When will C rating stop going up?
I'm tired of buying new lipos every two months because of the C ratings going up every month or so. Is there some maximum C rating rule anywhere? When will it end?

you dont have to buy new lipos every month. at some point, the higher c rating will not help you anyways. if u have a 30C 3800, which means a 114 amps, and u are running a brushless system that peaks at 80 amps, its probably not going to make a difference whether your batteries can produce 114 or 125 so ur 30, 40, 50 c whatever wont make a difference, because they will never be called upon to produce that.
Technology will always get better, but if what you are using works, then why change it? Buying lipos every month or every other month eventually is your own fault for trying to keep up with the joneses instead of just working with what you got, you dont have to buy anything lol.

I am still running the same 3200's I started with and winning on a consistent basis. Other then buying more because I am running more classes I havent replaced any. Still running strong.

I'm pretty new to racing so I really don't understand the C rating. So why are new lipo's being released with higher C ratings? Is a higher C rating better for lower turn motors?

they need as many fools as possible to keep selling product. the way of the world. they cant sell ya on voltages, amp discharge, IR, etc. so they need somethin beyond mah (which are all far plenty for 5min racing anyway). thats their game.

The truth is, if you just started out, and you're new enough that you're asking these questions, the LiPo you pick probably isn't going to matter to your race results. Even experienced racers don't really NEED the latest batteries, most just buy them because they think they need them. Use the batteries you've got, and use them as often as you possibly can, 'cause if you're new, practice is what matters.

Well said lipo C ratings are mind games to some extent.

correct. you determine maximum possible amp draw capacity of the battery by taking the capacity (3.8 Amps) times the C rate (30)
3.8x30=114.
So C rating only becomes important if you are running a setup that can draw more then the battery can supply. if you are running a 13.5/17.5 setup. this would range into the highly unlikely to impossible category.

My driving does need some work. I'm just not up to speed with lipos yet.
So what about run time. Does more mah mean more runtime just like with the sub c cells?

IF all things are constant except batteries. (Car, Driver, Motor, Heat length, gearing, track etc etc etc)
Lets set up a hypothetical with those constants and a 3200 mah battery and a 4800mah battery.
The higher the mah of the battery... the more voltage it will have left when the heat is over. Meaning that both lipo's are going to start with the same relative punch/top speed (as long as your c rating is such that the battery is not the limiting factor) as they are both starting out with 8.4 volts. However, as the heat moves forward the 4800 will have more capacity left and should have more voltage at the 5 minute mark. So... for racing stock having more mah is a good thing for this reason.
Make any sense?
