MaxAmps Race Edition Lipos

That battery brick, if in 4s config, must be something like 4p or 5p judging by the size. I'm going to have to call shenanigans on this one...

Let's say that pack is 4S5P using 5000mah cells. Let's also say it was created using 10C cells.

We have 25000mah of capacity capable of 10C. That's 250 amps continous with 375 amp bursts.

Since our voltage is a big higher than usual compared to a lead acid battery, the extra voltage will help the starter turn faster.

A 10C pack in this configuration will do the same thing as demonstrated in the video.

If the truth were known, they probably were 10C cells.

I'm not impressed AT ALL by this, since once again, the configuration is NOT revealed. The capacity is NOT REVEALED.

I'm ALOT more impressed with this video.

"Here's another battery cranking video - with one 4000mah 3s pack.

No BS with this one. Nothing hidden. The configuration is 3S1P and the capacity is 4000mah.

Ummm........Brandon. What is the pack configuration and the capacity in your video?

On second thought, I bet I don't get a freaking answer. Questions like this don't get answered because EVERYTHING is fudged!

WOW we are such a cynical group, aren't we? Why so negative? Maybe there was a set of wires hidden from veiw going to a pair of car batteries? Maybe that was the new Maxamps nuclear fusion race ready packs with True 500C cells? Maybe that was the Tooth Fairy's car?

That's awesome. And that fact that these are among the lowest priced lipo's in the rc industry makes this video all that much more impressive. It's actually hard to beleive they are really turning that motor over for that amount of time- with this little LiPo.

Ha Ha thats funny.What a crock of shift.

[brainanator]

yeah! so your packs have the equivlent of 5,000,000 HP right?!

I remember a while back we were asking for a vid of them starting a car, and now that we have it we are complaining? I dont get it.

You are right, we asked for it and we got it. I guess we just forgot to mention that we wanted to see a pack comprised of 1p cells used. The fault is ours for assuming that since they claim 150C (and starting a car would help justify that claim) that they would do so using a 1P pack. Looks like we need to start an RCM legal department so that all our requests are filtered through legal-ese to prevent loopholes. :sigh:

I think its becoming painfully obvious that Maxampa has no intentions of showing anyone that these cells can actually handle anything other than that which is already being done by their competitors, nor do they care which we can tell by the responses on this thread. As expected advertising TRUE 150C race ready batteries is an aborition or myth if you will. I think we have already established that these NEW miracle breakthrough cells are nothing more than 75C LiPo cells that some of the other LiPo suppliers have already been selling on their sites for nearly a year now. Using that specail wrapping with pretty flames, and slapping that 150C on the case was nothing more than a advertising stunt trying to get everyone over to their side, and I am sure that it will work for the average R/C hobbiest who do not know any better or care for that matter.

Think about it. Most of the people in this hobby are just happy go lucky people who are thrilled that someone loves then enough to have bought them an R/C in the first place, and all they want is a good battery pack that can make their new toy rip around the yard/garage, or parking lot well enough to draw the interest of the neighbors. A few of the sponsored R/C racers will use them because they will get them for free, and when everyone else sees them being used. Well we all know that most will jump right onto the band wagon and sales will sore through the roof. We are a very small % of R/C people who actually would like to see some level of specs to show exactly what these cells are capable of. DO you really believe that they care one way or another what we think? So lets stop waiting expecting that something will redeem their tactics and come to realize that Maxamps is still the same company it has always been. Money talks and BS walks. Life goes on. So until Maxamps has LiPos that are directly in line with all of the other battery suppliers (price wise) or we start to hear about good customer service where warranties are concerned I will go with whats cheap and easy to get. I cannot in good faith spend my hard earned $$$$ on products where the company uses unfair, shady, or deceiving advertising practices to lure in unwarry consumers. Thats just my two cents. You do what feels right to you.

Thats what I said earlier!

I'd like to see MaxAmps step up to the plate and at very least lay out the exact specifications, manufacturer, etc. of the individual cells that make up their batteries; just like it used to be with NiCd and NiMh cells. Won't happen, but would at least be a good start.

I agree with this comment, people make the assumption that cheap = poor quality and expensive means it must be good. What percentage of the population that uses RC is actually well versed in the industry, and has done their research etc? 5%?, 10%? I can tell you right now, Maxamps target market isn't us, it's the other 90-95% who think that fancy packaging, high prices and way out claims are the way to make sales, they're still in business so it must be working. Starting a car with a Lipo? I've started a 4cyl Focus with a 4s2p A123 pack with little dramas (makes a good "jump starter") once again, a youtube video feeding off assumptions.

I carry a 3s 5k mah 25c lipo around on my bike just incase I have to jump start it... The car starting thing is a bit lame... But there is no such thing as bad publicity.

Ok that makes sense, I didnt think about it that way.

IMHO they (MA) are not going to change and nothing we say is going to make them change. Obviously Austin has found a sales tactic that works (for now), it may not be honest and it may not be right but i hope he remembers Karma is out there, and sometimes it can be a real motherfunker!

True C rating and actual listed C rating are two different things- they are actually listed as 75C continuous & 150C burst; the true continuous & burst rating is much likely down towards 30c/50c....



@ Mindthoughts- you might wanna change your youtube message you left on that maxamps video- you were clearly far too impressed by that massive pack starting an engine, when we've already been over the issue; a dogturd could start a dragster engine, and it wouldnt use over $1000 worth of batts to do so...
