Turnigy Nano-Tech VS. Thunder Power?

[LuckyDuc]

Is this a fair battery test between Turnigy and Thunder Power packs?

[RaceMechaniX]

In simple-NO

[LuckyDuc]

I'm not convinced that it is a good comparison test either. It did get my attention though.

I race Thunder Power, XPS, and a Grim Speed Pack. I might try racing a Nano-tech pack in one boat next season to see how they hold up.

[detox]

I believe both Nano Tech and Thunder Powers come from same manufacturer.

[LuckyDuc]

While that MAY be true as most packs come from one or two overseas manufacturers. I do not believe that they are the same cells. These manufacturers have select product lines that they offer to certain distributors.

[detox]

But the name ThunderPower sounds cool and looks cool. So waht if they failed in this test.

I would like to see them try that same test against Hyperions.

[Jeepers]

just out of curiosity why do you guy's think it's not a fair test?

I have reasons of my own, but one would think this topic would have a lot more info being offered. than just "no"

[Punisher 67]

Just chiming in

[Rumdog]

why would it not be fair? I'd love to know.

[Chilli]

IMO its a fair test. But is it the definitive test?

Take 20 packs of each type and subject them to the same test. Then put fifty cycles through them and repeat the test.

See what the failure rate is and how long it takes to get a bad pack relaced.

Now thats a test!

[LuckyDuc]

why would it not be fair? I'd love to know.

That is what I asked in post #1. I'm not sure either.

However, with all things being equal, I'm not 100% convinced based on a sample size of 1 pack (3S 2250mAh pack). I would like to see some more testing... With Hyperions too!

Here's a picture of a 4-battery test I a while ago : (sorry for the crappy picture; couldn't get the EagleTree data in a file to post.)


Turnigy 30 C Turnigy 45/90 Nano Hyperion G3 TP 45/90 (all done with 5000 mah packs)

The whole deal is about how the batt's hold their voltage under load - remember a one volt drop equals a one KV drop at the prop.

After one year the first three are like air pillows; the TP's are a solid brick.

I'm not espousing any opinions here; just some data for discussion

Interesting reading : a visit to Thunderpower

While I would like to believe the test, I have to say I am somewhat sceptical, and this is coming from someone who only owns 65/130c nano's as well. Companies don't get a good reputation by being poor performers, and I can't fathom how there would be such a drastic difference between to 2 batteries in that test even tho I have a vested interest in wanting to. Simple answer is we will never know……

Tony that thunderpower tour was a great read thanks for posting but realisticaly a lot of young boaters absolutely cannot afford them - Wife , kids , bills , etc put a huge damper on the hobby budget . I can see a racer that pushes his cells to the ragged edge the thunderpowers being a great investment or the saws racer looking for every little bit of edge he can muster .

Peter, no doubt that "premium" batteries are somewhat overkill for sport boating. I use budget batteries for fun, but as of this year racing in my district (NAMBA 19) has grown substantially. The two SAWs in L.A. can be accomplished with a budget battery ( I used some GenAce packs at the last SAW) ; most any battery will hold it's nominal voltage when early in their use cycle so that's what I've been using. Also the spec class boats don't put a high demand on the pack(s) so my Spec boats normally use Turnigys or GenAces. For my full-bore P-Mono it's Thunderpower all the way and I'm going into my second season with my TP's in that class.

FWIW , besides my income from rcboatbuild, I have two other part-time jobs, at least half the proceeds of which go into a savings account for batteries at the beginning of each race season. You gotta work hard if you wanna play hard !

A few of us in SoCal FE have just made a bulk purchase of what we hope are high-performance packs from a Chinese supplier that look very promising. I'll disclose the results after they arrive and are put to the test

That would be coool Tony - thank you

what name is on them Tony?

[Drax21]

Hey Tony would you be talking about POWER PLUS batteries? I have heard of a massive factory in China who have recently in the past 6 months developed LIPO Batteries for RC which they believe rival the best.

[properchopper]

Power Plus Batteries can be obtained from Shenzhen Tianline Technology Company Ltd. in Guongdong, China. They are made up from Samsung cells. The ones I am getting are not these. I'll disclose more soon - be patient

[LarrysDrifter]

I havent done any testing between the two brands of packs, but ive have both and can say I wont be buying either again. The nanos always puffed and the Thunder Powers split the hard cases when they swelled and became about 3" thick. I use regular Turnigy packs and have had no problems with them.

I have only used regular Turnigy packs so far with no problems. I have used 1 Thunder Power 2s battery and it also swelled. I have a local dealer in the UK for Power Plus Batteries , has anyone tried them?

[detox]

Running packs down TOO low will cause anypack to puff. I try not to go more than 65% below rated capacity.

[srislash]

Just my 2 cents here.I'm running Sky's and a set of TP 5000's.After this season(not too many runs),the Sky's take alot longer to balance at the end of the charge.I bought a set of each at the same time so I could monitor and come to a conclusion as they age.

[sailr]

I have had much bettter luck with the regular turnigy packs and the Sky Lipos than the Nanotechs and Thunderpowers. However, that being said, HYPERION's are the ultimate packs that I own. More expensive but last three times longer at least and always balance out.

[Drax21]

Yeah, I never run my packs below 3.3V I always use Lipo Protectors.

[Brushless55]

I agree..
with FE boats I run them to 70-75% and my 3D planes I run them 75-80%

Yeah, I never run my packs below 3.3V I always use Lipo Protectors.

if that's resting volts, it's very possible you have run them beyond 90-95%
cuz that's only 6.6v for a 2s pack and 9.9v for a 3s pack

Thing is my Turnigy batteries are all fine, and a Seaking Esc is normally set to cut off at 3.3V.

thing is, if your lvc is set to 3.3v then your resting volts is higher
so most any packs would be just fine

[Drax21]

So what I get from this....is that my TP packs should not have swelled after about 15 cycles.
