MaxAmps Race Edition Lipos

[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.

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 thinking to myself, and I realize this info is already on the forum in several places, but why not turn this thread in to a more constructive discussion. Since there are alot of us still reading up on the tread, what lipos have you had good results with? Let's start a poll and get some real information out to the guys following this tread that are on the fence about their future lipo purchases. The hell with MA, let them fall where they may in the results standings as we are obviously not going to get those promised results. Lets spend more time promoting the good guys !!


My experience with lipos is as follows:

Great results with Turnigy for the money, can't beat them in my opinion and to all who might be looking for them, check out Hobby King, they now have a USA warehouse but there stock has been low for a long time. Even if you purchase them from another one of their warehouses, their still an excellent deal when you add shipping charges. I use these about 70% of the time. Have never received bad cells with purchase.

Zippy's are a decent value, I run these alot also except the cells don't seem to balance near as nice as the Turnigy lipos. Still a good value for the money. I have had 2 lipos show up with bad cells but they stand behind there product. These were both from the same order so probably a bad batch?

Thunder Power I use in my smaller vehicles with great success. I little more expensive but I get tons of cycles with these and they seem to have a high quality control as I have never had bad cells.

I won't comment on the flaming bricks as I have nothing constructive to say except I don't waste my money on them anymore after having bad cells several times, and they seem to puff alot more than any other lipos I have used.

I'm sure there are alot of people on here that use higher quality lipo than I do, so maybe you guys can add your opinions about the higher dollar lipos if someone is looking for a better lipo out there.

I've used Maxamps (when they first started up), switched to Thunder Power, and now I'm using Hyperion.

My experience with Maxamps wasn't very great. I bought over $1000 worth of Lipos and chargers (5000mah 10s), it was when Lipos were just starting out, in the world of BK Warrior controllers and Hacker/Lehner. I got half a run out of those packs. Then they puffed and Maxamps wouldn't take them back. I ended up disposing of them.

My experience with Thunder Power was pretty good, never had a problem with those packs, the price was about the same as other lipos at the time, They were a little larger than the other but gave good performance. My Dad now has those packs, probably 40-50 cycles on em with no problems so far.

Now I'm using Hyperions and I'd have to say they are the best on the market in my opinion. I'm using two 3s packs in series on my Savage Flux and wow do they have a lot of power! They are also significantly smaller than my old Thunder Power packs for the same performance. Not too many cycles on them right now but 0 problems with them so far. My next purchase will likely be Hyperions, but I might try out NeuEnergy, it depends on what the space constraints and such are.

I've never tried the Chinese packs such as Turnigy, but I have been tempted to get a few, and probably will for my cheaper stuff. Heard almost only good things from them.

Our 150C Packs
150C - Maximum burst rating without swelling or damaging the cell. This is a 1 second burst.
100C - Maximum sustained burst rating without swelling or damaging the cell. This is a 10 second burst.
75C - This is the continious rating that the cell can handle through the full discharge without swelling or damaging the cell.

Have a good one.

Brandon.

Wait a minute. I just realized something.
Any pack at 100c can only last 10 seconds. So shouldn't these packs be rated at 100c continuous? You think Maxamps would have figured out and advertise it as a continuous 100c pack..

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.

[thzero]

Who knows because not one LiPo cell I've seen, granted not tons, has ever been marked the way NiCd and NiMh are with the exact specifications of the cell.

Hey guys I think I have found a cheap way to test lipos and how much current they can really hold. I just tried a Diesel Glow Plug from a friends Toyota truck on my Turnigy 4S 5K 40C. With my clamp meter I saw just over 15A of current. I left it on for about 5min and other than the Glow Plug getting stupidly hot everything else was cool. I should have measured the voltage too but couldn't find my Fluke meter.

Now I know some might be saying "What's your point?" but this could be easy way to test what sort of currents lipos can handle. Just add a few more Glow Plugs in either series or parallel (not an expert on this) and then just see how the batts hold up temp wise and if they puff at all. A clamp type current meter would tell you exactly what sort of amps you are pulling and a simple IR temp gauge will tell you how stressed the cells get. Oh and also a visit to a wrecking yard to pick up some Diesel Glow Plugs. Maybe from a big truck they will be bigger and you would need less of them. What do you guys think? Possible?

Just use a bunch of the deans bulb dischargers they are 30 amp loads with 10 #1157 automotive lightbulbs. Wire a bunch in series and watch her glow. Kinda old school use to use them for ni-cd's and ni-mh packs but good size load for not much cash and real simple.
