RE: zippy lipos are they any good
My only point was you aren't dealing with a dummy. I'm glad others have had good experiences with Zippy batteries. Maybe they've improved since I tried them. Maybe others have gotten lucky and I didn't. All I know is that I tried them and found them adequate when they were new and unusable about about 50 cycles. The aggravation of dealing with them wasn't worth the cost savings, so I stepped up to something better and have been impressed so far with what an extra $10 or so gets you. Other pilots can buy whatever they want to.

ORIGINAL: jester_s1 It is very well established in the publishing world that product reviews are bought and paid for by the manufacturers.

It is widely regarded as the worst made gun that is legal to sell in the U.S, yet the reviewer gave it a glowing recommendation. He was a pen for hire, as are 99% of all product reviews. e.g. it does not follow that stating an 130 IQ means you are automatically correct.

The guys who run the magazines aren't stupid. They know who pays the bills. The reviewer obtained both GenAce and Zippy/Turnigy plus other cells to SCIENTIFICALLY TEST to see if LiPos in general met their "C" rating advertizing claims ( NONE did including the big boys but some were better than others and better values too. ) He obtained the batteries via UK distributors & ebay, etc... he knew nothing about Nitroplanes, Hobby King, etc....

RE: zippy lipos are they any good
I have used several "Zippy" LIPO's for a few years. Mostly I use 2 cell with a voltage regulator for my receiver and servo's. They have performed well, and I would continue to purchase them as needed.

RE: zippy lipos are they any good
I used 4 and 6 cell 5000 ma packs for many years with great success. Zippy and Turningy, but most are Zippy. No complaints.
Gerry PS; I had 2 issues with HK, in one instance they send one battery short, in the other the battery arrived dead. In both cases they solved the problem really fast using the claim form on line. |
RE: zippy lipos are they any good
Ok guys, I've restored this thread. But let me put out a warning here. The bickering with each other had better stop right now. Geoff warned you all about it and you all thought you could just ignore him and continue. I assure you that you WILL NOT ignore me and continue this childish little spat that you have going on here. If I see it continue those doing it can be assured of a some time sitting in corner in a time out. I won't tolerate. So you make the choice as to what you want to do, but please don't doubt that I will take actions here.<div>

RE: zippy lipos are they any good
I have used several different brands, and considering murphy's law, the fact that they are made by humans, and the actions of reckless,inconsiderate electrons, I have had a couple of them puff after only a couple of cycles, others have one cell go doa, requiring me to dissect, and rebuild the remainder into something useable. I won't badmouth one, or praise another. Too many variables. Do any of you break-in your batteries?

How do you break in a battery ?

RE: zippy lipos are they any good
I have not paid hobby store prices for lipos in years. Going there to pay double or triple is not a good use of my hobby dollars.
I have been using NanoTech with excellent results. I buy the highest discharge rate that I can get.. usually 65-130C Yes I don't believe those C ratings, but I do think there is a difference as you step down. My NanoTechs are likely your Zippy batteries... as said before... only a couple of plants in the world produce the things and everyone slaps their label on to claim it for themselves. |
RE: zippy lipos are they any good
My Zippys are great, still strong after plenty flights.
I have a bunch of LiPos and LiFes from HK, I had no problems with them at all. And the c ratings are very optimistic on most batteries. Come to think about it - 30c means your battery is used up in 2 minutes...do you really need that? I don't |
RE: zippy lipos are they any good
their a decent low power set up batt for the price. sometimes you do get a pack though. its a risk you take.

RE: zippy lipos are they any good
I have a number of them and they a powerful and reliable. </p> They perform better in my Stryker F27Q than any other 3S battery I have tried.. </p> </p> I like them very much and great value from Hobbyking. </p> </p> |

RE: zippy lipos are they any good
I also have used HK batteries for a couple years now. I have enough faith in them that I only run one for Rx and Ign. And as in the pic, my planes are far from cheap in money and/or my time.
|
RE: zippy lipos are they any good
Use of a watt meter should tell you the max amps you are pulling from the battery. Do the simple math and you will see how close to the "c" rating it really is. You just might be surprised...
|
RE: zippy lipos are they any good
i have 4 zippy 3s 2200s 25c for my 48" DW Foamie and they work great. Not a problem. I also have some small Nanos and they are great too. Then i have several 4s 4000 25 Gens Ace and they too are great. I've also used valuehobby's 3s 1300 and 3s 1000s and they are starting to get worn. But they are the oldest batts I own with the most cycles.
Bottom line is i've had good luck with all the chinese brand lipos. |
RE: zippy lipos are they any good
"C" ratings are a total crock. At a 10C draw, you'll get about 6 minutes of flight time before you're deadstick. Yes, a high powered plane might run at 15C to even 20C for a few seconds for a hot pass or to pull a vertical line, but that's about it. Most of us run our batteries at 5C-7C average, so it really doesn't matter at all if the manufacturer claims 40C performance. What does matter is internal resistance, which is what made my set of Zippys unusable pretty fast. I don't have the equipment to do a scientific test, but I do have a tachometer that told me I went from 20,500 rpm on my Stryker with newly broken in batteries to 18,100 rpm after about 30 cycles. It made the difference between being able to hand launch easily in nearly any wind conditions to not being able to at all unless there was a strong head wind. Heli head speed suffered similar performance losses using the same batteries. All my Zippys still cycle tested fine for capacity, but the change in the internal resistance made them as good as dead for my applications. I replaced them with Power Wing batteries that were a little over double the price, and got 21k rpm with new batteries and still do about about 50 cycles. Double the price for (so far and counting) double the life and better performance to boot is a good value IMO.

RE: zippy lipos are they any good
Ok, here is the simple math for simple people (like me)
2200mah= 2.2 amp hours (means the battery will last 1 hour at 2.2 amp draw. 25c= charge/discharge rate. 50c=max charge/discharge rate. (in a perfect world, of course) 2.2 x 25 = 55amps Perfect world discharge rate<div> </div><div>Using a wattmeter (anyone serious about the hobby should have one for setup purposes), you can get an amperage readout while running your motor/prop combo, and see if you are getting near to the advertised rates, and if you are near to burning your esc, or motor. I always figure out what the weight of the plane is, how I intend to fly it, what wattage I need to fly that way. Then I figure out what battery I need to attain said wattage. That tells me what esc, and motor I need to operate at those levels, then I prop it to the level I want. So, a 2lb plane, at 150 watts per lb, =300watts. 300watts divided by 11.1, (a 3s battery)= 27.07 amps. lets say, 27.07 amps divided by 20c=1.35 amp hours=1350mah . So, in a perfect world, I would need a 1350 mah, 20c, 3s battery, a 30 amp esc, and a motor that can withstand 300watts/30 amps, and prop it accordingly.</div><div> Just saying that the "c"ratings are a bunch of crap doesn't work in my world. Get a meter and prove it.</div><div> </div> |
RE: zippy lipos are they any good
I do use a meter. My point was that if one actually approaches the C ratings that manufacturers love to brag about, the practical value of the power system is lost. Internal resistance however is a useful number that lets us compare the quality of our batteries.
