Best LiPo Batteries for Micro FPV Drones (1S, 2S, 3S, 4S | 300mAh to 1000mAh)

by Oscar

Here is a roundup of all the 1S, 2S, 3S, and 4S LiPo batteries I have tested for micro FPV drones, including toothpicks and whoops, with capacities ranging from 300mAh to 1000mAh. Performance (discharge capability) is determined by measuring voltage sag under constant load. I also measure the true capacity of each pack by discharging it slowly.

I keep adding new batteries to this database so you have a clear benchmark for finding the best batteries for your tiny whoops and ultralight micro quads.

If you are new to LiPo batteries, you should definitely check out my beginner’s tutorial on LiPos: https://oscarliang.com/lipo-battery-guide/.

Testing Methodology

To determine the best batteries, I focused on two key performance metrics:

  • Capacity: Measured by discharging batteries at a slow rate (e.g 1C) from full charge down to 3.3V per cell to accurately gauge their energy storage capabilities.
  • Voltage Sag: Assessed by discharging at a faster rate (e.g. 20C) from full charge to 3.3V to evaluate their performance under load throughout the discharge cycle.

C Rating

Every LiPo battery has a C rating printed on the label.

C-Rating is supposed to indicate the discharge performance of a LiPo battery. However, the numbers provided by manufacturers are often inflated for marketing purposes, and over the years they have become somewhat meaningless. This is why I am conducting these tests myself to find out how these batteries actually perform.

LiPo or LiHV?

LiHV is a different type of LiPo battery that allows charging up to 4.35V per cell instead of 4.20V. While standard LiPo is still mainstream for bigger quads like 5-inch and 7-inch, LiHV has become the standard battery type for micro quads because of the extra power it’s supposed to provide.

From my personal experience, LiHV does offer more power in the first half of the discharge cycle thanks to the higher voltage, but performance in the second half is similar to regular LiPo as the voltage continues to drop. Another benefit is that LiHV tends to have slightly higher energy density than typical LiPo, resulting in a slightly lighter pack for the same capacity.

However, there are concerns about the longevity of LiHV and whether it degrades faster than standard LiPo. I did some real-world testing to find out if this is true: https://oscarliang.com/lihv-battery/

If you use both LiPo and LiHV, make sure you select the correct battery type in your charger. Overcharging a normal LiPo to 4.35V per cell can be dangerous.

Testing in 2020

Here’s my testing from 2019-2020. Although some of these batteries might not be unavailable today, I thought it would be useful to keep these data for future reference.

Click these links will take you to the specs and product pages.

1S (2020)

Nitro Nectar 1S 250mAh HV

Product Page (GetFPV): https://oscarliang.com/product-69ys

Specs:

  • Price: $6
  • Size: 6.7×11.1×52.2 mm
  • Weight: 6.8g
  • “Claimed” C-Rating: 30C

Performance:

  • Max Discharge: 4/5
  • True Capacity: 254mAh
  • Value: 3/5

All three 1S batteries tested here seem to have pretty similar performance in terms of maximum discharging rate. However they are quite different when it comes to price and weight, so these become the main considerations.

The Nitro Nectar battery is made by NewBeeDrone, one of the smallest pack (at 250mah) you can find out there that provides decent amount of power.

BetaFPV 1S 300mAh HV

Product Page (Amazon): https://amzn.to/2roB1xD

Specs:

  • Price: $4
  • Size: 6.2×11.8×63.4 mm

Most 1S LiPo these days don’t have wires anymore, for the weight saving and lower resistance. But you might appreciate the “extended” battery connector in these GNB 1S batteries, as it makes plugging in slightly more flexible. And yet it’s lighter than the BetaFPV given the same capacity and performance. However it’s quite expensive.

Emax 1S 450mah HV

Product Page (GetFPV): http://bit.ly/34RY3ff

Specs:

  • Price: $8
  • Size: 7x18x59mm

  • True Capacity: 306mAh
  • Value: 5/5

I am surprised by how affordable this battery is given its high quality. It’s a very “punchy” pack with minimal sag throughout the entire discharge cycle. It’s also relatively lightweight compared to other packs with similar capacity and performance.

GNB 2S 350mAh 50C HV

Product Page (AliExpress): https://s.click.aliexpress.com/e/_DBXl9W5

Specs:

  • Price: $12.5

  • Battery Lead: 18AWG
  • “Claimed” C-Rating: 50C

Performance:

  • Max Discharge: 2/5
  • True Capacity: 310mAh
  • Value: 1/5

I’m puzzled as to why this pack is priced so high when its claimed C-rating and performance are lower than other superior packs from GNB.

