Daniel,

The new cells have about four runs on them now and they have gotten faster each time out. They had stupid pull tonight Awesome!

We're finally getting a local track here in Columbus. I will be getting a 12th scale in the next couple of weeks. Keep me in mind on my 4 cells....

Thanks for the support.

Hi, I have been using fukuyama matched cells for almost a year now. The data on my cells are around IR 14, AV 1.175 sec 407, Amp 6 Dis 30, DT 5000 I checked out the latest SMC packs, and they have IR around 2.5, DIS 35. Does high IR affect performance? What does DT stand for?

My cells can be usually charged up to 2800mA with 1 peak at 6A after putting the cells on rayspeed tray. I set the delta peak to 0.03V. If I increase the delta peak to 0.05V, will my cells get more runtime and punch?


All local racers (almost all sponsored) except me are using SMC packs, and they all do deadshortening with their cells as suggested by SMC racing (Check out smc charging tip). I know that Fukuyama warns against dead shortening their cells. But SMC racers can charge their cells to 3700 to 4000mA. I wonder how I can add more punch to my cells.

I am here just to seek advice, not complain or critize. Note that I cannot get help locally because I am the only Fukuyama user.

I think Fukuyama is right with warning against dead shortening of the cells. Itīs too much risk damaging the cells especially if you donīt know how this has to be done correctly.
But we have found here an other way of getting a very similar result. The secret is having an absolutely empty cell before charging. The Rayspeed and Novak trays may be OK for discharging at a higher current draw but the problem is when they are cutting off the battery isnīt really empty.
The Robitronic and the new LRP equalizing trays are working different. Theses are discharging at about 1 amp only and they donīt shut off but limit discharging at about 0.8 V for each of the cells. This means when the cell is near the end voltage the discharging current is lowered until there is no charge in the cell. This needs much more time than using the Rayspeed or Novak unit but means in the end you will have a perfectly equalized battery with no charge but still a voltage left. Also this way you wonīt have any reverse charge cell as it will happen with deadshorting. This way you will have a higher runtime and voltage during your race. Only problem is you need more than one equalizing trays as it needs about 2 - 3 hours after discharging to 5.4V.

The other thing is after one year the batteries wonīt be as good as new ones. Usually during this time a lot of development has been gone with the batteries also the cells will go out of match. This is even with the best matched batteries. But using the equalizing process above this wonīt happen very soon.

The Rayspeed tray has switches on it so you can discharge your pack at a 1 amp rate and a .1 volt per cell cutoff as well. The way I do it is put the pack on it with the 5 amp discharge and the .9 cutoff, when that is done I flip the switches to the 1 amp discharge and the .1 cutoff, when that's done I charge 'em up.

That's exactly what I've done for the past year. It seems to work well especially for the batteries that are almost a year old.
