Thats right, TEAM SCREAM RACING the winningest 1/18th scale national battery matching/zapping company is now diving head first into the MINI Z market. John Cravotta the owner of Team Scream has over 7 yrs of battery matching experience and has been racing for over 25 yrs, TEAM SCREAMS latest achievement came Thanksgiving weekend, winning the highly touted 1/12th scale class at the Cleveland Indoor Champs, there batteries are no joke. TEAM SCREAM will be releasing there 900mah AAA battery February 1st or sooner. I have personally tested these multiple times, and these are the fastest cells I have ever run. This isnt just another battery, I did say that these are being released by a battery MATCHER/ZAPPER didnt I?? (hint hint) These will be sold in groups of 4 and will come with TEAM SCREAM blue shrink with Black logo. Feel free to ask any questions you might have. John from TEAM SCREAM will be on here shortly....

Can you give/sell me a few sets so that I can test them for you?

I run Mod Oval and 2WD Mod in NNJ and I need extreme punch and speed.

So far I find Orion and Intellect batteries being the fastest.

I agree that Team Scream is one of the best, if not THE best in the high performance battery market these days. They also run a top notch business to match (no pun intended); but do you think these will be neccesary from a competitive sense?
Don't get me wrong -for a reasonable price (assuming they will be as good or better then anything else) I'd drop them in my Sinister just because they would be cool to have. :cool:
However I thought I read a blog from Cristian (at Atomic Mods) that matched packs would never really be needed for this scale because the cars get so much power now.

Then again....never say never right ?

That being said I better leave a few spots in my battery case JUST IN CASE ! :D

I agree with Christian on the matched packs not being needed for mod class though. Stock class if you can match punchy packs and high voltage packs it MIGHT make a difference. In modified it doesn't matter. You can't get the power to the ground. Unless foam tires and traction compound is allowed in the future. (I hope this doesn't happen)

But numbers on batteries can be manipulated and what you get from a matching company may not really reflect what the batteries really can put out. Zapping cells only lasts for so long.

I agree that a matched pack is not really necessary for a mod car. But for stock class or HFAY, battery power is speed... and will make a stock class car run with punch similar to a modified car. A good set of cells could mean the difference between winning and not with good competition.

I have spent a lot of time trying to make my cars run faster, when it has mainly been my batteries slowing me down. I recently picked up 5 sets of cheap Duratrax 750's. One of the guys that I raced with zapped a few sets. Those sets run quite a bit faster than the ones that arent zapped... I have more punch with them than any set of Intellects that I have had. Of course I know that they will not last as long since they have been zapped (a little less capacity), but I am alright with that races are under 10 minutes anyway. Now I have to sort through them and see which cells are good, and which ones arent... Its a long weening process. I have been waiting for matched zapped sets to come on the market for some time.

Daves cars allways FLY in the mains... and I know thats when he is using his matched sets. In practice and in qualifies, hes fast... but not nearly as fast as he is in the mains.

I just picked up a set of those Duracell 1000's. First charge they had so much punch that my car was nearly undrivable. Jonny from StaffordUK said he wa able to get 40min. of run time from one set. They just completed the 12 hour race yesterday but I haven't heard from him.

Anyway, my question is with this scale is it more important for batteries to be punchy or last long or both? I'm not really familiar with any other scale than this but I've heard of the benfits of a really good matched set of batteries. Will this company be making a battery pack that from the beginning of it's usable life will provide the same punch and longevity until it needs to be replaced?

Sweet Deal.....Team Scream..... John has always been an innovator doing what everybody else said wasnt needed in 1/18 scale as well. Next he might start tuning 130 motors.....(hint)
I believe the really fast guys now have some battery mojo and now even the common racer can get some......

I cant say how aaa cells react in the long haul compared to 2/3 a cells. I have been using Team Scream matched cells(3 years) and the packs I make up give me and my son awesome service.....We are not the fastest racers but we never have trouble on the electrical power side.....
Im sure if Dave G. is endorsing them (he has been secretly testing them)
the cells are that good....
Team Scream doesnt sell junk so the hobby has just went up a notch.....

I think Team Orion was or is making a set for the mini-z as well.

You're right this is a notch up for the hobby. I'd like to be able to purchase a decent set of consistent batteries and never look back. I think right now I'm running 4 different sets of AAA's. My latest is those duracell 1000's but since they are new they are the strongest but that has been the same with every new set.

JC@TSR
2008.01.06, 03:37 PM
Hi Everyone, well it has been a long time in the making but I did not want the news out until I knew these cells were the real deal. As you know Dave G has been running them and has had great results.

I will give some discharge data this week. The Intellects that I have been testing seems to have an IR of around 228. My cells tested in pack form were 204 to 201.

