I am wrong about MaxAmps.

[lincpimp]

Well guys, we all know what I think about maxamps products...

I sat for a while tonight and though about alot of things and decided to make my first thread over at NK a positive one. I did not go into the problems I had with the packs, and the somewhat vauge customer service that I experienced. I chalk up half of my pack failures to my learning curve, and the other half to factory quality control issues. Keeping my "experiences" in mind, I decided to try to solve this issue by attempting to push education and realization, sort of looking at the big picture.

I still firmly believe that there are other lipos out there that can outperform maxmaps proucts at the same price. That is all I care about when I buy a lipo. My opinion there has not changed.

However it is important that Maxamps continues to make a postive improvement on thier products, as so many people rely on them! They are a big company that has a large segment of the land rc lipo market. They have a responsibility to improve electric rc!

They already kicked/Banned someone we know and Labeled him as a "Trouble maker".

This is strange, because in our motor winding discussions, I found this person to be one of the most intelligent and helpful people that I encountered on the subject.

Thanks for the Link, Linc. I will be following along with this to see how it "evolves".

I already see back peddling, arguing with ratings off misread material, and getting out the dictionary to see exactly what the definition of "Continous" really is.

I would LOVE to see an unbiased 3rd party conduct discharge testing of various Brands.

I believe everyone would be very surprised. Quality isn't always indicated by Retail Price or Marketing Hype.

That's funny, Linc. I just responded to your post over there not realizing it was you.

I really did like your post. I hope that it catches some attention.

Yep, I thought long and hard about how to appeal to everyone involved. I could just say that maxamps ratings are incorrect, and they need to change that before everyone catches on and decides to take their business else where. But I went for a more diplomatic approach. It appears that Jason takes critisism very seriously, and I did not want to appear to just jump on the bashing bandwagon. It is nice to hear that he admits to not having much if any experience with larger scale conversions. That is interesting, and makes quite a bit of his argument unfounded to me. I hope that maxamps starts to give some sort of suggestions for use with their pack descriptions. At least it would give them some sort of backup when they encounter issues.

This is yet another thread with Jason attacking someone for no reason at all really. It was bad enough that the site owner told Jason to back off.

So, I'm in need of my first Lipos for an MM5700. I plan to run it in the new Traxxas Slash.
What do I do for a charger an batts? I was going to get one of the combos from Max amps but I don't want a fire my first time out. I'll subscribe to this thread, hopefully you'll have some insight for me.

Hey Rob, do you want to run 2s or 3s lipo? I would say for 2s lipo a trakpower pack would be good, and for 3s lipo a neuenergy 5000 3s pack would be good. I have both and have had excellent service from both. Neuenergy also make a hard case 2s version of the 5000 pack but they can be hard to find. All of these batteries are available in the rcm store, as well as quite a few chargers.

I think Jason just doesn't like me.

When I met him at the Midwest Nats I recommended that he use a bigger battery for longevity and amperage overhead. He told me the pack was working fine and that he would continue running it. So, I got one of the guys (call him X) running his pack at the meet to let me strap on my data logger. A 20C cont. rated pack hit 3.1v/cell upon 1/10th sec burst at 17.5C- maybe the pack wasn't warm enough. The sad part was that X's pack was 2.5 times the capacity of Jasons, so I can only imagine how bad his pack was getting beaten during the run. I tried presenting the data logs to him on the MA forum, that didn't go over so well.

Funny, Jason really has it in for you John! Badger really put the smack down on Jason. I would not be suprised if Jason is removed from most of the forums he is on. I like his limitless knowledge on everything. I wonder how many different brushless/lipo setups he has done? That would be handy info to know when he starts running his mouth.

I'm still learning so be easy on me. I believe 3s Hard case would be nice. A GOOD charge also please. I only want to buy it once.

Link me up if you would.

My last few items on ebay are finishing up in the next few days so I'm just about ready.

Here is a good 3s pack: http://www.rc-monster.com/proddetail...eu3s5000car25c

Hi Guys,

Austin here with MaxAmps. This is going to be long but hopefully worth the read.

I just read through this entire thread. I hope I can share some insight with you that may change your mind about a few things or at least add some content to your discussion.

1. First off, we never rated a 15C cell as a 20C cell. The pack in the picture is a Tronics pack from at least 3-4 years ago. It was rated at 15C when we sold it.

