Why discharge at 30/35 amps. If you train your packs to work hard or harder they will perform better than if you train them at a lesser rate. Some NiMh have no memory but this isn't true. When we match cells on the TM4s they will reach 180-190 degrees and they can handle these temps with no issues.

so which amp rate do we discharge at?at the moment im discharging at 10a on my ice,but as stated that is not good.should i discharge at 20A or 30A?im going to build a bulb discharger(or maybe a resistor one).im not racing in modded class.im mainly looking for long run times.thanx

If your not worried about power and only care about capacity then discharging at 10 will work for you. When I reccomend something it's always based on racing and racers typically want the highest possible power.

It has the step charge, which is a must for me, and it has more delta peak value selection. The Pitbull X3 can measure down to 2mV/cell, while the Advantage and Cell Master only go down to three. The discharge on the Cell Master is only 10 amps. If I need a 10 amp discharge, I'll run it in my car. All of them have long lockout, I believe. One thing that would be interesting to play with though, is the zero delta peak on the Cell Master. It's where if the voltage levels out for eight seconds or so, it terminates the charge. But when it comes down to it, the simplicity, cheaper price, and the high quality CE charging is what attracted me to the Pitbull.

Because of the CM's SLC feature, it utilizes lower delta peak values than other chargers. I usually have my delta peak set around 6mV (.006V) for a IB3800 pack on the Cell Master.
This is not the case for the Orion Advantage, though. It uses standard delta peak settings like the T-35, pitbull, etc.

was looking at getting some of these new 3800's, wondering if one of the matchers posting on this thread could give some insight on how many times per day you can run the new IB3800's without sacrificing any performance? If more than once, how long between charges and do you discharge before charging them the second time? thanks for your help

I'm just a mere club racer, but from what other racers have been posting the packs are actually better the 2nd time around, provided they are given ample time for cooling... But the times may have changed...

You can safely run a battery twice in one day....the key is discharging it correctly, using a good quality tray on it, and allowing the battery time to cool before you begin recharging.....
The IB3800 or GP3700 both can be used like this....
While I am sure you could run it a third time if there was enough time in between races....I would not recommend going over 2....

eddieo, thanks for the info, couple other questions, what voltage cutoff do you discharge the packs down to before recharging them for the second run?
Also, when i look at your voltage and runtime numbers on your website for the 3800's is that at a 30amp or 35amp discharge? appreciate your help

You absolutley can run them twice a day. I ran 12th stock Sunday and for the Main I let a guy borrow one of my IB's and he had his fastest lap-fastest run with it on its second charge and finished with mega runtime to spare. There was a good 3 hour or more rest for the pack.
