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!

[brainanator]

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

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?

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:

[JERRY2KONE]

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.

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!

[MindThoughts]

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.

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.

Seriously..... It doesn't take much to rotate those low compression engines

Actually since neither of those engines are boosted in any way, I would bet good money they are both 14:1 compression or more

[whitrzac]

*rednek* ohhh... impressive.... it started a big car engine... must be much moar better than other leeeepos *end rednek*



the only thing this proves is that you need 3-4-5 packs to do ANYTHING with...

[MindThoughts]

Brandon-
Are these racers using the 6500mah cells? Also- how many cells, and batteries are they using? for example, are they using Three- Four Cell Batteries all wired in series, Or?

Do you know the final Amps and Volts these batteries are providing to start these awesome engines? Great Video by the way. Truly awesome power :) I'll be very interested to know how many years these MaxAmps batteries are able to start these Drag Race Engines- As Well. I realize- only time will tell.

PS. Initially I had thought these guys(Drag Racers) were only doing this as a test to see if your batteries would start the motors. I didn't realize that these Drag Racers are using your chemistry batteries as a permanent starter battery, rather than using other chemistry batteries. I imagine these LiPo batteries also weigh much less than a quite heavy lead accid or ordinary battery which Drag Racers would otherwise be using to start their engines.

Note:
I understand and appreciate all the people that are angry at MaxAmps for past experiences that you had with MaxAmps that were very negative and you feel were never resolved to your satisfaction. I'm very interested in the stories of anyone that would like to talk about your exact and specific experience with MaxAmps. For example- How your lipo battery failed, What max amps said in response to your request for customer service. Did you have any warranty at that time(for example, the free 3year warranty is a new offering, in the past- one had to pay extra for this and many did not buy the 3year warranty). If you did or did not have this extra warranty- what was your understanding of what your warranty was and or should have been(if any)? And what did max amps do about honoring this warranty. Who was your contact person at MaxAmps ie Jason? And what exactly was said between you and your customer service representative? What was the final result? Did you feel the customer sevice you recieve was unprofessional and or rude? and if so, how did you respond to this- yourself? Did you report MaxAmps to the better business bureau, if not- why?

Did you ever use max amps again? if so, why?

Note: If This Post would be better suited for a new thread, Than by all means let me know and I'll start a new thread specifically for everyone interested- to talk about their MaxAmps Experiences- Both Positive and Negative- in the greatest possible detail- from beginning to end- Including why you initially chose MaxAmps in the first place. And also feel free to include what your best battery experiences have been in the RC industry and how this is better than your experiences with MaxAmps. Thank you for your interest.

Note: We do not need to limit this subject to MaxAmps- we can include all batteries that are considered popular or high end or at least expensive. Keep in mind that this thread has been viewed well over nine thousand times. Most of the viewers are people looking to learn and are doing research to help them decide which battery they will buy to race with or even to bash their rc with. Either way, it would be nice to help those seeking knowledge and insight- in their journey to learn- simply by stating our experiences in the greatest possible detail. Clearly and concisely- and simply. Thank you for reading :)

I am actually really surprised that, that hasn't already happened.

Hopefully someone will be able to fully test one of these packs and let us know what the "TRUE C RATING" is.

I believe for the most part that has pretty much been done. 75C continuous(10 seconds) and 150C burst(1 second) at best. Which pretty much tells us that the TURE rating of these race ready LiPos is 75C. Not bad in comparison to some of the others out there, but that 150C rating is nothing more than a marketing stunt.
