More than just a fancy name. TURNIGY nano-tech lithium polymer batteries are built with an LiCo nano-technology substrate complex greatly improving power transfer making the oxidation/reduction reaction more efficient, this helps electrons pass more freely from anode to cathode with less internal impedance.In short; less voltage sag and a higher discharge rate than a similar density lithium polymer (non nano-tech) battery.For those that love graphs, it means a straighter, longer curve. For pilots it spells stronger throttle punches and unreal straight-up performance. Excellent news for 3D pilots! Unfortunately with other big brands; numbers, ratings and graphs can be fudged. Rest assured, TURNIGY nano-techs are the real deal, delivering unparalleled performance!Spec.Capacity: 4500mAhVoltage: 4S1P / 4 Cell / 14.8VDischarge: 25C Constant / 50C BurstWeight: 467g (including wire, plug & case)Dimensions: 173x49x29mmBalance Plug: JST-XHDischarge Plug: 4mm bullet-connector *The nano-core technology in lithium ion batteries is the application of nanometer conductive additives. 1) The nanometer conductive additives form ultrastrong electron-conducting networks in the electrodes which can increase electronic conductivity. 2) These additives create a superstrong ability for imbibition in the carrier liquid to supply more ion channels. This improves the ability of ion transmission and ion diffusion. Through improving electronic conductivity and ion transmission, the impedance is reduced and the polarization of high rate discharge decreases greatly.Advantages over traditional Lipo batteries.Power density reaches 7.5 kw/kg.Less Voltage sag during high rate discharge, giving more power under load.Internal impedance can reach as low as 1.2mΩ compared to that of 3mΩ of a standard Lipoly.Greater thermal control, pack usually doesnt exceed 60degCThickness swelling during heavy load doesnt exceed 5%, compared to 15% of a normal Lipoly during heavy load.Higher capacity during heavy discharge. More than 90% at 100% C rate.Fast charge capable, up to 15C on some batteries.Longer Cycle Life, almost double that of standard lipoly technology.

How do i know limit ampere for lipo?
charge at 5c? What does it mean?
5c equal to how many ampere?
I alway charge my lipo at 1.0A till 1.8A for save. I'l
Never charge above 1.8A.
Limit Ampere is identified by the C rating for this battery (4500mAh) a good rate of charge would be 4.5Amps for this type of battery... C is the discharge current the battery is able to give out... its good to have a higher C rating so that your ESCs cannot be limited by battery current draws...
if, when the pack is fully charged, these cells read the voltage you say, it's more than likely time to get a new charger. But first get a new multimeter. Then a new charger. If that doesn't solve the problem, then it's a defective pack, but, I'd be willing to say that if your charger is saying the pack is fully charged when the cells are at 4.03V X2 and 3.75V X2, odds are your charger should be replaced.
50 amps would seem to be the safe answer, deffinately no more than the 70 amps limit of your ESC, the 50C rate would be 225 Amps. so there are at least 3 ways to look at this. the lowest one being the motor draw. looks to me as tho you are very safe as long as you do not exceed the max for the motor.
It's safe to draw uP to112.5 amps.(=4.5x25).
Your setup is fine. Any setup is fine (amperage-wise) as long as bat amp>ESC amp>motor amp. In your case it is 112.5>70>50
You can put it in the cart, and then click to order, then it shows you on the shipping costs!
Properly ordered but not yet but it is only a further step in there!
Hi everybody! Can anybody tell me how these batteries work? I have read some controversal discussions about the nano-tech batteries in general, but maybe somebody has made some experiences with these batteries in special.
this batterie will work very well. but at end of capacity the powercurve will go down very rapidly.
the nanotech batteries have a lott of power so i think this will be the next generation of lipo
These batteries are the best out there in my opinion. Those that say negative things about these batteries had to have gotten a dud. These easily outperform Maxamps and the standard Turnigy Blue lipos.
I bought some of these and flew all last summer on them. There's not a dang thing wrong with them. You can even pump the rated 5C into them and they don't even get warm. They aren't much more expensive than the Rhinos or Turnigies, and only slightly heavier. I see no downsides. Totally worth buying. I'm getting more again this year! :)
these batteries are great,i love them. they have great power and low internal resistance of 1.2 ohms. i use 2 in series in a 70" 3d plane. after a 3d flight the batteries are ambient temperature.
it depends how much mah they both have and i think my standard lipo lasts longer then this.

Great batteries, they fit in the E-Revo battery trays without having to cut the doors (like the 4s 4000mAh 20c's I bought before). Running them in parallel means a very nice 200A continuous rating, no sweat. Runtimes with a Neu/Castle 1717 geared 23/38 go in excess of 40 minutes, no drop in power until the very end. I've also ran these in 8s with two Turnigy T600 880Kv powered 4.5" EDF's, 200 A draw. Batteries got hot, but it handled the current until I hit LVC. Excellent batteries, despite me getting one with a weak cell (~4200mAh vs. 4500mAh in the rest of them). Just because I got one that was less than perfect doesn't mean I'm gonna bash on the entire line and tell people not to buy it. In fact, the opposite is true. If you have an E-Revo and want a long lasting 4s basher setup, these are the batteries for you.
