hi there everyone and welcome back to

the channel today we're going to be

testing some batteries from beta fpv

these are 1s lithium High volt packs

designed for tiny whoops and we're going

to be looking at the new lava series

their 260 Milah 300 Mah and 550 Milah

packs we're going to be testing them all

on the battery tester and we're going to

be looking at both the variation pack

to- pack and also how these batteries

stack up against all of the other 1s

tiny woop packs that I've tested it's a

lot to cover in one video let's not

waste any more time let's dive right

into it if you're interested in product

recommendations backed by scientific

testing then please check out the links

down in the video description to my

website AOS rc.com there you'll find

recommendations for props Motors

batteries Electronics everything that

you could want for your fpv drone to

make sure that you get the best

performance and the best possible flight

experience don't waste your money check

out those links and if you want access

to my full database of product testing

results then all of that is available on

my patreon and there's a link down in

the video description for that as well

please check those out I'd really

appreciate it to test these tiny mop

batteries we need a little battery

analyzer so this is my West Mountain

radio CBA battery analyzer and I can

take a tiny mot battery like this plug

it in and I can do a programmed

discharge so we can test various

different aspects of the battery with

both a constant power discharge which is

kind of the standard test for batteries

and also a burst discharge test as well

the first test we're going to look at is

a constant power discharge test so we're

going to start the pack at fully charged

4.35 volts and discharge it all the way

down to fully empty at 3.1 volts and we

could discharge lower than this but I

use 3.1 volts as the low cutof voltage

for all of my battery discharge

testing we discharge the pack at

constant power so we calculate That

Power by taking the nominal voltage of

the cell which is 3.8 Volts for these

lithium High volt packs multiplying that

by the capacity of the pack in amp hour

which is 0.3 for a 300 Milah pack and

then multiplying that by 15 because this

is a 15 C constant power discharge test

that gives us the power that the battery

has to deliver during the discharge

which is 17.1 wats and obviously as you

would expect at 15c the battery

discharge takes just about 4 minutes the

second test we're going to look at is

the burst test and this starts off quite

similarly to the constant power

discharge test again we're starting off

with the battery fully charged and we're

discharging it at 15 C but this time

it's constant current not constant power

so we're discharging it at 15 times its

capacity in amp hours in amps so for a

300 milliamp battery that's going to be

4.5 amps we discharge for 48 seconds and

48 seconds at a 15c discharge rate is

going to take the batter battery down to

exactly 80% full at that point we start

ramping the current that we demand from

the battery and we ramp it until the

voltage of the cell Falls below 3 volts

and then we stop the test this gives us

a really good measure of how much power

the battery can deliver from 80% full at

its sort of Maximum possible discharge

current before the voltage Falls below 3

Vols per cell and by doing this

consistently for all the batteries it

gives us a really good comparison

between different batteries as to how

much performance they're going to give

you if you push them really really hard

let's dive into the data now and start

by taking a look at the 260 milliamp

packs under a constant power discharge

test and I tested five different

batteries so we've got five different

curves here and the curves are all

pretty consistent which is nice to see

there's not a huge amount of variability

between different batteries of the same

design and it's also really good to see

that all five of these packs delivered

more than their rated 260 Mah of

capacity under a 15c discharge test and

this is really very unusual because when

batteries are rated they're typically

discharged very slowly 0.1c is a typical

discharge rate and that means that you

get a bit more capacity out of them when

you're discharging much faster at 15c

which is typical of what we do in an fpv

flight the batteries normally don't

deliver as much capacity and so you'd

expect them to only to deliver 90 to

maybe 95 % of their rated capacity but

all the batteries in this case delivered

more than 260 milahs and that's really

nice to see if we move on to look at the

300 milliamp packs again all five packs

that I tested very consistent with each

other and again all of them delivering

more than their 300 Milah rating in the

15c discharge test which is really great

to see when we look at the 550 mli

batteries it's a similar story all I

tested four of these and they're all

very consistent again and these 550

milliamp packs really delivered quite a

lot more than their rated capacity I

mean they all delivered nearly 600

milliamp hours and at this stage I

wonder if beta fpv you know could have

maybe given these a bit of a higher

rating because I would have been quite

impressed if these were 600 Milah packs

rather than 550 but um yeah you're

getting more than the rated capacity out

of these batteries even under a very

fast 15c discharge looking now at the

data for the burst testing here's the

results of the 260 mamp packs all five

of them under the burst test again we're

doing a constant current discharge to

80% full and then ramping the power up

and we can see how consistently all

these packs perform there is nothing to

choose between them all the way up this

ramp and it shows that under this burst

test the performance is very very

consistent across all of the five

batteries that I tested and this

consistency is really really good to see

they Peak at 13.26 amps at 3.1 volts per

cell which is really very impressive for

such a small 260 mAh battery and that's

a 51c rating um under the way that I

determine C ratings I have to be clear

my C rating is not the same as the

manufacturer C rating but my C rating is

comparable across all the different

packs that I test looking at the 300

Milah packs now we can see again a

similar story to the 260 Mah pack the

batteries are all very consistent and

there's not much to choose between them

on the uh Power Ramp we do see perhaps a

little bit more variability than what we

saw in the 260 mlia packs but still very

very little we have to note that the

maximum power output about 45 watts is

almost identical to the 260 Mah packs so

even though the battery is bigger um

you're not getting any more maximum

power out of it the measured C rating is

therefore a little bit lower due to the

larger battery capacity so we're

dividing effectively the same current by

