Arun, how do you prepare IB3800 before charging them? Do you tray them down before charging?
I will try the profile that you posted next weekend. Not sure if I will get the packs before this weekend.
Thanks,

Some people are also beginning to dead-short for stock/19t much like with 3300's, but this is ONLY with the newest batch of cells. Apparently, there have been like 7 revisions so far.
Arun, that'll work. Yeah, he recommended the charging setup for my GFX. But for MMCM he recommend to ask you.
7 rev. of production in a few months not too bad. There is no marking, I guess..
I'll let you know in a week or so how it work
Got to give Kumpol a call, I need 1 more MMCM MMCM made my 17 months old (8 packs) working like they were just bought 2 months ago...
Thanks

This profile is from Ryan Lee. He set this for a couple people in 19T class at the Reedy 2005. And I found out this was very good for 19T class at the Reedy.

What does (Tn 48) mean
What does (10) mean
and was these CTX charge profiles for a battery than has been taken down to 0.0 Volts!!
Thank You all in Advance for all the Information!

Tn, means that 'Trickle - No', during CTX setup the trickle feature must be on the 'No' state, basically trickle turned off
48, this is the temperature at which the cells will stop charging if they get to 48*C before the peak detect activates.
10, this is the Mv value of the peak detect for the whole pack, 10Mv.
CTX charge is only for discharged cells, if u try to CTX charge a partially charged pack due to the 1st to CTX stages having long lock out activated theses partially charged cells may become overcharged, i do not think 0.0V is nesesserally needed the regular 5.4V discharge is fine. I think for best results it is best to tray cells to around 5.4V, then put straight to charge.

Stew

will it have any difference if i set it to be 03 instead of 06? it mean 03=0.003 per cell or for whole pack? thanks

Let me see if I understand this right.
MMCM delta peak setting is base on individual cell NOT the whole pack?
Because there is no possible way for the MMCM to monitor and taking the voltage sample for individual cell while we are charging the cells in series.
If 03 in the setting mean 3mV and in the set up menu when you tell the MMCM that you are charging 6 cells pack. Then the MMCM will do the calculation for you and monitoring 18mV NOT the 3mV
If the setting is set for 4 cells, then the MMCM will monitor 12mV.
Do I understand this correctly?

At the end of last page it says 03-99 MV/pack.
The setting is for the WHOLE pack.

That’s why I was just wondering. To me 3mV/pack seems a little bit too low. If I was to charging a 6 cells pack with 3mV threshold setting. Meaning 3mV divided by 6 cells = 0.05mV. Now that’s 50 microvolt per cell. Even we bumped up the threshold to 6mV/pack still that gives us 1000 microvolt. We will all have to have IDENTICAL characteristic cells in our pack. It doesn’t take much for a single cell to drop 1 or 2 mV during its peak. Its only takes 2 cells to drop more than the other 4 cells.
The step charging is pretty much guaranty 1 and 2 steps your pack will never fault peak. But what about the 3 step? So your cells in that particular pack have to be a top notch or a perfect matched, otherwise you might be having 2 bad apples out of 6 apples. That is if the threshold is setting TOO LOW.
Individual cell charging and monitoring system is the way to go I guess. MMCM is the way to go as of right now, I’ll experimenting some more on the threshold settings. In my opinion I’d rather cooked my packs then not having enough juice.
