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.
Unfortunately with other big brands, numbers, ratings and graphs can be fudged. Rest assured, TURNIGY nano-techs are the real deal, delivering unparalleled performance!
Spec. Capacity: 5100mAh Voltage: 2S3P / 2S Cell / 7.4V Discharge: 65C Constant / 135C Burst Weight: 130g EA (290g Total Inc Wires) Dimensions: 69x47x25mm EA Balance Plug: JST Discharge Plug: 4mm Bullet-connector to your own custom plug
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.
So I was running these in my pro 4 truck for the first time and melted the plastic around the connections going to my esc. As soon as I finished my race, hit the first double after the finish and the truck stopped. Took a look and it also melted my solder connection negative side right off the post. I noticed in practice that these packs were running hotter than my other packs but didn't think nothing about it
Will this pack fit Durango DESC410R short course truck? I think it will, but if anyone have some experience with this issue it will be very helpfull for me.
Went in my DEX410R with no problems, I could change the pivot point of my upper holder by changing the hole that my pin went thru. Very good packs for the money.
today i charge my battery, using eco 6 charger. my rate only 5c . when battery was full i touch my battery 1 pack hot and 1 cool, what should i do, is it true there are reverse polarity problem, how do I handle? my battery is new I only used 2 times :(....... help me guys
You should be fine. I've done this a couple of times and been OK. Let the pack cool down and check them for any major swelling* if there is any I'd play it safe and dispose of it.
I always charge at 1c so that may be the explanation why. I'm a racer and not a basher and it's the recommendation of my national body to charge at 1c, so I do.
If you have ANY doubt over the pack* dispose of it.
At the end of the day it's your choice my friend, I've given you my advice based upon my experience with RC over the past 15 or so years. Personally I wouldn't do 10C, not even 5C to be honest but then I'm conservative by nature! The last time I had a battery come off charge at that temperature is was a 4500 IP NiMh...... If you're not happy with them send them back for a replacement and explain fully what the problem is.
Also, is it this charger www.link is that's less than 1C for those batteries as it only goes up to 5A charge currant, 5C for those will be 25.5A charge currant. If so there is deffo something wrong with the pack and you need to send it back.
To fit these in a mid motor truck like the 22T, do both of them fit in the battery tray, in the case that they must be run together, ie two 1s 5.1ah saddle packs? I would think this would be unnecessarily heavy compared a single pack but the tray has such an odd size . Thanks in advance
There weight is very close to a stick pack of the same capacity, I'm currently running these batteries in a 4x4 1/10 buggy with a boosted 8.5. I have no problems making a 8 minute main and I don't feel any voltage sag throughout the race
Can anybody who ACTUALLY HAS these please inform us as to what voltage each pack is? Everybody is saying different things and I'll bet none of those people have the packs because it's very easy to tell. Is each pack a 5.1ah 2s as the picture would imply? Please do not respond unless you have these packs.
Each cell is 5100mAh 3.7v (nominal) so they are 1s per pack.
When you connect a battery in series (which is what you do with the link wire, making a 2s pack) you add the voltages together but the capacity stays the same* hence them being sold as a 5100mAh 2s (7.4v) pack.
You can (and I do) use an individual half of a saddle pack in a 1s application (such as in a Mardave)
If I order 3 sets of these and wired them in series I'll have a 6s\65c-130c at about 850 grams right?
If so the price and weight can't be beat with 2 sticks!!!
What voltage are these holding at 100amp discharge after 10 cycles?
Is each pack a 5100mah 1S pack which you run in series to gain 5100mah 2S?
or
is each pack 2550 2S packs which you have to connect in parallel to get 2S 5100mah?
it's a 7.4v 2S saddle pack. It's exactly the same thing than classic 2S stick pack, but in 2 parts, each part is : 1S Why ? because if you' re running a 4x4 1/10 like : B44.1, or durango DEX 410 you need saddle pack, because classic pack doesn't fit in. I use it in my Losi twenty two in mid motor and rear motor configuration. it perfectly fit. I hope my aswer help you.
Right, does anyone here ever tried to charge a battery like this with 10C(51 Amps)? Does the battery hold up? What kind of a charger requires for this? Any recommendation?
There are others that do quite well on charge current.. For example the other Icharger's with 20A or the Turnigy Mega 400W with 20A...
10C charge for a 5000mAh pack however is not possible yet.... Give it some time tho , i'm sure they will start making them with all the advances in battery as well as charger tech being made.
Yes they fit sc10 4x4 if used them once when i forgot to charge my "stick pack" but unless you running Durango SC or 4WD buggy or losi 22 in mid mount config why are you even lookin at these you should be looking at hard case stick packs there is one 6000Mah 65C that will fit like a glove
Mikeylama: Not sure if your trolling just to get a post count/lucky post... but I can't think of a single "safe" 10C charge scenerio or the reason to do so. Although it is more common to charge at 2c these days (it's still debateable if it shortens the life span of packs) ... a 10C charge is strongly strongly discouraged. If you do attempt this, please, stream it live (or post it afterward-if your house is still standing)to YouTube, so we can watch the show.
Very good for 1/10TT. Use it on my X-Factory X6 2 with a LRP X12 and nosram pearl and it rocks!

Can anybody write and confirm: how much weight is one cell and exactly which size in milimeters is one cell case?
Is the same, what HK writes in desription or not really?
Thank you.

Placement of POLARITY IS VISE VERSA to standard. Be carefull it may require to extend your wires and other inconvinience. Fit DEX410 perfectly except this polarity issue.
