ib3800 vrs. gp3700
 

there both the same price from maxamps.com , but witch ones perform better?

Overall the 3800's show the best numbers according to radio control car action but the 3700's maybe a little more durable

If I was choosing I would choose the gp's just because of their reputation.

I thought Mike has got very good results with the 3800's.

I never heard about them not being durable..

@stampy, Mike can get you both cells, configured the way you like them.

Personally I run gp 3700's and they are fantastic. I get around 20 minutes of run time easily these days.

I prefer the IBC cells, but both are excellent.

Mike, what's your experience with those cells in a 'hot' setup?

also better than with the 3300's? I thought the GP3300's are the best for highamp applications (8XL on 20 cells)?

so theres no performance diff. between the to

I am talking about 70-80A+ applications here..

I have personal experience with running 6-cell unmatched GP3300 packs and 6-cell unmatched IB3600 packs in the same vehicles.
The IB3600 easily out-performed the GP3300 cells in the same application, for my use. I discharged at 10A to .9v/cell and peak charged at 5A for both packs when comparing.
My setup was a XXX-T MF geared 19/86 with a Lehner basic xl4200 motor and MGM 12012 controller.
The IB3600 packs consistently put out better punch, longer run-time, and cooler temps (on the cells) every run I compared them.

From what I've read and heard, the IB3800 are even better.

I'm not trying to say that Gold Peak cells suck now, but what I am saying is that I'll take the Intellect Battery cells for the same price every time now.

The only consideration for racers is the rules by sanctioning bodies. To this point, I don't think any R/C sanctioning body has approved IB cells for official races.

Hey serum. What i ment by durable is the ib 3800's are more sensitive to heat by soldering and they don't like the traditional methods of battery maintence(dead shorting and deep discharging)than the gp 3700's

I have had the same experience as Joe)Batfish). IB cells just seem to be better in high draw brushless setups (12 cell emaxx in racing conditions is pretty high draw). More punch than a comparable GP cell.

Deep discharging Nimh's is not reccomended.. it's only good for nicd's. Nimhs can die..

True, but some pro's consider it a way of wiping out memory and improving punch in gp3300's and rc car action also said it is not recomended for the same reasons but mentionde it because people are using this method and would ask.

Some of the best on-road carpet drivers in the northeast race at my local track and I can tell you that they dead-short their GP3300 packs regularly. This gives them more punch at the cost of reduced run-time. The drivers don't care about the run-time much since they never have a race longer than 5 minutes and GP3300 cells will give them nearly 10 minutes of run-time.
Generally they dead-short the cells as part of regular maintenance until the pack no longer gives them the punch they want. The pack will then either become a practice pack or they get rid of it.
Some of these drivers are sponsored and don't pay for their packs, mind you. I personally won't dead short because I want the run-time out of my packs and I don't drive well enough to notice the loss in punch from a well-used pack.

Yeah, well.. throwing 19 instead of 18 cells on your maxx makes a larger difference, and your cells will thank you for that! ;)

If they only grew on trees...

What is meant buy deep discharging and dead-short? I dont have a discharger so I run them until the maxx is sluggish, or almost until it wont on its own but it will still go.

I got GP3300's and I love them, although I havent tried the IB3800's or GP3700's. If either is better than the GP3300's i would be extremely happy

Your practice of running the cells until they only slowly move the truck won't hurt the batteries. Just let them cool before you recharge them (all nimh) for longest life. Both the 3700 and 3800 cells will perform slightly better than the 3300s, for a little longer.

A g-maxx related question Mike;

those 3700's are no perfect fit. How about the 3800's? are those the exact same diameter compared to the 3300's?

The 3800s are ever so slightly larger than the 300s, but seem to fit perfectly in my g-maxx chassis. The size difference is miniscule.

Okay, they are a better fit than the 3700's?

I have question as well. What about the weight? I know the 3300 is lighter than the 3700. What about the 3800 ibc?

You have the 3800's for sale? I need to get another set of batts. How much would I be looking at for a set of 3800's 14 cells with Deans?

The base matched sets are around $55 for a built 7 cell pack with the Dean's connector. The top of the line cells are a bit more.

Okay, they are a better fit than the 3700's?

I measured the 3300s, 3700s and 3800s diameter. The 3800 is .25mm larger than the 3300s, and the 3700s are about the same(within .02mm).

Okay, good info.

do they work on a gmaxx chassis with the CF battery holder?

give me a minute!

Tight fit! The CF straps work, but ideally the upper cf piece would need a slight trim(tight against a 3700 cell). I put 6 gp3700 cells in the truck and got the strap tightened down, with some effort. A small spacer on the fixed end(side without the thumb screw) to raise the strap and a slight trim of the upper cf strap would allow them to work perfectly.

Okay... THanks a bunch! i might order a few sets of those Ib's then!

Matched IB 3800 for you, Rene?

Don't know.. What are the options.. I thought they came in matched sets of 6..

I have 3800s -
