my name is Ahmad Shamshiri and I am presenting this tutorial from Canada.
Hi! Welcome to a video tutorial from Robojax. In this video we are going to test this brand-new
lipo battery one to eight cell tester an alarm. had this one which can test and gives you the
alarm when the voltage dropped below certain points now the new model have come here this is
called BBX that's one to eight cell exactly the same thing but let's see what is the difference
and how we can use this and also I’m going to mention this one I have tons of batteries here
and I'm gonna test it and see how it displays and what is the difference both of these have
this button here on this one however the button is very tiny you just press it with your nail
this is easily pressed here so you can set the value at which this inform you because lipo
batteries have very sensitive characteristics so when the voltage drop below certain values
it will get permanently damaged so you can set your own values and when you fly your drone or run RC car or you
just a battery though when the voltage reduces this will make a buzz. so here at this point we
have connections so this is common and then this is for cell one two three and two cell
eight so we have nine pins here same thing here so that's ground and then it prints for itself
so this is a 3-cell battery now the 3-cell battery has four wires here for JST-XH connector here so
what you do is that you will on this side you see there are bumps the two these two on this
side it's flat so the ground wire is on this side and the that's the cell 1 cell 2 and cell
3 so you hold this and from left side this is the ground and that on that side goes so it's
a 3 cell and it shows all 12.2 number one for point zero nine number two for point zero seven
number three four point zero nine and again it just goes like that so when you fly your drone or run RC car
you connect this to the discharge or user to your system and this will be just hanging there so you
can attach this and it will have very loud bass sound. To set the voltage for a certain value to make
buzz, you press this button now it's three point three if I press it again it will go to zero in
for three point five so either you can make it off or two point seven and I say two point
eight so once you set it at two points eight the voltage of each cell now you see the first
cell is four point zero nine when it drops at 2.8V it reaches 2.8V or
below it makes big noise beep-beep-beep when you fly you're drawn from a long distances you can
hear it. now let's check this one so this is the same except that you have to know that you have
to insert it the same way the flat side should be up and you have to insert it on the left side
if you sert it on this side it will you will not be able to read because that's for cell 8
so now it shows third point two now it shows instead of number one it just shows two dashes
on this side so number three four point zero eight and then again so it goes all
so it shows the exact same thing but the buttons the pressing the button is easy now it doesn't
make buzz when you set it so with this one it was making buzz for 2.9 I set that now two point
nine after few seconds it returns back but this one when you change it makes beep. now I have this
collection of light for batteries this is ten thousand million per hour sixel and the result
three cell and I believe this one also I have this one this is for cell this is the result
this is for cell so I'm gonna test them one by one from that side and then let's see what we did here
with this and also we will do it with that one so that is for cell again flat side and that all
10.2 that's 2.9 so see one of the cell is low and that's how
it makes noise let's answer this one for cell all number one point three
point nine so access number two it beeped. let's check this battery
11.9 for the other one is three point nine three point nine so eleven point nine so no
bus same thing in here so now let's get this sex cell same thing flat side effects cell
all twenty two point four volts 3.7 3.7 three point seven four three point seven
three and number five three point eight four three point six one now let's answer this one
All twenty two point four volts and you can see each cell is displayed
that's a fully-charged 12.4 4.17 that's very high four point one three four point one six
third point for the phase also shows properly all the value let's check this one ten point
two that very low three point three five three point three seven and three point four nine so
if I set that at three point six three point five and let's see now a new blade battle because it's
below three point five let's do it this way this and let's set it at three point five all
ten the first one is the open three check the other one 12 point two so this is way above the
value is well not birth this is also very charged fully so to not make a buzz let's check this one
this is also fully charged 4.1 to 4.0 94.1 500 so let's check the voltage of the faithful number two
number one number two is four point one four point zero nine four point zero nine let's see what this
show that's number one and then number two four point zero nine so they are exact so thank you
for watching this for the test of lipo better with this casing and this was without the case
so one thing that I would prefer this one over this is that it has a little protection for the
damage but remember when the drone crashes I don't think any of these will survive so this
casing doesn't make much difference except it just uses always a little material and that's it so
thank you for watching please thumb up 👍 are also subscribe to get updates of my upcoming videos
