Talking Yang?

Yang -
This thread is about IB3800s and GP3700s! Not your superior IB3600s!
Anyways, don't you have a PINK car to catch?

JK - Good input.
Test will be available soon.

Post Results for test Week 1

Used the same Spintech (don't care about the level of the numbers) on 4 IB3800s and 4 GP3700s.
All were ran on 05 xrays on the same track with my 8x1 motors geared the exact same way. Not exact but it is close. The numbers are following an actual 5 min race.
The batteries will be changed to the other car for the following series races.

All packs were charged from a tray at 5.5A with a 5mV delta peak on Competition Pulsars.

IB3800
1. 4229 mah @ 8.8V peak
RT= 164 V= 6.83/1.138 E= 33.6 Cap= 1461 IR= 53

2. 4205mah @ 8.87V peak (broke after lap 2)
RT= 600 V= 7.05/1.175 E= 126 Cap= 5334 IR= 50.5

3. 4230mah @ 8.83V peak
RT= 262 V= 7.33/1.222 E= 57.7 Cap= 2335 IR= 30

4. NA @ 8.51V peak
RT= 302 V= 7.34/1.223 E= 66.9 Cap= 2690 IR= 25.5

Averages of 3 full ran packs =
RT= 243 V= 7.166/1.194 E= 52.73 Cap= 2162 IR= 36.16


GP3700
15. NA @ 8.41V peak (broke during 6 lap main)
RT= 316 V= 7.45/1.241 E= 70.7 Cap= 2815 IR= 27

16. 3954mah @ 8.76V peak
RT= 192 V= 7.17/1.195 E= 41.3 Cap= 1710 IR= 35.5

14. NA @ 8.35V peak
RT= 228 V= 7.05/1.175 E= 48.3 Cap= 2032 IR= 43.5

13. NA @ 8.32V peak
RT= 223 V= 6.83/1.138 E= 45.7 Cap= 1984 IR= 48.5

Averages of 3 full ran GP3700 packs =
RT= 214.33 V= 7.01/1.169 E= 45.1 Cap= 1908 IR= 42.5

Averages of 3 full ran IB3800 packs =
RT= 243 V= 7.166/1.194 E= 52.73 Cap= 2162 IR= 36.16

Now these were two different cars with 2 different drivers. We will switch batteries around during the next round so wait for the results.
Meantime I'll cycle packs number 4 and 15 to go heads up on a constant load discharger.
The graphs will be posted.
Enjoy,
TEX

Results are in from the Vegas race and more than 50% of the A main cars used IB3800s.

IB3800 won the following classes.

1/12th mod
stock foam sedan
12th scale stock

They also finished second in Mod Rubber and second in Mod Foam finishing.

Team Associated tested both the GP3700s and IB3800s and chose the IB3800s due to there higher capacity and power.

Not to bad for the first major race for the IB3800.

I'm not that impressed with the IP 38's after watching almost every run that Toso did in LV. His packs dumped on him almost every round!! I know they are probably fine cells for stock but did not appear to be all that good for mod. I even heard of someone at the event running the IB 38's in 19t and having issues with them dumping as well. I would not buy them if I was running mod.

The IP3800 is a Grepow3600UP cell. It has 435-460 seconds of runtime at 30 amps. The IB3800s are true 3800 cells with runtimes of 460-500 at 30amps.

If someone dumped in 19t he either had a bad motor , a bad cell in his pack or his pack never got a full charge. You can run GP3300 and have plenty of runtime left in 19T.

Not trying to be pesimistic, but were the other 49%(give or take) running 3700's? That still means we are in a dead heat on which is better.

I believe the point Danny made was referring to the fact that thisis the first major race where these cells were allowed to run.

That typeof performance and that number of people using it for a first race is impressive...

Be careful in your pessimism of the IB3800's.....just because your preffered mather and/or sponsor isn't matching these cells *yet* that may change...

With the last couple batches of IB3800's many doubters have been converted and matchers who were swearing by the GP3700's have begun to shift their efforts to the IB3800's....

It looks like these cells are the real deal

Danny,

I would like to know what the life span of these cells are? You made a good point in the amount of IB's that did well but most of those guys are sponsored by cell matchers and they were most likely brand new, with great numbers, correct?

I am a privateer and I don't have a lot of money to put into cells 2 to 3 times a year. So I just need some input on how long I can expect them to last racing almost every weekend.

Thanks.

Some people are just scared of change and play safe in sticking to what they know.Im sure if you was given a free pack of the new IB3800 cells to try you would have a differant opinion to them! I myself ran the new EA IB3800 at the weekend for the first time and now il never look back

I think a big problem for me is that I still have a bunch of 3300 packs, and it isn't practical to change out chassis each time I want to use a different type of pack. It also is hard for me to throw down $200 for a pack that the company still has to tweak. I think it would really help the consumers out if you could do a trade-in type of thing, where you send in your battery packs, and get like 10-15 bucks credit for each pack, and then you can buy more battery packs of the new type with that credit and included money. Then they could rematch the cells, and sell them again for super low prices (but advertise they are used, and their condition can not be garunteed). That way, if you don't like the packs, sell them, and buy some of those super low priced 3300s. But alas, I'm only 16, and I don't know what I'm talking about.

47 IB3800 including EPIC3800
36 GP3700
3 IP3800
1 Yokomo 3300


This is what the IIC tech crew gave us for numbers. I think there is some mistakes in that count because there were 8 mains and the total is 87 packs. Maybe they counted the B main foam that was run at the same time as the A mains so that would make 90 cars. The cars that broke probably didn't need to be teched after the race so we don't know what they used for packs.

The companies who had a choice between IB3800s and GP3700's chose the IB3800's. Team Associated chose IB3800's and so did Trinity drivers.

In the end GP3700 still won some classes which proves that there cells are competitive. Our goal was to prove that IBs are competitive and we did just that.

If you have read some of the comments on this thread by Mr.Blonde and Adrian M and others you would think that IBs can't compete and only GP3700s have what it takes to be competitive but that is not the case.

I can't say that they will hold up for a year or more because they are still relatively new.


We have been running IB cells since the first part of June. So far we have not had much issues with them. They seem to hold up well when you take proper care of them. Just follow the guidelines we have on our website and they should be fine.

Racers need to rethink the way they purchase packs because cells are changing at a rapid pace. I reccomend racers only buy a couple of packs at atime and use them and so ifsomething new or improvements come along you can buy a new pack. By following this you will never be stuck with 10 packs that are outdated.

My concern is how the ib cells will run over time i know the gp3300's seem ok for almost a year of club racing. Any thoughts?

I can't predict the future. Based from what we have seen so far they seem like they hold up pretty well.
