Default Proper IB4200 care

I've read many posts throughout this forum and have different suggestions for the IB 4200 care. (World Champion cells in my case). Here is what I'm seeing a lot of. Please correct me if I am wrong:

First time use, 'wake up' prep:
1. Discharge each cell to 0.9V
2. Charge it for 500 seconds at 6 amps
3. Discharge it at 30 amps down to 0.9V per cell
4. Let the pack rest a bit for it to cool down then it will be ready for a full charge.

Normal usage when racing the pack once per week:
1. Before racing, discharge each cell to 1.0V per cell
2. Wait 30 seconds to a few minutes
3. Charge at 6 amps with 0.02mv peak detect
4. Race
5. Immediately after the race, discharge it at 30 amps down to 1.0V per cell
6. Wait 2 hours for the pack to cool down.
7. Put 500 seconds at 6 amps back into the pack.

How does this sound?

REAL WORLD VERSION: I race at night and well it takes way too much time to go through what u posted but your 99% correct. Its .9v cut off and im not sure about the kool down times..

What i do: I race stock touring

Normal usage when racing the pack once per week:
1. Before racing, discharge each cell to .9V per cell using 20-30amps then your tray....(after all they where stored with charge)
2. i don't wait i don't have the time to spare
3. Charge at 6 amps with 30mv peak detect for 6cells
3b. repeak them as i always get nervous of not having them fully charged and its a good kick off the line!
4. Race
5. Immediately after the race, store it as is as the stock class dont dump the packs, if its going to be more then a week before i run again ill slap it on the charger for 200-300seconds. Some guys dont bother with the charge, but the IB self discharge so i charge them up the extra bit.
6. Store it.

Approx. how many mAh you got with this setting... ?
My charger (LRP Pulsar comp 1) is not a high-end one so I can't set it up using seconds .

Thx

LRP not high end? Puh-lease. It should display time elapsed during charge, stop it at 500 seconds. 500 seconds is 833mah.

You discharge on a tray (Rayspeed, CTX-D, etc)that will discharge the cells individually even though its soldered as a pack. You charge as a whole pack unless you use a Spintec.

Either you use the spintec charger or you can use what Hara did in the JMRCA race. Use 1 charger for a single cell, so if you have 6, you will have to need 6 chargers to charge a single pack...
