Turnigy nano-tech batteries
 

Hey can anybody give me some real feed back on the preformance of this battery vs other.I mean what makes this nano stuff so good is maxxamps better than these for hardcore,insane bassshhhiing?I am a battery rookie guys.

Loaded question
 

Man now that is a loaded question. Try doing a search on here for MAXAMPS and see what you find. There are not too many fans in here for sure. As for a comparison I would have to say that anything at all would be better than a battery with a flame sticker on the side. Nanotechs are just fine and well worth what they cost. You can buy two or three nanotechs for the price of one Maxamp pack, and get twice the usage from them.

I had two 2S 6000 mah Nanotechs that puffed a bit when used in a E-Revo Brushless. I had one 6S 3000 mah Nanotech puff in a T-Rex 500 Helicopter. I had 4 tiny 1S 300 mah Nanotech lipos fail miserably in a micro heli. I am not a fan of Nanotech lipos because of all these failures on the ones I had, no matter how cheap they are. Ever since I started flying RC helis, I've been looking around at what the pro flyers use. 3D heli flyers abuse lipos more than in any other kind of RC, on par with some extremely high performance RC boats. And for those 3D heli pros there seems to be only two kinds of lipos, Thunder Power for the richer dudes and Gens Ace for the less fortunate dudes. I'm a less fortunate dude so I'll be going with Gens Ace when I get new lipos.

It's Gens Ace for me, too. I've been pleased with a number of their packs in various sizes. I was able to data log a set in my large scale truck a while back and saw a nice, low ripple voltage:

thanks guys for the good leads.Whats gens ace highest c rating battery and i also had some nano techs puff as well but,even with a slight puff they still worked the same.3D heli guys is exactly whom i need to speak with to find out what batts. can take abuse have you abused gens ace batteries?

GensAce will be releasing "65"C lipo's soon and I'll get me a pack to see if it's really better than their older 40C stuff which I'm a fan off. GensAce 40C packs have very low resistance can be charged at high C rates. Check the review section.

I had two 3s 25C 6000mah nanotechs. They puffed about 2mm but what didn't like the most that they started to disbalance below 3.4 V/cell. I still have one pack and it keeps showing stability. The other one has two dead cells (it had a light crash but it wasn't a sudden death, it happened in a bout a 3 months).

how soon is soon for the 65c gens ace SNELLEMIN?how did the 40c handle,were they true 40c?

I use the Nanotech Hard Case Lipos (6000mah 65-130C) but I'm pulling 150 amps at most so I guess I'm not stressing them.

I have bought one Gens Ace Lipo, a 5000mah 40C 4s for my SC8e which I had been running a Turnigy 4500mah 30C. Max amps that thing has ever pulled is just shy of 100, but the Gens Ace pack blew up like a balloon after one run (split the case)

...so from my experience, the Gens Ace packs suck!

what application did you have the gens ace battery in?

:rules:

I`ve got 8 of the 5s 5000mah Nanotech`s.. 4 25C, and 4 45-90C..

Used in my RC8T cc1520 geared for 80km/h, in a 60" airplane as 5s pulling 70A max, and a 78" airplane in series as 10s 5000mah pulling 90amps constant at max throttle..

Not one of the 8 batteries has puffed yet at least, and i`m very happy with them so far..

But i guess Heli`s pull alot more amps than this, since they demand that much battery power?

So here we go, just like any other lipo thread anywhere else on the web, someone asks what's good and ends up more confused then before they asked the question. :lol:

Hey guys how long do thunder power batteries last will they last a year of abuse from drag racing a heavy ol' 1/8 scale buggy?Are they true to there c rating?

Dragracing is all about burst power. So high amperage(Torque) capability is what you desire. Second keeping the voltage(horsepower) as high as possible under that burst power.

I haven't had good experience with Nano-techs, which is weird, since the normal Turnigy packs have served me well.

Got three 4s 25-50c packs, all three are light puffed and can't hold voltage. To start with I would get 14 minutes in my 8ight, but last race they all tripped the LVC after 2-4 minutes. I ended up borrowing a pack, a Turnigy 4s 25C 4000, and that had no problem giving me the 10 minutes I needed.

So know I'm kinda on the fence on what to go for, for next year.

did some stupid,crazy passes with the nanotech batteries.Both the 6s 65c puffed slightly i was doing 112mph passes back to back though i think the regular turnigy have 8 gauge wire mabe better current flow

What was the battery temp when you were done?

didn't temp the batts but, i felt them they were warm for shure motor was 172 though.