I am still working on pricing, as I want to make these affordable for everyone including Dealers. This is a new market for me and I will have pricing set soon.

I totally agree about the matching of these cells is not needed for the modified class. The stock class is what these cells would be best suited for. If you think about it though, wouldnt a matched pack provide more runtime over a non-matched pack, so wouldnt they be awesome in mod too? IMO a matched set of cells is better all across the board then a non matched pack.

TEAM SCREAM is the type of company that can always provide the racer the best possible products available. Consumers sometimes cant always get what a Factory Driver can, I do not hold back on my products because I feel you should be able to get the same quality product the TEAM DRIVER get.

Manipulating numbers is a big "NO NO" if you are in the battery matching business. I can not see why other companies would do this just to make a buck. It will take down your business in a heart beat if someone put it out there on the forums that false numbers are being provided. This is something have never done and will never do. The numbers that come off the matchers "are what they are".

If other companies want to jeopardize their business name with false data, be my guest. That is not where I want to go after all the hard work I put in to the sport I love. WCrotty I see that you are in the New England area just like I am. Mark Smyka just won the Cleveland Indoor champs with my cells, you can ask him about my quality if youd like.

If you have any more comments or questions please let me know....

John, glad to see that these are going to reasonably priced. I have one question: are these going to be matched/zapped Orion 900 cells, or have you outsourced cells from somewhere else? I'm very excited about these cells, they have been a long time coming for this hobby. Thanks....

Ancient Artist
2008.01.06, 05:48 PM
..thanks for the response John. Great point on where the value is on these batteries.
Regardless of the additional power they may provide, a matched pack will always give you greater consistency and run time then loose cells.
That goes a long when setting up your gearing,motors,etc in any class.

SING ME UP WHEN THE FIRST BATCH IS READY FOR PRODUCTION !! :D

CristianTabush
2008.01.06, 06:59 PM
John, these are definitely going to be a must for high level stock racing for sure. I know that you are just getting done with these, but what would be awesome is also a slightly lower voltage, longer runtime matched battery for modified racing. Higher voltage in these little suckers in mod is definitely a hindrance to performance. Great to see you are getting involved in this. Your brand will definitely bring more recognition to racing this scale. :)

Hi John,

Smyka is a great guy. I have raced with him for years.

I'm also wondering if they are repackaged Team Orion Cells or are they something new? I know when i was doing testing of intellect cells performance was dependent on the freshness of the cells (PN gets the direct and airs them to the states). When i was testing my Team Orion cells on my turbo GFX i was getting ~19.5 (195) for AIR 1.145 Avg voltage at a 6 amp discharge and a .9 cutoff.
This was without zapping the cells.

I can't wait to get a pack to do some testing.

Pulling some late nights to get the info up here for these cells. I also wanted to say these are not repackaged Orion cells. I have been testing AAA cells from a large amount of companies for some time now and found these to be the best. I have Orion cells coming to test against my cells in the next day or two. I will post all the data between the two cells when I get it. Hopefully my cells will come out on top. We will just have to wait and see.

It never fails, you try do something to better a sport and a huge company jumps in a spoils all your fun. That's the way it goes in this business though.

This is the first cycle and will post the 2nd tomorrow. I am setting up a new computer this weekend so I can post some charts to view. I will also test the zapped cells when the computer is up and running. The Orion cells and my cells look pretty close number wise. I did not fudge the numbers just to make it look like that either. LOL!

I will also try a 3.0 amp rate to see how they react over a longer discharge pattern.

I can tell just by what I see in these cells that a matched pack will be the key to longer runtimes and performance through out the race.

I am sorry for the delay, but I am having some trouble with the software install. I am working on it and should have it up and running this week. Sorry again. It looks like there will be a Ask Team Scream Racing Forum up soon as well.

JC@TSR
2008.01.21, 07:36 PM
Sorry for the delay everyone. Finally got the software up and running, cells are on right now and I will post the results from them tomorrow. I have been cycling these cells with a 6 amp discharge and a 3 amp discharge. The 6 amp data was posted and 1.12 to 1.14 with IR 17-19. The 3 amp rate gives more data as if you were in a race. The motors peak out at about 1-2 amps under the right condition. I am thinking of sticking with the 3 amp rate because of this. The cell discharges for a longer period of time as it would in a race and shows how it can handle the long discharge curve. I am doing this for the racers so let me know what you think. I do not mind changing something before they go on sale. That will be very soon now that I have the software up and running. I just want to stick to a solid system for matching these cells.

CristianTabush
2008.01.21, 08:42 PM
Actually John, I've data logged this and the motors peak at 5-6 amps coming out of corners. The average discharge for a mini-Z race is going to be in between 2-2.5 amps during a race. 2.5-3 amp discharge should be good.

