Fred and Mike have both done their homework very well. Cells today are so sensitive to changes that you might not get consistant results. (IE summertime cells peak out lower voltage vs Winter cells peak out higher voltage). Guidlines for IB3800's were .7 cut off for equalizing. .9 for pulsing. I think that you will find with time that .9 for equalizing will work just as well.

The real battle we all have to fight is motors. How to keep them from overheating. I know Mike ran into this problem and he was not the only one. I heard that it was pretty common. I can suggest put at least 2 fans on your car. Team Tamale makes a trick fan mount that allows up to three fans and its about 15 bucks. The other thing is on those hot days (IE MD Charity race this past July) you sacrifice a little over all power for consistant 5 minute run. I recently read a post by Eddie0...someone asked him how do you know if your motor is too hot. He said as long as your lap times don't drop more than 3 tenths per lap your fine. I have personally had motors come off over 200 degrees and they showed no fade. Every motor is different. This is the battle that guys like Bill and Eddie and EA all have to go through. Bill's doing a great job. I'm sure he will continue to push the envelope with new ideas....it's up to you guys as team drivers to really test it and give him the feedback to know whats working.

With that being said, you guys all know me. if you have questions and no ones getting back to you (yes they do get busy sometimes) shoot me a PM.

Bill, I hope to see you this winter at the ORL races. And yes, you are still welcome anytime you need a place to crash for the races....LOL

If that doesn't work, then I'm gonna try charging at 4-5 amps to reduce voltage and thus reduce fade at the end of the race. Hopefully that tactic will net higher speeds at the end and a stronger finish.

I have been super busy racing the 1:1 car, but with the season winding to a close, I will have a lot more time for RC. I plan to get back into off road this winter.
What's the hot setup for stock 2wd? Thanks!

Dan

Bill had asked me about the cells going bad or venting even with a brand new pack. What I and many others have found is that we are now matching at 35amps to "weed" (yes I said weed) out the bad cells faster. In doing so you put more load and more heat into the cell. This causes a bad cell to go bad faster and a good cell to also go bad faster. It is not anyones fault, be it the end user or the matcher. IB cells don't like heat. So there may be some cases where a brand new pack just assembled has a cell go bad within the first or second charge. If this happens just contact the matcher and they should replace the cell at no cost.

I personally know that all the matchers and manufactures are working to solve this problem. How? I am not sure. Possibly matching them with a pulse discharge or some kind of heat sink.

Things are changing rapidly in the RC industry right now. So whats good today may be bad tomorrow. Just stick with what works and dont try the new "trick of the week" right away.

Reedy KR 7X2 5 min. Finishing just be for the battery dumps. May dump on the last lap. All I have is the Teken Bat DR. So, No good.
After running discharge .90 cut off recharge and store 500 to 1000ah
If I use the Tekin Dr. for equalizing till i get Muchmore tray is it better then nothing?
Next. You say If you get a bad cell send it back for replacement. Disassemble
the pack?

I'll let every know how I do on Sunday. I not sure how the standing are as of now. I believe I'm tied for first after 3 races of 6 race series.
