With the Kontronics, the difference between c ratings is evident after the flight. The lower c rated packs take a beating and the higher c rated packs come out cooler and less abused.Team Sanjel!

That will be the same with any setup, not just Kontronics. When lipo's start reaching close to 150 degrees, they start to show signs of their abuse.

150 degrees and the LiPo is toast (or soon will be) I have read that 130-140 is acceptable. Anything from 140 to 160 will shorten the life of the pack. Anything over 160 will have serious effects on the pack and possibly lead to a puffed pack or even worse, a fire!! My packs NEVER come down more than 130!! No need to kill my batts for a few seconds of extra flight time!!

In my experience 130-140 will shorten a packs life, esp cheaper packs.

My point exactly. A higher c rated pack will produce less heat but not necessarily more power than a slightly less c rated pack when using a Jive controller in mode 11. The power difference will be more noticeable when using other brands of ESC's because they don't have software that maintains head-speed between packs like the Jives.Team Sanjel!

jive would have the same power as the other esc ungoverned.

if i use a 65c on my gov castle esc i wont see any difference in the c rating as well.

higher c rated packs produce more punch ungoverned

That is not true clown. My trex 500 with CC Gov has a significant head-speed increase when I use 45c pack as opposed to 25c pack. If I put the Jive in mode 4, the result would be the same as the CC, but the CC does not have anything equivalent to Mode 11. Mode 11 is setup by using your weakest pack to setup your head-speeds and it remembers the head-speed for all other packs that are more powerful. (this is not exactly how it works, but it is the easiest way to understand).Team Sanjel!

Its all about knowing what your doing, I use 20-30C Turnigy packs.

Pack quality and how its broken in has much more of an influence on power than C rating.

Recently lost a 20-30C pack in a crash and im so glad I didn't pay over the odds for the high C rated big name brands.

C ratings are over rated!

I have never heard of c ratings adding bulk and weight. If you have two of the same brands with different ratings, I would like to see this theory tested. Mah is what is going to add to size and weight. C rating is more of a performance rating.
C ratings are over rated!

Forgotten how to hover!
If you have forgotten how to hover, then you obviously won't see the difference on c ratings. I used to use 20 to 30c batteries and I just tear them up now and the performance sucks. I used 30C and I am quite happy with the performance.

Increased C ratings don't happen by magic.

Take the Voltz series 6S 5100 packs. The 35C packs are 750g. The 65C packs are 865g. Same Capacity, same voltage. Look up the dimensions yourself.

In order to make discharge ratings higher, the cells have to be made more robust, ie, heavier and bulkier.

Oops, they are just a hair heavier than the G6 45C's, but they are a hair lighter than the G4 45C's that they replaced. The G6 45C's are even a little newer than the 65C's. So, the difference is 10g(1/3 oz), which I would not call adding hardly any weight, and size(bulk) wise, they are the same.

The difference in weight between a 20c and a 30c in reality is nothing. The power difference delivered more than makes up for it. I sure don't notice any weight difference.Trex 700E / Trex 500 ESP - Ikon/ HD 500 - Ikon 2/ Goblin 500 Ikon 2

Could either be because of a setup issue (also includes breaking in the packs), poor collective management or you just got some bad packs.

Im also guessing it wasn't a HV setup that was eating your 20C packs?
