Default charger/discharger questions

i know this subject has covered a dozen times, but i want to make sure i do not ruin my batteries. i just bought new IB3800. for a charger/discharger i use a duratrax ice and use a novak smart tray to equilize the batteries. would i be better off to get a integy 030 to discharge them at 30 amps instead of ten on the ice charger? if the 030 is not the right thing please give examples of what would. thanks for the help.

thats all your really need. 030 can be harmful to 3800 since it drains it down to zero volts. some people prefers higher amp discharge to stimulate racing amp draw . it also causes lotsa heat to the pack which can be a bad thing. just discharge your packs with the ice down to 0.9v/cell and equalize

the cutoff for 030 is 0 volts. it drains the cells completely.

030 does not equalize, just high rate discharge. I use it as well as a smart tray to do my batteries. I pull the pack as soon as the lights go out and then put them on the tray then charge them with my Pulsars.

My understanding is that when the lights go out the battery is drained to 0v. Right? Shouldn't you pull them off sooner to equilize at 0.9v?

If I were you I would do the following:

1. Equalize the cells on your Smart Tray before charging.
2. Charge on your ICE at 6AMPs or look for a good 3800 Step Charge Profile.
3. Discharge on your ICE at 10AMPS.

You may want to find an alternative discharger as your ICE will usually be too busy charging your next pack to discharge your current pack. I prefer discharging at 30amps so that limits the discharger options. The Integy Reactor 30 will discharge at 30amps and the voltage cut off is suppose to be adjustable so you dont have to worry about going below .9v. The MuchMore CTX-D discharges each cell individually at a pulse discharge of 30amps and also has an adjustable cut off (this is what I am using) only downfall is the price $200. You could also get a Turbo 35 which will discharge at 30amps but it is kind of big and $200+.

I don't really know where they are at when the lights go out but they are not at 0. My packs generally sit for a few minutes on the smart tray after I run them down on the 030. The 030 will take them to 0 if you let them on well beyond the lights going out but I never do that.

i was told that it takes 48 hrs on the 0-30 to get them down to 0.0. So if you tray them till the light go out that is not 0.0.

I usually use my 030 until the lights dim. Then I let them cool for a few minutes and put them on my Smart tray and let it get to .9. But I don't store them that way.
