Those cell should do fine....

I have several sets of the Fukuyama cells... any voltage you buy will be great... you'll not be dissapointed..

the 1.15's would feel like they're 1.16's..

Ask yourself this question, do I drive good enough to notice .01 volt? Make it .06 volts for the whole pack. If you answer yes, then don't let your batteries hold you up on taking that trophy. If not, then save up your money for a nice charger or a lathe or a better speedo if you already don't have one.

I agree with elnitro... it's how well you drive that will put you on the podium..

Thumbs up Nice post

And thanks for rc-Zombie and elnitro. To be honest, the 1.15s are really high .15s some just at the borderline of .16s so for the investment minded individuals, you can't go wrong them them.

Just merely 6 months ago, the SUPER Cells were only 1.15s with average runtimes. But people have won races with them. For normal club races, then the 1.15s would be more then enough, unless you're at the national level racing against the top guys in the country.

My $.02 cents

I do well with my 1 year old 3000 (1.12) cells in stock, so you should be fine with 1.15 cells. Good luck!

Ditto, I run 1.116v (label info) smc 2400's and have no problems keeping up in stock.(they peaks at 9.5+v's and 2600+mah though) They just get better and better with use.

1.15 cells from Fukuyama are equivelant to 1.17+ cells from other companies advertizing on the board. I bought 1.17+ packs from an advertizer here, and had them rematched at Fukuyama, 3 out of the 30 cells were 1.17's, and low 1.17's at that. Fukuyama's price and service is great, get the 1.15's and you'll be fine.

What kind of amps, voltage cutoff and rest do you guys like with the GP cells?

I have been chargin at 5amps, 5mv on a millenium and not sure about rest. Looking for info for 19turn rubber class.

I charge at 6amps, and repeak at 6.5 right before my heat. .4mv cutoff.

Hi,

The key to it is temperature control. If you can find a decent temp gun or one of those keychain temp probe, then you want to set it at .32~.48mv but during it's last charge stage, if the temp reaches 145~155, cut it off. It'll allow you just a bit more power right AT this stage, the cells should be repeaking with a voltage drop. I've notice that with the newer GP cells, .03 peak detect on my GFX will really be sufficient with nice voltage and the packs are warm but not piping hot. It'll also help the packs last even longer.

Jimmy,

What amperage do you like to charge & repeak at? Do you know how long to wait for recharges if used multiple times in a day?

Thanks for the response.

I normallly charge at between 5~6 amps depending on the surrounding temperature at the track or where I'm charging. I usually repeak at 6amps because it's slightly faster charge time.

As for multiple charges per day, I normally wait like 1 1/2 to 2 hours between charge. During the first run, I would charge the packs. After the run, I just make sure they're somewhere close to .90 cutoff so anything below that is not good. Then after I rest the packs, I'll repeak it at 6 amps with a lower peak detect of say .03 on a GFX or a .3mv.

Hope this helps.
