Correct, but using so much advertising that it increases the cost of the packs is bad practice. If a noob only sees adverts for one brand, then who are they to know that opther brands are better value or better performing.

, if you don't like them then go by another kind or go buy some of those Hong Kong Zippies

MA lipos are from china, thats the point, they just assemble them in the USA. That doesnt fully explain the massive price hike though.

I have been running them for years and will continue to run them.

What vehicle/driving style/setup/ any eagletree graphes or comparative data with similar spec'd packs from other brands?

I don't know what the fuss is, they are still the same batteries they were a month ago.

Not according to MA, they suddenly have new cells that can perform better than anything on the market, though there is no proof of that claim.

I don't think anyone on this forum can tell me what CONSTANT RATING IS or STANDS FOR, because there isn't one RC vehicle in this world that has a CONSTANT AMP RATING????????

Planes, helis and boats pull pretty constant loads as they are at a constant throttle level for long periods during a run, that is why a C rating is useful.
The issue is that MA says a C rating has no use, yet insist their new method of rating a cell is better than the continuous method use for years, by every other brand out there. A burst rating is equally useless, as no R/C out there pulls a constant burst of current The point of a burst is that it lasts for 1/2 a second or so at most, where as the average current draw (achieved when full thorttle is hit down a straight for example) is the more is more useful to know; hence why a continuous C rating on a lipo pack serves more purpose than the burst rating, but also why its good to have both, as most lipos do.

Anyways, the C rating on a lipo is the level at which the voltage doesnt drop below a certain point at any given discharge rate- I've explained this countless times, with worked examples. The only thing in question is the voltage at whnich the lpo must hold stable for that given current draw, but 3.2v - 3.5v is a safe level- see the other thread that sproutted from this one regarding a petition for standardized ratings.

Are you from the traxxas forum by any chance?...

Mike,

Thanks for you posts. As you know, I have loads of respect for you and anything you are involved with. I really appreciate you jumping in here.

I did NOT start this thread. I am not trying to "sell" anything here. I was just trying to explain the new testing method and rating system that we are currently using since there seemed to be a lack of understanding with regards to why we would use the new system.

Some of you guys agree with it, some don't. You all will buy whatever products you want to buy regardless of what I say.

Donating a pack to someone here will do nothing to help explain our new rating system. We changed our rating system....not our packs. I am not here trying to "prove" anything. I just jumped in on this thread to help explain our rating system and why we use it.

If I was the thread starter and started the thread with "Why don't you all just buy MaxAmps packs because they are the best" then I could see the need for your negative posts. Some of the posts in this thread that have been deleted were way, way over the line. Frankly I get a kick out of some of it because it is very creative:)

If someone here wants to test a pack, we offer a 30 day money back guarantee. Feel free to take advantage of it if you wish and it will not cost you a dime. You might just like it and end up keeping it:)

Best Regards,

Austin Else

i think feathers got ruffled partially by the claim 'It will maintain higher voltage under load than any other LiPo battery pack on the market'. no rating system in the world... effective and accurate or otherwise... makes that true, unless you have something to back it up with. if you do - prove it and post your graphs with comparisons with other top notch brands, and i can guarantee just about everyone here will eat crow and buy a pack from you personally.

that is a false claim... and a misleading one, if you have no proof.

I'd be more than willing to kick in a few dollars to help w/ the purchase of this new pack and have it tested. It would really help to answer the questions we all have in regards to how it stands up to packs w/ known parameters.

If the test goes well, it would go a long way towards repairing the trust factor that (at least for me) is lacking in purchasing MA products.

I say we donate the test pack to the tester for a honest video recorded test
