I was really thinking that with his credentials at RC Car action he would pull through and give us something.

I really wish that RCMonster would let them talk for a few minutes so that we can get some of the information out of them. Every time someone gets on here from or regarding Maxamps we tear them to pieces. I want to hear their story. Are these new chemical compositions? New materials? New something?

Getting ready to leave for iHobby tomorrow so I have a lot to do. When I get back I will be getting some graphs and videos together to post for you guys. Thanks for understanding.

Is Mike going to iHobby this year?

If so, maybe he can bring some fresh Hyperions to battle with the new MA packs.

With this high C rating, will it be possible to run three Schulze 40.303s wired to ONE 42s1p Maxamps battery pack with no parallel cells? I mean, that's only 909 amps, so there will be plenty of overhead. Just curious.

Hey, I'm skeptical of Maxamps, not because the claim might not be true, but because they are making sales on a product that claims 150c before there is any published proof of it. That is bad marketing ethic that no 300C battery pack can redeem. In the hobby business, integrity is key. I just hope that Maxamps had proof of 150c before marketing the batteries to buyers. That's what matters most to me.

But if these packs are legit, it would be a great upgrade in the RC market. However I hold my stance: unless Maxamps had proof of the 150c rating before marketing the batteries, Maxamps is practicing dishonest marketing (and possibly false marketing if it turns out that the batteries are not 150c). See, it doesn't even matter if these packs can run at 150c. What matters is if they had proof of this before marketing the batteries to uninformed buyers.

When I make a purchase, it's the ethic I shop for first. Thus I stay away from Integy and other knockoff companies. Currently I stay away from Maxamps because my four 3s2p 8000mah batteries all puffed and failed, hopefully that will remain the only reason I stay away from them.

I am sure we will get a graph fro Maxamps. Why not? Only a graph. I can also supply you guys with a graph suggesting that my Turnigy lipos can support 300C discharge rates. I am very good at Power Point presentations.

What gets me is that , like sikeston34m has shown us, these cells can supposedly able to generate around 21 horse power. That is more than enough to start any diesel engine that I have ever worked on and they had a little bit thicker wires going to their starter motors than the 12awg wires that Maxamps use. About 3/4 of an inch thicker. Hmmmmmmm??????????

Nard Cox · 10.19.2010, 03:53 PM

Everyone take a chill-pill. Let Brandon work at iHobby and lets wait for the graph.

Yeah most of us, if not all, are skeptical but no point in dragging it out any more.

Brandon enjoy iHobby

Here we go again.

ZippyBasher · 10.19.2010, 11:19 PM

I have to agree with Moneybags^^^ if they were 150c capable and HAD GRAPHS or any proof BEFORE the Claim of 150c. Wouldnt they just post it and be done with it, while we sat back and drooled...?? I can post something on here in about 15 minutes...

One has to wonder what the priorities are for an advertising executive, marketing Director, and how the relationship is connected to being an R/C magazine editor??? All of that being said why are we the ones asking for this info? I am not trying to bash on anyone, but seems to me that this info should have been already advertised prior to the release of said products. This is quite confusing, and still I have serious doubts that their idea of 150c ratings will match up with what we expect as the consumer. I sure hope these graphs do not just show peaks up in that range which were voltage spikes due to sudden changes in current flow. I do agree that bantering Maxamps is quite pointless, but if this would have been handled correctly in the first place we would not be here scrambling for answers as to what this new product is truly capable of doing. Especially when the claim is 150c, which is well outside of anything possible up to this day in our hobby. In fact 3 times what anyone else has been capable of doing. So excuse us for having doubts and wanting answers. As the advertising marketing director I would have stopped everything on my plate to get this info out to the general public ASAP so as to get sales off and running immediately. Especially considering the state of our economy today.

So, give him a break? For what? Think about if this was your companies bread and butter? What would you do to answer these growing concerns in order to corner the market of LiPo batteries and help said company grow in these desperate times? The more I think about this, the more disapointed I am growing. In fact how long would you wait to get this info out to everyone? I wouldn't be able to wait one more hour before I had this information on the net and in my magazine.

_paralyzed_ · 10.20.2010, 12:28 AM

So what should the industry standard be?? Do I need to start a dedicated thread?? There is NO reason this can't become a reality.

Stop bashing start fixing!!!

I figure for every ONE person (meaning us here on RCM) that knows it is BS, there is 100 people that are stupid and naive enough to believe posted ratings. They will not have any problem pushing this product, there is a sucker born every minute, and those suckers buy MA and read RCCA magazine.

Welcome to a world with zero accountability. Nothing requires them to actually sell the product they advertise. If that were the case they would have to advertise the proof right along with the product. As stated above the sad truth is most people are dumb enough to think because they buy what's in the mags it's the best because the ads or someone said it was. Same old maxamps won't back their product with proof until someone calls them out. These guys should work for the government, they would fit right in. Preying on the naive and will continue to untill they are stopped. They had no proof of these claims before they marketed this product. The fact that dude showed up as we started to question the product is suspect alone. Not to mention if they had proof where the hell is it? If you had it already why wait. Only logical explanation is they are fabricating it as we speak. My guess is we will never see an industry standard for testing. There are no regulations in the industry and no one for the companies to answer to. Why would they standardize it? Then people would start to realize all the cells come from a select few manufactures and just rebadged by the different companies.

There are only a few amplifier manufacturers but there are standards for wattage ratings. They came about by customers demanding it. If one reputable manufacturer adheres to a standard they will quickly become the market leader and other companies will follow.

Well let's hope the RC industry follows suit. Not saying it's impossible, but unlikely. I will say it would be nice to know exactly what our packs are capable of. Personally I wouldn't buy one brand over another due to a c rating, rather on how it works in my setups. I've ran neu Hyperion thunder power maxamps turnigy Orion and a few others. For the money I will keep running the turnigy packs simply because they are super affordable and work just as well as the rest for me when I race. It will be interesting to see if this small industry adopts regulations on batteries and ratings.

I would say that if a fully charged cell is 4.2 voltsthen a good rating method would be a sustained voltage of 3.5 under load for 3-5 seconds to get an accurate rating.

Well, there you go. That's a start. We put a 5 second load on a battery and crank the amperage until it dips below 3.5v. That's an easily replicated test. What should the voltage be? I can't imagine equipment to test these would be that complicated? Like a reverse automotive battery charger?

johnrobholmes · 10.20.2010, 09:41 AM

paralyzed, I started a thread about lipo standards a while back. The ratings systems that cheap battery packs uses is very similar, although they like to see 3.4v per cell average, 80% of rated capacity at continuous rated current, no overheating, and no puffing. Otherwise, there is no standard.
