Yeah its funny that the Hype is so plain looking but is probably the best out of the 4. And then there is the MA pack........ Ill just leave it at that.

So, thats^ alright, but an honest comparison of packs, specs & prices isnt? Explanation required please as to why my post was deleted, not impressed right now... ( still havent seen any evidence to prove the 75/150C rating either on these MA lipos ). :no:

Believe
 

Neil you cannot honestly believe that we are going to acquire proof of this can you? I mean really? 150c honestly? I'm not falling for this. Ture 150c rating? Science fiction at best.

Exactly what I was thinking, good job! This should be stickied, and maybe mailed out as a brochure, or at the very least, included with all traxxas vxl vehicles.

I wonder how TP get the lightning power in the pack? Do you think they use a large funnel to gather the lightning? With the pack at the bottom of the funnel, of course?! It would have to be a wooden funnel as wood is the only material that could contain that kind of raw energy power (save for shrink wrap).

I will have to call TP and see if they will share their "lightning funnel" secrets with me. Hmm, I could use a funnel like that to harness the power of the sun too. The possibilities are endless. Sun powered blenders, completely wireless, just like my cordless toaster. Make a daquari anywhere. Just take a moment to let that sink in, amazing.............

Do we think Maxamps is actually a german guy who was some sort of physicist during ww2? Maybe he invented litium batteries while he was on an acid binge? Sounds plausible to me, given the large quantity of info that I found on wikipedia concerning acid binges. I have read that the number one user of acid happens to be televangalists. They use it to keep themselves up and creative during those long commercial breaks.

I am glad we figured all of this out. I was having a few sleepless nights, but a fair amount of halloween candy put all of these things in perspective and allowed me to think rationally. That and the marvelous post I quoted above. I can only credit my mother and the fabulous thunderbirds as my inspiration to finally find a use for stale bread.

That brings me back to the cordless toaster, I was having difficulty when using a conventional toaster while in the bath. Not onlt did I have to run an extension cord into the bathroom, but I also had to watch out that the toast or pop tart did not land in the bath after the toaster ejected it (upgraded springs on my model). So I devised a cordless toaster. Just cut the cord off, made it totally portable, you guys should try this, as good or better than when you made the switch from tighty-whities to boxers, its that good.

The number of consecutive "ha" sequences I would like to use to reply to that post would exceed the character limit for replies on this forum. :yes:

Exactly, thats why we all want some proof of the ratings; otherwise it just proves MA are full of poop and rely on gullible/ niave noobs & 12 year olds to keep them in business. :yes:

So judging from the graph that was posted at a 50 amps discharge rate are we expecting to see the same battery hold 487.5 amps continuous? Objectively speaking, I really dont think that battery should be tested with any higher amperage being drawn from it given the voltages that were shown. We all agree 50 amps is a lot. So we are saying an 10C continuous pack with bursts of 20C is more than sufficient for most applications at a 6500mah rating. Yet I see ratings of 25C, 40C and now 75C continous being advertised. I understand the need to post these higher numbers as I'm sure they generate sales, but eventually these numbers come back to haunt manufacturers in the forum posts.

Brandon,
You have a great attitude, and if you keep it up I believe you can the company you now work for some good. Any manufacturer that openly argues with potential buyers in these forums just does more damage than good. This is a tough industry to be in. I dont think I have ever tested a battery that has lived up to its claims in terms of advertised C rating vs real world numbers.

It basically comes down to one thing: The IR (internal resistance) of the cells.

A lower IR allows the cell to output more current, with less voltage drop. Period. No way to argue with Ohm's law. :smile: A cell with a higher C rating should have a lower IR than a lower C rated cell.

If there could ever be a standard rating for cells that would be it. IR @ 70*F.

If anyone sees a flaw in that plan let me know, because I don't see it right now.

Edit: For example, in order for a 975A current to even be possible with ANY cell, their IR can be no greater than 3.8 milli-ohms (0.0038 ohms). This is at the nominal 3.7 volts.

The only flaw I can see is that IR is not linear with current draw. It's pretty linear until a certain point (where the chemistry simply cannot flow more electrons), then IR ramps up heavily.

True, but if this rating system were actually adopted, you would see MFGs rating their cells at the point immediately before the IR started to increase- since that would be the maximum performance of the cell.

I am a serious buyer, if these batteries can in fact do a legitimate 75c continuous graph, these WILL be my next buy. What's the hold up?

