Good day! Today we're gonna take a look at a relatively new brand of LiPo battery, Auline.
Specifically, I'm going to compare the Auline 4S 1000 mah 60C Micro FPV drone battery with
the GNB 4S 1100 Mah LiPo to see how it stacks up. Both of these are lightweight high-capacity Micro
FPV drone batteries good for extended, endurance, or long-range flights with your Micro FPV drone.
Neither of these, with their C-Ratings, are designed for high-performance, max thrust flights.
They're more for just cruisin' around! I'll look at the physical characteristics,
check internal resistance, and show you the results of my extended flight "fly-off"
between the two. Let's see if the Auline challenger can actually compete
with the well-known GNB champion as a Micro FPV drone battery for extended flights!

All right, first of all let's go ahead and take a
look at both of their physical dimensions and weights. The Auline 1000 comes in at
about 63 point . . . about 64 millimeters long by 38 by 18. Whereas the GNB
comes in at
59 by about 33 and a half 34 by 25.6. All right let's weigh them in. Tthe GNB weighs in at
91.2 grams and the Auline comes in at 83 point . . . about 83.2 grams. So there's about an eight
gram difference between the Auline and the GNB all on being eight grams lighter. So, based on that,
remember last video I showed you on my website one of the factors I look at
before purchasing a battery is its capacity to weight ratio. Here we see that both of these
micro FPV drone batteries are very similar in that regard. So if we can get approximately
the same flight time on the Auline that we do with the GNB while saving eight grams of weight
and both at about the same price point I may be switching over to the Auline 4S 1000 for my
extended flight times with a micro FPV drone weighing in at 0.55 pounds or less (which is
under 250 grams). All right let's take a look at their internal resistances. First of all
both of these are brand new batteries. Neither one has ever been used and this
is the first time I'm charging each of them. I'll be using my Hobbymate D6 Dual Lite Smart Charger.
We can see the time up here that each one of them are charging so we'll wait just a couple minutes
and then we'll check the internal resistance which will show up down here
after I use the scroll wheel. All right let's take a look at the internal
resistance of both of these LiPos after about two and a half minutes.
On channel one our Auline 4S 1000 has an internal resistance of probably about . . . lowest is 50
on a cell, highest about 65. So I'm going to guess probably around between 55 and 60.
Then on our channel 2, our GNB 4S 1100
has a much lower internal resistance of about . . . I'm going to say around 18.
So you can see the IR on the Auline4S 1000 is higher than that of the GNB 4S 1100.
This actually should be a little bit lower since it's got a higher capacity but I'm not sure it
should be that much lower. Now when you measure the IR of your new micro FPV drone batteries,
remember to record it somewhere so that you have it as a reference number for future measurements.
You can write it on the LiPo with a sharpie pen or, as I demonstrated in this video
on the D6 Dual Lite charger, I use a LiPo battery management excel spreadsheet which I'll place
the template for you to download in the video description below. All right here we are coming
close to the end of the charging cycle and we'll take a look at the internal resistances again see
if they've changed at all. On the Auline 4S 1000 (channel one) it looks like they have dropped down
to about I'm guessing around 45 maybe and on the GNB 4S 1100 they're still much lower
probably around 13. So the Auline still does have a higher internal resistance than the GNB.
That may say something about the longevity of the Auline over time we'll just have to see. Okay,
before we go any further I found it a little bit interesting that the internal resistance
of the Auline was that much higher than the GNB. So I went ahead and did some further testing to
make sure it wasn't a one-off based on either of these specific batteries. So I tested three more
brand new Auline 4S 1000 milliamp hour LiPos and recorded their internal resistances two minutes
into charging and at charging completion. I didn't have any more new GNB 4S 100 milliamp hour LiPos
to test so I compared the last new Auline I had with a slightly used GNB using the same charger
and methodology. I've recorded all my results in this table and just to summarize the results I
obtained with this methodology, the Auline 4S 1000 milliamp hour LiPos had an internal resistance
between two to three times greater than the GNB 1100 milliamp hour LiPos. As I mentioned earlier,
I'd expect the 1000 milliamp hour Auline's internal resistance to be a bit higher than
the GNB's simply because its capacity is lower. However, I have much lower capacity GNB 4S LiPos
that also have a lower internal resistance than these Aulines. So, what does this mean?
Well, honestly at this point, I don't know. It may indicate we'll get fewer cycles out of the Auline
over an extended period of use than we do the GNB's. Or, perhaps they'll last just as long. Even
if they do end up having a shorter life span, the question then is "how much shorter?". When you're
talking about the average lifespan of a LiPo being on the order of a few hundred cycles, possibly
lasting two to three years, perhaps a lifespan that's ten percent less yet the battery weighing
eight grams less might be worth using it for your micro FPV drone flight battery. All right let's go
ahead and continue with our testing and check out the Auline's flight time performance against the
GNBs which is what we all should be interested in. All right, now that we have the capacity to weight
ratios, the internal resistances of both batteries and they've both been fully charged,
let's see if the Auline 4S 1000 micro FPV drone battery can hold its own with respect to the
flight time against the GNB 4S 1100 milliamp hour battery. Keep in consideration the Auline at about
83 grams is about 8 grams lighter than the GNB so that could make a difference with regards to
registering your drone and later on requiring remote ID. Of course this is one flight and in
this video I'm not taking into consideration the life span of either of these micro FPV
drone batteries. That's something that we'll have to take a look at over a period of time.
Since these are going to be long flights, I'm just going to show you the start and end. Here we go!
Okay, those were some interesting results! I was not expecting that. I could think of a few
more words to describe it – surprising, shocking, ridiculous, unbelievable.
I thought so too so I redid the exact same test using another brand new Auline against a used GNB.
I wish I could tell you I got different outcomes. I did not. I got nearly identical results! Maybe I
saved you a few bucks here today. Thanks for your time. I'll see you next video. Clear skies friend!