Hi.I've had no problems with 'em. One of mine got dragged round the car park for a few hundred yards,it was dark & the battery door popped open . I wrapped the damaged bit in insulation tape,charged it & it's fine :)

How old where they?

no more than a month old ill soon be trying thunder power 65c but my buddy says i wont notice any difference in nano techs than thunder power but my electronics will notice the diffrence i also spoke to caste and they say that hyperion is the best hands down.

I use(and sell) Hyperion packs myself - the best Lipo available IMO.

The nanos have low ir and great punch, but the overall "build" quality cant compare to the hyperion.

Here's a couple of interesting vids from HobbyKing.

A comment I wrote on Helifreak about it.
''Very interesting indeed, but I don't know how to feel about it. Is this a true test? Unbiased and totally legit? Did they really take one battery of each brand at random or were the batteries tested prior to the movie to make sure Nanos look good? They say the TP puffed, but it's hard to see if it's true from the vid. I am still not sure what to think about this. Is TP really not all that good? I never had a TP, I can't afford them. But I used several Nanos and they all failed miserably.
This darn lipo market is messed up man! I don't know what to think, what's good or bad and what to buy anymore.''

Yeah! I'm quoting myself here. How lame is that. One thing that someone else made me realize is the Nanos perform really well at first but they crap out after just a few runs and that is exactly what happen with all the Nanos I ran on different kinds of RCs.

I saw the email for those videos this morning, but didn't watch them. Any testing where the manufacturer/reseller tests their product against another brand always has the chance to be biased. Besides, you're not the only one I've heard where the nanos have puffed after a bit of time.

I have 8 nanotechs 5000mah and 2 6000mah batterys, and none of those have puffeded.
Atleast its better to buy turnigy at an decent price than other chinese cells with an "brand" name sticker on them.
Hyperion use korean made cells.

One thing that is important no matter what brand you use is to never discharge the cells below 3v, if you do that it will quickly get damaged and puffed. I recommend to use a device like junsi cell-log, cheap insurance. Some charger have inaccurate balance circuit=quickly damaged lipo

Actually, there have been reports of puffed packs from just sitting at storage levels. But yes, making sure they are not discharged below ~3.2v and stored around half charge does decrease the chance of problems.

I tired the Nano 6000mAh 25C packs and they gave me no performance difference when compared to my Turnigy 5800mAh 25C packs. Absolutely no difference at all. I have sold the truck with the batts so I couldn't really speak about their long term performance but it seems to be a common theme about them that most users don't get much use out of them. For me the normal Turnigy 5K 40C packs have been excellent and see no reason for changing to anything else. They still destroy my diffs, twist my dog bones/CVD's, break the drive cups.............:lol:

I wouldn't expect you to see any real difference between what is essentially two IDENTICAL battery packs of different brand/model; you should have tried the 35c or 65c packs vs your existing 25c packs.

I went with them because of capacity and they aren't really identical packs. They have same C rating but they market them as having lower IR which you would think should improve performance somewhat. Anyway that was in my old Revo. The Savages are way to heavy and demanding for 25C batts. I run normal Turnigy 5K 40C packs and they are excellent for my needs.

the best lipos I used ........ real life cycle of +400 (I tested) and much more hard than the "normal" zippy and turnigy .......... and 10c charge is great :lol:


for me the unic problem is are very long and isnt easy fit in a lot of rcs

pd: I have 12 packs of 3300, 4000, 5000, and 6000 mah .....

I have 2 puffed nano-tech 45-90C 5000mAh 5S. They were good batts for the first 10 discharges and then started to puff. I have been using them in a high power rc boat that pulls about 10C of current from each pack. I run them 5S2P. Now I have two brand new gens ace 30C 5S 5300mAh and I'm running in them for the first 4 or 5 discharges.

Will be waiting for Gens ace review, Bigbore!!! Those batteries are what I'm going to use.

Check out the review section for the GensAce reviews.

anyone tested the new a-spec nanotech lipos? ...... 20-25% lighter than the "normal" nanotech .... and more cycles of charge

I bought 3 a-spec 6600 65c ...... soon notices ;)

You are so full of it.

I watched that Hobbyking nanotech vs. TP pack video a few months ago and can tell you that it was completely rigged. They pre discharged that ThunderPower pack to ~30% SOC and plugging the pack in and not seeing the rest voltage just reinforces that theory. Secondly, you notice how they don't even film the TP pack when they say it PUFFS? The voltage would not increase if it were fully charged when heating up, but it would if it was less than 50% SOC.

I wouldn't doubt that ANY pack would puff when discharged that deep, but not even showing it...

The video is a joke, and Nanotechs are garbage.

That 6600 a spec nanotech looks interesting. The power to weight ratio they are claiming is incredible. The super short leads are a great idea.
