New Turnigy Nano Tech A-Spec Batteries


So Turnigy has some new batteries out, has anyone looked into these, or even used some?

Have some 6s 5000mah at the post office. Just have to pick them up
These are to be used as a 12 cell combination in my Spark.
We'll see.
I've had no problem with the other Nano Techs

I think it's always too early to ask about performance when first out ... like the Nanotechs previous - are they really that different from these ? - it took a number of cycles and months to show up they were a poor substitute for straight LiPo's.

I know that some swear by them - but a lot of people don't. And I think it relevant that a NEW form of nano's has appeared but straight LiPo's soldier on.

In my book - you don't get anything for free and to think that a form of battery can provide such a wide range power / C rating is in that book ..... Personally a standard LiPo of suitable rating is better. There's also another factor ... the nano's are HEAVY !

Yes Nanos are heavy, so are all batteries.
Nano's in most cases are lighter.
All weights off product configuration table. All 5000mah except 2 bottom ones, 8000's that falcon 5 used.
Here's a good example, falcon5 was running Zippy 8000mah 30C in his T-38, he changed to Turnigy Nano 8000mah 25/50C. He saved 460g or 14.63 oz.
Nanos were lighter!
Not all 5000mah made in same C rating. Close as I could get.

First batch of A Spec will be great, next batch will be made by a different manufacturer and will be different.

Typical HK story.

Buy from the US warehouse or you will be double screwed.

Glad you said most and not all .... I should have qualified my statement because I use Compacts and this is case :

Zippy Compact 2200 3S 35C 181gr
Nanotech 2200 3S 35 - 70C 199gr

Most Nanos are heavier than Compacts ...

I have been having good luck with Haiyin batteries. They have a Las Vegas warehouse. Order Weds. Have them Friday.

Also great customer service. Just send them a picture of your bad battery on a meter and they will ship a replacement to you.

I have had great luck with all the hobby king battery lines, I have Turnigys, Zippys and nanotechs. You can not beat the price and they have performed great. I am a weight nut and the weight difference is very minimal if you are sticking to the same c rating. Keep in mind the chemistry of the battery when making a purchase: That 181 gram Zippy can really only charge up to 2c and the 199 gram Nano can charge at 5c, if charging time dosent matter then buy the Zippy. I have also seen a nice increase in power with the Nanotechs compared to other batteries but thats not always benificial at the cost of weight so thats another thing to consider.

Everyone will have their own opinions when it comes to batteries. I can tell you from first hand expeirence we have tested the Nanotechs at 200 amps and they hang in strong no problem!

I have a whole bunch of puffed nanos, they puffed after being used once at much lower amps than their rating. To me, same as the old Turnigy, just a different cover. A Spec? I assume, just more of the same.

Gens Ace, a different story, so far, so good.

Look up MCSGuys thread...

For the money they are towards the top of the list... they really really put out under a 30 C load (150 amps for his test ) and don't increase heat but 10 - 15 degrees... a good tell tale that they one of the better C ratings

Caveat though...as usual the reason they're not number one is cause A-Specs have that one cell that'll not want to put out lets say one out of ... 30 (my experience) cells that says screw it.

But... but they're sold in the US now so putting them in a 5usd flat rate box and shipping back to the US ware house is WAAAAY easier than before.

I've got the "boat" A-spec backs here...

http://www.hobbyking.com/hobbyking/s...arehouse_.html

and here

http://www.hobbyking.com/hobbyking/s...arehouse_.html

They're more expensive and you have to solder you own cell count

but

but

The 4500s are LIGHTER than 3300s at same cell count !!

The 6600s are LIGHTER than 5000s at same cell count !!

Yeap, fly 30% more time without increasing your weight 30% ... and and have a true 30c to 3.2volts a cell out put....

I've kept mine < 20c pulls but I RARELY get to 3.2 under load because I'm paranoid and fell I've been flying forever

I was doing around 130ish on a 6s pack and kept the plane in the air 5 and half minutes and came down with 2 more minutes to go...
