Default how do I charge and maintain NIMH batts?

Its been about 15 years since I charged and discharged batterys. I just bought the super mod IB 4200 6 cell batterys from team brood. I have a ICE intellipeak charger. The guy at team brood told me to charge the batterys at 6amps for mod motors and 6.5 to 7 amps for stock 19t motors. When I discarge till next time I race discharge them to 5.4 volts then before i charge them again put them on the integy zero discharge tray and drain them down to 0 volts then charge them again. My question is after runing the batteries do I let them cool before I discharge them. Also my charger has all these options I dont know how to use or if I should use them, like what is peak sensitivity and what should I set it to?what is trickle charge current and what should I set that to?what is top off charge and what should I set that to? what is the point of cycleing your battery packs?and what amps should I discharge at. the batteries say dis 35 on them. Need help please

first off don't discharge the IB"s down to 0 volts they don't like it. Set the delta peak at 3mv/cell or 18mv/pack. trickle charge is not useful for racing.
I wouldn't charge my batteries at over 6 amps unless its a serious meeting any higher and u are just killing the cells. Cycling can wake up old packs or give u numbers to refer later in the packs life so u can see how much performance they have lost. The Ice can only discharge at a maximum of 10 amps. The reason ur batteries say discharged at 35 amps is because that is what the are matched at. 10 amps will just take longer to discharge.

hope this helps

Another thing you can do to the pack is abou once every Two to Three races, discharge the pack at 4.2 amps, and the charge the pack at 4.2 amps. But, before you race with it, "BUMP" the battery at 5 amps.

I would not discharge your IB's below .90 per cell, or 5.4 volts under any circumstance. And yes, you can discharge right after running, but if you can, put a fan on them to help them staycool.
