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)?

stampy · 08.28.2005, 01:50 PM

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

RC-Monster Mike · 08.28.2005, 10:20 PM

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..

crazyjr · 02:20 AM

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.
