RC Day: LIPO Comparison - Turnigy vs Turnigy nano-tech

[@flightmonkey4225]

Price, matters when you're on a budget. I just fun fly, so regular Turnigy is my lipo of choice. 😎

[@hairlesshippy]

I think it shows that both batteries have the same watt and amp draw but the higher C rated battery may have a little more sustained power during times of high consumption. I wouldn't say nothing. Thanks for posting!

[@jbx907]

nice video demo,actually people are mislead by heaving high c it would discharge more faster. its not the case, discharging depends on loads, if you didn't change your load (motor) it will discharge the same, the only difference with higher c is, it can handle more discharge current keeping the lipo voltage steady and temp less. double C or 20 > 40 means it can handle twice discharge current than the later, this would happen of you change the motor (load), btw i was w8ing for the maiden FPV

My friend and I fly every day during lunch break. My friend's Nano techs are puffy but mine have never puffed out. The only thing I do different than him is that I charge at a lower rate. My 2200's I only charge at 1 amp, he charges at 2 amps. I don't think he discharges his any more than I do either. I really like the nano tech.

[@PilatusPorterPC6]

Maybe my friend is running his batteries too far down and/or run too hard? Don't know why his batteries swell and mine do not?

[@rotagen5]

I think it may be a general phenomenon. I have seen the same thing from other brands, the same mAH battery with a higher C rating performs poorly and lasts about half as long in storage. I have had batteries bought on same day, same number of cycles and the lower C-rated battery always outperforms the higher C, as in faster plane and higher watts.

[@ksrnate]

20% ?

[@G56AG]

To make a test mean anything it needs documentation, for example for top speed you run a timed course, ideally a straight line speed test is best since corners can introduce variables, 'it feels faster' isn't a valid test. Using the test you used, it would be slightly more valid if the pilot didn't know which battery he was flying.

[@harrisontashjian752]

To be fair testing the amps is not good, motors only draw the amps they need, not how much the battery can output

[@kdanagger6894]

The standard Turnigy voltage sagged less and provided more amps and watts in the static test. That means the standard Turnigy has lower internal resistance, will generate less heat and is quite frankly a better battery. At least in this case. End of story.

[@peterrobinson4820]

I bought two nano-tech 2200 7.4v lipos recently. Just sitting in my workshop one has swelled the other is ok so far. I take care of my batteries and run well under the c rating and charge correctly ( I am a trained C&G radio and TV engineer) These things are crap. Seems to me that the lipo market is a lottery though. I have cheap lipos which are first class after several years of use. I am about to purchase more lipos . From what I have experienced and seen in use I may well go for Overlander.

[@flightmonkey4225]

I think for $11 Turnigy, is a great battery. Since you stay within the C ratings, it should fit the bill. I run regular Tunigy lipos. I smash them in crashes before 2 year period. $20 and up lipo brand's are just not worth it for me. Just give rhem a try. Hope rhis helps.

[@eastcoast78]

Nanos are decent, but they are more keen to puff at a lower V threshold. So don't drain em to much. Ive drained my 20-30c turigy's closer to LVC a lot and not one has puffed. The lower C rated batt pulled more amps then the nano as well. 205W nano 203W? i know its not much, but for a battery thats twice the Price i would expect at least 240w I think the nanos are over rated! thanks for the vid hairless

[@overip]

nice video!!!! :)

[@mareksvrcina5279]

I don't think that it actually can make a difference. Such extreme C rating at these relatively large capacities is not of any use, as the first battery is already capable of continuesly supplying more amps than the small motor in the plane can actually consume. It likely even can't draw this much during short periods of time. Though it might come in handy when using small batteries in quadcopters and other multi-propeller devices where the current draw is really high compared to the battery's tiny capacity.

[@puchomoreno]

The C rate has nothing to do with the amps drawed. The amps depend onf the load, and motor. You only need high Cs when you are going to have a lot of amps being discharged. And if you want longer flight times, you need batteries with bigger capacity..

[@1981therealfury]

I love it when people state the blatantly wrong as fact. for anyone else reading this, the above post is totally false. C rating is the rate of how fast a battery can discharge, a 2200mah battery with a 10c rating can be discharged at 22amps to empty in 6 minutes time. 1C means it will take an hour to discharge, 60c means it will discharge in 1 minute. AH (x) C-rating = Max amp draw. 2.2 (x) 10 = 22.

[@Nubyrc]

look amp draw is c raiting do not let anyone try to sell you a battery telling you anything different. If you ESC and motor draw 20 amps, then get a 30 c lipo and have some to spare, you see the amp draw will go up as the parts get warm, oh yea they forgot to mention that, plus bigger props or added weight to plane amps go up, to be safe get a lipo at least 10c higher then amp draw of your set up. And it doesnt have to be a "nano tech"

[@TheLukey21]

The nano tech felt faster even though it pulled less amps, I think it might all be in your head

[@hairlesshippy]

LOL.. yea.. I think you're right!

[@MrEatherbunny]

Hairless Hippy Maybe a bit more credible if the pilot was "Blinded" to what battery was in the plane.

[@neodimicri]

Italian?

[@niklaswallin9478]

?! I charge my nano 2200 @ 6A.. 1amp is very low.. ..3-4amps would be quite safe

[@wayneshephard]

Come on guys, know your electrical theory before making claims such as these, you just leave yourself open to criticism, I can see what you were trying to do but not when your load is less than what either battery can easily deliver, no difference! Placebo maybe..

[@hairlesshippy]

Thanks for your criticism. Sounds like you know much more than I do about electrical theory. Good job!

[@wayneshephard]

Your video would be relevant if you had a load greater than the first battery so the second one could actually rise to the challenge, I can see what you're trying to do. Current delivery is determined by the load but also the capacity of the source to manage that load. At both times you appear to have 17 odd amps flowing so the plane should perform the same, unless the second battery was slightly lighter. We all learn from each other mate and believe me I am still learning, I'm reading up on FPV and relying on people like yourself to see what I can find out before I shell out the dollars. Happy flying :)

[@marshalcraft]

Wayne Shephard it's called puekert's law. basicaly the higher the current the less capacity the battery has and i dont mean it will drain faster just because of more amps= volts go down faster, but the battery is less efficient at high amps than low. so a battery say could deliver 2500mA for 20 hours but at 90 A it might last 2 minutes. the curve is not linear a battery uses it's actual charge better with lower amp draws but with high draws, alot of charge is waisted so that the time it should last is actually less than you would calculate just assuming it's voltage and current and capacity.

[@marshalcraft]

marshalcraft also as claimed the nano should be better cause it has a higher C rating but turnigy might be pulling a fast one on us.

[@MrEatherbunny]

Yep, spot on Wayne.

[@Nubyrc]

well 17.5 amp for a 20 c is nothin try 40 amp with a 20 c and see what happens to lipo!

[@Hells_Gate]

I got nano's. not that impressed with them. The normal turnigy batts are better. Just not as higher charge current if you are in a hurry. Boo to nano's
