:woohoo:

How does your 4.4K cells compare to the IB4200's? Voltage and runtime comparisons would be great. Thanks

They hold their voltage a lot better than the IB's and runtime...........well that all depends on your set-up and driving conditions.

WILL YOUR 4.4K cells BE LEGAL IN '08?

I can't honestly say. It's not up to us as to what's legal or not. What would help is if you like them spread the word.

from the site There is a new player in the High Voltage Sub C Market. Meet 4.4K. Guaranteed 1.25! This cell has been specially designed and zapped to hold the highest possible voltage under load.


1.25v under what conditions? kind of an open ended statement!

Doesn't the supplier have to submit the cells to ROAR for approval? If so, it would be up to you to do that.

It's Not an opened ended statement it's a gurantee! Open ended would be they might? And they are based off of a brushed set-up but there are many running brushless and loving em'

Good question and it's one I can't honestly answer at this time. But I will Look into it. Time to make a call to ROAR.

Jason,

You need to submit to ROAR for approval, Dawn Sanchez (ROAR V.P.) is here quite a bit in the ROAR section, or just email them to find out how to submit for their approval.

I was recently reading the same voltage specs on your web site, and didn't see any further details on the voltage (Charting info)

So, I guess what the "OVAL" crowd will be interested in is, "Do they hold up to 1.25 volts @ a 35 amps discharge, and for how long?" Or something similar to that...

Jason -- you might want to get ahold of a CE matcher and cycle some of your cells on it and then give these guys some numbers.

This crowd is TOUGH and by no means ignorant of info.

Coming on and saying your cell is 1.25 guaranteed is one thing but to tell them it is under the CONDIDTIONS they run them on is a totally different animal.

You may already know this and if you do just ignore me, most do. :D:D:D

I guess I didn't ask the question correctly. What do the cells cycle at? I don't care what rate; 30amps, 35amps or 40amps. I just want to see average voltage, runtime, IR and cell cutoff voltage. I will compare that info to what I already know about the IB's. Thanks.

open ended by not stating the conditions such as charge rate, discharge rate, cut-off voltage, etc.

The IB's are 1.30+ when there just sitting there but that doesn't mean anything. Just looking for some specs like the others here have stated.

Thanks

I have been using MaxAmp Batteries for 4 years now. No complaints about their guarantee, their batteries and service. I have gotten a few non-performing cells over the years and replacements were on the way as soon as Austin, Clint, Jason or Josh have hung up the phone!

I too was a little skeptical about their batteries and their claims at first. I crunched the numbers... charge/discharge rate, runtime etc... that information was/is posted over at RCTech's forum. I finally gave up with crunching numbers and the arguing, now all I care about is how much voltage at 4/5 minute mark.

For the dollars spent, MaxAmps is the best bang for the buck! Buy a set and run them through the ringer. I am sure you will be pleased!

Dealing with the guys at MaxAmps via the internet/phone is like "looking a man in the eye when shaking his hand." You know you have an honest deal complete with a Guarantee!

Thanks Hick, that means a lot.

As for the cells I have the required paper work and have e-mailed it to the guys at the shop so they can review what is required by ROAR. We'll get what we need together and go from there. The IB 4200's that we sell are already approved.

...in the game of "VOLTAGE", especially in STOCK and/or 4300 Brushless Oval Racing - guys are very particular about their voltages...at least the guys who are mega seriously competitive.

These guys will spend in excess of $1,000 a year trying to find a pack with a .02 voltage improvement. So I think the basic questions guys are looking for for information here is ..."how does the 35amp discharge voltage compare on a MaxAmp 4400 to a IB4200"

Why don't you list any 4-cell packs ?

Couldn't tell ya... after testing the 3700's when they were the "newest gotta have", they were at 7.2/30 volts at 5 minutes - by this time I trusted MaxAmps I found no need to question their claims ... now I am switching to MaxAmp LiPo's.

Now, I am not "mega seriously competive"; one of my Teammates gave MaxAmps the 2006 Klein Winternationals one of their first "national" wins, then 2007 won in the RCPro Series Event, which he wouldn't have, had I been there!

Back at the 2006 Winternationals, IF, I know the meaning of IF, if my Teammates and I weren't so competative MaxAmps would have had the EDM title too! Between us, MaxAmp powered cars won every heat and the Mains. But the averaged mains won out! J-Rod and I have since discussed the room to race bit! He was as guilty as I! We still laugh about it. IF!