It was a long battle with the software but I finally got running and labels printing for the cells I finished for Dave. I added them to the website on the Micro Cells page. I will make them available so you can order them now. They will not ship until FEB 2nd or the 5th pending on how many I can get sorted in to packs. The Retail pricing is $20.00, Hobby Shop and Website will be $18.00. We worked out the pricing after seeing the Customs charge I was killed on.

I had a chance to run a couple packs on Saturday night.

These cells are fast. Made my previous cells that I have been running feel slow, and I felt no slowdown during my runs. I lent a pack to my buddy Sai, and I think he used them for 3 5 minute heats without repeaking.

I have been using some Duratrax cells, zapped. They are quick, but they dont have much runtime. Rated at 750, but I get average 550mah discharge out of them (at 1A). I tested these cells, and all discharged about 850mah after the race night was over. The duratrax cells are pretty punchy, almost as much punch as the Intellect cells I have. They are great for qualifies, but I start to dump towards the end of the mains.

It is great that the cells are matched, so you know you will get a good long run out of them. I didnt feel that they were as punchy as the Intellect cells at the start of the run, but that quickly wears off after a minute or two. I felt these were as fast at the end of the run as they were at the start. Which is something I care more about than initial punch.

I was pulling past almost all of the other cars when I ran these cells in 015 class. When I went back to my other cells, I felt slow. And last week I thought those were fast cells. I decided to not use any comm drops, since I had more than enough speed, and it was much more consistant.

Great product Team Scream. I plan on getting a few more sets.

Wow, these batteries are awesome:eek: Even when I used a 7th tooth pinion in stock, when the track is best suited with an 8, I still had more speed on the stragihts than everyone else. I changed to an 8 tooth and the difference in speed was crazy!

I'd definately reccomend these cells for stock class. This is too much battery for any other class:p

i drove my new cells @kenon last night seems to have less punch than the orions (which is a good thing btw in my mod car) like driving with orions after the first 2 min.....
seems to last quite long except in the main last night the set that i used dumped on me at the 8 min mark , completely dead @ 10 min..... been charging @ 1 amp but it was only the first run with that set:o

Two more wins with these cells tonight. I only used them in the main, and noticed the speed increase over my zapped Duratrax cells. (015 class and Nascar)

Too much power for my stock class 02. I was trying the Lexus SC430 body today, and I just couldnt get it to hook up.

Grant, you have to be doing something wrong to dump these, and the BPs in 10 minutes. I get about 18 minutes of runtime with my MR-02 Pan Car and Touring Car and about 15 minutes with the AWD. I actually get 15 and 12 with Intellects correspondingly. You might want to try a different charger/ different voltage cut-off as your cells do not seem to be getting a full charge.

yesterdai i started to charge them on the lacross till it said full then i let them cool then put them on my indi 16x charger @ 1 ampthey all charged for another 10-15 mins
i got excelent runtime from all of my cells thank you cristian u were right about it not charging all the way...i guess the lacross chargers are not good enough for what im trying to do;)

Here is battery charging and care info I was going to post.

PERFORMANCE CHARGING

(1) Charge at 1.0 amp with a high end charger such as a GFX, LRP, Tekin Etc.
(Our testing shows that the Power X and Lacross style Chargers false peak cells.)
(2) Peak Detect setting is .30-.40 MV
(3) After Running your cells discharge them at 3.0 amps to .90 volts per cell.
(4) Equalize the cells just before you charge them for best performance.

CHARGE RATES TESTED

We have tested these cells at a 2.0 and 3.0 charge rate. I will do 4 and 5 today to see how they do. They handle the 2.0 and 3.0 very well, the only down side is the IR goes down and you loose some runtime. With 5 min races this should not be a problem.

STORAGE

I have left 8 cells sitting since I started matching the cells. The numbers were 1.25 and today they were 1.22 and 1.23 after 30 days of sitting. I would put a 5-15 min. charge in the cells if you plane on storing them over the summer. Just to be safe I would also check the voltage every 30-60 days in each cell. I do not see these cells self discharging from what I have found.

I will do my best to keep up with the questions. If for some reasone I do not answer a question fast enough please call me at the number below.

I got a set of the bats through rckennon before the ny race. I ran the cells
in my 2wd stock car and they ran great. (of course saying they ran great is always subjective).

So I tested the packs out on my matcher and i was very pleased with
the results.

cell AIR DisAvV DisTime
1 17.7 1.153 437
2 18.2 1.152 443
3 16.9 1.151 450
4 17.9 1.151 453

Now my best Team Orian cell i matched my self was.

1 17.9 1.147 444

most of them are in the 18.5~ for air and 1.147~ disTime 440~


Now this all being said. My Team Orion cells are getting better everytime
i run them and match them. I have not had the chance to run the team
scream cells many times to see how the number drop off or get better.
