Turnigy nano-tech 4000mah 3S 40~80C Lipo Pack (TRA2849 Slash/Rustler/Bandit/Stampede compatible)

Turnigy nano-tech 4000mah 3S 40~80C Lipo Pack (TRA2849 Slash/Rustler/Bandit/Stampede compatible)

*High performance replacement for Traxxas TRA2849. Will fit all current 1/10 Traxxas models. 

Add extreme power and performance to your Traxxas vehicle with this high discharge, high capacity TURNIGY nano-tech battery!

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!

Capacity: 4000mAh
Voltage: 3S1P / 3 Cell / 11.1V
Discharge: 40C Constant / 80C Burst
Weight: 321.0g (including plug & case)
Dimensions: 136 x 25 x 43mm
Discharge Plug: TRX plug
*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.

Bad batteries. Don't give full C on my 6-copter. Therefore low flight time, puffy and not full discharge.

I have a couple of these and they work well. I'm drawing about 650 watts out of them when I am near full throttle. I changed the plugs that was a little tricky, a high wattage soldering iron is best, fill the wires with solder first and some on the plug. Maybe put the female connecter together with a mail plug when soldering so that the heat less likely melts the plastic around the terminals. Don't forget to put heat shrink on the wires before you start.

Can i use this battery for a quadcopter? i'll just change the plug?

Hi guys does anyone know if two of these will fit side by side into an RC8.2e?

You will need saddle packs, these are not saddle packs. Saddle packs are smaller. They may still fit with some modification. Measure the dimensions of the battery trays and then look at the size of this battery. Don't neglect height either, is it can stop you from fitting a body on. Also, this is a 3s battery. If you want 6s, by connecting in series, then that is a lot of power, but if you want parallel, then you will only get 3s, and that isn't much for an RC8.2e

What cables do I need to get this battery into a Traxxas Rustler VXL?
 Adriano 2 points
you need no extra cables, plug and play

Ik gebruik deze lipo in mijn VITESSE een zwever van 3 meter en een gewicht van 2.6 kg. De motor trekt 55 A en ik heb 4.30 min looptijd. Zwever blijft goed stijgen tot de laatste seconden. Ik heb nog 4 van deze lipo's bijbesteld!
