Turnigy nano-tech 4000mah 3S 25~50C Lipo Pack (USA Warehouse)

Turnigy nano-tech 4000mah 3S 25~50C Lipo Pack (USA Warehouse)

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: 4000mAhVoltage: 3S1P / 3 Cell / 11.1VDischarge: 25C Constant / 50C BurstWeight: 333g (including wire, plug & case)Dimensions: 173x49x20mmBalance 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.

Does anyone know what charger is really good for this batter? I am using it for a tricopter. I am a beginner and this is my first.
 kenneth 27 points
you want something around 4amps or more... the more the better when your buying your charger as it can be used on all your future models and all your batteries. I would try to get a charger that can run on A/C power otherwise you will need a 12 volt power supply to accompany your charger. either www.link www.link this if you care do spend the extra money to charge multiple batts at once and buy a 12 volt power www.link

The maximum charge rate is 5, so half of the packs amps. 4000=4 amps /2 =2 amp charge rate.

Why is this battery physically bigger then the 35C version?

The right upgrade battery for my Walkera V450Do3

Did you have to upgrade your ESC? If not, how well does it perform with the original ESC, Does it overheat?

Do anyody know the guage?
 MrScsi 271 points
The main leads are 1/8 of an inch in diameter which they say is .1250 in decimal,And looking at a wire gauge chart they would follow in between 11 and 12. They don't get warm that much I can tell you. I run them on a quad (I have two and run them one at a time) with 21 amp motors and 30 amp speed controllers x 4 and they don't even get warm after 10 min. of flying.

Which adapter do I need for this battery - I need to connect to a male deans connector?
 Eagle34 6 points
You could either solder on a female Deans/T connector or get the HTX 4mm to T connector/Deans adapter.
 MrScsi 271 points
I just made my own adapter real easy...

Bought two of these for a 3s setup on my 47" wingspan foamie pylon with a turnigy 3536 1450kv 8x6E tgs prop. The discharge rate on these gives it huge thrust and instant rpm changes. Will update with amperage draws as soon as my wattmeter arrives

Bought 2 for my 550 quad (not both in parallel but who knows) they seem very well constructed and seem to have power to spare. The only thing is I may have to get a scale and weigh one because (and I very well could be wrong) 333g should be 11.7 oz and they seem a bit heavier. Now my quad will lift em without an issue and it gives it a good COG but it is the heaviest 11.7 oz I think I have ever held...

Better than the regular turnigy 4Ah because it is slightly smaller.

great battery for my 550 hex (using two of them) the balance plug wires are nice and flexible so far so good about 50 flights
