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!
* 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 60degC -Thickness 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.
I have two of these batteries, used them last night, I landed my plane just in time as the battery went almost dead and after it landed, it could barely pull any power. The battery was a bit hot also. Where can I go to find out what should be the minumim voltage, and max voltage, and spec's on these batteries. How hot should these batteries get when using them? I use a hobby king charger setup to 2amp charge I believe, what is the max volts it should be before I fly. I am new to these electric planes, got so many questions here, but can't find proper operating instructions of how to use these saftely, besides being told not to drain them for risk of damaging things.
Hi Rambo, these batteries should be 12.6v (4.2v per cell) when charged. And you should never empty them more than 9.8v. This is standard for all 3 cell lipos. You mentioned that they were warm after use, this is normal. I suggest bringing a cooler with sealed ice packs with you when you fly. After each flight place the used battery in the cooler to help bring down the temperature. High temp will reduce the overall life of the battery. When you charge these batteries be sure to use a lipo balance charger. You cannot use a normal charger as the cells can become unbalanced in voltage over many uses. A charger needs to be specifically designed to charge lipos they can be very dangerous and charging them with the wrong equipment can lead to a fire. As for the rate of charge, you can charge any lipo battery at 1c.. This is a 2200 mah pack so 1c would equal 2.2 amps. If it were an 1800mah pack 1c would be 1.8 amps. This nano techs can charge at 5c, so a 2200 mah would be able to charge at 11 amps. And an 1800mah * 9 amps. But charging at high c will also impact the overall life of the pack.
The c rule is 1c = mah rating of battery /1000.
I know that's a lot of info but it's the minimum you would need to know to safely use these lipo batteries.
rambo911, I don't let mine go below 3.5v per cell when setting up my KK2 alarm. That comes to 10.5v when the alarm goes off. Once landed, and battery removed (no power being drawn) they bounce back to around 3.7v per cell perfect for storage. So, if you have a way to set an alarm, that would be where I would set it. Otherwise you can use a voltage alarm buzzer (usually with LED indicators too). Most of those have a 3.5 cut off. If you have programmable ESCs, set them for LiPo and Medium cut off.
well that would depend on what cell cound it origonally had i it came with a 3s batterey then no you will burn it out but if it did then yes it will.(if it has a xt60 on it.
1 thumbs up!
This pack is just GREAT - the best I ever had! First of all, the cells are EXTREMELY well balanced. Even after discharging to 10pcnt residual capacity (which shouldnt be done, I know, I know -) ), ALL 4 cells had exactly the same voltage. Awesome. Whats more important, however, my Squall does not only have more power, it has more power for a longer time. Finally, after the flight, the pack is much cooler than conventional packs. Just buy it!
perfeita, mesmo quando descarregada perto dos 3 volts no desbalanceia.

I ordered the Turnigy nano-tech 2200mah 4s 25-50c batteries and i have to say i am quite pleased with them..not only did they get them here in the US 3 days after i ordered with the express shipping but they are in perfect condition..Havent tested them out yet still waiting for my plane to be built but im sure i wont have any problems, seeing as most people in my club already use the Turnigy Nano-Techs...