GNB 2S 450mAh 80C HV

Product Pages:

Specs:

  • Price: $10
  • Size: 14x18x62mm
  • Weight: 28.6g
  • Battery Lead: 18AWG
  • “Claimed” C-Rating: 80C

Performance:

  • Max Discharge: 5/5
  • True Capacity: 460mAh
  • Value: 5/5

One of the best performers in the 2S LiPo testing, yet it’s a few grams lighter and only $10. This is my go-to 450mAh 2S if you’re cautious about less known brands like “XF Power.”

GNB 2S 520mAh 80C HV

Product Page (AliExpress): https://s.click.aliexpress.com/e/_DCqyEeD

Specs:

  • Price: $11
  • Size: 14x17x68mm
  • Weight: 29.1g
  • Battery Lead: 18AWG
  • “Claimed” C-Rating: 80C

Performance:

  • Max Discharge: 4/5
  • True Capacity: 500mAh
  • Value: 3/5

Despite being “80C” like the 450mAh from GNB, this battery shows more voltage sag towards the end of the pack. It’s slightly heavier than the 450mAh version, suggesting either a lower C-rating or capacity. The capacity test showed it’s about 20mAh short. I’d recommend sticking with the 450mAh version for those looking for flight time.

GNB 2S 300mAh HV (Gaoneng)

Product Page (AliExpress): https://s.click.aliexpress.com/e/_DciSBWd

Specs:

  • Price: $10
  • Size: 13.5x17x50mm

  • Battery Lead: 18AWG
  • “Claimed” C-Rating: 80C/160C

Performance:

  • Max Discharge: 5/5
  • True Capacity: 301mAh
  • Value: 5/5

Excellent performance in terms of voltage sag, and the real capacity lives up to the claim. Great battery!

URUAV 2S 300mAh HV

Product Page >> http://bit.ly/2KdLWkN <<

Specs:

  • Price: $9
  • Size: 13.5x17x50mm
  • Weight: 22.7g
  • Battery Lead: 16AWG
  • “Claimed” C-Rating: 80C/160C

Performance:

  • Max Discharge: 3/5
  • True Capacity: 270mAh
  • Value: 4/5

It has specs similar to the GNB 2S 300mAh HV 80C, except it’s nearly 3 grams heavier, likely due to the larger gauge wires. However, voltage sag is slightly worse than GNB, and with only a $1 price difference, I’d probably choose GNB for batteries of this size.

GNB 2S 350mAh (Gaoneng)

Product Page (AliExpress): https://s.click.aliexpress.com/e/_DkUwbRB

Specs:

  • Price: $10
  • Size: 13x18x52mm
  • Weight: 21.7g
  • Battery Lead: 18AWG
  • “Claimed” C-Rating: 35C/70C

Performance:

  • Max Discharge: 1/5
  • True Capacity: 368mAh
  • Value: 1/5

I’ve tested quite a few GNB batteries, most have been great except this one. Voltage sag was simply awful, can’t even sustain a full throttle punch-out for more than a few seconds. Battery gets very hot too. DO NOT Recommend.

NewBeeDrone 2S 350mAh

Product Page (NBD): https://oscarliang.com/product-uk8f

Specs:

  • Price: $14
  • Size: 49x17x25mm
  • Weight: 24.5g
  • Battery Lead: 16AWG
  • “Claimed” C-Rating: 60C/120C

Performance:

  • Max Discharge: 3/5
  • True Capacity: 310
  • Value: 2/5

Pretty good quality battery, but a bit more pricey than the rest. Could have used 18AWG wires instead of 16AWG to save a gram or two, without noticeably impacting performance.

XF Power 2S 450mAh

Product Page: >> http://bit.ly/2OzR8n9 <<

Specs:

  • Price: $9
  • Size: 14x18x60mm
  • Weight: 33g
  • Battery Lead: 16AWG
  • “Claimed” C-Rating: 75C/150C

Performance:

  • Max Discharge: 5/5
  • True Capacity: 475mAh
  • Value: 5/5

This has to be one of the best value 2S 450mAh I’ve tested so far. It’s a slightly bigger battery than what it claims to be, maybe that’s why the discharge rate is surprisingly high. It’s only $9 and it comes with a balance lead protector. Mind you this is heavier than other ordinary 450mAh pack.

