I would doubt he is done because of that. I would be more willing to be he is done because of you

Ok I am gonna try one last time. I did a little reading and found a guy that is sport flying a 600 trex on 6s. He is averaging approx 86 amps on his flights on 6s at 2000 head speed. Ok now do the maths as it should be easy. 86 / 6 is 14.33. So that would mean each cell is carrying 14.33% of the load because it is 6s

Now Ryan is not sport flying at all with his. He beats his Heli good like a lot of ppl. Also this is a 700. More drag. Bigger blades and letting it rip. 2150 head speed on 12s. His amp draw average is about 125 amps. In fact he uses a 120 esc on some of the 700s plus we are not sport flying. If he was sport flying the draw would be even less. Ok 125 amps divided by 12 now is 10.41. So now each cell is carrying only 10.41 % of the load.

If you were using a 700 for the 6s system and trying to run that same head speed and fly like it was being flown in the second example the numbers would be farther apart. Not closer.

Ron is absolutely correct but you seem to want to twist everything around to something different. I just hope the new ppl flying can figure it out.

Over and out

If you don't understand battery watt hours (Wh) (the definitive measure of battery power), Google it!

For starters a 125A average flight would be over in literally 2 minutes!

I think we probably both understand it (I definitely do), but you and Ron seem not to be able to grasp the fact that the load on the battery cells is the same despite them being almost identical in Wh!

OK let's use your 6s 700. 6s 10Ah or 12s 5Ah have the same Wh!

Now IF you were to run 12s 10Ah in your 700 THEN the load on the packs would be halved. Do you see? Please say yes??!!

Huh? Well that is perfect then. You are saying we are using less power with the 12s setup so that means there is even less load on each cell. So if I can only get 2 min of flight time at 125 amp average then let's figure this. And I am being conservative here too. We get an easy 3 min. So that woul mean a third less amps. So subtract 40 amps from 125. That is 85. Divided by 12 for the number of cells is 7.08 % of the load per cell. Compared to each cell carrying 14% of the load. Keep talking you seem to prove more and more that Ron know what he was talking about. Maybe you should get a clue and compare the whole picture not just a small portion

I think at this point Ron has fathomed it, it's you who is struggling and seriously stop replying till you know what your talking about! You are all over the place with your calculations.

No he just gave up on you. I am just measuring the percent of load on a cell. You are the one that said my amp draw was too high for the 700. If you were smart you would have said I was too low then your statement would be more correct. All I and some of the others can do is hope the new ppl can figure out that all you have done is change the subject and leap over anything that proves you wrong

Take my 450 example. Why is it they get the same flight times with more power and less mah on a 6s 450 than a 3s. Ppl I know doing that are using 1350 6s packs. We have a 3s 2200 pack we get the same flight times as the 6s and they use smaller packs and get more power and use the same head speed. Think instead of arguing just for the sake of arguing. There is a reason for it

Ok Richard pmed me and pointed out I was wrong in a calculation. So I want to clarify when I changed my amp draw from 125 to 85 I was off. See I just rough figured it in my head but thanks to him being the straight up guy he is he corrected me. Here it is

"3 minute flight using 4000mah (80%), that's 1333.33mah per minute, that's 80,000mah per hour or 80Ah. So your averaging 80A not 125!"

So now with the new numbers I can be more correct on the percent of the load each cell is carrying. 80 / 12 is now 6.6% of the load for each cell. Proves Ron even more right. Thanks Richard for this clarification.

Also I have brought up the 450 deal twice. Both times no answer to it. So also on it Ron is again right. If you only use 80% of the capacity for each battery which would be 1760 mah for the 3s pack and 1080 mah for the 6s pack and c rating is included in the capacity used Ron is right again. You could use a lower c rated battery for the 6s.

TKO Ron!!!

That is incomplete information. Use Wh instead of number of cells which on their own is meaningless.

Don't think I haven't noticed your ramblings about 450 setups. I would be here forever correcting you on everything, im trying to keep things simple for you and everyone reading. Once you have grasped it you will understand your findings with your 450's instead of thinking the extra power or flight time your seeing with a 6s 450 is from magic pixies!

Oh I get it now. So these guys that are doing the 6s ain't getting more power? Darn I have been wrong all this time? And the speed guys are using 16s to make the helis go faster? Rats I must be doing this all wrong if I can't get more power out of more cells and voltage. Damn I am such a mess now. Richard save us all and tell me how I have been doing this all wrong. I can go to 6s on our 700s and I would have more batteries charged and can get more flights in. Hurry you might be winning after all

I didn't us the wh

Not ALL wrong, just the part that this topic is about, that you still need the same C rating regardless of what voltage you use UNLESS you increase the pack Wh which is what you have done with your 450!

There are 7 pages of me trying to tell you where you've been wrong! Read the whole topic again before replying.

But the bottom line is that it needs to be in use to make a difference. Sure a 6s 5000 pack individually all packs have the same capacity. Same with a 3s 5000 pack. I understand that part. It is meaningless tho unless you are using it in its application. . It is the load on the system that changes. Sure the batteries max output won't but the system will only use what it is going to. But hopefully the new ppl are at least smart enough to understand that.

I have read the whole thing. The only thing is you keep saying like 5000 mah is 5000 mah. Nobody disputed that.

Do this test put a kv motor that is right on your 700 and set it up for 2100 head speed on 6s. Fly it and see how long the battery lasts. Then put the 12s setup on it and do the same. Betting flight time will not be the same. Plus your system will run hotter. The strain on the 6s pack setup will be greater. That is fact. Otherwise there would be no need for anything bigger

How are you getting 6s 5000 and 12s 3600 as having the same Wh?

Yet again incomplete info! Where's the pack capacity? To keep the same battery weight or Wh the 6s would be 2 6s 5000's in parallel to give 6s 10,000mah or 10Ah in which case the load on the packs and flight time would be the same!

Oh good grief. You just change everything. Now it is 6s x 3600 squared x pie minus the square root of 5000 x 60sec. Poop on It I will just call Sheldon and Lenny
