i thought trays that have a cut off at lets say .9, stop doing anything after they reach .9v per cell. so leaving them on the that type of tray does not do anything. Like the rayspeed once the .9 is reached, the relay switchs open.

the resistory type trays like the integy (octane) basically just hold the cell at 0v with resistors and just keep from cell reversal.

Yes-the resister trays holds at zero-but it takes them a good 20 to 30 minutes to hit zero-even if they were trayed to 0.9 on a NOvak smart tray for example. Thats why its safe to put them in the Octane for 1 to 5 minutes. Its a quick way to drop the voltage and equalize the cells.

What kind of step charging are you guys using? I really don't know what makes a good step charge, so any tried and true methods would be great. Thanks.

There are 2 ways to step charge (in my eyes)
Aim for run time, or punch


Im using the CTX cell master, and i have been step charging my packs
Using
step 1- 7.5 amps to 2200mah
step 2- .5 amp for 50mah
step 3- 6 amps till it peaks
peak setting 04 on the cell master

That setting gives me the both of best world for my batteries, Run-time And Voltage.

Does anybody have a good setup for step charging 3700's and 3800's on the ICE?

My current set up is:
7 amps to 3200mAh
.2 amps to 3250mAh
5 amps till a .012 peak detect on a Pitbull.

I'm thinking that the cool down stage might be a bit of a stretch. It does take quite a while for the second stage to get over and done with, and I'm wondering if bumping it up to .4 or .5 amps would be a wise decision.

For the IB3800's:

1) 8A until 3050mAh
2) .2A until 3080mAh
3) 6.2A until 4mV/cell (or 20mV/pack) for stock/19T
.....or
.....4.0A until 4mV/cell (or 20mV/pack) for mod

If you don't know when the next run will be you can substitute the following two steps for #3 above:

3) 6.0A until 3500mAh **with a delay of more than 10 minutes before #4
4) 6.5A until 4mV/cell (or 20mV/pack) for stock/19T
.....or
.....4.0A until 4mV/cell (or 20mV/pack) for mod

NOTE: You have to tray them first, otherwise they may peak in step #3 before 3500mAh. If you didn't tray them, then cut #3 off at 3300mAh.

What charger are you using? I have the Pitbull X3, so I am limited to three stages.

Ah. I forgot to add that I'm using a Futaba CDR-5000 and performing each stage manually. I have each of the six steps below saved seperately on the CDR and I manually change to each steps saved settings after the previous one is completed. Of course I have to set my cell phones alarm to remind me during race day, so as not to let any time pass between the steps.

More likely a case of not putting "all your eggs in one basket" > And this was the company that basically said that IB cells were not up to the task.
