Question about Charging on ICE (FALSE PEAKS)
I just bought a matched 6 cell IB4200 pack, and I ran it about 3 times total prior to today...So today was my race day, I charge it up for the first heat and no problem, after the heat I discharge with my Reactor 20 and then let it cool a little and throw it on my ICE charger, and after about 4-5 mins ice said that it peaked...I restarted and about 5 minutes or so later it did it again, I looked at the graph on the ice screen and noticed that there were a TON of spikes on it...It false peaked about 5 times during the charge...After the second heat and preparing for the main I discharged the pack again and then put it back on the charger, got one false peak after about 5 mins and then it finished up ok...Do you guys have any idea what could be the problem here, I tried my ice on other batteries in between and they worked fine (graphs were smooth) PLease any help that you can provide would be greatly appretiated

It is quite common for the ICE to misfunction
but if your other packs are charging fine then it must be something to do with your 4200s.
1 cell could be stuffed that screws all the rest and also the new intellects do not like to be discharged more than .9 v per cell other wise it stuffs them, have you gone more than this?

My two cents, I don't totally discharge my IB's between heats. I use the temp sensor and set my delta peak to top off at as close to 125 degrees as possible.(about 7mila amps) at the end of the nights use I discharge on my spintech battery manager. Never have had a false peak to date.Batteries are allways very stong for heats and the main

I didn't take the cells lower than .9, I used the integy reactor until the lights went then let it cool and then charged it...Hopefully a cell isent bad since I only used the pack 3 times...That would be terrible lol...I tried other stick pack 4200s on the charger in between charges of the matched cell and it did not false peak at all...Any idea? what I should do?

the integy indi isnt considered as an equalizing/discharger unit. You need a tray and use it before charging.
by the way the indi will put the voltage below .9v incase you dont know. i just use it for 2-3 mins. then continue the process on my equalizing tray.

I had a buddy of mine's brand new Ice do that the other week. We did a couple of things to fix it. First he was running the tamiya plug with the aligator clips and the large aligator clips going to the power supply. I go rid of both of those. The problem was fixed. He does not tray his batteries before charging and I think that is where most of the problem is. The sloppy connectrions just amplified the problem some. He now trays them and has no problems. So check your connections and get a battery tray to take each cell to .9volts. I've had my Ice for a year and have never had a problem, but I do tray my batteries before charging.
Hope that helps.

My problem is that the pack looks like this one http://www.horizonhobby.com/Products...rodId=SUM4200B
It has clear shrink rap covering the battery bars, do you guys think it would be alright to simply cut away the shrink rap? Thanks and please let me know what you think Jeff
Also do you think the Trinity DPD would do the job (the tray part) if I used that to get the cells down to .9 each(assuming if i cut the rap off the pack)? I am considering purchasing the DPD...

What is a good tray out there to use?

I think I am gonna buy the Trinity DPD, but for now would the ICE be any better to discharge at 10amps with? I mean would this be better than the indi reactor