I don't think that is too bad for a couple of budgeted weekend (when we can) racers and a low cost, unlabled battery!

BTW a MaxAmp Lipo'd B/L LM TC3 whooped up on a bunch of gas boys a few months back, it wasn't pretty!

fla-racer57,

If your talking four cell 4.4k's or the IB's just call 1-888-654-4450 and talk to one of the guys about making a pack for ya'. And may I ask what you need a 4 cell for?

Jason,

1/10th OVAL racing is pretty much exclusively 4 CELL Nationwide...except for the areas that are moving into "LIPO" using the ORION 3200 Carbon style packs.

(You'll get a lot of OVAL people here on HOBBYTALK, even though this is posted in the GENERAL section)

Thanks SWT
Jason,
we use 4 cell in oval racing, both 10th and 12th scale. the only ones that use 6Cell are touring cars

Thanks Guys, it's good to know that. I've been away from the car seen for years. I went to the air............lots of planes to play with but now that the technology is getting better for the cars I need to get some new toys.

I've recently started running lipos but a requirement was the lipo packs had to be in an "hard" case configuration. That only limited to two, well now one manufacture. Do you plan on having a "hard" case type lipo pack in the 7.4volts for the touring cars?

I also run oval and very interested in a "4c" lipo configuration. The current 2c 7.4volt split pack would work fine if it was half the pack and 2c. 7.4 volts of lipo power in a brushless oval car or 1/12 onroad..now we're talking....

We won't be doing a hard pack. We looked into and there are more thing's that are so wrong about sealing up a Li-Po in a hard case than there are good things. For one cars/trucks run at higher amp draws than say most plane set-ups......this high amp power draw is turned into heat and at 125 to 135 degrees cells need to breath......open to the air.......otherwise they can and will in most cases swell or puff. Now take a sealed cell you can't tell accurately how hot it's really getting cause hey it's sealed up in a plastic case........H'mm wonder what it's gonna do when it swells from to much heat. And let face it I and many others have slammed li-po's into the ground at speeds over 60 mph in airplanes and have had many packs still work fine. Other packs have been damaged but never a fire. And it's not like your racing in a bed of nails either. Most cars/trucks the battery is in the chassis away from anything that could possibly hurt it. Another thing is that cased Li-Po's are harder to get into most cars/trucks. I think this is why you now only see one making them cased. I don't expect it last either. When running Li-Po's you need to know what your batteries are doing at all times and when cased you simply have no Idea.

Your answer is precisely why I don't care for Max Amps. Most of what you say isn't true.
The 3200 lipo pack from Peak/ Orion, are not in a sealed case. They are designed to come apart if the pack swells. They also have a board in them that the solder that connects the cells to the connectors, that melts if there is a dead short. thus stopping the voltage.

Having flown airplanes for years and having a Tower lipo get dented and having it short out later, I don't think that it is a good idea to proclaiming that it is OK to charge a pack that has had damage.

On oval cars and most sedans, the battery is on the edge of the chassis. That makes more pron to damage from a side impact. The bumper can and has hit packs hard enough to break the tape that holds them in. Offroad cars are different because the battery is in the middle of the chassis. To say that hard case's are not needed or a good idea is just wrong and misleading.

Also, there are at least 3 different companies that are offering cased lipo's.

I run an RDX PHI and those wont fit. I'm really interested in Maxamps 6000 and 8000 lipo pack. Those are higher capacity then the 3200 Orion I currently run.

See it worked on you............they've got you scared into buying em'.........I don't know where you got the Tower Li-Po? but I have smashed em' and had em' come loose and hit the prop.........no visable damage and yes charge and use again ........... and still using them. If a pack has a visable cut in it I don't use it again....common sense. But putting a Li-Po into a case that can't breath and then saying that the case will split apart if the cells puff? COME ON if they weren't inside a hard plastic case they would have cooling air and wouldn't puff. Oh and that board it can puncture cells I have had a specific brand do that. That's why most do not use the pc boards anymore.
You can keep trying to scare people into buying cased packs but you only making it worse for everyone in the long run.......your only draggin' out the "old Li-Po's are bad " battle. If your carefull when charging and don't over discharge you'll be alright with normal heat shrink wrapped packs. Heck more Nimh cells have burst as of late than Li-Po's. And all of what I said is true, I care about our customers new and old. I don't want them buying something that won't fit, has the potetial for over heating (oh but will split apart if it does........ come on!) and the possibilty of bursting when charging because it slightly swelled and didn't burst the case until it was to late.......

and I'm being misleading..........????

