For a multirotor, just run a single positive wire from the power distribution board into the small hole on the board. The negative wire is redundant unless you are running on a plane.
Of course you can. Just make sure you use the ground and furthest wire on the balance leed or you will miss a cell. I just soldered it directly into the distribution board. That way there is no need to connect anything.
Thanks for the video, very informative. People use ONE battery should not connect GND. The reason is this will create multiple paths from the KK2 to GND, which creates a "Ground Loop". This is a common reason for interference and noise in electrical systems. It might noe be that big of a deal here, but best practice is to avoid it.
True and true but many people will use this with an airplane and bec or rx pack powering the board. Can be done both ways but I like this. That's my understanding anyway. Thanks for the comment!
This was very informative. However a quick run down on what voltage setting for say a 3s LiPo or maybe a chart indicating what the low voltage alarm setting recommendations are. I've just set up this board on my first quad and not sure where I should set this alarm.
Hi Don Thanks for this video as well as your others about the KK2 board. I have one on the way and will be doing this but soldering on balance leads instead.
Don, i may be missing something but might it be easier until i'm more experienced with the iron to just hook a Hobby King Low Battery Alarm to the battery? Thank You for sharing your expertise with those of us new to this !!
If you are using a power distribution board with your multi copter or a built in pcb all you need to solder is a wire from positive point on the kk2 board that was shown in the video to a positive point on your distribution poard or built in pcb. There is no need to solder a ground wire at all.
Also if your multicopter flies with 2 or 3S (my micro quad does so), you can set alarm for 2S lipo and in case of using 3S, just connect pin to the second hole from right in ballance connector to read voltage from only two cells.
You dont need to solder the ground, as your speed controllers are grounded to the board and the controllers to the battery. You can plug the positive end in the last pin of you balance port to get your voltage.
what voltage did you set the alarm too? What voltage was the lipo you plugged in? The balance plug would work if you use the far end wires only but I like just plugging directly into the power distribution board.
you could but I wouldn't recommend it. What I would do is use a custom Y harness to power the board and servos at the same time with out two power sources. That way you leave the door open in the future for multiple BEC's on the circuit. watch your power consumption too.
Just built a hex with the kk2.0 board & flies well,but my Q is this. The PDF I found on the board said that it gets it's power from the M1 point- all my esc don't have BEC so I hooked a UBec from the batt to the RX and then hooked the 4 jumper leads(standard 3 conducter) from RX to control board just for signal purposes(although IK u don't need all 3 legs for signal) and the kk board powered up. And that's how I've been flying it. My concern is that it said only to use the M1 to power it, or th
To repost from 12 months ago I run my 3s system at 10.5v to give me some time to get it back. Never let your lipos go under 3V per cell. They will drop off slightly before that. by dhdsracer Great vid thanks. Building a F550 with the k22. Got to love UA-cam.
Thanks! I had it at 10. I checked it and couldn't get it to alarm. I took it off and all my tinning is in the same places you show on the video, but when setting the limit to 13v it still would not alarm. I think I'm going to get the alarm from my second KK2 and see if that is the problem.
Informative Vid, but I have a problem with hearing high pitch tones, especially at a distance , so cud I put one of those small led's in line , with the tone alarm ? As I can/could see the light on or flashing ... Thanks
So If I wanted to set this up, all I would have to do is solder a connector on that part of the board, then run a lead coming from my main battery pack to that connector and it should do its thing.. I currently have a x900 Tricopter with no power board, just an xt60 plug and a lot of wires. I just have to tap into that to get a reading.. makes sense to me! :)
Im not new to RC, but I am new to quads. Ive got a KK2 on the way for my first build and obviously I am missing something here. The battery is connected to a power distributor setup that feeds to the esc's so where would you connect the LVA connector to the battery. Obviously this is a noob question, but Im lost on this one.
will def purchase thru your link! dude another awesome vid! keep it up! one question tho, would you be able to provide me/us with the links to the exact flux pen you use, as well as the exact solder you use in this particular vid? thanks so much as always!
Thanks man for this!!! I knew that the board could not possably know the full battery voltage with just the BEC 5v connection. I have been pulling my hair out trying to figure out what I am missing. I could not find any prints to go by or any literature on this. Please tell me where you got this info or how you figured this out. Without a print of the board their is no way to figure this out. Thanks again!!!
ive tryed all voltage seting with no luck... setting was 11volts and lipo voltage was 10.5 and settings didnt make any diff. ill try the distribution board. thanks for the help.
Thanks for the info, but I can't see the screen of the KK2 in your video because of the reflecting light :( What is the max voltage for the lipo alarm?
so i would need to hook up all power wires from the balance plug into one and ground to ground?... i tryed with just the ground and one power wire from othe side of balance plug and it will not work. thanks for the help.
Would like to have that battery tester you showed in your demonstration. Is that a HobbyKing item or other. I don't find it while searching. Thanks, Bob Oh, btw great informational video. It helped me, big time.
I'm confused about the two batteries? I have the SK450 from HK, with the PCB main frame, my power comes from the ESC's. How do I work this alarm with the connector you do?
You do not need to use the plug, you could just run Pos and Neg wires directly from the kk to your PDB, I think he used the JST from kk to pdb to make it easily removable? with out having to de-solder it. But he did not show.say to solder the jst from the pdb.. which i think added a bit of confusion to someone who is new. He used a small 3s just for testing. correct me if im wrong hair man child haha I have yet to do this but want to. now i just use a LVC alarm to the balance plug...
is it possible to solder all the positive terminals to each other for the servo's so I don't have to make a separate power source for it? Note that I'm going use the board for airplane stabilization
What is a good setting for a 3S? 3.1 per cell sounds kinda low! I would like my batteries to last as long as possible even though I may get shorter flight times. I've been setting my ESCs on medium and wondered what voltage that would be. 9.9v? 10v? Thanks for any info you provide.
hmm ok what do you use to link your ESC's together and to your battery? some use a spider wiring harness made from scratch, you would have to tap in to the pos and neg of them... search me on RCgroups if you like
I'm so confused. The KK2.0 board Input Voltage: 4.8-6.0V But you can connect a 3cell to the voltage alarm port? I just want to run off a single 3cell so Should I "Y" Split the red 5volt ESC cable into the voltage alarm spot - or "Y" split at my battery harness which is sending out 12volt? directly to the voltage alarm port.
i cant get it to work with the balance plug... i used the ground and the 12volt from the plug and its still willl not work. i got it hooked up like you show in the vid so i cant see why its not working.
For this voltage sensing circuit, since the board is already grounded to the battery is the ground really necessary and can you just connect the positive battery to the board?