Crazypony 2S 450mAh

Specs:

  • Price: $11
  • Size: 18.5×13.5x60mm
  • Weight: 27.4g
  • Battery Lead: 18AWG
  • “Claimed” C-Rating: 80C/160C

Performance:

  • Max Discharge: 1/5
  • True Capacity: 427
  • Value: 1/5

Absolutely terrible performance, avoid at all cost. Maximum discharge rate is low, and battery gets very hot. I bought four, two of which have swollen cells out of the box.

GNB 2S 650mAh (Gaoneng)

Product Page (AliExpress): https://s.click.aliexpress.com/e/_DkA58pP

Specs:

  • Price: $13
  • Size: 16x18x62mm
  • Weight: 31.4g
  • Battery Lead: 18AWG
  • “Claimed” C-Rating: 60C/120C

Performance:

  • Max Discharge: 5/5
  • True Capacity: 620mAh
  • Value: 5/5

Excellent battery! Recommend!

  • “Claimed” C-Rating: 50C

Performance:

  • Max Discharge: 3/5
  • True Capacity: 334mAh
  • Value: 2/5

Being 1 gram lighter than the GNB 300mAh 80C, the voltage sag is a lot worse. That clearly shows that batteries with higher discharge rate do weigh more.

GNB 3S 450mAh 80C HV

Product Page (AliExpress): https://s.click.aliexpress.com/e/_Dl8hcsl

Specs:

  • Price: $12
  • Size: 17x21x64mm

Amazing performance! Probably the best 3S 300mAh battery I’ve tested so far. Highly recommended. Voltage sag is minimal, I guess it’s 3 grams heavier than other 300mah packs for a reason :)

URUAV 3S 300mAh HV

Specs:

  • Price: $10
  • Size: 11x18x65mm
  • Weight: 29g
  • Battery Lead: 16AWG

That damn Lava magic… How are they doing this?!

Hello again. With the claims of the NX69 connector being better than the BT2.0 it would have been interesting to see a comparison for 300mah batteries that favored the NX69 a bit more (NewBeeDrone claim they handle larger loads better). A 12A continuous load would simulate high end whoop racing much better than 6A. If the LAVA IIs still comes out on top we can hopefully lay the NX69 to rest. Sorry for suggesting you do more work for us, your battery testing is really good as it is.

The performance difference between NX69 and BT2.0 is not huge; the more important question is how accessible compatible batteries are. A “larger load” is outside the scope of my testing, as my intended application is 65 mm and 75 mm tiny whoops, which typically draw less than 4 A on average during a normal flight (you can verify your current draw in the OSD if your setup includes a current sensor).

Even with higher loads, you would see similar graphs, the voltage sag is just gonna be more exaggerated. Anyway this isn’t particularly meaningful in practice, since tiny whoops are not especially power-hungry.

There’s plenty of racegow 5 footage out and the amp draw of the top pilots is pretty high, it seems 12A continuous is fairly normal:

I agree with what you’re saying about accessibility – I don’t feel like marrying myself off to NewBeeDrone and only use their batteries for all eternity. But I’m still curious if their connector really is that much better under higher load.

1S battery test 2025: The 300mah NBD battery with the NX69 connector is listed as having a capacity of 345mah. On the graph it shows as having much less, lower than the BetaFPV Lava II which is listed as having 323mah capacity (which is more in tune with the graph).
Is there a typo somewhere or some other reason for this discrepancy?

Reply
Oscar 12th December 2025 - 12:01 pm

Max capacity is measured by discharging slowly at 0.5C, while the graph in this post is based on a much heavier 20C discharge. As a result, significant voltage sag is expected, causing the test to end before the pack is fully discharged. High C rating battery will be able to discharge more under heavy load before voltage sag gets really bad. Additionally, some energy is lost as heat at such a high discharge rate.