Jason,
If you want to sell to the serious racers you are going to have to put your cells in a hard case. Just check out the rules
This is just one set of rules ! But i'm sure ROAR, and the BRL will have something along the same guide lines

http://www.hobbytalk.com/bbs1/showthread.php?t=190999

Wow quite a discussion gentlemen, Bottom line NiMh cells/packs are just as dangerous as li-po's. Li-pos have gotten a bad rap due to a few people not taking care of them properly in their early days. The same people are the guys who have their NiMh cells dead short and explode, or think that they can charge a 6 cell pack @ 10 amps.. Bottom line is that this hobby takes a certain amount of common sense COMBINED with skills of many types.Mechanical skills, electrical skills, painting skills, just to name a few.The problem is that some people do not posess all the skills (or in some cases the common sense)NEEDED to enjoy a hobby like ours SAFELY.I am not saying that ALL of the explosions or meltdowns by either type of power source can be attributed to these factors, but I bet if we knew the TRUE stories behind them more than 80% can be attributed to human error in some way.I have read your discussion here and both of you bring up MANY VERY VALID POINTS.I for one am for caseless li-po's for 2 main reasons. Better cooling to try and keep from swelling the cells, or giving them a reason to swell, and so you can visibly inspect the cell BEFORE EVERY CHARGE. As for the better protection from impact aguement , although some what valid, We have ran bare Ni-cad and Nimh cells for decades and the risks associated with them are not really that different in an impact situation. Maybe people should start running cup style battery trays with bare li-po's for impact purposes if they are worried about the battery's location in the model.Hey then you could still inspect them for damage between runs and they would still get adequate ventilation out of the deal.Sounds like a no brainer to me fella's.. The deal is NEITHER of the electric power sources are completely safe, or idiot proof. Also those people out there who cant take care of NiMh cells properly HAVE NO BUSINESS dealing with li-pos simply because these are the people who will be most likely to end up getting hurt no matter how many safe guards you try and put there to keep people safe. Alittle off the subject, but thats why I despise the RTR craze with nitro vehicles so much. Yes its grown the hobby world drastically, but it makes it too easy to put some thing potentially dangerous in the hands of someone with no businness using it in the first place.PERFECT example Traxxass JATO RTR.. It does 70 out of the box. This is no toy obviously, but manny times I have seen them for sale on e-bay , listed by parents who are getting rid of it because their kids hurt themselves or someone else with it when the 13 year old who probally has no experience in modeling previously,was just playing with the TOY truck momand dad bought him for his birthday. pretty picture ,huh. well it happens in the electric world too guys, sorry but RTR's are going to be the down fall of our hobby.When people dont realize that even if its considered a toy by some , it is powered,and thats the key word here gentle men ,powered, it is powered by some source of energy.Energy in general DEMANDS respect. Without respect and an understanding of WHY you should respect it, Energy of any form will jump up and give you one hell of a reason Why it should be respected and handled like its dangerous,,,Because it IS!!!

I can make my own hard case out 1/16 or 3/32 sheet Aluminum. As long as it protects battery and keeps it inside the car - why care?

Besides it ain't the boom that hurts you, it's the debris resulting from the boom that will!

The sealed LIPO thread doesn't really belong in the MaxAmps thread, especially since we (The OVAL crowd) is moving toward a Single MFG. for the LiPo "sealed" battery.

This isn't something that is being done solely in the name of safety, but moreso in the name of 'control'. By controlling the battery to a single type and style of LiPo, it is hoped we can avoid a lot of the battery issues we continuously have w / multiple types, brands and mah ratings in the NiMh cells.

The 3200 Carbon Edition from Peak/Orion serves the purpose for MOST of the oval racers just fine..provides plenty of punch, power and run time to do 5 minute racing...or more. Plus, since only ONE MFG. is allowed, it's really easy to tech, and the voltage curve of these packs has proved to be so very close tolerenced, that from battery to battery to is virtually NO performance advantage.

Roflmao!

Fun!!! Ovals.

You know, for a support/promoting thread for a particular manufacturer, this is really a bad joke. I don't ever recall a manufacture's rep never answering any direct questions asked of his/hers companies products.

This all has the feeling of a company selling products out of the back of a van. "We have better products than anyone else, we just won't tell you anything about them". Nice motto.

You can't come here and say things that you can't back up with facts and photos. How can you say that you can slice'em and dice'em and they will be safe. Their "About Us" (http://www.maxamps.com/about.php) page speaks for it's self. Judge for yourself.

