Default Running RC2400's more than twice a day?

Is it ok to run RC2400s more than twice a day? I have just bought my first RC2400, only charged it once for run and then discharged it via my tamiya discharger, then trayed it in an integy activator x. I would like to know what is the proper method to handle them, if they can be used like twice a day (I had to cycle between 2 3k batteries for my last race!!)

Many thanks. Would also appreciate charge current and delta peak information

Regards,
Alvin

i think that's okay... but make sure the batt is cool enough, before second or third charge..

I run my Sanyo 2400 for twice and sometimes three times a day.

Ensure they cool down, before charging again.

I charge them at 6,5 amps for better punch (I'm running stock class.) I also use a pulse charger for better punch.

I discharge them or drive them till they drop, between charges. Between sessions (racing/training), I discharge them fast, then equalize them. That's all. I've doing this for the 6 month I got the pack and they work real fine.

JUST MAKE SURE THEY COOL OFF!

Aside from that, feel free to do it. I do, without any side effects. And don't worry about people saying it has negative effects, I have been doing it since I got my 2400, and they still run strong and long.


BUT...................................


When I say let them cool down, I mean NORMALLY!!! NOT that "put em' in a plastic bag and stick in an icy cooler" crap! Let them cool down normally and they will be fine for using them multiple times.

Yep, several of my local drivers charge their Ni-Cd's twice a day, letting them cool between charges. They claim it gives them more punch on the second charge, but a few seconds less run time.

That's right, the second run got more punch.

I use my 2000 packs twice a day in practice...But not my 2400s. I let them cool down for about 3 hours at least before running them again, that is after I have left them on the tray for 30 minutes. They seem to work fine still, and I still use one of them for racing.

when letting the batteries cool down between cycles, is it ok to use a cooling fan? without a fan, my batteries usually cool down in an hour. if i use a fan, my packs cool down in about 20-30 minutes. i use my 3000s twice a day and ive read that there should be at least 1 hr rest inbetween cycles. but i dont have enough time to charge in between our race heats. will this affect battery life? or is it fine to use a cooling fan? thanks for any info

Mariv-you should really let the cool down for at least 2 hours. Even though they feel fine on the outside, the cell inside can still be warm, so when you charge again, you are potentially hurting your cells.

I was certainly abusing them yesterday
I tried to get that bit of "Second charge" extra voltage by charging them for 10 minutes, flattening them at 30 amps then charging them again after a short cooldown period.
My cells aren't that flash(Orion "Club spec") in fact they'd be pretty weak compared to whats currently available.

Thanks for the info dudes! Keep 'em coming in! I was considering getting some 2400s for stock racing, and 3000s for mod. But I can't have THAT many batteries
