Turnigy "nano-tech"

[RIPFENCE]

i idi not know they had a 6s 45-90c lipo?? if thats the case then i would rather have the nano

[video200]

they dont for the nano`s i been looking.

Actually they do have although 25-50c . http://www.hobbyking.com/hobbyking/s...dproduct=11941

I am sure the cells in a nano tech are fine, but I am sure the soldering quality is the same as the others, garbage. I just switched to Polyquest 5050mah 35c packs, and will not go back to turnigy/ zippys ever again. The difference is overwhelming. Not only did the packs come back virtually cold with no puffing, the motor and speed controller were night and day cooler than before. And I am talking 5s2p, 1518 neu/castle, hydra 240lv..not a small power setup. Not only that, but I am pretty sure the boat will show on gps and saw traps a faster speed. AMAZING difference, Mike

Nano tech lowers the internal resistance of the cells which allows them to sustain a higher V rating. I believe the layers of the cells are coated with another material that bridges the gaps that the older tech could not cover on a very small scale. I read an article on this approx. 2 years ago and wham...that's when Hyperion and some other mfgs started to market these.

Cells that puff are just poor cells and or not matched well. It is caused by gas build up in the foil.

I could see why the packs would run cooler (less internal resistance), but why would the motor/ESC run cooler?

I'm charging one of my nano-techs right now, and it's amazing. I'm charging it at 3c (it's a 2s 5000mah 25-50c pack). I have the iCharger 206b with P350 power supply and it's great. I can't wait to try charging it at 4c! 20amps damn. That's as far as my charger will go, so I think I'm gonna have to get a new one. Haha! But the good thing is that I can charge all 4 of my LiPos with it at once, or both of the nano-techs at 2c (20amps).

Nano-techs are definitely worth getting!

Hey, When the voltage is stable, and it doesn't drop off or have a hard time being delivered to the esc and motor, they stay cooler as they don't have to work as hard to create the same power. Its really a current flow and efficiency thing.

That, I believe, is why Castle will only allow you one free warrenty replacement when using cheap packs, if you continuously turn in their esc's for a repair and you have been using low grade packs, they will turn you away! They must know something!

The harsher you charge your cells the less life they will have. There is nothing wrong with charging at 1C. Cells tend to vary in V more if charged at a higher rate while making your equipment work harder in trying to keep them balanced.

I've got to agree with Alan on this.
Even if it says you can charge it at 5C, do you really need to? They will certainly last longer & take on a better charge at a lower C charge.
You don't buy a pack on how fast you are able to charge them. You buy it on how it performs while it's discharging.
Admittedly it is good to be able to do a fast charge at the lake sometimes, but I charge all my packs up on Friday afternoon/night & usually recharge 2 or 3 packs up again at the lake during the afternoon. All at 1C.
There are going to be a lot of people buying new chargers & power supplies because most of the ones people have won't be big enough to charge even a 5000mah pack at 5c. That's 25Amps.
But do you really need to?
Cheers.

I have heard that Nano-techs are Hyperion "seconds" with a little les quality control but I don't have any proof.

That's funny!

Nope. No relationship between the turnigys and hyperions. NOT the same factory at all. Hyperions are simply superior to other brands. Period.

What you may be thinking about is what happened to another company a couple years back. The factory was in Korea and made the best cells in the business. Their cells were used by ThunderPower, FlightPower, PolyRC, etc.

The brother-in-law of the owner started carting off the reject cells and making packs that he sold under another name. Needless to say, there was war in the family. Ultimately, the brother in law set up in the states with the same name as the good ones! Pretty much killed the company. TPower and FPower, etc. all dumped them.

The moral is to watch out what you wish for. It may seem cheap today but longevity and performance costs a bit more.

Jim, would you care to share some more info on that matter with me? I have all Polyquest/Poly RC packs, and now you have me nervous! Mike