Mark Johnston I did it like you said and it works as it makes sence :)
Hello man, i set the voltage alarm to 105 and i'm using a 2650mah, but when the battery reaches 11.5v the V.A. starts beeping.. it's supossed that the kk starts at 10.5v.. i'm doing something wrong?..thanks
i got it to work now.... for a 3cell lipo, it needs to be set to 105 so it works. if you set it to 10 it will never come on. it took forever to find that out, lol.
works great ,, simple mod ,, do you know a good buzz alarm setting for a 3S 11v ,, i have it on 10.5 is that a good ratio ? LOL ,, !! and you need firmware 1.2 for this ,!!
Why not just add wire of the negative wire to negative pin (esc negative pin that provide power) of the board of the one that provide power? This is something hk should even do anyways automatically.
For a multirotor, just run a single positive wire from the power distribution board into the small hole on the board. The negative wire is redundant unless you are running on a plane.
Thanks! this really helped me because I didn't understand what it was meaning by the Voltage 1/10th in the menu. Cheers for the video! thumbs up.
Of course you can. Just make sure you use the ground and furthest wire on the balance leed or you will miss a cell. I just soldered it directly into the distribution board. That way there is no need to connect anything.
Yes, as log as you are using the ECS connected to M1 you can solder the positive only. The ground will be redundant at that point.
Thanks for the info, I cant wait to get mine in the mail and put a connector on it for the low batt detector, thanks again for the help
Thanks for the video, very informative.
People use ONE battery should not connect GND. The reason is this will create multiple paths from the KK2 to GND, which creates a "Ground Loop". This is a common reason for interference and noise in electrical systems.

@FireN2k9 very true. I only say to do that so people using a seperate batter to power servos on a plane will still have the alarm. No harm ether way.
This was very informative. However a quick run down on what voltage setting for say a 3s LiPo or maybe a chart indicating what the low voltage alarm setting recommendations are.
I've just set up this board on my first quad and not sure where I should set this alarm.
It uses random numerical figures but more depends on what solder you use. Just heat up till you can melt your solder then go for it.

