Turnigy nano-tech 850mAh 3S 45~90C Lipo Pack (US Warehouse)

Turnigy nano-tech 850mAh 3S 45~90C Lipo Pack  (US Warehouse)

More than just a fancy name. TURNIGY nano-tech Lipoly batteries were designed from the ground up with serious peformance 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: 3S1P / 3 Cell / 11.1V
Discharge: 45C Constant / 90C Burst
Weight: 73g (including wire, plug & case)
Dimensions: 55x25x31mm
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.

I just received two of these, and they both weigh in at 82g, not the 73g stated. They're also 26mm wide, not 25 as stated. I can't use them without adding 10g to the tail of my micro jet and sanding the battery tray wider. (Skyangel Mirage 50mm EDF, balance is critical on this one) Is this common to have so much error in the weight stated? Is it worth the time, effort and hastle to contact customer service and try to return these? Thanks!

i have an axial xr-10 with twin 55T motors the battery is pretty well protected and weight and space is an issue
 Christopher 5 points
I'm using these on my XR-10 comp rig,.. With the 850mah sitting on a Rowdy Racing Battery Tray the 850's are about even with the top of my tires (Boss Claws), so this battery fit's fairly well and is still fairly well protected in the event of a roll over. The 850 makes for a good practice battery, I get around 15 min run time and with 35t holmes crawlmasters and dual Tekin FXR's,. for a comp battery you might try the 450mah 3S which weights about 1 ounce less than the 850mah, and has a narrower profile.

would these survive in a twin motor rock crawler?
 AndersKoll 45 points
I have fumbled these around and crashed them and never gotten puffy. Your rock crawler is more than a battery, look into the torque on your motor. 45c may be overkill...but if you're already willing to spend the extra cash, you might as well look at the turnigy hard-case lineup. More durable for your application. 850mah is also pretty small...don't know what you're driving though.

Perfect akku for T-Rex 250 DFC. Just amazing power and very constant voltage during flight and in combination with good ESC you will have no problems. I can recommend this akku and here is a convincing test video of my T-Rex 250 DFC for you.

Will these fir my trex 250 ?
 The-RC-Maniac 10 points
Yes, these are a perfect size for the T-rex 250 and clones.

Battery Seems Very good, Charged 850mah at 8amps... took 6min 30second to put back about 700mah back in (wasn't totally dead)... Flew with the same power as the 1c charge rate... Highly recommend these batteries

Another awesome nanotech! They can be charged at 10c(which means fast ) they balance easily and perfectly, the discharge is awesome. I used these to hit 120mph on my funfighter seafury. The batteries take abuse and keep coming back for more!

Awesome battery for the HK250 gt I get 7 minute flight time with this battery It fit fine with the stock canopy. Fiberglass canopy works but need some modifications.

While they do look like a quality battery, they do not live up to the specifications posted. I just recieved 2 of these and was disappointed to find that they both weight more than stated and are wider than stated. Both of the packs I recieved weighed 82 grams, not 73 grams as stated. This was verified on 2 different gram scales. Both of the packs I recieved were 26mm wide, not the 25mm stated. The other specs appear to be correct. I haven't charged them yet and am debating if it's worth my time, hastle and cost to return these. I had planned to use these in a Skyangel Mirage 50mm EDF Micro Jet but they will both throw off the balance and fit too tightly in the battery bay. If only they were as specified. The description below is the advertised specification with asteriks next to erroneous items along with the actual measurement. Spec. Capacity: 850mAh Voltage: 3S1P / 3 Cell / 11.1V Discharge: 45C Constant / 90C Burst Weight: 73g (including wire, plug & case) **** The 2 I received were both 82g. Dimensions: 55x25x31mm ***** The 2 I received where 55x26x31mm Balance Plug: JST-XH Discharge Plug: XT-60