GNB 530 2s LiHV 90c batteries XT30 plug fit my Mobula 8 perfectly but out of eight batteries (3 pack from amazon and 5 pack from Bangood) 3 cause unexplainable full throttle flyaways, which is repeatable, and cannot be used. The other five fly normally. The three “cursed” packs work fine in my 3″ toothpick though, very odd.

hi i just wanted to ask if i can run a 3s on T-motor velox v3.0 1950kv motor
the battery is molicel P42A 4200mah 11c (45amps)
or i thought ill run 3s2p cause itll give 90amp discharge with 12.8v
each battery weighs about 80 grams so 3s2p will be 480 grams and a 3s with 45 amp will be 240 grams
how shall i proceed with the battery
i am asking all these questions because T-motor velox v3.0 1950kv motor has a max amp rating of 45Amp . 4 motors will draw about 180amps in total which the battery can provide even with 3s3p config
i have only 9 batteries with me and i cant afford to get more also itll be around 750 grams just the battery without the quad . with the quad itll be around 1KG can my motor lift 1KG . idk help pls

Hi, did you look at the GNB 530mAh 2S? It is a new cell composition or the same 550mAh rebranded?
Thank you

Yes I do plan to test more batteries for micros. I need to make a list first because there are so many of them nowadays.

I wish to have battery life expectancy test (by month) instead of initial quality test. I saw some people said GNB battery capacity drop dramatically after one month of use compare to other brand.

Hi Oscar ,
Love your work – thanks !!!
Can you review the new : Gaoneng GNB 660mAh 3.8V 1S 90C/180C HV 4.35V Light Weight Lipo Battery PH2.0 ?

Oscar, could you do a comparison of the GNB 600mAh 4S 90C LiHV Battery and the GNB 650mAh 4S 80C LiPo Battery please, as the capacity has only 50mah difference but the weight is 56g compared to 80g.

I use 4S 650mah for my 95X V3, no problem at all.

Has anything significant changed in this article in the last 8 months? Could you test the GNB 1S 650’s?

I just tested 4X CrazyPony 1S 550mah (each used about 10 times) using my West Mountain Radio battery analyzer. 2 out of 4 failed (80% capacity at 2C discharge).

Like I said in the review, avoid anything with the name Crazypony on it.

Oscar,

Please test and post results for the Tattu 4s450 mAh lipos. In my experience so fair they seriously under perform. Alot of voltage sag under moderate to high throttle. I have been working with a US vendor who has sent me 6 packs already and its the same result….super high IR as reported on my ICharger 406 Duo.

slawur 25th November 2019 - 9:55 pm

Oscar, did you charge HV batteries to 4.35 or to 4.20? It’s important for me since I’d like to buy HV and charge to 4.20V because I have no more options locally and I’m curious if those will have true capacity when charged to 4.20v OR its better to wait for normal non-hv batteries. Thanks!

Reply
Oscar 1st December 2019 - 4:30 pm

I charge HV battery to 4.35V. Normal Lipo to 4.20V before testing.

Oscar – I would love to see this test expanded to include 3S, 700, 750, and 850 mAh batteries. The TransTEC Beetle for DJI HD FPV is basically a 2.5″ HD FPV whoop, recommended battery is a 3S 750 mAh battery. Can’t find much testing on this size of battery and as you know, C ratings are a joke. I would love to see the:

Tattu R-Line 11.1V 3S 700mAh 95C LiPo Micro Battery – XT30
Tattu R-Line 11.1V 3S 750mAh 95C LiPo Micro Battery – XT30
Tattu 11.1V 3S 850mAh 75C LiPo FPV Battery – XT60
Tattu 11.1V 3S 850mAh 75C LiPo Micro Battery – XT30
GAONENG GNB 3S 750mAh LiPo Battery 11.1v XT30
GAONENG GNB 3S LiPo 850mAh 11.1v 80C XT30
RDQ Series 11.1V 3S 850mAh 75C LiPo Micro Battery – XT30

And any other such sized 3S battery. Thank you!!!

Oscar – the “GNB 2S 650mAh (Gaoneng)” can’t possibly 8mm thick right? I see you copied the dimensions from banggood, but this seems wrong.. should it be 18mm instead?

Reply

Yea it’s a mistake from the product page, dimension should be 16x18x62mm

A lot of people are curious about the GNB 520 vs the GNB 450 (which you’ve already tested). I’ve heard some mixed results between the two, even though both are 80C & LiHV by the same company…

I can tell you RDQ are bad batteries. I have better flight time with 450mah GNB then 525mah RDQ. Well all my 450mah are better then my 525!!

I recommend GNB and Pulse. Tattu are average but for same price I recommend GNB.

@Taylor A Jenkins….I have the same question. I use RDQ 2s and 3s 350mah lipos mostly. I also have some GNB 300 3s. I usually prefer GNB, but my RDQ lipos perform better!? I’ve read people say RDQ were GNB rebrands…so that confused me. Would love to see tests results of “pros”…