a slightly larger capacity and that

gives us a c rating of 45 C rather than

the 51 that we got for the 260 milliamp

packs and this is actually reflected in

the manufacturer C rating as well the

260 milliamp packs get an 80c rating and

these 300 Mah packs get a 75c rating

when we look at the 550 Mah pack packs

during the burst test again we see great

consistency between the four packs that

I tested and there's not much to split

them as we go up this ramp maximum power

output is about 1.8 times greater than

what we got out of the 260 millia packs

but the capacity is 2.11 times greater

so again the C rating is a little bit

lower on these 550 Milah packs compared

to the 260 and we're getting a measured

C rating of 44 C under my test

conditions and again just to reiterate

this is not the same as the

manufacturer's test conditions now we

have to take a look at how these

batteries compare against some other

options from different manufacturers and

we're going to start by looking at

energy density this is a measure of the

amount of energy that's stored in the

battery in W hours divided by the weight

of the battery in grams so it's a really

good measure of how much flight time a

battery is going to give you we can see

that the beta fpv lava 550 Mah it's a

big battery and it's got fantastic

energy density so it's going to be ideal

for really long flight times and it does

really well on this metric it's better

than any other 1S Battery that I've

tested for energy density when we're

looking at the smaller packs the 260 and

the 300 Milah beta fpv lava we can see

that the 260 Mah does a little bit

better than the 300 but both of these

batteries are doing really well in terms

of energy density and they're sort of in

that top tier and it's what we would

expect because these are of course

folded cell batteries and that

technology is known to be superior than

wound cells in terms of overall

performance for our tiny whoops if

you're wondering what the difference

between a folded and a wound cell is I

have a fantastic video where I cut apart

a bunch of different tiny batteries

to show you how they're constructed

inside I'll put a link to that down in

the video description if we look at C

rating now and obviously this is not

equivalent to the manufacturer C rating

but it is comparable across the packs we

can see that the beta fpv lava 260 mamp

is right up there over 50c and it's very

very similar to the very best packs I've

tested before from the likes of Doom um

newbie drone and gmbb those very very

high cated packs and the beta fpv lava

is right up there and not surprising

that folded cell technology is working

hard the 300 Milah and the 550 milliamp

don't do quite as well as the 260 in

terms C rating because although they

deliver similar or even more power they

are larger capacity packs and so we have

to divide the current that they deliver

by that larger capacity and that reduces

the C rating but that c rating is still

pretty respectable when compared to um

other options from gmbb and sub 250 in

similar sizes so these are still you

know modern contemporary packs and they

have good performance in terms of C

rating let's look now at at Power

density this is a measure of the amount

of power that we can get from the pack

when it's 80% full divided by the weight

of the battery and this is a really good

metric for determining how fast your

quad is going to be able to accelerate

what its top speed is going to be

because obviously you are taking into

account the weight of the battery so a

lightweight pack that can deliver a lot

of power is going to make the quad move

faster accelerate more quickly than a

similarly powerful pack that weighs a

lot more again the 260 milliamp power

pack is doing really well here in terms

of power density and because this is

also a very lightweight pack it's only

7.1 G or so it's a great pack if you're

looking for relatively short flight time

but um for a tiny Loop that has a lot of

maneuverability and a lot of top speed

because you're keeping that weight

really low that power density is very

similar to the Doom 320 and the newone

nitron to gold and these packs are the

best I've ever tested so it's right up

there in the top tier

then we drop down a little bit to the

550 Mah beta fpv lava again power

density of this is doing really well

it's better than um a similar size pack

from sub 250 and it's trading blows with

the tattoo rline 300 milliamp also a

folded cell and this g&b 300 milliamp

which um isn't a folded cell but it's

one of the best performing wound cells

I've ever tested so having looked at all

of the test data it's time for me to

decide whether or not to recommend these

beta fpv lava 1s batteries to you and

looking at the 260 and 300 Mah packs

first they are very nearly as good in

terms of performance as the NewBo nitron

to gold and the Doom 320 Mah they are

not quite as good as these top

performers but they're getting up there

they're getting pretty close and they're

using the folded cell technology that we

know to be really Superior for tiny woop

packs but I think the most important

factor here is the price the performance

is very nearly as good but the 260 and

300 milliamp packs are priced anywhere

from 20 to 30% less than the equivalent

packs from newbie drone or dogc per

battery so sometimes the pack sizes vary

but per battery they're between 20 and

30% cheaper and that's a big price

difference and if I know that price and

availability are going to change

depending on where you are and what

shops you're you're buying from but if

you can get those batteries at that 20

to 30% cheaper price the performance is

very nearly as good and unless you're a

racer who is absolutely focused on

getting the maximum performance

regardless of cost then uh that value is

definitely going to be something that

you're going to want to think about when

it comes to the 550 Milah packs um the

pricing there is actually more similar

to other options but the performance is

really really good that 550 Milah pack

delivers performance that's more similar

to like a 600 mamp pack so again the

price if the price is good and the

availability is good where you are then

I think you can confidently pick that

550 Mah lava 1s as a good option as well

hopefully that's helped you make your

buying decision there are links down in

the video description to where you can

pick up all these batteries today and

some of them are affiliate links which

means that if you happen to use them

click through you can buy the battery

you won't pay anymore but you will help

support the channel a little bit of uh

the profit that the retailer would

otherwise make comes to me and that

helps support the channel you don't pay

anymore it's a win-win for all of us so

if you can I'd really appreciate it if

you'd use those links that's all I have
