delivery's more and Some items to make and I should start adding some decent updates on my project post's...

all Info here is good and we all seem to be stepping up the pace , so this is great stuff Cheers

Pross would be overall enhanced battery (better conductivity, faster recharge time, less weight), cons would be still notably higher price. If you spend a lot of time on your phone, then just go for it. Its worth it. :) You can read some more info about graphene here . It really works like a charm.