2. In addition, we do not sell Tronics cells and have not for at least 3 years.

3. From talking with John, the MaxAmps packs that he has tested were not only very old packs that we no longer offer, but also smaller cells under 3000mah.

4. The rating systems for "C" rate varies from factory to factory. As a general rule, they are absolute "maximums" based on testing loose cells without wire, plugs, shrink wrap, and at ideal starting temperatures. The factories that we work with provide us with the C rates. We test the cells at those rates and post those rates on the site. With some cells we under-rate and with some we keep the same, however we never "over-rate" the cells.

5. I spoke with John yesterday. John is a great guy, however in Jason's defense, he is also our direct competition as he sells battery packs on his site. I don't think that was John's motive for all of these posts. However, I can understand where Jason would think that John's opinion would be biased.

6. As you grow as a company, more and more people attack you. There are more MaxAmps packs out there than the other packs you are referring to. Therefore based on percentages, there are going to be more "defective" packs. As a consumer, the grass is always greener.

7. There are tons of our competitors posting as "customers" and trying to bash our packs for their benefit. It happens in every industry. Both Jason and I have dealt with several of these folks and may be too quick to lash out and get defensive. I have talked with him about this and we are on the same page.

8. We are constantly improving our packs. New versions of cells come out all the time. A 1 year old pack of any of our cells is an "old" version of the cell. That is why I am sending out a new 8000 pack for testing against the "infamous" 6000 MaxAmps vs 8000 True RC thread that has been posted on every forum that I know of.

9. We pride ourselves on customer service, quality products, and value. There is no such thing as a "quick buck" in this industry. If you sell an over rated product then you will get so many returns, negative posts, and unhappy customers that you could not survive. There are 100,000 happy MaxAmps fans out there using our packs. There are 3-4 people in this thread bashing us back and forth that may not even be customers. The one I have talked to does not have any MaxAmps packs over 3000mah and showed a picture of a 3-4 year old pack, then acts like we rated it differently than what was on the cell. The other one is using out dated 6000 and old version packs to compare to a brand new 8000 pack.

10. Here is a fact: MaxAmps earned both the RC Car Action Readers Choice Award for Best Battery and I just got off the phone with RC Driver whom we also won the "Best Battery" award. Can all these thousands of readers just be getting duped into thinking MaxAmps is the best? Not likely.

11. We do our best to offer full time online support(Jason). Its not an easy job. I can assure you that Jason's heart is in the right place. I do not know of another battery manufacturer that offers this type of support. He is constantly having to determine peoples motives behind what they are posting and lots of time finds out that they are either a competitor or sponsored by a competitor.

12. I agree that the "C" rating system is not a good system. There is no standard and "C" rating is really meaningless. We are working on a system to better rate our packs, however without everyone using that same rating system there would be no way to compare one pack to the next. I think that it needs to have weight of pack, capacity of pack, voltage under load, and max temp and a certain amp draw. This is similar to the NiMH sticker "matching". That is the only way to get an apples to apples comparison.

13. We try and match up packs for specific vehicles and setups. That is 95% of the market. Our 3S 5000 is perfect for the VXL, our 2S 8000s are perfect for the Emaxx, our 3S 1550 is perfect for RC18T. The majority of customers do not have the ability to even figure out what a "C" rating means.

14. I guess I will finish up with this. We are the only company that offers a 3 year 300 cycle warranty. That is putting your money where your mouth is. No other manufacturer offers anything even close. We are always available via the online support and the phone to talk you through your setups. We also offer any configuration, plug, tap, wire, and sized pack that you want. Its guaranteed fresh within 3 weeks since we build the packs here in the USA.

What other company can you call and talk to the actual person that built your pack?

In the end I appreciate all of your feedback. It keeps us going and never settling. We are constantly improving our products, service, and systems. To stay on the cutting edge of this industry, we have to.

Best Regards,

Austin
CEO MaxAmps.com

Austin, glad to have you here to explain (defend?) yourself, and appreciate the post.

I totally agree about the need for a more standard C rating. As a matter of fact, there is a thread about this very topic here. I think that any procedure MaxAmps comes up with will be questioned. TBH, any testing must be with an impartial third party against other competing cells. That way, no one can complain the results of the test were biased...

[kulangflow]

Austin, I appreciate you coming in here also. I didn't intend for this thing to blow up like it has.

I appreciate the new 8k pack, and I look forward to testing it (as best I can) when it gets here.
