Now that the racing season is upon us I decided to start this thread to give some more info about the IB3800 cells and try to answer any questions about this cell.


Here are a few things that might interest some about Intellect. Intellect is a relatively small cell manufacturer that has one goal and that is to provide the RC racing scene with the best performing cells. The owner which also happens to be the top engineer really wants to make the fastest possible cells. This is the reason why SMC chose to become the IB agent for North America. The comittment that IB has at supplying us with the best possible cell is just what we were looking for. IB listens and cares about what we say which hasn't been the case with some other manufacturers that we have dealt with in the past.


IB makes me think of an RC racer. A racer will tweak his car to make it go faster and IB will tweak its cells to try and make them perform better.

I think its important for the racers to only buy a few packs at time this way if a major improvement would come along you would only need to buy a few packs of the latest and greatest.


Here are the specs of the top packs we have been shipping out the last couple of weeks.

35amps

400+, 1.185+ , 1.7-2.0

30amps estimated conversion

467+ , 1.195+ , 1.6-1.9


I will do my best to answer any questions regarding IB cells.

Danny,

Can you address the rumor about them only lasting 6 to 8 runs then falling on ther face.

I don't have a question about the cells. I would like to say the pack I bought has been great. And plan on buying more.


Jason Jackson

I think allot of the rumours come from some saying stuff that they heard from another and so on. We have sold thousands of packs and we have had a few packs that acted up but nothing out of the ordinary.

The key is to keep the peak detect low and some of the first people to get packs would try to treat them like GPs by using higher peak detects.

Danny


What are you using for charge amps and a peak detect on the Ib cells?


Thank's Eric

We have been using .02 peak detect with a 6 amp charge.

I'm sure as the season progresses more racers will expirement with different charge rates and may find something that works better.

As of now it seems like motor setup is the key to go fast with these cells.

hey danny whats up? Just woundring what the price of the 3800 are from you? 4cell packs

Thanks

I have over 30+ runs on my IB3800, they still hall the mail!!! no sign of fatigue what so ever, if anything they are getting stronger...
Nick

I have about 15+ runs on one of my IB packs and I have been beating it senseless just to see what would happen. The numbers to begin with on the cells were pretty low but it still cycles at 4.78 Avg. Voltage @ 30A. I have been treating it like my 3300s with a .03 drop back and a 7 amp charge and have not had problems. But, I may have just been lucky. I have done my new packs at 6A with the 0.02 drop back just in case.

I just recently heard from a fellow racer that you should store these with 200 seconds charge in them...even if only stored for one week. Is this advisable???

I have been storing with .09v/cell and than charging at the recommended 6a .02pd but also deep discharging on a 0-30 prior to the charge. Do you recommend this procedure?

can't wait to get some of these cells

You can visit Lefthander and RC4less they both carry our 4 cell packs and have just received fresh shipments. I think the price is around 50.00 per pack.

bruce at rc4less has 420 rt and 1.185 volt packs at 35 amps from smc....give him a call or email him asap! these are phat sticks and won't last long! tell him katf1sh sent you for an extra 10% added to your price!

i have 9 runs on my smc IB cells and i have ran them in 4 cell mod and 19 turn...i like these cells over the GP's i have not dead shorted them..i tray them before i charge them.....so far performance has been awesome!

danny you can go ahead and post the results from the vegas show last weekend.
mike blackstock laid it down in 12th mod with IB sticks in his car...that is 8 brutal minutes of racing...results looking good so far! smc 4 life peace out!

If you race every week there is no need to put charge back into the packs. By putting a 200 seconds of charge back into the packs this will make the pack get a bit warmer when you put it on the 0-30 and could possibly be good but i'm not sure.

6 amps with .02 should be fine. After a run bring them down to .90 per cell on a T35 at 30/35 amps. The next time you go to charge it put it on the 0-30 for 1-2 minutes then start charging it. This seems to work well.

Vegas was great race for IB because it was the first major race that we could compete with the IB cells and show there true potential.

We asked the IIC crew to look at each car after the main to see what type packs they had in them. There was 8 A mains and here were the results that they gave us.