All joking aside, I am disappointed in the lack of proof, as I would assume that a company would perform tests on a product they claim to have certain specifications. If MaxAmps had done this, they would have graphs before release (as they should have) and there would be no problem showing us them, but unfortunately I do not believe that is the case.
If an airplane manufacturer claimed that their airplane could hold 5 people's weight you better believe they'd have done tests to support that claim prior to releasing their product. It's just basic business principles.
I commend you for your efforts and the way you are handling yourself on these forums, Brandon, and wish you the best of luck, but unfortunately I think that Maxamps has a bad reputation with a lot of members on these boards and you might have a tough time convincing them otherwise.

McP is right. This is how I have felt about ma for a long time. Big claims with didly to back it up. To say 75c continuous and 150c "tru" ...... Burst would mean testing was done. But not for max amps they just pick a random number I feel like. I seriously doubt any lipo cell of this size will sustain a 475 amp draw for any length of time. Not that that is what we need but don't advetise it if it ain't true. In most states that is false advertising. I mean really the dude has had 14 pages and a couple weeks to quell the critics and what have we seen? Same old products and claims from the same old company. Not to mention the demographic of uneducated hobbyists they target I'm waiting for someone to be injured cause they overated their packs with no actual testing or proof. Some will say I'm being harsh but who cares put up or shut up that's how I roll if you say it's 75-150c let's see it you've had plenty of time to show us how you came up with this rating. Let's just hope it's something more than a bold faced lie.

Hey Guys,

Sorry I have not posted in a while. I have a lot going on right now. Designing ads, making changes to the site etc. Some videos and more graphs are on the way. I will keep you updated when I have them almost ready to go.

Thanks,

Brandon

Same Shit; Another Day. We heard that weeks ago... IF they were 75C you would have to test them to know they were 75C. BEFORE you market them and "Design Ads".

I haven't run the packs yet, but I will be sure to comment when I can do so intelligently. I have only been back from I-Hobby for a week and the packs have only been here for a couple days - still need to unpack the stuff and dig up my Eagletree for data gathering - but parts come first.
I don't have the equipment to test 75c continuous(nobody I know does, either), much less 150c - I plan on mapping voltage under load against a 6500mah Hyperion pack (35c cont./65c burst rated) to guage the overall ability of the pack. The fact is that even at 75c continuous, the pack would only last for 48 seconds before being completely discharged(assuming it could deliver 6500mah at this load, which is doubtful). The wires, connectors, etc. couldn't handle this load without melting, either. I am completely confident that the packs can't deliver 75c continuous, as the wire and connectors are a necessary part of any pack. I don't intend to even attempt to verify this absurdity. I do, however, hope to get an idea of the overall capability of the packs. If they can hang with the Hyperion packs (voltage at a given load), then they(the packs)will have earned my respect. Regardless of label claims, I am interested in any quality battery pack.

Well put Mike. I'm continually impressed with your intelligence and level headedness.

Go Monster!!:yes: Raaaaawr!!

Maybe just delliver some facts and the graphs everybody is asking for. What could be a better advertisment for a company other than their products beeing good?

So this implies there allready are graphs.
What ever they are worth (see the point I made earlier about graphs), show them to us.

If you don't plan on showing proof (don't have to admit anything in public, but be honest to yourself), you may as well save your time here.
I doubt you'll win any customers on RCM with your current delay tactics.
But then again, what do I know about marketing?
I'm just a customer...:neutral:

Sorry Brandon, as sympathetic as you were with RCCA, this is not it.

I think we need to give the guy a break, Im sure he is trying to get settled into his new job, as well as change the website, as well as designing ads etc. Im sure he is just doing what he is told. Fact of the matter is we here at RCM are just not their target demograpgic, we are too smart and we see BS from a mile away, so why should he be listening to our demands? I mean i bet 95% of us here would never buy a MA pack anyway, and i am sure they know that. I havent looked but i bet brandon and/or jason is much more active on the traxxas forums, RCU, RCTech etc than they are here on RCM because that is where their target demograpgic is.

Yes
 

YES but I bet most of us have purchased a Maxamp pack in the past and we are looking for some level of retribution in the way of them finally coming to terms and either admitting that these race ready packs are not what is bing advertised, or that these packs are finally up to par with the rest of the hobby. Either way we just want some truthful info one way or another. Could you imagine if one of our 1:1 auto makers handled their advertising like this?

That's exactly my point!
But why would he then be wasting his time here?
And yes, he shure has got a lot to do, but better do one thing at a time rather then 3 things at once. And keep in mind, he's the one promising graphs.

And please believe me, I couldn't care less what maxamps does or what der LiPos do. If I wanted high quality packs, I would simply buy SLS LiPos.
But I'm trying to understand their tactics here and just don't get it.
Promising results and not delivering them isn't going to help them (at least not here).
Claiming things isn't going to help.
Delaying us isn't going to help.
This way it's just a colossal waste of time, and that's something next to no company does lightly.:neutral:

Did you ever stop to consider the thought process behind the marketing hype?

