I have a question, I have some IB 3800's I've had them since September and they are running flat a few friends of mine suggested I cycle them on my GFX to bring them to life.


Now the question I have how many cycles per day and week should I do cycle the battery To bring some life back to them I just did one cycle and here are the numbers how can I tell by the numbers if is a good pack or a bad pack and what do all the numbers mean?

1st Pack
Peak Volts 9.15
RIR 141
Air 17

DCG Time 330
Dcg Ave Volts 6.95
Dcg Ave V1V 6.99

MAHR 3208
MWHR 22318

7amp charge
.03 Peak Detect
35 amp discharge

Second Pack
Peak Volts 9.33
RIR 136
Air 15.8

Dcg Time 366
Dcg Ave Volt 7.06
Dcg Ave V1V 7.10

MAHR 3558
MWHR 25147

7 Amp Charge
.03 Peak Detect

Any Help would be greatly appreciated

It's not really recommended that you cycle packs anymore, at least with the newest cells. Have you been equalizing the packs? I don't know how many runs are on your packs, but the runtime seems a little low for 3800s. Also, lower your charge rate to 6A. Also, how hot are they when they peak? You might want to lower the detect down to .02v as well.

Looks like it is time to replace them.

cycling wont give benefits. It'l just give you info about your batts.

anyway, after a charge discharge them at 35amps to 6v as a pack.. and then equalize them in your tray to 0.09v per/cell 5.4v as a pack. then leave them a day or two (longest storage would be 3-4days, this will lower the resistance of your packs and will accept more charge)

lastly, tray them again to 0.9v per/cell... and then CHARGE, 6.0amps .02v peak detect

I HOPE those 3800ib's will still accept 3800mah of charge.

I got IB's that I had since last year that are still takin on anywhere from 4100 to 4300 mah's. I do have a routine that I follow and maybe that is why my packs are doing so well. I don't run mod either so that could be another factor as well. I discharge after I run, equalize and put in the box till next time. I then equalize again then charge them. If sitting for longer then a week I will run them on my Spintec and Dyna Pulse before charging.

All good advice, but I would refrain from discharging @ 35A. If you're looking to see how the #'s compare to the labels, discharge at whatever it says. I never discharge above 20A strictly to keep temperature down.

I discharge at 30 as per the lable on my cells. So that could be why my numbers are staying pretty good that and I am not abusin them by running mod. I never repeak them either for I was told that it is not good for them and not needed. I get my cells from the site in my sig.
