Testing Lipo's Power Output, Turnigy & Parkzone C Ratings tested

[rogue277]

you neglected to mention that higher C rating comes at cost of more mass. why have capability for X watts wherr you only need max of 0.5x watts?

[nzRCreviews]

Why do people use prop motoers not edf fans!!??

[dhdsracer]

@nzRCreviews Props are almost always better. EDF's can be fun and they give you the look of jets but they are notoriously inefficient. Props give you far more instant thrust and less power consumption.

You are standing in the propellers' plane of rotation....

What it does show is that the internal resistance of the Nanotech is less than the others. You dont even state what the sustained voltage or power is, only the peek.

[carboyroy]

great real world test, need more of this type test.

Kudos to you sir

Hey, good review.

I just wanted to add that the test only tests using a motor that wants to pull around 240W, and varies based on the voltag

The nanotech hold's it's voltage a little better, which explains the 10W extra that the motor pulled, due to the higher voltage.

If you were to connect it to a system that actually tried pulling 100A, the nanotech would show it's ability to output 45C, the others would obviously fail, 20C, 25C...

The test wouldn't be fair to the other batteries.

МОТОР ? MOTOR?

Great vid and info! Thanks

I have 3 types of lipos for use. 2 in 2200 mah 3s and only the Nano in 2650 3s for my 3DHS Extra 300 SHP. I love the Nano batts.

[dhdsracer]

Yeah, those nano's are a rare breed. Put them in your wish list and they will email you when stock comes in.

[TheRattleSnake3145]

Thanks for this vid, most of my lipos are the Turnigy 40c.

Avery time I go to order more the nanotech's are out of stock!

[Brushlessboy16]

A different way of looking at this would be to stress the packs to what they are rated for. 2.2ah(20c)=44amps etc.. Then see how much voltage they can hold under different incremental loads on them.

Say you have the 2.2ah 20c pack. Measure how much voltage it holds at 11a, 22a,33a, and 44a.

I hope you can follow what im saying. Just that voltage drop under load is what we need to know. we want to go vertical without worrying about lipo cuttoff kicking in!

Keep up the good work :)

[dhdsracer]

@Brushlessboy16 You're right on about getting exact performance numbers. I was simply showing how the C rating will actually effect your performance. I am trying to walk the line between giving too much technical data that most can't follow it and dumbing down my videos. You're absolutely right about the proper testing for technical figures. These nano's are just a great deal and can keep the amps flowing under high stress better than others I have seen. Thanks for the comment!

[Brushlessboy16]

Hey don, very nice work in your videos.. I have one main concern.. your using the same load on each of the battery, its going to take the same (around the same) amount of power to do the same amount of work... Im no expert (Electrical engineer lol) but the only reason the nano tek's put out more wattage because they hold a higher voltage at a given amperage... This is a given since the pack's C rating is higher.

See next post

It seems like none of the batteries were pushed hard, did you have a chance to put a bigger prop on for the testing ? Great test anyway !

[dhdsracer]

@S9999Frank True, I was not trying to see how far these lipo's could be pushed. Just trying to see what resistance the battery's would give under "standard" loads. Excellent point though. Would you like me to be an extreme load test? Or any other requests for content?

[S9999Frank]

@dhdsracer

If you could test at 35-40 amps, you would still be within what these batteries are made to manage, at those loads I think you would see a lot more difference !

Anyway it would be interesting to see !

[dhdsracer]

@S9999Frank I'll do a quickie test on the 25C Turnigy VS the NanoTech at much higher loads. Looks like i'll be pulling out the monster inrunner and a 60Amp ESC for this one!

[dhdsracer]

@dhdsracer I didn't forget about this test. Just trying to find the time. More to come!

[S9999Frank]

@dhdsracer Testing at 35-40 amps would be interesting, still within spec, but would probably show much bigger difference !

[dhdsracer]

@S9999Frank I just put up the video you recommended. Take a look.

[therealheavyj]

i never even thought of jamming the ec3 into the xt60. Good stuff...

[dhdsracer]

@therealheavyj

hehe, yeah. The xt-60 is basically designed off the ec3. Both are simply 3.5mm bullet connectors in nylon, spaced the same. Funny stuff

[startazz]

As always man some great info there ;-)

[toyou999999999]

awesome vid man

[dhdsracer]

@toyou999999999 Thanks man! Let me know if you have any requests or thoughts on videos.