It kinda reminds me of the behavior of some children.

Good Attention..........Bad Attention..........It doesn't matter what kind of Attention.............Just so I get Attention. :intello:

I do appreciate the Monster's input and do look forward to some Eagletree tests in real world conditions. It's the very same thing I was considering when I posted my offer. Of course, I didn't get any response to that, not that I was holding my breath.

I'm not holding my breath for graphs from Maxamps either. All that has been produced so far from them, is a measely 7C - 8C graph.

Which is something even the cheapest Lipo on the market can hold up to. Many CHEAP Packs would blow a 7C - 8C graph out of the water. So I wonder where my money will be spent, based on the presented information so far?

It only costs a few extra bucks to upgrade the wiring to something like 4 gauge wire and 8mm gold bullet connectors. Why is this considered so out of question to hobbyists?

lol, 4GA. The wiring and connectors will weigh more than the pack itself.

we were promised graphs plenty of times...

I see 1 graph that is not even a 10c discharge....

Seriously everyone take a breather.

Yes everyone is skeptical, everyone has to right to be.
Yes he should have posted graphs before selling.
Yes 75C is ridiculous.
Yes MA doesn't have the best ''track record''.
Yes Brandon has other things to do than deliver prove to some users on RCM about pack performance.

You guys are all grinding over the same stuff over and over and over and over and over again, it's getting old fast. Lets try and see if we can all manage to stop worrying about the MA pack and get on with other more fun things huh. When Bradon has the time to post up a graph he will. After we can discuss what's what but until than just chill.

Amen!

6mm wire diameter is really that bad? If you're running the high amperage that these batteries claim to put out, the wiring would be worth the added weight.

whiners:lol:

To me its simple. Until Maxamps can prove that there pack is even close to there claims they don't get my money.

I appreciate Mike stepping up to do his own tests on the MA packs vs some hyperions, this is the best bit of impartial testing you can hope for really since Mike sells many different brands, isnt biased towards anyones in particular. Its one thing for all of us guys to jump up and down about the ratings being BS, but a good comparison by a store owner will be sink or swim for MA- either they'll earn some respect ( pricing is still nuts though ), or be trashed by the whole internet once those graphes come out- long term results & testing will be important too however ( no good if those packs die after 40 runs like alot of cheapy packs are... ).

Ton of drama! I'm sure Brandon :whip:will find somthing to graph:oops:, and when Mr. Mike gets caught up from being away he will as well. I see no more reason to bash or ask untill one of the above has any information on these packs.:yes:

I am not active on other forums. Marketing Director for MaxAmps.com is a full-time job, so I just don't have time to be on the forums chatting away. With that said I am making an effort to get some things together and hopefully the videos will completed shortly and well as some other tests that I would like to share with you guys. You know, it's like one big MaxAmps.com party in here. So enjoy the weekend guys and I will get some stuff to you shortly. :party:

Despite what the graphs and videos prove(not going to hold my breath) I think the only way your going to win back the RCM crowd is free lipos for all members whom have purchased from MA in the past. You guys should have all purchases on record, so I'll be expecting mine some time soon. JK

Waiting patiently for you Brandon, lay your cards on the table and lets see what you got ?

The cool thing is that you have the power to turn it all around. I'm sure there are a few who will never forgive/forget, but the majority of us are just looking for the best battery we can get for our money spent.

I got burned by several early MA packs, so I haven't purchased more MA packs since. I still have purchased chargers, wire, shrink, etc from MA though.

Bring a pack as good as a Hyperion for a similar price, and I would be willing to take another chance on MA again. The way you are keeping your cool in this environment is truly impressive.

Waiting patiently for more info ... thanks!

Great point. C rating is almost meaningless with these higher ratings being swung around. Really what we are after is voltage at a given load. The higher the voltage the more power our setups will produce, the happier we will be. Look forward to your results when you are able.

http://forums.offshoreelectrics.com/...6&d=1288922163

Here's another big claim...

i cant see the image!

C rating matters... Higher c rating should indicated lower internal resistance. If that low resistance is there and remains the pack will have a long life and produce good power. The internal resisatnace tends to go up as a battery ages (goes thru cycles) and the higher the resistance the lewss power the batt will produce. So going with the highest c rated pack (as long as it is true) will have the lowest internal resistance and hopefully last that way. Plus if you paln to run a certain output (watts) a higher c rated battery will have more headroom than a lower on will, and should perform better and not be pushed as hard, and last longer.

So C rating matters. I would rather run a 1000c battery than a 10c if all other factors (weight, size, etc) were the same.
