new Lipo tech available. Sounds incredible!

[DebianDog]

Cool please start a new thread with the results! :smokin:

You know how people say that when you buy a cheap lipo that you get what you pay for, well in this case they are WRONG!!! You get allot more. This lipo is amazing to say the least, the very first flight we put on this lipo we got 7 minutes and 50 second flight and ran it until the heli fell out of the sky draining it down to 10 volts. The temp was 87 deg F no puffing. So I put it on the charger and charged it up @ 1C with the balancer, an hour and 2100 Mah later (out of 2200) we had a JR factory pilot give it a whirl. Now keep in mind that we were indoors so couldn't get into the really hard 3D flying but still wasn't easy on it, we got a 9 minute flight! battery was 86 deg F and the end voltage was 9.4 volts people that witnessed this were flabbergasted and couldn't believe that we would fly it until the heli just didn't have enough power to fly anymore. I have video of both of these flights, my original eagle tree FDR died on me I ordered a new one on Tuesday night and it didn't show up yet, but as soon as my new one gets here I will have allot more detailed info. I am very amazed with this pack along with all the guys I fly with... Stay Tuned

Can't wait to hear more!!!

here are the pics I have been promising...

Lurking...I asked about these packs on RCG...looking forward to more data.

Video of 2nd flight piloted by Ron Osinski a Team JR factory pilot.

The timer dosent go along with the times that are being yelled out in the vid because I had to delete a couple of scenes do to some bad language in the backround

Must have been Finless in the back ground :lol: That is one heck of a battery, and it just didnt drop dead either.

How did the recharge go on it ??

I think the other Battery companys are in for a shock on these, if the 6S preforms as well, I know what my next purchase will be.

[Air_Alpheus]

No Finless wasnt there. Here are before and after pics of my charger screen charging the pack after the 2nd flight...

I think the other Battery companys are in for a shock on these, if the 6S preforms as well, I know what my next purchase will be.

After flying my 2nd flight with the new Flightpower 25C 5000mah pack on my 600 yesterday I seriously doubt it. It delivered it HARD and when I landed... It was almost cold :lol:

They are priced the same right now as other 4S packs so unless the 6S pack is going to be in the $200 range I doubt Flightpower or Thunderpower is "too" worried.

Do you trust them enough to continually over-discharge them as they claim?

# Low-voltage safe; no cut-off voltage limit; no more need to time your flight
# Withstand over-discharging
# No deformation after over-discharge

Where is the flight data?

Also if you are using the 1010C to calculate how many mah goes back in I would guess you about 5% to 10% off. Why do I say this? If I take the 2 4350 5S packs off my helicopter (Ion on 10S) and put one on the 1010C with a 210 balancer and the other on the 1010C with a Flightpower V-Balancer the one on the V-Balancer will take 300-400 less mah back into the pack due to it efficiency. If I put both packs on the same balancer, they take almost exactly the same amount back in.

[Racer38]

Well they arent even available yet, and I'm not even in the market right now, so maybe by the time I leave this god forsaken country and get home we will have some good data to judge this by. I am curious as to what cell's they are using.

My 4900 does great as well as my TP 5000, two packs is about all I have time to fly, when I do get time so its no big deal.

I guess time will tell on the over discharge issue, I am sure they tested them for a while so I guess we will see what the end users find !

If end user results show they do infact hold up to thier claims, my choice will be made, even if the cost the same as the others, so long as the power is the same.

[DebianDog]

>my choice will be made

If it is they same price... why?

Not for me - unless they have a 50% off on new packs if you crash policy too?

[Air_Alpheus]

The flight data will be coming soon. Also, I am not working for this company. I am doing an assessment on this battery to verify their claims. Every one always says that you have to stick with the name brands in this hobby when it comes to lipos, due to warrant issues, misleading information about the C rating and just plain crap lipos, like some of the ones found on eBay. You know as well as I do that some of those cheapo lipos out their get hot as hell after just normal flights I see it all the time , some noob will come out to the feild with some brand of lipo that no one has ever heard of and say "I only paid 30 bucks for my lipo" They will put it in the heli and in 2 or 3 minutes later they land there heli pull off the canopy and say "why is my lipo getting fat?" And we all say the same thing, YOU GET WHAT YOU PAY FOR!!! Here comes a company that says don't worry about over discharging or deforming this pack and its cheaper. I myself have never heard of any lipo company making that claim, so I am as skeptical as everyone else. I wrote the company and they sent me a pack to try to verify their claims and that is what I'm doing. I'm not trying to compare to anyone else I'm just beating up a battery to see if their statements are true. If you want me to perform any other tests on this pack let me know...