47 IB3800/EPIC3800
36 GP3700
3 IP3800
1 Yokomo 3300

Since they ran the mod foam B main in between all the A mains and the last A main which was mod foam I think they checked the cars from the B main mod foam as well. So it should be a total of 90 packs but the guys who broke probably didn't bring there cars back to tech and this is probably why there is only 87 packs on my list.

I bought a few packs of IB's and noticed I loss about 90-100 seconds of run time after I deadshorted them.I built the packs put them in a 0-30 tray waited til they were down to 0 volts and cool then deadshorted them.All the packs lost 90-100 seconds of run time only ran 1 time per day so they never had a bunch of cycles on them so when I run them I cant make run time in a race.All the other numbers seem to be ok,cycle numbers @ 35.299 rt 4.80 volts 4.81 volts @ 1 volt IR62 Act IR 9.2.Im gun shy to buy more packs were never abused any theorys of what might of happend?

Thanks Andy

Andy
Think it could be something in the zapping process of the matcher?

Danny,

How often can you reuse these batteries? You always say not to buy many at once and I believe your stock team drivers get 1 pack for a major race and your mod guys get 2. I race 3 quals and a main on friday and then travel to another track and do it all over again on sunday (3 quals and a main). So for that amount of racing how many packs should I have and how should I rotate them? Also for a big race like Cleveland how many new packs should I buy and how should I use them, like what rounds and mains for each pack. Thanks for all your advice.

And sorry to ask these question in the oval section but I didn't see anything in the onroad section.

At a major race we use 1 pack for stock and 19t classes. The delay is so long at a maor race that the pack has enough time to cool down in between runs.

As long as the packs cool down they can be rerun 2 times per day without any issues. If you local race are ran failry fast I would use 3 packs. If the program is run slowly the 2 packs will be enough.

Some say it will shorten the cells life but the way I see it a cell has a certain amount of good cycles. So if you use 4 packs once per day lets say they may last 1 year. If you use 2 packs 2 times per day they may last 6 months so in the end it equals to the same.

Hope this makes sense.

danny, any comments on dead shorting before i wreck these new packs i just bought???

Danny
You mention running a pack more than once a day. I know with 3300's on the 2nd run typically voltage went up but runtime went down. Does the same happen with IB's ?

Here are my reccomendations on deadshorting. Some say they run better when deadshorted and others say they don't. One thing for sure is that you will lose 50 seconds or so of runtime at 35 amps. If I were paying for my packs and racing competitively I would take one pack and deadshort it and leave my other packs alone. This would give me the option of testing it for myself and see if I gain any performance advantage by deadshorting. Hope this helps.


On a GFX with 2.5 hours rest in between cycles the runtime waqs pretty much the same as the previous cycle. The pack went 409 then 408 and 4.70 then 4.71.

thanks Danny for the info.

I have 2 IB packs numbers were the same on the labels. I shorted one and left one unshorted and pulled identicle times in 4 cell stock, overall run was within a half second of each other on the track.

That will be nice if we don't have to dead-short these babies in stock class :-)

Thanks for the info Eric !

Jeff F.
Check out the TQ cells thread.
I posted the results of the discharge curve of the same pack unshorted and then shorted.

I wonder if it would have made a difference on the shorted test if that pack had been dead shorted right from the start, rather than after several cycles.

There sure doesn't seem to be the big voltage difference like we are used to seeing on the GP3300 when we dead short it.

I think that deadshorting doesn't realy make a huge impact on this cell. With reports of guys losing a 100 seconds at 35 amps I would say that it would be safer to not deadshort.

i agree i have reports and tested the latest batch aacwv 419 runtime 4.78 volts undead shorted!

Are you sure it is aacwv and not bacwv?

dave w - i thought you got rid of all your 3800's in favor of 3700's ??

Are you sure it is aacwv and not bacwv?

NOPE IM LOOKING AT THEM KNOW aacwv there truespeed :thumbsup:

FUSION is rumored to be starting 3800 s soon steve has convinced me thease are the cells to have im just not deadshorting them i see no reason too we are alowed to run them for stock if we feel we need to untill gp has a answer for the blue batt :wave:

NOPE IM LOOKING AT THEM KNOW aacwv there truespeed :thumbsup:

hehe ... my current batch is bacwv ... that's why.

