Turnigy Nano-tech Vs Standards ? ?

[Randall]

Hi all

Well currently im flying with Turnigy 3000's 6s 20c and well the rex Flies much better than the Align packs. im getting 7 mins of fast sport or 6 mins of stick bashingputting back about 2000mah.

Now im starting to really pull some full collective moves for long periods of time and i am getting my headspeed to drop so it could be the motor but im on a 12t pinion so not really too likely. (im going to get a 13t shortly)

So im thinking that the packs might not be as good as what they could be for really thrashing the 500.

What are peoples opinions of the Turnigy Nano-techs ? im very very happy with the standard turnigy stuff as they come down much cooler than the align 25c stuff and dont puff either (so far) and defo have more power too.

Im thinking of trying these HobbyKing Online R/C Hobby Store : Turnigy nano-tech 2650mah 6S 45~90C Lipo Pack

There 45-90c 2650's thats near on 120amp constant there claiming so at 60 amps the voltage should be not dropping too much right ?

Im always a bit hesitant to belive there claims but i must admit with there packs they have supplied me so far i have no reason not to trust them. However i have heard a few negatives about the nano-tech packs. Is it a case of the usual 5% are going to be Dead ?

All suggestions welcome. (im not into buying extremely expensive packs any more i used to buy flight power packs and they let me down so many times with poor performance and early death i now take the view of buying cheaper packs and replacing every year or so means i always have fresh packs)

Hi Randall,

I can't answer about the nanotechs (I too have heard worrying things about them, but there's so much selection bias). Your last point though is one I'm about to investigate myself. I just bought a genny thinking I'd get one (maybe two) Thunder Power G6 packs per battery size and just fly those. On paper it should work out cheaper and better than using Turnigys - better performance, more cycles per quid, more power throughout the discharge.. can't lose, provided that 1) They're not too optimistic in their specs, and 2) You can recharge at the field.

It's point 1 that worries me.

Would a governor help? My ICE 100 pulled a Turnigy 6S5000 down to 3.4v resting on Saturday (LVC, crash) and I never noticed the head speed drop (550E at 2100 RPM). The battery came out hot and puffed but I can't blame it in this case as I discharged it so deep (not sure why..).

Regs, Tom.

Hi Tom

Well i guess maybe my experience is very rare but having used LOTS of lipos in many fixed wing models and RC cars (where they take the most abuse) and my end result is what ever pack i have it never seems to last 2 years of my abuse. I do alwyas balance charge and never over discharge. always store correctly. but i just seem to get poor performance packs after 18 months to 2 years. i must admit i do use them alot i guess my 500 gets 15 flights a week in total (perks of having a field at my front door) but still what ever pack i buy looses performance after 2 years. and for the price of one thunder power pack i can buy 3 or 4 turnigy packs meaning they only have to do quarter of the cycles to be value for money right ? + i would not want to bother charging at a field tbh when i go flying i like to take my 6 packs or so and just fly and go home. charging on site just does not appeal to me

[davie]

personally i wouldnt be to bothers if after 18 months the battery that was getting used alot every week failed that is still a lot of cycles per pack ,,,, how long do you think they should last if used regularly 18 months isnt that bad in my book

[NiceBlades]

If your doing 15 flights a week with 6 batteries thats 1560 flights over 104 weeks i.e 2 years, so if you have 6 batteries thats 260 cycles! I think 200 cycles is very good for a lipo, don't think I get that though and I'm just sport flying my 3000mah 20c Turnigys, yes they have puffed but still give 5 mins and are 2 years old this summer. I guess I average 2 flights a week as I can't get out every week, I also run phoenix 80amp esc 13 pinion.

