MaxAmps Race Edition Lipos

[josh9mille]

The part of the test i found the most rediculous was the fact that they gave the turnigy pack a 5th place rating in the capacity test, when in fact it held 80mah more than it is rated for. The winner of the capacity test actually held 60mah LESS than it was rated for. Does that make ANY sense at all? In my eyes the Turnigy pack won that section of the shootout hands down! However the seat of the pants test the Turnigy came in dead last, but i would still attribute part of that to the low C rating and capacity size.

More than likely. However, they can only test what they are sent. Personally I think they need to in future shootouts set a specific # of cells, MaH, and C (even though this is subjective as we all know) rating so that its a more even playing field. Nonetheless, seat of the pants testing will always be subjective.

True, but BigSquid chose that 4500mah pack to test, why didnt they choose to test a bigger pack? HK didnt send them a test pack, im sure it was bought off their website just like everyone else buys them. Turnigy do have 5800mah packs, but i dont know what the c rating is on those.

Something just occured to me, maybe since all the packs they tested were hardcase, that that is the biggest hardcase pack turnigy makes? That would make sense. Now im going to have to go look and see......
EDIT: ok so yes that must be the biggest hardcase turnigy makes.

Actually I don't know. In at least the first two tests I do believe they were supplied by the manf. with the batteries based on their test vehicle. I'm not sure if they purchased this round or not.

Ah, yes, that would be the reason. I think I was more interested to see the graphs than anything. I would have preferred them do at least 3 runs per battery for the graphs.

Couple of you guys said that you would be more impressed if s standard LiPo for an RC car was used and not a larger brick pack. Well Big Squid RC actually did this back in June with one of our packs and it cranked over the car right away with ease:

Although starting s real vehicle does take alot of amps it is only for a second or two and then it can rest for minutes or hours before being needed again. In an RC car or truck we may not be seeing the 200+Amp peaks but we see an average of about 30 amps for 15 minutes with regular spikes in the 150Amp range. The battery is getting a good draw on it for the duration of a run, right to the cut off. Lets see a Max Amp pack take that abuse. My last MA pack that puffed was rated at 100A continuous 200A burst, I was getting bursts of 167A and an average over the run of between 25 and 30Amps.

Brandon-
How long do you think it will be until you can get the 75c Continuous Discharge Test up for us to see?

PS. Is there any posibility to have the Battery State 75c Continuous(Full Duration) and 150c 1second Burst. And to specifify that Continuous is for the full duration of the charge of the battery- and 150c is for 1second burst- Onto the wrapping of each lipo?

PS. Brandon has already stated that these 6500mah LiPo's can handle and are rated at exactly:

150c Burst for one second.
100c for ten seconds.
75c for the full charge of the LiPo.

Brandon- you must have done some testing to arrive at these numbers you gave us earlier in this thread. Is there any way you can post up the test that were already done which gave you these figures? By the way- you mention to me in a PM that you were having technical problems transfering your test over to a Digital Format(if I understood you correctly), But if you could even take pictures of different time frames of these test you performed already, and just post the pictures up- that would at least be something for us to look at. I think most of us would like to see your 75c Discharge for the full duration of the charge- Test. The 100c for ten seconds is awesome as well- The 150c 1 second burst would even be interesting to see. What are your thoughts on this? By the way- what are you using to do the 75c continuous discharge for the full duration of the charge?

I'm not sure, but I think he said 150C, 100C, and 75C in that order, NOT amps...Huge difference.

[MindThoughts]

You are right, thank you. I will edit/update the post with c rather than amps. I appreciate your saying something:)

Actually the comparison gambit has already been done in here somewhere. Seeing more updated experiences is always a good thing. BUT the whole reason this thread was started was because of the newest claims by Maxamps for this "True 150C" race ready LiPo. So until Brandon can cough up the promised tests, graphs, and results proving its claims, we will continue to demand some kind of results. Look this was never about saving their reputation. They are the ones who advertised this battery in the fassion that is is being portrayed and we would like to know if there is any volitity to their claim or if it was purely a wet dream trying to sucker more unknowing people into their trap. If you want some level of comparison done between the rest of the batteries available then start a new thread and do some poling. This thread stands as it was originally listed "MAXAMPS RACE EDITION LIPOS"

[padrino]

Using the way they market as insight into how ethical they are I expect the cell manufacturer probably doesn't even rate them as 75C (note MaxAmps points out it's the cell rating, not the pack rating) however MaxAmps is assuming something to allow them to take some of the liberties they do.

No one will draw 75C continuous for any period of time from a cell or the pack, they sell to the RC community so from their point of view it's reasonable to assume that as fact.

I'm sorry but this is geting stupid...

WE WANT GRAPHS!!!
nothing else...

[slimthelineman]

Hey he's back...... With more coments and nothing that was promised, like proof of the ratings on the packs in question. Whatever let them dupe the uneducated that buy their products. Sooner or later it will bite them in the a$$ and come full circle. Lying to your customers is a ticking time bomb. I know none of the other manufactures prove their ratings either but then again they aren't claiming 150c ratings either. I say go old school and hook a cell to a bulb discharger that draws said 150c or close to it and watch what happens. Bet they won't warranty it. Any company who offers a warranty but also has a disclaimer nullifying it is a straight up joke. Had a cell drop in my pack in the first month and was told (without any questions about my setup) that the warranty did not apply and I had to pay for the cell. No offense Brando but if the graphs and proof aren't going to be fabricated/presented as promised save some face and just stop posting. People here aren't going to buy your stuff.

I think he bit off more than he could chew with this one. We all know you just came onboard with MaxAmps so you are learning as you go, but this whole "true 150C" crap really stumpt you didn't it? How can I back them up wihtout looking like a tool? What that wrapping sholuld have said is (75C continuous/150C burst) plain and simple and that would have been great advertizing, but now you have to back peddle like crazy just to keep your head above water. anything else is just a lie. The most obvious test here is when anyone makes a mistake or mispeaks to step up and say hey we slipped up "disclaimer". This is what the truth is. Bamm done. But nooooo lets keep this lie going, and going, and going. This just drove your character and credibility right into the toilet. So I cannot wait to see the next addition of the R/C action magazine with puffed up hype about these cells. If this advertising continues with the "TRUE 150C" race ready LiPos I am done reading your magazines as well. Honestly it is so filled up with advertising crap that it is getting pretty boring anyway. But to post up an ad knowing that it is complete rubish is the straw that breaks the camels back for me. Sorry Brandon I have to give you cudos for stepping in here and taking on the challenge, but this is just plain sad. Pure Hype and nothing to back it up.

Jerry, I don't think it would be fair to say Brandon didn't know what he was getting into.

Ever heard the saying, "Birds of a feather flock together"?

There is a reason why the Maxamps section on this forum didn't last very long. Why are they not here anymore?

Brandon doesn't answer most questions directly, probably because he has to run back and forth, between Jason and Austin, asking what to say and such.

3 peas in a pod if you ask me. The marketing hype is BS and they are all full of it.

It appears to me they took a solid 30C cell and are trying to pawn it off as "True 150C".

But since the "True" C rating works with capacity, let's go with a 6500mah cell, then demand they set the LVC at 3.4 volts per cell. <------another ploy to dodge warranty claims.
