Does the GFX have step charging? I didn't see any mention of it in the manuel online.

Besides the yellow backlight and different faceplace there is new software. The software allows variable motor run so you can adjust the voltage while the motor is running.

Differences between the two are that the GFX uses the same charging and discharging technology that is responsible for it being the industry standard in battery matching. The second being it does not have step charging.

Some pro's are running the Cell Master (or some other step charger) but EVERY pro has a Competition Electronics charger

So what are your settings for this charger? I currently have a T-35 (no GFX) but my settings are...

- Peak Chrg 6.0
- Trickle: N
- Long Lockout: N
- PK1 DETCT V .03
- TFLEX 1 N Level 3
- Delay Time1 60
- Charge2 Amp 1.5
- PK2 DETCT V .03
- TFLEX 2 Y Level 2
- Delay Time2 60
- Charge3 AMP 6.0
- PK3 DETCT V .03
- TFLEX 3 Y Level 9

I am considering changing it to the following...

- Peak Chrg 6.0
- Trickle: N
- Long Lockout: N
- PK1 DETCT V .04
- TFLEX 1 N Level 3
- Delay Time1 60
- Charge2 Amp 1.5
- PK2 DETCT V .04
- TFLEX 2 N Level 2
- Delay Time2 60
- Charge3 AMP 6.0
- PK3 DETCT V .04
- TFLEX 3 N Level 9

Can someone give me some insight is this looks good?

All depends on the type of batteries you plan on charging. Check out SMC's website for charging recommendations useing CE chargers.
For NiCAD batteries, those profiles are pretty good though I would bump up the peak detect to 0.07 - 0.09. For my GP 3300/3700's and my IB 3800 I would use neither of those charging profiles.

I always use linear 6 amps to charge with the long lockout feature on. My peak detection is 0.05 for GP Batteries and 0.03 for IB cells. Only peak once and run the pack within 5 minutes of peaking. IF I repeak (a big if) the pack it is only when the battery has to sit 10 minutes or more before racing, I will sometimes repeak at 0.01 volts depending on the temp of the pack. Never use Turboflex for NiMH packs.

After each run use the charger to bring them down to 5.4 volts at 35 amps (all my packs have been matched at 35 amps) and then use the Novak equalizing tray. Before each charge, I put the cells on an Integy 0-30 discharge tray for 5-10 minutes after the lights go out.

I'm looking to charge NiMH 3300 & 3700's. So would this be better?

- Peak Chrg 6.0
- Trickle: N
- Long Lockout: Y
- PK1 DETCT V .04
- TFLEX 1 N Level 1
- Delay Time1 0
- Charge2 Amp 6.0
- PK2 DETCT V .04
- TFLEX 2 N Level 1
- Delay Time2 0
- Charge3 AMP 6.0
- PK3 DETCT V .04
- TFLEX 3 N Level 1

Not sure how to turn off the second Peak Detect, does turning off the Turbo Flex do this?

This is what you want:

- Peak Chrg 6.0
- Trickle: N
- Long Lockout: Y
- PK1 DETCT V .05
- TFLEX 1 N Level 0

Normally in the charging screen, the charger lets you select how many peaks you want. It will say peak detect or somehting like that and you set the number at 1.

Your settings aboove will really hurt the NiMH cells in the log run.

Got it! Figured where it showed the number of peak on the main charger screen and while it wouldn't let me set the Flex level to 0 I was able to turn it off. Thank you!
