Curious, why aren't you using your icc dodgeguy?

Anyone tried doing any 5 cell work on the ICC? on their website it says it will support 4-6 cell icc function

I am not going to be racing as much. So I do not need to have a high dollar charger for 1 race a month. Anyway it does not make my lap times any lower with the wc cells. Plus I am moving into lipo packs. And this can not charge them rigth now.

I don't think it should take long before the ICC can charge 5 cell packs. I have seen some team drivers testing with the ICC charging 5 cell packs. So I guess we will just have to be patient for a little while

Red face Shipment Received!

The Postal Service has come through. I received my repaired ICC today. I'm currently putting it through its paces to see how it functions. The firmware version is 1.06b. So far I have to say that I am pleased with the results. I'll post more after more testing.

I've been working with our 4-cell practice packs which are GP3300 cells. I have been using the ICC in the GP3700 profile without any changes to charge the packs. These packs are placed in the Tekin Battery Doctor trays for 24 hours before they were put away a couple of weeks ago. Pack voltage was low to start with on some of the packs but the ICC didn't error out on this. The 8th pack is just getting ready to finish and I have not had any errors in charging. 1.06b has all of the screens that 1.06 has. So far the bigest changes are the mAH count is closer for the pack as each cell peaks and there is not a re-peak charge. The one thing that I did notice is the external charger mAH count is not accurate. When compairing the 2 numbers between the external and ICC for the same charge rate and time, the external one is consiterably lower. As most will not be charging your race packs on the external charger, this is not a big deal. I'll be charging the IB3800 this Sunday. I'll let you know how that works out.

on there website

According to the 2007 rule change of the European modelracing federation EFRA, next year will see 5 cell racing take place. Hereby we would like to inform you that we will update the ICC charger to handle 5 cell charging. At the moment the internal individual cell charging tray only accepts 4 and 6 cell packs. We will release a new software update soon, together with a small and simple to install hardware update kit. As we are currently working on this, more details are not yet available. Of course the external charging output of the ICC handles 5 cell charging without any problem.

The Battery Manager v2 is already prepared for 5 cell racing. The previous version Battery Manager v1 can not be updated specifically for 5 cell packs. However it can still be used on 5 cell packs, the cut-off voltage per cell will then be around 1V which is actually perfect for the IB4200 cells.

More information will be announced soon!

hey B&B,

thanks for the info. can you comment on the temp detection on the charger?

are the readings on temperature more precise?

do your cells always peak because it has reached cutoff temp? or do they actually peak because they have reached the delta peak that you set?

thanks again.

I haven't watched the temps really close yet. So far the packs have peaked on voltage. I have switched from celsius to fahrenheit on the last pack for the night. It also is a 4-cell GP3300. Here are the default settings in the GP3700 profile.

Deltapeak: 2.5mV
Temppeak: 113 F
Min. temp: 102 F
Lockout: 60 s
4/5/6 cell: 4
Current: 5.0A

About 1/3 of the way into the charge and the cell temps are all in the 92 area. I'll know more in about 30 minutes.

Just got a bunch of cell temp and cell voltage errors. I stopped the charge and changed back to celsius. As soon as I could I checked the cell temps. They are showing 28 - 30 C or about 82 - 86 F. Looks like there is still a problem when using the fahrenheit scale. Its still charging currently.

Thanks for the quick replies!

Are there any "smaller adjustment steps for current, deltapeak and starttimer"?

If you can, check to see if the temps near the end of charging are precise enough to actually be useful

Sorry for the numerous questions, but you are the first one on this forum I have heard that have the newest version of the software

Here is some more information on the charge settings:
Deltapeak : 0.0mV ~ 4.0mV by 0.1 V increments

Temppeak: 0.5 C increments

Lockout: 0 ~ 300 s by 10 s

Current: 0 ~ 6 A by 0.1 A

I didn't get a chance to check the starttimer. I don't have a reliable external tempature measuring device. After the charge is complete, the cell temps continue to increase above 52 C. Touching them with my fingers and also the heal of my hand are not painful. They 'feel' about 110 to 120 F to the touch. I know that this is not an acurate measurement but it is all that I currently have. The other unit that we have is set to 118 fahrenheit and the cells are HOT to the touch. The pit next to us had a temp gun and it showed 145 F.


Has anyone tried Step Charging with the ICC?

Sigh, so the ICC is still doing the "118 F = 145 F" thing... sigh... 30 deg is enough to kill most things....

I have tried step charging... but i think something is wrong with that too.. the charger does not slow down fast enough ....

e.g. if you set:
#1 0 - 3000 mah 7A
#2 3000 - 3100 mah 0.1A
#3 3100 - end 5A

The charger will gradually go from 7A --> 0.1A.... but by the time it begins charging at 0.1A, it has already inputed more than 100mah, so it already goes to step 3...

But that's just my experience, maybe my settings are wrong.

The tempature differance that I was discribing was with our other ICC with 1.05b firmware.
