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.

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.

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:

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.

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!

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.

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.

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.
