Give the Turnigy 5000 MAH 30C packs a try. They have more power than the big name brands in my helicopters.

Try the 3S2200 25C Turnigy at http://www.hobbycity.com/hobbycity/s..._25C_Lipo_Pack
Its only $16.95 so you won't lose much. Post the results and we can compare them as I have already tested one.

What i ment with "HC" guys is that pepole that use alot of there batterys, could perhaps have the experience in there product line to point me in the right directlion of a battery worth testing.

Thank you for your recomendation, thats all i wanted, Turnigy 2200 25C next!

Jocke,

Here is a plot of the Turnigy 25C discharged at 20C compared with a Flightpower 30C also discharged at 20C. All other conditions identical.
It looks like the Turnigy is about 3 - 4% up on voltage which should give about 8% more power at the prop. ie a bit over twice the voltage difference.

Jocke · Oct 31, 2009, 07:22 AM

Yes, interesting, i will test the battery, and test it same way as ive done with all other batterys, that also includes cycle life and see where its lost 20% capa.

I have just bought my first Turnigy 25C 2200mAh. I'm not sure how to read the graph, to see if a battery is a good or bad one. Can someone explain how to read the graph ?

That’s what I am seeing in flight. I was using Flightmax and got my first Turnigy a month ago and it does have a little better performance. Since they are less expensive I will be getting Turnigy when my Flightmax packs get used up.

This was obviously bait, and I'll bite...

So...why don't you want to share your results? Is it because sponsors would frown upon sharing of potentially negative information?

If i publish my results, i will have do defend the results from users, vendors and manufactors, i dont feel like getting bashed thru mail, forums becase of my findings, i keep it to myself and share it for the ones that can read it, latest proof of this is the reply from Cribrian. Still diffrent brands of Lipo contact me for my opinion and testing, they trust me, and just becas i would find "bad results" instead of bashing the brand on forums, the results go back to them so they can make there product better.

'Nough said. If you can't publish results and let them speak for themselves, then they aren't worth mentioning.

It's perfectly acceptable to be a confidential, independent tester for various manufacturers.

That said, as soon as tests conducted or results are mentioned in a public forum, followed by revelation of an inability or unwillingness to post unfiltered/unadulterated results, all public confidence in the tests is lost.

So, my $.02 - to maintain credibility, if you mention something based on test results in a public forum be prepared to provide the supporting data, or don't mention it at all.

I bashed you through mail ?

You must have me confused with someone else.

I only asked for the data because you came in here stating you have been testing differen't lipo's. Why say you tested and not put fourth the graphs ?

Jocke · Nov 01, 2009, 04:08 AM

Have i said you bashed me thru mail? no not that i can remeber

I have shosen not to post my results here, by several resons, simple as that.
