Default Charging bottom line

"50mvp/6cells=8.33mvc. So yes, you're close with that. How hot are your cells getting? If they're less than 120F your not getting everything you can out of them. I'd check the temp at what you're charging at now and if it's too low, just bump it up on the next charge and check it. Do this until you get the cells around the 130F mark and then fine tune from there. Also, make sure you're not charging with the cells on a fan. This can cause the cells to either false peak or mis the peak all together and overcharge them. Don't cool them on a fan either. Always let the cells get naturally warm and naturally cool off."


I have been trying to ask the same question for the last several months, sorry if I sound like a broken record.

From all I can read, to get the max acceleration out of 3300 pack I charge it at 6 amps until it starts to get hot. I pull it off the charger when it is about 120 degrees. I try to time this to happen within 15 mins or less from start of my race.

If I do not mind watching the temp probe and my temp gun (and I do not get distracted) it really doesn't matter what charger I use. As long as it puts out 6 amps all the peak detect and the other options are not really needed, my old nicad charger will do just fine.

As long as you have a linear charge mode and you can turn off the trickle charge, it should work. What charger do you have that you're trying to charge these with?

For an equalizing tray, you can't go wrong with the Rayspeed or the Novak. Both have cutoffs so you don't over discharge the cells. Rayspeed has an adjustable discharge rate of either 5 amps or 1 amp and a fixed cut off at .9v per cell. The Novak has an adjustable cutoff. We reccomend you set it @ .9v. I'm not sure what their discharge rate is but I'm sure it's somewhere in the 1-5 amp range. I personally use the Rayspeed. I like the adjustable discharge rate.

Before your first run of the day, put the cells on the tray and equalize them. Once they're equalized, charge according to the reccomendations on the Fukuyama technical page. When you're done with a run, discharge the pack on a 20-30 amp discharger with a cutoff of 5.4v accross the pack and store the cells after they've cooled. (DO NOT put them on a fan to cool) That's all you need to do. Just make sure you never force cool the pack with a fan. This can shorten the life span of the cells. If you're going to run them a second time in a day, there's no need to re tray the cells. Just make sure they've had 2-3 hours to properly cool. You don't want to charge hot cells.

SpeedtechRC.com has both. http://64.70.208.72/speedtechrc/39.html

John- Thank you sir. When you follow those proceedures yourself twice a week it becomes second nature.