[Randall]

I guess when you do the maths its not to bad, i have not had the turnigys two years so i cannot compare yet bit so far they have ben great and already have been cheaper than running a nitro i think actual age also plays a important point in a lipo not just cycles i have nothing to back this up appart from my limited experience but some of my lipos that are a year old with less cycles than some of my packs that are 6 montha old have less performance. So maybe ages plays a bog part not just cycles. Im still happy spreading the cost of my lipos with turnigy stuff as i fly so regular :-)

Sorry to jump on your thread but im also on the lookout for a new batt for the 500 as one of mime dies after around 1 min into the flight (Turnigy 2650mAh 6S 20C) the head speed drops right off & the tail begins to pulsate but then when i check the pack there's still 77% left in it.. so im guessing its had its days.. ive also had it around 18 months but prob at most only had 30 ish charges on it so would have expected more from it.. .

anyhow, i was waiting for the Turnigy 3000mAh 6S 30C to come in stock to give these a go next or even stick to Turnigy 2650mAh 6S 30C that ive also got & up to now has worked well with around 20 ish charges on it.. BUT now after seeing this post i dont know if to give the same as you've been using a go Turnigy 3000mAh 6S 20C as for one reason they'r near on a tenner cheaper than the 30c & have them in stock...

can anyone give their opin on which would be ok for me.. im not into 3D yet.. just the od flip or roll every blue moon.. other than that i just fly nice n steady all the time with it..

thanks.

Personally, I havent found that higher C ratings give better performance (on HK packs).

I have found that they come down cooler though, which in theory should extend the life of the pack.

I tend to use the 20c packs, as they last me for at least 9-12 months if charged by the Cellpro. Will a 30c last that much longer than that? Prob not, so I couldnt justify paying the extra.

[NiceBlades]

BaRoN30s I have been very pleased with my 3000 20c lipo's, I'm not buying more due to buying the new 600efl pro and want more capacity so waiting for the 3300mah 30c's or 35-70c nanotechs to be in stock. I think for the money you can't go wrong with the 20c 3000's, I might end up getting a couple more of these to tie me over as hobbycity seem to be taking a long time to replenish stock at the moment especially in the German warehouse and as you say for the moment these are in stock. I'm also a sport flyer btw.

Baron (sorry dont know your name )

I would get the 3000 20c's even with some stick bashing and full collective they come down quite cool (luke warm) really good packs IMO perform great. I would not invest too much cash into Turnigy lipo's tbh for what you are doing the 20c's will be more than enough

for the price of one thunder power pack i can buy 3 or 4 turnigy packs meaning they only have to do quarter of the cycles to be value for money right ?

"According to the specs" the cycles/£ is better on a Thunder Power (600 or 800 cycles, I expect that is usually read with a raised eyebrow), but I've heard so many different figures for what people say they've paid for their Turnigys. They've cost me £80 per pack including shipping and taxes, and it's only twice that for Thunder Power. But with TP you get a better flight too. Maybe, who knows, this is me repeating marketing information which I thought I'd never do

Have you tried a Thunder Power pack recently? I'm assuming that's the gold standard.

Charging at the field? Ah well, what else ya gonna do between flights (I need a good 15 minutes to recover!). At least I can plug a kettle in

I have got a couple of nanotech 25C 6S 3300mAh lipos and to be honest I am not that impressed. They have been stored/charged correctly but they have started to puff after about 20 cycles and the IR of a couple of cells in 1 pack has increased by 50% (4 cells are at 4 mohms and 2 have increased to 6 mohms).

When I buy more lipos it will be standard 30C 3000mAh turnigys from Germany. I personally dont think the nanotechs have been worth the extra money tbh.

LOL i go indoors take off patch 100 feet from front door hehe.
Well i would like to think that thunder power could do 800 cycles but until some one has achived this in real life and not on a test bench i will refuse to believe there firgures as i dont trust marketing/sales documents. i have no doubt they will perform better tho and there 2 year warrenty does sound quite nice (does this get voided if you change the connectors ?) maybe i will buy one of there packs and put it along side a new turnigy pack and monitor the pair of them. Im not arguing the facts i just simply dont yet believe the claims if they really are that good i might be tempted. its about time a new chemisty came along and gave us a long life pack with better performance..... Oh the dreams lol.

thanks bolders this is the kind of feedback im after. i hate puffy lipo's i just dont trust them lol.how ever they do make fantastic air rifle targets. You know when you have hit target !!!

My Nephew has a nail gun that hes gonna bring down with him next time he visits and I have got some old lipos waiting lol.

TBH its not the puffy packs I mind so much its the big imbalance in the cells IR (although the 2 issues are probably related.
