how long it takes to charge the battery that it's completely dead
this battery is dead so I'm gonna show you how to check the voltage of the
battery and itself separate if you want to measure the voltage of your left so
you take your plus and put that in the first connector so I fear the worst for
this battery sucks to be me though well now let's turn on the timer and
time how long it takes to charge the battery hello welcome everybody to a new
episode of DJI Mavic mini battery test we were going to see how long it takes
to charge the batteries that is completely dead at zero percent
is even not even light coming up it's completely dead down in the last flight
battery test we checked the lifetime how long we
could hover in one spot in mode C and shooting video in 1080p and we stretched
the flight time in real life up to 24 minutes but we depleted the battery from
its battery juice completely I'm sticking it in the charging hub there is also
not one single light coming up even when I press on this battery is dead so I'm
going to show you how to check the voltage of the battery and each cell
separate using those connectors and a battery voltage meter then we're going to
try to charge it using the two-way hub and hope if you don't get a low battery
voltage error so if you're having any problems with your battery and you had an
emergency and you depleted your battery now keep watching this video until the
end and I can show you all those steps that you know the ins and the outs of
your Mavic mini battery the way to measure the voltage of your battery each cell
separate if you want to measure the voltage of your left cell you take your
Plus put it in the first connector
in left side then you take the black one and put it in the third connector then
then your measure the voltage of the left cell of the battery because there are two cells
inside this is a 2s battery but I get no reading I got to zero from zero volts if
I you would use black in the second connector and again no reading
now I should get the overall voltage of two cells together so I fear the worst
for this battery, it sucks to be me but probably
is really death and brand new we take another battery we also got a number on this battery this number 2
I number each battery so we will not fly on one and the same battery all the time again show you
to measure one cell of one battery yeah put in the first connector and I put it
in the third connector and I get a voltage of three point nine volts just
left cell to first cell and I were using the first and the third connector on the
right side we get the voltage of the right cell it is three point eight point
eight almost three point nine you put it in the third connector and the second connector
you get the overall voltage from the battery two cells together 7.38 this how you
can check which cell is too low to charge but this battery is perfectly fine
in number two we have no measurement at all the zero voltage is
gonna be very curious to see if the charger will even still charge this
battery the charging hub is working the light is burning so let's insert the
battery see what happened yep start charging it starts charging was
completely at zero percent but it starts charging saving me $50 now let's turn on a timer
and time how long to charge a battery that was completely
depleted completely empty zero percent and can't believe the zero percent normally you
would stop flying around 20 percent then you still have to land and then you get
around 17 percent and then you are still safe if we do something similar with my
lipo batteries of my other drones the battery is depleted this empty is
over is dead I can go and throw it in the trash now we know how long it takes
to charge the battery of the Mavic mini from 0% to 100% in one hour
28 minutes and we know that the two way charging hub didn't give a low voltage
ever because the battery was really really empty so we brought it back from the dead and back to
life as we showed you how to measure the voltage of the battery together and each
separate so you can check the voltage in manual and troubleshoot
if you have any problems with charging it or I hope this video was very helpful
and please give it the likes they give the thumbs-up and if your not a
subscribe then please go subscribe I take the notification Bell and if your
battery is really dead and stays dead then you can find a link to a lot of good
spare parts that you like to have linked down below in the description I want to thank you for
watching this DIY Rc signing out Good Bye :D
