OK original it was about the difference between 30 and 50c but this reply started the new debate:
. Some of the best answers will come by what you're flying. A 12S model will push cells less overall than a 6S model. A 30C pack may only get a bit warm on a 12S model flown in a spirited manner, while that same pack might go beyond warm in a 6S model flown very hard.

Sorry but next time try same mA capacity for both and double the motor Kv for the 6S. Kudos for keeping same C rating.

Just keeping things in perspective.

Everything I stated back in my first post of this thread holds true.

https://rc.runryder.com/helicopter/p6608332/

Ohm's law is unarguable.

Yes, you can manipulate R to achieve to any results you want for I and E. Whether they're realistic or not is another story. I knew this long before I told Richard to use eCalc.

You know the old saying, the figures don't lie, but liars figure.

Anyway I just want to check that we are all now in agreement that it doesn't really matter what voltage setup the OP is using as to what c rating to choose?

The higher the voltage, the lower the amperage draws will be so the need for higher discharge capability diminishes. I still say go with the higher C batteries as the overall demand for the battery wil be lower, thus they will last longer.

well you can get away with a lower C rating on 12s because the load/amp draw is less
but on a 6S you'll want the higher C rating because the Load/amp draw has doubled.

I Don't know Richard at this point I would suspect you of "trolling"
(hate that word).

I don't understand the objection...aside the trolling comment.

Sorry, you did not provide an experiment with exactly the same setup, doing exactly the same work, one with 12s and one with 6s....ok, look at it this way:

You are Align fan right? Back in the day when the Align 600 was introduced, it was a 6s Heli. It was known as a battery cooker. They then introduced it as a 12s Heli running higher HS and higher pitch ranges and it does not cook batteries even with more "work". If the amperage draws were the same, wouldn't it cook 12s packs too?

I object that you need lower C rating packs just because your running higher voltage. I've explained why as simply as possible multiple times with proof so if you still don't understand I can't help you further, sorry.

Give me that new trex 600e on 12s and I'll put a flybar on it (like the old trex 600e) and run 2500mah packs (same weight as a single 6s 5000) and I'll kill packs on that heli too!

How many amps you going to pull on 6s? How many amps you going to pull on 12s? What ESC are you going to use on each?

Well in the setups above your going to pull roughly half the amps on the 12s setup.... but here's the thing.... are you listening?.... YOU HAVE HALF THE Ah IN THE PACKS!! Ah is directly tied to C rating, that's what C rating is! C = CAPACITY! CAPACITY IS IN Ah!!

DO YOU GET IT!!!!

Now, are you listening? YOU ONLY NEED HALF because the setup is more efficient SO each of the 12 cells is being strained less...the load is divided by 12 instead of 6!

Ah we are getting there! So what you just said is what I've been saying, you only need half because the load is halved yes? Then the load is the same yes?

12s divided by 12 = 1
6s divided by 6 = 1

Yes?
