Now we are talking:)

ClodMaxx-

You absolutely have a valid point with regards to that statement. I am going to have my web guy change it to say "It will maintain higher voltage under load than any other pack that we have tested". Since we have not actually tested every single pack on the market, the way we have it worded now is untrue. I appreciate the CONSTRUCTIVE criticism. I did not realize that it was worded that way...

Put me in $20.00,
Time to put up or shut up, Lets do this test !!!!

Put me down for $10, I think this is going to be kinda fun. Wonder if the 30 day money back guarantee will apply to a pay that was "tested" in the way it will be.

Any reason everyone is determined to test this particular pack? They have changed the rating systems for all of there packs it looks like. If you got a smaller mah pack of similar rating, you would not need such large equipment to test it.

You are right, many of the ratings went UP. Here's another 60C (non burst) rated. http://www.maxamps.com/Lipo-2000-74-Pack.htm

Might as well go for 70C http://www.maxamps.com/Lipo-4200-74-Flight-Pack.htm

[Finnster]

If it wasn't so absurdly expensive, I would get this pack and test it in the same CRT.5 setup as I tested the zippies and the Neu 30C packs.

What is odd is that this battery looks exactly the same but the ratings are different (and seems somewhat arbitrary.)

Pack #1:# 2200mah Capacity
# 14.8 Volts
# 34mm X 99mm X 32mm
# 25C Constant(55 amps)
# 35C Sustained(77 amps)
# 60C Burst(132 amps)
# 220 grams

Pack #2

# 2200mah Capacity
# 14.8 Volts
# 34mm X 99mm X 32mm
# 50C - 1620 surge watts(110 amps)
# 220 grams

Both for $115ea. >_<

Which would be the more fair pack to test against do you think? I have an Eagletree and a radar gun to get real world figures as well.
It wouldn't be fair to compare against the 30C 2500 Neu pack, but the zippy pack I already have data for, and its last years zippy-h's anyway.

Neu pack #1:
NEU2100XP 4S1P

NEU2100XP 4S1P 14.8volts
1C Charge
25C/50C
$44.00

or
Neu pack #2:
NEU2100EP 4S1P 14.8 volts
1C Charge
30C/60C
$60.00

You know, I'm a small business owner. So what right? Well, I see this little debate as wildly amusing. Why? Because even though you guys have seeming good intentions, when it comes to "keepin 'em honest", It's stunning to me at what levels you will take it! Because to me MA is only playing by the same rules as everyone else. The difference is, they are still small enough to be accessible! Try blasting Integy for selling over priced JUNK, start ripping Traxxas and you'll be banned from their forum for life. Try attacking Allstate, State Farm, GM, Ford, Apple, Microsoft, and the list goes on. Do you honestly believe their claims, advertising campaigns, slogans, can be validated by consumers? Maybe or maybe not. I may have my opinion, but millions of other consumers will beg to differ. And those companies all operate under state and federally regulated guidelines! MA is operating with no real set guidelines, but believe that what they are doing is good. No where does it say that consumers have to agree right? We all have choices to make. The big guys are the easist targets to go after, and it's human nature to want to.

My point is this, even if you test the pack and it misses "your" mark, who cares because "your mark is your mark". Your method is yours, and theirs is theirs. Who wins or loses? Sounds like a lot of wasted time, ego, and posturing to me. Is it going to change anything REALLY? Maybe to you guys, but not them, and certainly not the majority of the buying public. Even if you went on a relentless smear campaign, people will look at you the same way many look at conspiracy theorists... Which is "I don't understand any of this, and don't have the time to find out for myself" which is exactly what the Govt wants you to think. It's too far fetched and complicated for me to prove or understand, so I'll continue being spoon fed what's easist to digest. Maybe that is what's wrong with society, but it is the way it is, like it or not.

Do you think RC Driver, XRC, or RCAction are going to give a rip what the boys at RCMonster said about MA, when a fresh shipment of brand new Lipo's show up for them to run in their test cars? NO! It's only going to matter to you guys, who aren't even hip to MA batteries anyway!

So no, I wld never expect Austin to send anyone here a free pack to test, because he doesn't have anything to prove to you really, and more importantly because it's pointless to. Win or lose, you will still lose and he knows it.

Frankly, I have better things to worry about then if MA is screwing me out of some continuous burst rates. I'd rather watch anything on History Channel, than to spend time worrying about a battery!

That being said, I'll gladly sit back and watch this episode infold, then turn out the light, and go bed. And mind you, I've never owned, and probably will never own a MA pack, because I need my Lipos in pairs, and just cannot afford those packs. But if people are buying the crap out of them, and the public perceives MA as being the best, then give the Marketing guy a raise, cuz guess what? Not every consumer is as educated as some of you may be on batteries, and people love to buy what is perceived to be the "best". And that is why the State Farm's, Apple Computers, GM's, and Honda's of the world survive. Quality is one thing, but perception is EVERYTHING.

Gotta go, time for Ice Road Truckers!

The point is we are not saying it should live up to anyone's mark or standard, just define and back up that mark. A blanket "we have the best batteries in the world" is fine, if can be proven true. If so, great. Do they have anything to prove to us? Not if they don't want to. They could have just scoffed at this thread and walked away. No, they chose to post here and then many of us responded. Yeah, those discussions can get heated, but that's the nature of the beast. "Can't take the heat, get out of the kitchen."

No, maybe not everyone is as knowledgable as some here, but for how long? BL is not exactly cutting edge anymore being made available for the masses at a decent price.

As you pointed out, many other industries have standards for rating and testing. Seeing a sticker saying "meets standards" would eventually be trusted and would let people know that the product is rated approriately with a common set of guidelines, whatever those may be. And many of those companies you stated are considered good companies because of their quality/longevity, not their marketing. Ford could say they are the most reliable car in the world, but repair shops and consumer experience will eventually tell the tale. And guess what? Consumers will eventually come not to trust them.

Let those in the know better than I decide which pack is to be tested and let me know were to send the $.

I'm in for $20.00.

You know, if the MA packs I had for some reason burst into flames, I would definitely say this thread wouldn't be here at all.

I usually jump on crazy claims such as a ESC that can do 400A to the one that states 780A. Can they prove it, no why, because it's impossible for such little devices to put out that kind of AMPs. I tell everyone if a ESC has a real rating use it a the max continuous burst which means that will be what you see on hard acceleration and that's all. Most ESC will average from 5-20A for 1/8 scale racing depending on the voltage and correct motor used (Gearing and everything else as well). Now for a pack to claim 60C surge, I'll use that as a max burst figure that's all even if it's a number I'll never see in my RC life time. After I get a project out of the way, I'll start focusing more on my full scale electric race car and I'll show everyone what a real cell that can put out over 1500A continuous and 2 second bursts of over 3000A looks like. Now this cell has a 2V cut off and it will discharge at 240A and hold over 3V at 90% DOD. The numbers mentioned of the cell are not false as it's being used by the military.

Prove it I want to see a discharge graph - lol

I will when the time comes. I am though trying my best to get 2 smaller cells and it's tough. I should just claim I do military work and see if I can get some.

Edit: I did actually let 2 members here see the datasheet.

It's true, I am one of those members, the cells he speaks of are something else. However, I believe Lipo cells are better suited because of significantly higher energy density, and we are getting to the point with these new packs (G3's, TP 40C, etc...) that the packs are not the limiting factor anymore, or at least getting close to what we can physically use. However, that said, it DOES NOT hurt, in fact I encourage it, to have higher C ratings (as most of you would agree) for the mere fact that the battery will run cooler, last longer, and increase system efficiency as a whole.
