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

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

More than just a fancy name. TURNIGY nano-tech Lipoly batteries were designed from the ground up with serious performance in mind. Utilising an advanced LiCo nano-technology substrate that allows electrons to pass more freely from anode to cathode with less internal impedance. In short; less voltage sag and a higher discharge rates than a similar density lithium polymer (non nano-tech) batteries.

For those that love graphs, it means higher voltage under load, straighter discharge curves and excellent performance. 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!

Capacity: 4000mAh
Voltage: 3S1P / 3 Cell / 11.1V
Discharge: 25C Constant / 50C Burst
Weight: 333g (including wire, plug & case)
Dimensions: 173x49x20mm
Balance Plug: JST-XH
Discharge Plug: 4mm bullet-connector

Advantages over traditional Lipoly 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 1.2mO compared to that of 3mO of a standard Lipoly.
• Greater thermal control, pack usually doesn’t exceed 60degC
• Swelling during heavy load doesn’t exceed 5%, compared to 15% of a normal Lipoly.
• 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.

The nano-core technology in lithium ion batteries is the application of nanometer conductive additives. The nanometer conductive additives form ultra-strong electron-conducting networks in the electrodes which can increase electronic conductivity.

These additives create the 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.

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 29 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 this if you care do spend the extra money to charge multiple batts at once and buy a 12 volt power

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

Lots of power. Good price TURNIGY MEGA 400W V2 Lithium Polymer Battery Charger (Version 2)
 cmoon1498 11 points
Kyler is wrong. The Maximum charge rate is 5C. A 4000mah battery at 5C would be a 20A charge rate.

Why is this battery physically bigger then the 35C version?
 kaptondave 692 points
Because the higher burst discharge capacity requires larger plates.

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?

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.

The leads are 12 gauge.

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

Perfect for my FW440 with 9 or 10 inch blades, AND this also keeps my SkyEye aloft for quite awhile. Love the nano techs in general for their longevity and pep.