[Jermo]

run it through 100 cycles taking it down to 80% each time, then re-do your tests.

[Air_Alpheus]

I am planning on running it down till the heli wont fly anymore on every flight, but I am going to discharge it to 0 volts a few times also.

[Racer38]

>my choice will be made

If it is they same price... why?



Cause I'm a hard head, they are suppose to be cheaper which remains to be seen on the 6S prices.

But if you can just fly it till it quits with no worries and it still lasts, thats the point I like about it.

[EricW]

If the no worry factor proves to last a battery's life.
And the lifetime is comparable to other "same priced" packs, than this is a very big plus imo.
For me buying a lipo is not the same as buying a pack of cigarettes.
Both too expensive btw. :)
As a beginning RC heli pilot it would mean one factor less to worry about when I'm struggling to control the heli around the flying field.
Hope they will be available in Europe?
Thanks Air_Alpheus for taking the time to test it and showing us your opinion.

[xStatiCa]

I was looking at the 100 cycle test on their website and noticed that the majority of the lost mah (about 6.6% was lost during the first 50 cycles but after that it only lost 3.3% for the next 50 cycles. I wonder how far that will continue... If it does then it potentially could be at 83.3% after 200 cycles. It would have been nice if the company kept going with the tests all the way until the battery only has 80% of it's mah usable.

Not that we will never know the info below because only the manufacturer could do the incremental size tests but I also wonder what the graphs would look like if it were a 15, 25, etc amp draw and then bump the pack size down to 2100mah and then up to 2300 mah and do the same tests. WIth that information people could make sure they get a battery that will best match the target application. If you knew that going to 2200mah vs 2100mah would increase battery life by 10% I know I would go that route even if it were just slightly heavier. There is a limit though that the heli would be too sluggish but maybe even 2300 would be acceptable to some. It would be great if the battery manufacturers would do all these extensive tests and post the data. Then again maybe the manufacturers have already done these tests and come to the conclusion that the difference is not big enough to even worry about publishing the data.

[Finless]

OK based on me hearing MANY Trex450's and that being an 11T pinion.... I hear bogging that I do not hear using Flightpower 2170's.... Might be better than the TP packs that I dont doubt but based on hearing the head the FP2170's kick thier but.... again based on the video and sound....

I would love to:
1) Hear a 13T setup run hard and put away wet ;)
2) Eagle tree data

Bob

[Air_Alpheus]

Eagle Tree data coming soon, my new one just arrived today and we will be doing outdoor tests, 13 tooth as well. Remember that those 100 discharges @ 20 amps they were draining them down to 0 volts every time, you will never drain your pack that low on your normal day to day flying...

[Air_Alpheus]

3rd flight at the end after it didnt have enough power to fly anymore I kept reseting the esc and spooling it up until it would go anymore...

[Air_Alpheus]

I discharged the pack as far as I can get it. I put my charger on discharge Nicad setting @2 amps and let it go.There is still no puffing.

Rechecked the pack after letting it sit for 10 minutes.

http://i178.photobucket.com/albums/w241/Air_Alpheus/lipopics2003.jpg

Getting it to charge back up took a couple of tricks. I had to put it on Nicad trickle charge at first to get the voltage up to 8.4 volts then I put it on regular lipo charge with the balancer. Its charging now.

[DebianDog]

>Getting it to charge back up took a couple of tricks.

:lol:

Thanks for the effort :hug:

[Air_Alpheus]

Battery is charged up and all is well, more info to come...

[marcelino]

For the german speaking freaks:

http://www.slowflyer.ch/index2.php

They are well known for good lipo tests.
As mentioned on their newsletter they are testing the new Kokam H5 4000 cells.

The cells reached 350 cycles, charged @ 2C/ Discharged 100%/ without balancer! and they are still fine!

Looks like slowflyer.ch will publish the whole test results as soon as Kokam gives their OK...


Possibly the same technology or cells as you are referring to?
