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!
Suited to the following models: ALIGN T-REX250, GAUI EP-200 V2, E-SKY LAMA V2/V3/V4
* 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.
I use these lipos ,but they are taking really long to recharge at .85 amps.Can these lipos be safely charged any faster at a higher rate without risking any damage ?
I am using a turnigy Accell 6 charger.
Hi Larry, Max safe charge rate on these (and other nanotechs) is 5C, which is 4.25A. That said, there's max "safe" charge rate (you won't cause them to go exothermal and catch fire) and there's max reasonable charge rate. Based on nothing more than personal opinion/experience, I wouldn't push your charge rate much beyond 2.5A (15-20 minutes to fully charge), as any more is pushing them pretty hard and they start getting very warm. Cheers, EA!
Hi being new at this new and exciting hobby I just do not want to make any mistakes. Not long ago I was in a very very bad plane crash. Flying was my hobby for some 25 years. On Drs and my wifes advice I am taking up flying with my feet on the ground.
Thanks everyone for the help.
Hello, I like these Lipos but Iam having a problem with the JST discharge plug coming off leaving the metal fittings exposed. Also the jst plugs are really hard for me to line up with the other one. I can not squat or bend over very long due to health problems from a very bad plane crash.What would be a good replacement plug to use with the small wires the lipos come with?
I find these a little bit fiddly, but I never had the pins come out on me.
Perhaps a couple of small pairs of needle nose pliers would let you get an better grip on each side and give you the right kind of leverage.
XT60's are much bigger and more solid, perhaps they'd be easier for you to grip.
Hope this helps.
Hi Laercio, The V912 uses a 1200mah/2S LiPo, so this one would give much less flight time in that bird. If you want a nano-tech LiPo you should have a look at the 1300mah/2S (PRODUCT ID: 9210000041). It's the same weight but a little larger than the LiPo sold for the V912. Cheers, EA!
Hi kwarksys, Any decent LiPo charger will charge this battery. There is no "best" charger, but if you want the cheapest option that will get the job done have a look the HK DC-4S (PRODUCT ID: 9331000001) for only $8. This LiPo will work with the 1811 series of motors, but if you're going to run 4 of them in a quad off 1 LiPo your flight times will be less than 8 minutes. A bigger capacity battery would give longer times. Cheers, EA!
Hi, Iam using these lipos on a new build. Its called a towel.Its a simple to build wing made out of poster board, but takes 15oz of thrust and my motor is only putting out about 10oz. It flies but way under powered.Using these lipos what would be a ok motor that would give me the needed thrust?
I really like these lipos but need a more thrust.
Hi Larry, A general rule of thumb for motors is you want at least 150W per pound to get enough thrust for fully aerobatic with some vertical performance. I know you're fairly new to flying RC, so you could start off with about 120W-130W for the wing. Have a look at the D2822/14 motor (PRODUCT ID: D2822-141450). I use it on a 375g (13.4 oz.) 3D plane with the 3S version of this battery and it has been bullet-proof and an awesome performer. 1/2 throttle hover and rocket shot verticals. On a 2S you should see about 500g of thrust, depending on the prop, which will be plenty for your wing. P.S. Don't make the wing your first post-trainer plane. They're twitchy at best! Cheers, EA!
I have the HK 3D Hawk which the stock esc comes with a JST connector. The spec above states a Mini JST plug, however it looks the same and should be able to fit my Hawk's ESC JST Plug. But juz to confirm are they the same n be able to fit each other?
The "C" rating is a capacity multiplier rating. The capacity of this battery is 850mAh, or 0.850Ah. So, for example, a 25C discharge rating means that you can discharge it at 25x0.850A, or 21.25A. Look at the battery to see what the maximum charge C rating is. It is probably between 2-5. A 5C charge rate for this battery would be then 5x0.85 = 4.25A. A standard charge rating is always 1C, or 0.85A for this battery. So 0.3A or 0.4A are both well bellow that, and both are safe. Cheers.
We pull bad cells from batteries all the time and replace them with good ones. You have to be good at soldering to end up with what you want. Also, you need some thin heat shrink to wrap the battery in once done. This was just completed on my Turnigy 5000mah 3S. So, imho it can be done.
i've done it before with some 1800 mah batteries of my belt-cp, after a few flights a cell went dead so i just opened up the pack and unsoldered the bad cell and made the pack into a two cell for my glider, but if you're not at ease with electrics or are not that good at soldering i wouldn't recommend it, then you should seek someone with some more experience with soldering.
one more thing, try not to heat the tabs of the cells for too long or you might damge the cell you are soldering on...
I've split a 1000mah 2S battery before too because a cell was dad. Now I have a 1000mah 1S battery that works fine. However, you must be good at soldering, as you will need to reattach the wires to the thin, tinfoil-like battery terminals. Very important tip: ***if the solder does not stick to the foil terminals, gently sand them to rough them up, then the solder will stick and you can reattach the wires.*** Also, buy some 25-30mm heat shrink tubing to cover the finished battery.
Very good Lipo . Charge 5 with Turnigy X5 2S 5 port Lithium Polymer Battery Charger at 3A,charger get hot but Lipo still warm . Charge also same Lipo but GAUI and this Lipo get hot . Also last a while during flight and more than others .
these seem to have the same properties as the 40C rhinos which i also have. i love the 5C charge feature with these small sells. 1 or 2 packs give you unlimited flight time during the day, almost like with gas powered planes.
I just received 2 packs today. No charger yet as that's in another order that hasn't come. I measured all 4 packs with my DMM and one cell in one pack measures 0V (zero volts). I'm hoping hobbycity will warranty this. I know they measure them before they ship, so this is surprising. I hope I'm not screwed out of one pack as I need packs in pairs. I'll keep people updated on HC's response to my dead cell/pack
I got 2 packs dead after les than 10 charges. Forget warranty, you must claim it in the same day the shipment arrives and you should send back the faulty battery (in my country this cost almost the value of a brand new battery).

Recieved two packs couple days ago. Got two cycles on them today and they flew twice as long as I expected. Charged at 2C with no problem, curious what these can be charged at safely? HK states some of them can handle up to 15C charge rate
