Can we get some feedback on the Nano Tech Lipos Please

[Jahay]

there has been an increase of usage of the nano tech lipos 45/90c discharge.

I want to know what people think of them and if those ratings seem realistic?

I have asked many people to get back to me regarding them and no one has said anything...

I take that as a good sign, because you only usually hear about the bad things...

So i am hopeful, but i really want to know is if these discharge ratings are accurate and how ridiculously they perform! 90C Burst!!! THAT SHOULD BE MENTAL RIGHT?

Thanks

I have got the 25-50c 6000mah 4s nanotech. It performs great, I can't really tell the difference compared to my other 4s packs, including the new Blue Lipo 4s pack I got. I think the only real thing I notice is I can charge it at 10 amps all day everyday.

[Jahay]

hmmm thanks for chiming in... at least you have nothing bad to say about them... 25/50c really isnt anything special so i doubt you would have noitced much difference...

im more interested in the 45/90c packs... and if someone has tested them against some 35c hyperions and can compare them, that would be even better..

[reno911]

I am thinking you are looking for a response from someone say that does speed runs, or pushed the living crap out of a pack, racing and bashing, I figure you'll never probably see the packs full potential.

[Jahay]

yep exactly reno... there is so much hyp about these 45/90c ratings... and because of all the B*llS*** of hobbykings actual C ratings, i just want to see if they are worth the money...
Otherwise some normal 40c turnigy lipos may be just as good...

My current 35c hyperion lipos are extremely powerful.. .they outperform any 35c lipo i have tested from hobbyking so far, including some expensive lipos i bought here in the UK from a reputable seller which cost me just as much as my hyperions (problem is, hyperion lipos are crap in terms of their soldering!!!)

im hoping someone who has done an xxl length truck or some sort and can actually put the power down rather than wheeliing the whole time, can tell me their experience with these big boi lipos???

Honestly, I really like all my Turnigy packs as well. They've all performs brilliantly; however, they've never matched the performance of the Hyperion G3's.

In your case, if you are looking for the extreme, proven performers why not get the Hyperions 45c packs? You know they will be worth it.

[Jahay]

yes they definitely will!!! (i actually believe they would be too much in terms of punch causing everything to fall apart haha... they are expensive though, and as i mentioned already... the quality of hyperions is absolute crap IMO, their soldering seems to have been carried out by a 3 year old!!! i did better soldering when i was 11!

This is why im interested in these nano techs... if they have the quality of the turnigys but the proven punch they state, then thats WIN WIN in my book!!! great price too!!! at nearly half the price of hyperions!!!

Plus i will be running 9s and 3x3s hyperion lipos is a lot of Monies to part with

Hyperion Quality Crap???

I have seen their packs, wished to own one. They are far from crap. I feel that they, if anything, set the standard of what RC lipos should look and perform.

However my budget allows for lipos within my budget, and when I race the cheap Blue Lipo holds up just fine in my 4x4 next to those running maxamps, zippies, and hyperions.

I would assume at that voltage your motor and ESC will be working with less amperage anyway. Though having the most available does make sense, you could just calculate what is needed and shoot for 100 to 200 amps more than needed for some wiggle room.

[Jahay]

have you seen their soldering jobs??? here you go buddy pic below...



my mate ran hyperions and his soldering on his is exactly the same...

After 30 runs or so the lipos have only been getting stronger and stronger and perform amazingly, but now they cease to work... im going to reflow the solder with a soldering gun hoping this will repair any possible cracks from impacts and allow the lipo to work again, but my mate has experienced the same problem too....

What i am saying is, i still love these lipos and they do perform unbelieveably, but for the money, i wish they were put together a little better.

Turnigy and Nanotechs, are amazing prices, offering decent quality for the money and performance. If somoething does go wrong with them, you cannot be too unhappy as you havent forked out an arm and a leg for them... catch my drift?

[reno911]

Remind me to post a pic of a Zippy when I get home. Or any pack, they look the same.

I really must not have seen enough open lipos because as far as I can tell there is nothing wrong with that picture other than possible needing a cleaning, and it is missing the - lead.

[Jahay]

the negative lead is on the opposite side...



ill remind you... i would like to see how the soldering jobs compare

[pinkpanda3310]

Bear in mind the 45-90c rating of nano will mean little if you are not satisfied with the solder. Plus you run 9s yeh? Do you have a logger? If you do then you would know if you are using the limit of your current (now) batteries and or what the system draws. Then (as stated) get a battery that has lots of head room.

[reno911]

Okay so the neg side looks pretty bad, though the cells themselves, at least, look to have been soldered well. The balance tabs not so much, cold joints for sure. i would just get the iron out and heat them all together.

I searched my image hosting and I thought I had a pic of one. I have a zippy open at home I will surely take a picture of it when I get off.

How much currant travel through the balance tabs anyway? Shouldn't you really be worried about the leads, which both look to be well soldered.

[Jahay]

i currently run 6s on my MMM, but just doing my homework for when the new MMMHV is available... So i have no data logger at the moment, but i will make sure to get one when the new ESC arrives...

I am definitely using the most out of my current lipos... thanks to my xxl chassis and the weight at the front of the tvps, i can put all the power down without much chance of wheelies... and the new centre diff also helps keep the front down too...

Honestly, i have seen graphs from a data logger, and dont really understand what they are representing, but i guess i will pick that up as soon as i get one..

edit
reno - i believe there is a break somewhere... i do not have a multimeter so i cant determine where the break is, but someone mentioned that the neg side was not looking so great and i should just reflow the solder... So ill do that tonight and i am hoping that sorts my problems... FINGERS CROSSED..

[pinkpanda3310]

Is the mmmhv going to have logging built in like the ice range? If so (I hope it does) the logger you get will be redundant soon unless you have other smaller rc's. Plus going from 6s to 9s should be lowering the amp draw on the system anyway.