I am a supporter of Lipo and have been since the beginning of the year. ANybody here knows that. I think it is irresponsible companies that are the one's who are going to hurt lipo in the long run by posting info like you have done. It seems that they want to make money over safety. I bet if MaxAmps had spent the money on a protective case, they would say it is the greatest thing. Just "Common sense". It might be fine for plane's, heli's and off road not to have a hard case. But, not for cars that have exposed batteries. That is just "common sense".

As for the pack swelling, the two cells would separate in the middle and lift the two half's apart. Even if there were a small amount of swelling.

Here is pic's of a Peak Lipo that was in a car that had a speedo that went to a direct short. Good thing that the Circuit board was there. The pack was fully charged.

Come on man, just be honest about your product. If it is that good, they will speak for it's self.

This is a support form not a place to bash other companies products. Jason is here to help answer your questions about max amps batteries and support equipment. Please keep this on topic and stop this nonsense.

David

If this is a support forum, it is in the wrong section and violates TOS. I thought it was a discussion thread, That is what we are doing.

I'd be happy with the answer to the "numbers" question on the 4.4K cells. lol.

Like I said before I'm here if you have questions about our products not for a fight. If all you want to do is bewat up on me then fine go ahead. I came here to offer support to anyone that needed it for our products. I do this at several forums and I will be honest I have never been treated this bad before. There's a reason small forums stay small.....if any of you have legit questions you need answered feel free to contact me a jason@maxamps.com. I'm sorry to say but I'm calling it quits here because it's quite obvious that this type of badgering will never stop. Cola don't worry about it.

Thanks its been a hoot.

Jason,

I just think you came here without the answers the guys on this site are accustom to hearing from other MFGs.

Strangely, I know several of us have looked at your website prior to your posting here..and had very similar questions. Being "OVAL" racers we look for very fine numbers. (No this isn't a 100% oval site - but sometimes It seems really close)

OFFROAD RACING and ONROAD RACING is about turning left and right...and very rarely do you get 100% out of a battery. In OVAL racing, especially on a carpet track or other high bite SHORT track type of racing, you are dealing with guys looking at bettering their lap times by .01 seconds and look for EVERY oz. of voltage they can.

..part of the problem with this thread I do believe is its location. HobbyTalk does have a section for Product Support, where the 'general' sections are for more open discussions...and do have a tendency to get beat up a bit...

Chucking in the towel is not the way to win this battle, yes it can be won and these guys can be won over.

But you will not win them over with claims, but with numbers and PROOF.

In post #3 you stated "They hold their voltage a lot better than the IB's and runtime...........well that all depends on your set-up and driving conditions."

That in and of itself is a BOLD statement to make without the proof to back it up.

In your defense, you may not have had any idea what you were getting yourself into by coming in here and making that kind of claim. But like I said, these guys KNOW THEIR STUFF and will not be bluffed. These guys spend TONS of time and energy on their batteries, I know I used to. They have battery logs that would rival most scientific laboratories and their records.

If you claim the 4.4k cells are better and you know it. Show them the numbers on the equipment they test cells on.

This is a tough crowd, just put on some asbestos underware and enjoy the warmth. :D

*snip*

Asking who makes the cells seems like a support question to me anyhow!

Asking with what condition your 4.4k cells have 1.25v also is support related but you dodge them so you must not have come here for that.

thanks anyway!

I disagree.. In a five minute race performance power curve in NOT an issue.

The carbon Lipo-ion Peak/Orion packs has a lower burst rating then the Lipo poly packs. These Lipo poly cells are much safer to use and does not require a hard case around the pack.

The lipo poly batteries will soon be the norm in all power tools.

RPM,

We've already proved that DIFFERENT LIPOS perform differently...

HEAD to HEAD simply using the two ORION Sealed packs

The 3200 vs the 4800

One being a 2s 1p where the other is a 2s 2p, the VOLTAGE drop in the 2s 2p was a lot lower than the 2s 1p (You have figure it would be like running 2 of ANY type of packs in parallel, each pack only gets pulled 1/2 as hard as a SINGLE pack would.

With EVERYTHING else being the same - we were able to run well over a LAP faster w/ the 2s 2p pack and it had the ability to have geared it stronger..and gone MUCH faster.

I'm simply saying that the Orion/Peak Lipos are out dated...

Lipo poly is the new battery. :thumbsup:
