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 who love graphs, it means higher voltage under load, straighter discharge curves and excellent performance. For drivers it spells stronger throttle punches and unreal down the back straight performance. Excellent news for serious drivers! 

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: 4200mAh
Voltage: 2S1P / 2S Cell / 7.4V
Discharge: 25C Constant
Weight: 222g (including wire & case)
Dimensions: 138x47x25mm
Balance Plug: JST
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. 

  • Capacity (mAh) 4200.00
  • Discharge(c) 25.00
  • Max Charge Rate(C) 5.00
  • Length-A(mm) 138.00
  • Height-B(mm) 47.00
  • Width-C(mm) 25.00

They go vroom

Dec 17, 2020

They are fantastic. Only gripe are the connectors. I use Deans, I had to change the connectors over. Other than that they have changed my life for the better. My life was in the dumps until I bought these. Thank you Hobbyking, you saved my life!!!!!!!!

Do not fit Tamiya Comical, Wild WIlly!

Apr 28, 2020

I bought these lipos, for a new Tamiya Comical, because of its round shape. However i came to the conclusion they didnt fit.

Great battery

Mar 29, 2020

Got these just because they were inexpensive. Ran them in a heavy load 160A 1/8 scale that REQUIRES higher rated C batteries otherwise it will trip thelipo low voltage cutoff. Got a solid 10 minutes of running without tripping the cutoff, a first for any of my 25C batteries. Nano-tech batteries are always performers. Best bang for the buck hands down.

Beauty and the Beast in one package

Sep 09, 2019

The design and scale detail is really good. The electronics should be improved, since the BEC is not able to handle the retracts when the EDF is working. Some servos are humming and one flap died after just a few flights.
The plane is really nice, easy to take off and fly but a nasty landing behaviour. It's very sensitive to the CG position, be careful when swapping batteries of different weight.
Adding a center LED afterburner makes her shine even on sunny days.
Well done HK! We are waiting for the F-100 to have a contender.
