So the mislabelled 20C weren't so mislabelled after all ?

I've got a pair of the mislabled 20C's. I also have (3) 30C and (2) 25C Flighmax packs. I'd say the 25C's come down slightly warmer than the 30C's and the misabled units are somewhere in between. My current setup is Align 75A/650L on 14T and running 100% flat curve. Putting back in appx 3600mah after 4:40.

Hell I also bought their 2200 mah 30C Turnigy 3S for my 450 and they toooooo shows a little sign of puffing....

Outhouse...what do you recommend for the 450 then? I read somewhere on here that the "Turnigy" was an in house name brand from hobby city and that Flightmax was the real Zippy-H...are those correct information or was it bogus?

"You get what you paid for" <--- that saying is true 99.99 percent but come on.... not on 5 flights and puff already?

My test battery pack (a 15C mislabeled Turnigy) now has 59 flights on it. I fly it fairly hard on the FBL TRex 600 and Logo 500 Vbar. It started to show minor puff around 20+ flights. It is now pretty "round". I guess it is approaching its end of life. The funny thing is the pack still delivering very good power for 5:0 min on the T-600 and 5:30 min on the Logo 500.

At the cost of $59.99 + shipping, I get roughly $1/flight on the big helis. I am happy :)

I also have a few Zippy H 5000mA packs here. One them get to 95 flights already and still not showing any sign of puffing. I think the Zippy H packs are much better than the Turnigy packs for sure.

As far as 30C rating from Hobbycity packs, I don't believe they rate the packs very well. A friend of mine has a few Flightmax 30C packs, they are puffing after 20-30 flights. One of his Zippy H packs is just now getting 195 flights on it and just started to puff.

great point and it proves what we already know. look there cheap lipos, quality is hit and miss. not every 20C is having issues but for the extra cash i thought it smart to leave a little headroom in my lipo to keep as much heat away from a already stressed 6s system.

another good point your making is that it seems to be common that both brands are swelling and many reports are coming back that allot of the power is still there as to where many lipos start puffing a we bit and you know there at the end of there power cycle with pop.

I'm at 20 packs on my mislabeled Turnigy packs and so far so good. One puffed a tiny bit but that was totally my fault when I took 5000mah from it ooops. But even still, I took it easy on that for a few flights and now it's totally fine again. Love these cheap packs!!!

"seems to be common that both brands are swelling" <---- Well I guess I am screwed all around now...I still have the original Zippy H with at least 50 flights..6-8 minutes flying around leasurely and they come down warm...NO PUFF there...HobbyCity ya'll need to bring back the Real Zippy H !!! or can I get my money back for these balloons ya'll called Lipos...???:mad::thumbdown:

theres people with both that are not puffing, you knew they were cheap going in.

i dont know what there would be to complain about since most people despite any puffing are still getting there money out of them.

all 4 of my turnigys are solid

3s 2200 30c
4s 1800 30c
6s 2650 30c
6s 5000 30c

The ones that I haven't over-discharged are not puffed at all...they're perfect after 20 flights....I'm one very happy customer.

how is your CG with these 5000 30C pack? where do you put your Rx batt to have it balance?

outhouse
09-27-2009, 02:22 PM
RX pac is right under the 5000 with no cg issues

no Rx pack...no CG issues either ;)

BEC is my next move, flight pac is silly

I threw my Align voltage reg and rx pack out the window and now use the Castle Creations BEC PRO and i LOVE IT! its an awesome BEC with full programmability and it doesnt even get to ambient temp haha its awesome

It's not so easy to test a big heli as it is a plane.
Onboard recording amp meters are expensive!

I'm a BEC pro user as well and very happy with it.

:confused:

An EagleTree V3 is only $70. Best piece of equipment I've bought in this hobby. Lets you figure out EXACTLY what is happening with the power system during flight. Add a Brushless Tach for $15 and a temp probe for $10 you can map headspeed and battery pack temps as well. All for less than $100.

Plus it has a pretty decent memory amount. I can get ~45 minutes of logging at a 1 second readings.

Well worth the $95

I just ordered the eagle tree stuff and can't wait to try it

Eagle Tree is great:thumbup:
Im about to buy several 6s pack for my stretch 600 with 1915 motor, as it will use 2x5000 packs, the 30c packs are very tempting, but could somebody do an Eagle Tree test between the 20c at 59$ a pack and the 30C packs?
Would love to see that.

could somebody do an Eagle Tree test between the 20c at 59$ a pack and the 30C packs? What are you hoping to see? As good as the ET is, it doesn't measure the (possibly expanding) waistline of the batteries;) This is a 12s setup? And your motor is rated 1,800W sustain / 3600W burst? Let's do the maths: 1800W/44.4V = 40A. You want to fly 2x 6s5Ah bricks (at 1.5kg)? 40A/5A = 8C - that should be a walk in the park for a 20C pack. Same again for the burst: 3600W/44.4V = 80A; 80A / 5A = 16C. If the label on the 20C pack is anything to go by at all (and it may not be on Turnigy packs, as outhouse tells us), then you will see no difference on an ET chart between that and a 30C pack.

Why do you use a ET? Not for waistline measures, I agree.
I can pic up a calc anytime.
I want facts, real facts.

The 30C 6s 2650 turingy's gave 20% more power on a 6s 500 than the 3000 mah 25C, also the motor was suposed to peak 1600W pr specs, it gave 2600W.
Why? I don't know.

My 2xFlightmax 2200mah 4s 20c are glowing of heat in my 8s 500, the ET showed peaks of 65A, 2200mah at 30c peack would be 66A, so, as the peaks are only for a sec or 2 it was supposed to be ok, average of 30A, right? 20c constant, 30c peaks written on the packs.

With new 2x4s 2200mah 30C Turigys the same setup gives a stunning 81A and just luke warm packs.

Real facts is always best.
Thats why I ask before I buy 10 packs of lipos worth either 590$ or 999$, I don't want to say after the first puff, "but it is all fine on the paper.";)

If I understand correctly, then any motor will draw pretty much any amount of power until the moment it catches fire (because the windings aren't up to the current). So there's no real mystery to your experience: 2600 / 22.2 = 117A; 177A / 3A = 40C - a bit of a stretch perhaps for a 25C pack (also quite a peak for the 30C).

My 2xFlightmax 2200mah 4s 20c are glowing of heat in my 8s 500, the ET showed peaks of 65AI don't know, man. The pack's peak rating is 66A and you're actually peaking 65A - that's cutting it pretty fine, don't you think? When it comes to the labelling, I think 2 seconds constitute one man's burst and another man's sustain. When I look back at the maths I did earlier for the 12s setup, the numbers all came in a lot more comfortable. Sure, you may be able to push the Neu even beyond 3600W, particularly since you will be carrying quite a bit of weight, but if you do this so often as to require a 30C pack, I suspect you not gonna spend much time in the air.

Real facts is always best.Sorry, there I must fail you. Mind, even if I flew your exact setup, I rather suspect that our flying styles would be different. According to outhouse, my 6s setup should be puffing on my 20C Zippys. Yet it is doing no such thing.

Thats why I ask before I buy 10 packs of lipos worth either 590$ or 999$, I don't want to say after the first puff, "but it is all fine on the paper.";)Yeah, but you not gonna do this. Like everybody else, you will buy two, a 20C and a 30C. Then you do your testing on your bird doing your flying. And then you will conclude for yourself where to put the money. And perhaps post the results here?
