Lol, you really must have graphene balls to make such a statement.

....thanks for the insult. When you start resorting to insults it just shows your case is loosing its credibility!

Let me re-phrase my original question just for you...

Is a lipo battery with all the benefits of graphene technology (added), a superior power supply to SMPS?

I have no idea what rob was talking about? Maybe he was looking to make sure that there is no libellous content that defames his business or something? I really don't know! e.g. their graphene batteries being just a marketing ploy when that is simply not the case.

 

I have actually done some PCB's for graphene battery project, they do promise some interesting future technology, especially battery powered devices. It is new technology though and there are many hurdles to overcome, like all new technology, stability, lifetime, how to reliably manufacture the product, safety concerns etc. etc. But power deliver for any circuit can be achieved with a SMPS, a LPS or batteries. It is down to the implementation of the whole power delivery system, not just what feeds the front end. I know of noise cancelling headphones with two small SMPS's inside the earpiece along with the electronics (one for the supply, whether from the battery (inside) or the tether and one to charge the battery when external power is applied) no noise problems, careful design and layout, filtering and shielding. SMPS's bad press comes from their early days, they were noisy there were problems, but over the years understanding of the problems and how to solve them have been developed. Such is their importance that all the main SMPS IC manufacturers now have teams and application engineers that provide recommended layouts, application notes and backup. There is no excuse for a sub standard SMPS where money is no option and room for components. On of the main components is the inductor/transformer here size does matter, mainly how large a cable you can wind with. Often due to size constraints (mainly) and sometimes cost, this component is less than optimal. This does lead to design issues, one is heat, with the high dI/dt smaller cable leads to higher dc resistance, which leads to heat, which leads to more dc resistance, which... you get the point. Resistance also leads to voltage differential and so on. LPS have problems, so do batteries, there is no free ride in creating the optimal power delivery system... PCB 101, on multi voltage systems the first thing you do is look at simplifying layout in terms of power distribution, getting clean power to any device is the key to optimal operation.

Libellous, they state they are LIPO batteries, how much plainer can it get.

There is a thread on a battery powered DAC that might interest you - it was active today.  I think @Norton just posted on it.

founder has asked me to give it a rest, even though I haven't threatened or insulted anyone. I think the founder has the wrong person as all I did was ask that question: "Is a lipo battery with all the benefits of graphene technology (added), a superior power supply to SMPS?" which culminated in 'me' being called an ignorant pig! I am not the aggressor in this case!

Please be careful what you say about hobbyking as they are watching this space. They may not like the accusation in a public place. You can of course 'PM' me with comments like that.

It would be great to have the entire conversation in pubic so the company can set any record straight. Only companies with things to hide want things away from public spaces.

I haven't seen any insults toward you. Can you please use the report post function to let me know what you think is insulting? I'm more than willing to be wrong.

Unfortunately, hobbyking have now forbidden me to act as an emissary for turnigy graphine batteries. i.e. I cannot 'feed' their thoughts anymore. Perhaps 'the computer audiophile' can invite turnigy to engage in an entire public conversation? I doubt if they are interested or unduly concerned.

The Turnigy Graphene series of batteries push the limits of battery technology by utilizing carbon in the structure of the cells. With the addition of graphene, the battery has improved attributes such as higher energy density, lower internal resistance, higher discharge rates, and a longer life cycle.

The same as I said above, with link: they have advantages and disadvantages, just like anything else (see link for discharge behavior, for example).

 

The same as I said above, with link: these aren't as advanced as the Samsung developments everyone is excited about that may be coming later this year.

Reading a lot of their marketing I would say they use the same marketing writers as Synergistic Research do...

A lot of prose and misleading content, such as the use of "nano tubes" instead of nanotubes... see my earlier post.

Anyway not wasting my time on a thread that has turned into a running advert for RC batteries, its becoming a bit of a joke. So many really high tech firms (as Jud has mentioned and I know a couple more) that haven't got the technology spot on yet being beet by a company that makes RC batteries... If they were graphene batteries then it would be big news and they would be boasting that they were first. Read some of the RC forums on these batteries, its interesting. Of course some real technical detail where they use the carbon and graphene would help the matter, maybe I should report them to the relevant advertising standards, that would be interesting.
