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: 850mAh
Voltage: 4S1P / 4 Cell / 14.8V
Discharge: 45C Constant / 90C Burst
Weight: 99g (including wire, plug & case)
Dimensions: 56x31x33mm
Balance Plug: JST-XH
Discharge Plug: XT-60

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) 850.00
  • Discharge(c) 45.00
  • Max Charge Rate(C) 10.00
  • Length-A(mm) 56.00
  • Height-B(mm) 31.00
  • Width-C(mm) 33.00

After some issues with dead cells, it was all sorted. I've only had a fly a couple of times and the batteries seem fine. I was impressed however with how quickly the issue was sorted and new batteries arrived.

Dang this battery has a ton of power.

Jan 10, 2020

I can certainly commend the battery, even though it's nearly flat and exploded. I crashed a Flite Test Nutball into a tree so hard it ejected the battery, and smashed into another tree 10 feet away, bursting into flames. Before this I was using a 3s battery and the plane was a bit underpowered.
10/10 would totally do it all over again for the cost of the foam+battery.

Best for 3 inch Quads

Dec 23, 2019

These are cheap and give a decent 4-5 min flight time on my Diatone GT R349 HD, the 650 is too small so shorter flights and the 1000 is way too heavy. The 850 is perfect, loads of punch and power in fast bursts, I have used them over and over for the last 6 months and the only ones I can't use are ones I crushed on impact in some bad crashes, all of them are still great. I like the square shape too, better than long skinny batteries. XT60 is perfect too. All round this is a top battery and great value.
