The graphene supercapacitors will stop all lipo voltage drop from high current draws when you hit the throttle, but they need to be used with the lipo packs, and not try to replace them... No way a lipo pack is going to compete against a combo of graphene supercapacitor and another lipo pack of the same brand and size.... Remember, the supercapacitor is only there to stop voltage sag for a second or so, not to run the car for six minutes, and the new graphene supercapacitors have way less resistance than lipos..All that's need is a difference of 0.5 volts for a second after each corner to make a huge difference.... It won't be long before we start using them, if some are not already secretly using them...lol.....

The current readily available high capacity super capacitors have a lower energy density and similar IR of the current lipos. Not a huge amount to gain by using them.

Maybe the potential is certainly there but until there is a retailed capacitor with a full datasheet and we test them on the track we wont know.

I don't think they will offer the energy density of Lipo and the voltage discharge curve is not as good when compared with chemical storage ie lipo.

They are currently being explored for use in conjunction with Lithium cells for electric vehicles.

Pretty much what bert is suggesting.

Correct, but I feel some racers will have access to the product long before we do...... Hopefully race directors will be able to level the playing field.... There is a guy using a similar product on airplanes mostly. Warthog power systems is his company, and if he gets access to those graphene supercapacitors, he can change the RC tc racing world for good....
