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!
*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.
Got this battery with a HK-10A esc and a 1811-2000kv bl motor on a converted hawksky mini.
Gives me about 8-10min flight time, depending on flight style.
Would be great if i could charge the battery faster than 2C, so that i could recharge one battery while flying on a second one *)
If i get someone to film me flying, i will post a video *)
Edit: Made a adapter cable for my Accucell6 to charge two of them together as a 4S pack hehe.. maybe i make a 6S adapter as well..
Oh and please guys.. i've seen all those comments or requests about changin the plug of the battery... Just make an adapter cable which fits between the battery and you are futureproof if you buy a new battery with an completely different plug or you may buy a new model which has a different socket... just keep the stuff you have original and make adapters... saves alot of hastle or warranty voids... oh and saves you quite some time/work if you have chests full of batterys which you want to 'modify'....!
Got a couple of these for the Losi 1/24 Micro. These things are great. Lots of power and run time. The little red plug needs replaced with Losi or vise-versa. I just soldered up an adapter cable. Great little batteries.
I use these in my mCPX BL. They fit nice. I dont use the stock E-Flite charger. I have a 6s charger w/ balancing board so no need to cut any plugs off the battery instead just change out the plug on your heli to a Red JST!
First of all can I say these are excellent packs! Big improvement over stock eFlite cells/packs, however I would like to see these fitted with the UMX connector for the UMX series of models or an adapter lead to convert from JXH to UMX?? As I say these are a great pack and you would sell thousands for UMX models if the correct UMX plug was fitted. It is of course possible to fit a JST to the model but a 'Plug-n-Play pack would be VERY popular indeed!
It is perfect for small foamies. As you say...when shrink and balance oconnector is removed, it has no competitor comapring weight to capacity. Its weight is similar as standard 180mAh 2S lipos. Best choice.
I BOUGHT 3PCS. THIS FOR USE WITH BLADE 130X HELI. Claims to be 35C All 3 went on voltage cut-off in less than 3min (3.3V) flying 3D. The power is so muck less than the stock EFlite 30C (300mAh also) which last for 4min on 3D flying. Don't use this lipo on Blade 130X, it will get hot quick and is not good on the lipo.
These batteries can be charged with more then 2C. I havent notice any capacity loss charging it 4-5C. Most of lipos sits well with up to 1C. High discharge (like this one) usually 4-5C will be always ok. Chargiing with higher current, will not shorten charging time too much, because of balancing and final period of charging, when current is steadily reduced to zero(it takes similar time during 1C and 5C charging). To sum up, 5C is ok, just inspect if they dont heat up too much.
Hi HK, I would like to see these with the UMX connector for the UMX GeeBee, that would be great! That way, for the price of one of theirs and a the corresponding 5 minute flight you could get 6 of these and closer to 45 minutes of continuous flying.
Depends, I haven't checked temperatures so it may be fine. I was just drawing an analogy, maybe I should have said "total flight time". Not only do they have 50% more capacity than the stock battery but you can get 6 for the price of 1. So if we assume that the stock give 5 minutes then we have 5 X 1.5 X 6 = 45.
Sure, but on small batteries like this it is delicate work, not for everyone and if you don't have the crimp tool it may be near to impossible. Also, if you get an adapter you would probably be adding a total of 3-5 grams due to extra connectors and wires, that is 15% - 25% the weight of the battery. I'm just saying that HK has a good opportunity here if they offer this same battery without the JST and with the UMX connector on the balance tap.
Actually, probably not. In the UMX planes the connector is attached directly to the mother board which is typically an integral part of the airframe (you mostly have to destroy the plane to get it out). I don't know about most people but I would certainly not want to be soldering anywhere near all that thin and fragile foam.
u do not have to destroy anything to get to anywhere in an ultra micro plane...they r designed to be serviced, and therefore u can remove and install any elecs by simply cutting a little tape at the seams (fuselage halves r held together by a few strips of tape, not glue). the brick is only secured by 4 drops of silicone like glue at the corners....modding these things r pretty easy...u can swap out all the guts and put the plane back together AND have it still looking brand new in under an hour
That may hold true for some of the UM's but is sure isn't the case with the GeeBee. Even Horizon states that at best you can repair the landing gear, otherwise you are better off with a new airframe. sfactor1, I get it that you are interested in making this battery work and that is great for you. However, I have no interest in doing any of the things you propose, I want a higher capacity PNP battery and this could be the one if HK would release it with the correct plug. For now I guess I will stick to 240mAh Hyperions.
if u damage an airframe (airframe means NO ELECS) and u want to swap out the entire airframe (not necessary )u have to do exactly what i said. but of course u DO NOT HAVE TO TOUCH THE AIRFRAME TO USE THIS BATT. just change the connector ON THE BATT. i have worked on ALL of horizon's um planes except the easiest 1's (hypertaxi, vapor, geebee). the hardest 1 is of course the beast with 2 wings, struts, flying wires etc. the geebee, being the largest um, should be 1 of the easiest planes to work on. i do realize u do need decent dexterity, and a steady hand to work on um's (sorry if u have health issues), but if putting a knife to foam, using a few mm of tape and literally a couple drops of glue is too daunting a task for u, u could always pay the lhs or anybody thats into arts and crafts to do this for u (the $$$ saved in batts should cover this cost.) remember, U DO NOT HAVE TO TOUCH ANYTHING ON THE PLANE TO USE THIS BATT. just change the connector ON THE BATT. look on ebay for "micro jst ph 3 pin" (PLZ PLZ PLZ STOCK THIS MR HK)and install that connector (which is the eflite connector) TO THE BATT. I.E. U DONT HAVE TO MOD THE PLANE
Thank You HobbyKing! A small 2s battery in a size and shape that actually fits inside the fuse of tiny foamies.Nano-techs are my preferred batteries-haven't puffed one yet, noticeable power difference.
