Yes I have found that it KILLS both runtime and voltage over time, you may not see the drop immediatly but you will eventually see it.

Run time stays very close between all the cells using this method. And the packs stay strong.

Now if you use the 030 by integy. Great discharger for another type of cell. But not for the IB cells.

I have not tried the 4200WC yet. But hope to very soon.
I agree with the above. Pulse after your run then Linear before you charge but, I would not go under .90v though.

Yes the 0-30 is NOT FOR THE IB cells. It is only for the GP cells. GP cells on the other hand LOVE to go down to 0v even dead short for stock racing.

The new generation of cells are WIERD!! Never tried doing it more than once. It seems like every discharger has al least one thing missing from it. Many have pulse but wont hold the cells at a certain voltage others will hold but dont have pulse. Or the display dosent give you all the infor. I am awaiting the specs on the Integy 90 tray.

if you have any ? that i cant help you with contact him

wish you show the pic of the batterie discharger you made its so
Ask and you shall recieve but, it's not actully a discharger. Its a tray that allows me to monitor cell voltage and temp without having all the clips attached to each cell. It also can be hooked up to cool the batteries with the fans attached in the back.

OK....
In my situation it comes down to this:
Is it better to equalize to .6
OR
not equalize at all?

you NEED to equalize, just be sure to charge imediatly

also, make sure you store the cells with 500 to 1000 mah in them

Can you recoommend a good discharge tray? I have the Tekin Battery Doctor which brings the cells down to .5 so this wouldn't be good for the IB cells.

I agree with mike. As long as you can set the cut off to .90v you should be fine.

I used the battery doctor on the my ib3800's and it worked great. I haven't tried it on my ib4200's. I bought a much more ctx a couple months ago. I've been using it now. I have been setting my ctx on liner .7 just before I charge my 4200's. I pulse discharge after running the packs at .90

I am not sure if you guys are understanding what I am saying.....OVER TIME bringing them down lower than .90v WILL degrade the cells. You will not see the results right away but they will eventully start dropping. The other trays out there will equalize the cells but, I would not recomend it. You may see benifits to brining the cells lower or even dead shorting them but you WILL damage the cell and over time (say 3 to 5 cycles) they will degrade.
