Ladon, the video, as I stated was for the OP because he opened another topic asking if optipower batteries were any good.
. He is using 6s 5000 but he could be flying a 700 in a 12S configuration, so what Dr.Ben stated is correct.
I'LL SAY IT AGAIN, IT'S THE SAME THING!! 5000mah is 5000mah no matter how many f****** cells you have in series!

You should all buy some of these! http://www.maxamps.com/lipo-6500-3s...re-battery-pack

These would actually come down with icicles on and would last forever! Haha

No wait! Buy these new 200C lipos from me!

Sure Richard and he also asked about 30c and 50c. that's ok I enjoyed your video it was a good one. Oh and also about your 150c batteries that looks like a cheap a$$d website I wouldn't order crap from them. They ain't proved nothing yet so yes to me that is garbage

How about 90C?! http://www.hobbyking.com/mobile/vie...idproduct=51837

Why aren't we running car lipos in our helis? I'll tell you why, car guys tend to be much shorter on brain cells than us heli guys and will simply fall for the bs!

But Richard you posted the video. That guy said the opti power makes 50c on his test or they wouldn't put the sticker on it. He shows his test equipment. I am not talking about other battery claims here. Just going but what the independent tester put on there that you posted saying here is the test. Pound it however you want. Go ahead and throw in the off beat batteries most have never heard of if you want. Bottom line is he is proving the opti power batteries are doing it. I am sure if we sent him a message he will do a 50c battery for us because you want to see it. Don't know why he wouldn't he has nothing to hide.

As far as hobby living goes on a 90c battery I believe it about as much as I believe a turnigy battery is good. NOT!

I think you need to watch the video again, he is testing a 30C pack! Optipower didn't have their 50C (or so they claim) packs at the time! There is no 50C test video and there never will be because they don't exist!

I know he tested a 30c pack. If you could read I said that earlier. He showed a 50c pack and he said that opti power won't put the sticker on unless they make the c rating. So that means that the batteries must have made it. Sorry buddy you screwed up and posted the video. That is what that guy said right out of his mouth. You have no proof they don't other than what you say. Give it up dude. I am not saying they make it either but your video says different

Start with measuring the peak current draw of the aircraft you are flying... 5000mahr x 30c = 150amp max draw, 5000mahr x 50c is 250amp max draw. The closer you are to the head room on any application, the more potential damage to the battery.

If you are drawing 60amp on the 30c battery, does it make sense to pay extra for the 50c battery? I don't think so.

Do I believe C ratings? Not really.

I have no dog in this fight but I too would like to know where in the video there is ANY mention of a 50C pack , let alone him showing one

I would think if they even had one (that passed the "test" ) they would certainly want to showcase it !!!

Been there, done that and old enough to know better.....

50C batteries simply don't exist, is the point iv'e been trying to make.

Ok I will admit I thought he said that 5000 pack was 50c. I missed that. Yes he tested a 30c pack I didn't say that didn't happen. But at 45 seconds left in his video he states that it is his job to make sure opti power packs make the c rating. So since opti power makes a 50c battery and his job is to see it makes it then the conclusion is that he had to have tested it since he said he tests the batteries for them that it must have made it.

I have a friend that argued this same point. Same ratings as you said. Finally he bought a set of pulse 45c batteries and put in his speed Heli. Now on a speed it don't just peak and go back down you hold the speed run for a period of time. Sure not as long as a solid discharge but he called me back and said this. Wow I got a 45c discharge out of my batteries and I would have never believed it. Actually I think when it penciled it was like 42c

Now I just copied this off of battery university's website about the ir

Basically it is saying that the IR actually goes down as it is discharged which means more power and it also goes up a little charging. It also says the best performance is gained after the battery has rested prolly to stabilize things I suppose. Now after it has rested do any of you have a way of measuring the true IR during discharge? Prolly not without special equipment like the guy in the video.

Internal resistance as a function of state-of-charge

The internal resistance varies with the state-of-charge of the battery. The largest changes are noticeable on nickel-based batteries. In Figure 5, we observe the internal resistance of nickel-metal-hydride when empty, during charge, at full charge and after a 4-hour rest period.
The resistance levels are highest at low state-of-charge and immediately after charging. Contrary to popular belief, the best battery performance is not achieved immediately after a full charge but following a rest period of a few hours. During discharge, the internal battery resistance decreases, reaches the lowest point at half charge and starts creeping up again (dotted line).

To really be honest unless we have that equipment none of us knows for sure. He has it I will take his word for it that he tested it and it does it before ppl speculating

Our experience in heavy lifting with octocopters would disagree with your statement. We found the best battery performance with a bit of heat in the battery. We would put a small load on the copter, then back to the charger, then the best performance on the next lift. We experienced this a couple of times. This is just what we found in reaching our maximums.

Battery University didn't say anything about having a little heat in it. They just said the performance of the pack will be better after resting. Obviously you could warm the pack a little. You car runs better with a little heat in it too

Also it was not "MY" statement that was copied from them. But yeah what do they know.

If the heli's demands are below what a 30C pack will deliver easily, you will see no benefit. If the heli's demands are at the limit or higher than what the 30C can easily deliver, you will see a marked benefit.
Bottom line, if had the choice of the two, go with the 50C and never worry. They will last longer because they will not be stressed as hard...Ron

Jeees...I was just reporting what we found through testing REAL WORLD.

Since I don't have PHD after my name, I can't possibly know anything.
