It's also been said that balancing a lipo can actually cause some problems. I think that sometimes these boards get into discussions over how many angels can dance on the head of a pin...when in reality, it really doesn't matter.
If you buy a decent battery, it will last a long time. Balance it occasionally if you want...or don't. The marginal benefit of balancing every time will probably take a while to outweigh the cost of balancing when you take ALL of the costs into account. No battery will last forever, no matter what you do...just don't over charge or over discharge it and you're 95% of the way there.

There ya have it sports fans and LiPo neophytes... read it, read it again, learn it and get used to it. The R/C car racing world changed for good on January 16th, 2008. These aren't your father's batteries anymore.

I hope not. I don't want to see any of the crap that was the world of Nimh carrying over to Lipo.
With the cells being ROAR legal now, I know we probably will see special labels and bogus claims like "matched" and/or "pro" or something like that, but hopefully, just for a little while, people will just be happy with all the benefits of Lipo and not be so interested in making it the headache that Nimh was.

This has been hashed out with other brands releasing new packs making claims on performance, enduance and quality, it shouldn't be any different for anyone else. Make the claim, you'd better back it up somehow.

TrakPower's are 25C now, I called them (a month or so ago) and got the whole lecture on what they do bla bla, and after all the testing they did, they were putting out 25C....
i see u wrote now does this mean if a LHS has old ones sitting around they are 20c

Tower shows these as "in stock" now.
Anyone have a chance to see how they stack up against the others that are out yet?

A huge thumbs down to Checkpoint on this one. They are using Enerlands bottom of the line 16 C cells. They could have atleast used the middle of the road stuff for this kind of money.
Wasted another $120 just to find out what they could tell us up front but won't.

deception and omission in r/c
HOLD ON!!!! Are you saying that a company with checkpoint's outstanding reputation of slapping their label on someone elses products and charging a premium price didn't disclose the c rating on their awesome cells because they knew the c rating was low?????
How can that be. Welcome to the world of r/c, where ethics, profit, and disclosure live on different planets.
At least orion lipo packs are the real deal.

That is the exact fear of most us regarding the hard cases.....what are they putting in these packs? Thats a really shady way to do business...I have 2 CP chargers. I am going to sell them now b/c of this.
I am still questioning Trackpower's C rating. They still advertise their 4900 as 20C. I just had one ordered in, and on the battery it still says 100 amp constant, which is slightly higher than 20C (20 * 4900= 98amps). So which is it?
I am just confused now more than ever...CP is selling a battery engineered by Trackpower that is overrated, while Tracpower is selling a battery that is under-rated???? What is going on????

I am well aware of that. I guess I should have elaborated for you. In previous posts on this thread somebody said the TP was 25C. Now 4900 at 25C would be 122.5 constant amps. That is a HUGE increase over their advertised 100amp rating. So I was asking which is it, meaning the advertised 20C rating, or the supposed 25C rating posted on here.

Wait, I thought we weren't allowed to know what cells companies are using because it's none of our damn business? I'm shocked, SHOCKED to hear they'd slide a cheap ass cell inside a case and charge a premium for it. Man, I'm surprised nobody thought of that before. Oh wait...