We get a new batch of cells every 2 weeks or so and each one of them has a different code on them.

I think GP maybe able to come out with something to compete against IB but since it seems it's taking them a long time it must not be that easy. We have 100% confidence that IB will continue to try and push the limits of cell perfromance.

One thing I heard this week from 2 sources who get GP3700 is that the voltage has dropped a bit in the latest batches that just came in. Some may think that IB trying to tweak the cell isn't a good thing but atleast you know that the next time you need a few packs there will be plenty of good IB3800s.

Any recommendations on charging the ib3800's on an Duratrax ICE charger?

We have had good results using a 6 amp linear charge with a .02(20mv) peak detect for the entire pack.

what cuttoff voltage are you using?

.02(20mv) peak detect

do you treat the 3800's any different than you would the 3300's??? and what does the term intellect mean on these batteries??

thanks
Jon

What about maintenence zapping..are you guys doiung that as well like we did with 3300's??

Intellect is the name of the manufacture, like GP was for the 3300.
Charging is different then the 3300 as in the drop back is .02.

Danny,

Is there a break in period for these cells? Like they are best after the first couple cycles are always the same. If I buy new packs for a big race should I cycle them before I use them or just assembly and use?

Also with all these different types of trays out there do you think there is one method that gives MAX PERFORMANCE over the rest? Thanks again for the advice.

I think that the first run on them is not that great. They will run well but not show the full potential. After that they are fine. I really like the Integy 0-30 because it's very easy to put the pack in it and it discharges fast and is almost impossible to get a bad contact. I reccomend you put your packs in it for 1-2 minutes before you go to charge it. This has proven to work real well so far.

I would like to get some feedback from racers on this forum. A few months ago we decided to stop matching the IB3600 due to great voltage and capacity of the IB3800. It seems that some racers don't mind the lower capacity cells like the GP3700 and IP3800 as long as the cell has good voltage. As a racer myself I know that in most classes a 3600/3700 has more then enough runtime.

We have asked IB to put the same tweaks to the 3600 and we will consider matching them again. We just got some cases in and they look real good and best of all the price is lower than IB3800s.

So my question is should we match these up and would you guys consider running this cell ?

The advantage of the IB3600 is that it's lighter and cheaper while having high average voltage and low IR. I will try and post a spec sheet soon.

The street price of our 6 cell IB3800 is 69.95 and the street price of the IB3600 would be 49.95 for the top voltage cells.

Danny, While oval racers may not want to lose the run time (even in stock) I think they would be popular in stock touring car and stock/mod racing in off-road. I know that I would rather have a lighter cell in off-road as I (and all off-road racers) could stand to lose a few oz. while run time is not even close to being a problem.

I would have IB keep making the 3800's as good as possible. I can't believe that the 3600's will give you that much more voltage then the 3800's and will also keep everything simple. If you have half the people buying 3600's and half buying 3800's I think it will be more of a paine then anything else. The price diff would be nice but hopefully if IB is only worrying about one cell the prices will go down.

Just a thought.

Thanks for your inputs. I know for other classes than oval they will be great due to the lower weight and lower price. Actually the IP3800 cell which has similar capacity as the IB3600 cell made me think of reintroducing it. If racers like the IP3800 cell they will most likely like the IB3600. If we can offer a competitive matched pack for the budget minded racer it would be a good thing to do.

IB will continue it's R&D on both cells so this will not creat any issues. In fact there latest tweaks have been applied to the 2/3A IB1200 cells.

Danny , What Has Been Your Experience On The Gp3700's I Notice That The Pack Of Gp3700 And Ib 3800 Is That The Ib Had About 40 Seconds More Runtime But The Voltage On The Gp3700 Is Way Higher 1.193 Versus 1.172 Is That A Pretty Common Scenario For The Two????

Rick K.

1.172 @ 35 amps is most likely 1.186 or so at 30 amps. The lower IR of the IB cells makes for more voltage upfront compared to GP cells. The latest IB batches have been real good voltage wise.

Our 4 cell packs are now shipping out with 1.195+ @ 35 amps.
