You will need a Co driver, because no interruption Rc Racing does not exist... All you need is two packs to have fun when you have Co drivers charging for you..... You guys need to specify alot more when you make your statements....

the heli flyers may have more real world experience with high rate charging.

it is curious that most car packs have a max C charge rating, but the paperwork with the RevTech packages indicate a charge rate not greater than 2C and not less than 1C.

is it possible that bertrandsv87 is a reincarnation of wallyedmonds?

Do you mean 24 amp?

I don't think the electronics in the charger can handle 24V.

From my experience racing a stock slash class it appears batts have a bit more umph when charged at 2C vs 1C. Maybe it also has something to do with them only being used once a week and needing to wake up a bit?

Anyway I always charge at 2C and have gone as high as 4C on my 4 cell packs I run in my boats. In my boats they always come back puffy but then shrink back down after they cool off. Those 90-130 amp discharges are tough on batts. Once they start showing balancing issues I usually cycle them to my 1/8th buggy where they run & charge fine. I have 4 4 cell packs Turngy packs that are 3yrs old & still going strong as well as a number of others. So far no problems.

No a lot of the new chargers can take up to 24Volts. It cuts down on the amperage needed to charge at high rates on higher voltage packs.

You have been spam posting on this forum for near two years now, and you still post a whole heap of nothing.



I often charge my packs at 10amps, but only because that is as high as my current charger goes, should have bought the 20amp version really...

Modern packs are plenty safe to charge at more than 1C, then as long as you have a 'good' charger, it's almost a non issue.

Not that long ago I bought a cheap charger, then watched it sit there and force a pack out of balance in the final stage of charging, one of the balance circuits was that far out of spec it was scary.

Very cool... I learned something here. Any experience with these 24V chargers? I'm in the market for a new one. Recommendations anyone?

Yes and no, it has to do with temperature. I've been playing with lipo's for along time now (12+ years) cellphone packs and the like, for use in rc planes. Back then it was necessary, to pre heat them so they didn't pop.

A good buy, it'll do most anything you need and a lot of things you don't.
