Suited to the following models: Hirobo Lepton EX, HIROBO SDX-EP(4S x 2)


More than just a fancy name. TURNIGY nano-tech Lipoly batteries were designed from the ground up with serious performance in mind. Utilizing 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.

Lithium Polymer batteries are used in many RC hobby industries. Over the last few years, Lipo batteries have become the most popular battery choice for anyone looking for a longer run time and higher power.

Lipo batteries weigh less and can be made into almost any size or shape. Lipo batteries have higher capacities, hold more power and have a higher discharge rate, meaning they pack more punch. For safe use and storage of Lipo batteries, you need to follow the rules and treat the batteries with the respect they deserve.


Capacity: 4000mAh
Voltage: 4S1P / 4 Cell / 14.8V
Discharge: 45C Constant / 90C Burst
Weight: 485g (including wire, plug & case)
Dimensions: 168x49x29mm
Balance Plug: JST-XH
Discharge Plug: XT90


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) 4000.00
  • Discharge(c) 45.00
  • Max Charge Rate(C) 10.00
  • Length-A(mm) 168.00
  • Height-B(mm) 49.00
  • Width-C(mm) 29.00

Great battery

Oct 25, 2022

These Nano's are fantastic. One of the guys I have been teaching has several of these as well as Smart and Admirals. All are 4000 4S with similar C ratings. The Nano's run at least a full minute longer than the Smart or Admirals, 7 minutes compared to 6. And have more left when finished. This is typical of all the Nano tech batteries I have.

good battery

Sep 22, 2021

these batteries are very good. keep only half charged. they last a long time.had some for 10 years. people still ask how many cells does that plane have?I dont run them low. case closed. always blinky balanced.

Excellent battery

Apr 22, 2021

Good battery that holds charge well. Fitted to Avios Bushmule and is perfect for centre of gravity balance without extra weight. Power output is good and look forward to using it once Covid restrictions permit.

Erfüllt den Zweck. Bekannte Nano-Tech-Qualität. Meine haben nur eine geringe Zelldrift und sind bei richtiger Pflege auch lange haltbar. Ich bin mit der Technologie dieser Zellen zufrieden, auch wenn sie größer und schwerer sind als teurere andere Marken.