Never go past 3v per cell. To play it safe, set your alarm to 3.5-3.8 volts per cell. If your flying close, just set it to 10.5v and you'll be fine
@Pono421 Yep, just make sure you solder the plug in right or you will get just one or two cells connected.
what voltage did you set the alarm too? What voltage was the lipo you plugged in? The balance plug would work if you use the far end wires only but I like just plugging directly into the power distribution board.

Great vid thanks. Building a F550 with the k22. Got to love UA-cam.
Thanks for the helpful video. Is it safe to use 4 cell lipo in this without frying the board?
Thanks! I had it at 10. I checked it and couldn't get it to alarm. I took it off and all my tinning is in the same places you show on the video, but when setting the limit to 13v it still would not alarm. I think I'm going to get the alarm from my second KK2 and see if that is the problem.

The buzzer is included with the KK2 board.

Good video. Why HK didn't do this for you blows my mind
Nice demo. My KK2 board has a 2 prong pin that says "batt" just below and to the left of the buzzer. Is this the same thing?
Thanks man for this!!! I knew that the board could not possably know the full battery voltage with just the BEC 5v connection. I have been pulling my hair out trying to figure out what I am missing. I could not find any prints to go by or any literature on this. Please tell me where you got this info or how you figured this out. Without a print of the board their is no way to figure this out. Thanks again!!!
Nice!! doesn't it act as a Lost model alarm too? i thought i read that somewhere! alarm will go off after a set amount of inactivity?
If I understand correctly, we have to plug in the flight pack in twice?
Hello! Really helpful video! May I ask if I can use this function with a 4s battery? It's a 4s 5000mAh battery.
ive tryed all voltage seting with no luck... setting was 11volts and lipo voltage was 10.5 and settings didnt make any diff. ill try the distribution board. thanks for the help.

love your videos what buzzer are you using for this and where did you get it from? thanks for any info.
Where do you buy the buzzer? Does the KK2 board come with the buzzer, or did you have to make it or buy it?
muy buen tutorial, lástima no se vea bien la pantalla (display)
thanks what if you don't have a power distribution board?
What is a good setting for a 3S? 3.1 per cell sounds kinda low! I would like my batteries to last as long as possible even though I may get shorter flight times. I've been setting my ESCs on medium and wondered what voltage that would be. 9.9v? 10v? Thanks for any info you provide.
will the voltage alarm work if i use a balance plug insted if a jst?...
Can I solder a connector and for the balance leads? The black and red wires?
hmm ok what do you use to link your ESC's together and to your battery?
some use a spider wiring harness made from scratch, you would have to tap in to the pos and neg of them...
search me on RCgroups if you like
What wattage is your soldering iron? will a 25 watt be good?
How high will the voltage meter work? Will it go high enough for a 4s lipo?
Does your board automatically go from armed to safe when it hits a certain voltage? Mine does, and sometimes falls from the sky.
in what row did you connect the receiver battery? 10x
What would you set the alarm voltage level to for a 3S pack?
Would have been nice if we could see the screen at least. Anyway ty for video...
Lyrixish no kidding. I'm trying to set mine up and would like to see what's going on there.
I'm so confused. The KK2.0 board Input Voltage: 4.8-6.0V But you can connect a 3cell to the voltage alarm port?
I just want to run off a single 3cell so Should I "Y" Split the red 5volt ESC cable into the voltage alarm spot
- or "Y" split at my battery harness which is sending out 12volt? directly to the voltage alarm port.
but it comes with a buzzer and a voltage setting, it doesnt work?
i cant get it to work with the balance plug... i used the ground and the 12volt from the plug and its still willl not work. i got it hooked up like you show in the vid so i cant see why its not working.
Hobby King now sells an LED for the board.
Thanks for the info. I couldn't see the KK2 display , it was too bright.
You dont need to solder the negative (black) wire....only the positive (red) one :)
What temp do you have your iron set to?
10.5 is my personal setting.
For this voltage sensing circuit, since the board is already grounded to the battery is the ground really necessary and can you just connect the positive battery to the board?
Mark Johnston I did it like you said and it works as it makes sence :)
Hello man, i set the voltage alarm to 105 and i'm using a 2650mah, but when the battery reaches 11.5v the V.A. starts beeping.. it's supossed that the kk starts at 10.5v.. i'm doing something wrong?..thanks
Is it possible to solder all the posite term
How many volts provide that receiver pack?
Dose the buzzer come with the kk2 board?
thanks for the info vid helps plenty of fun guys keep it up
So if I plug my 3s 150c battery in to this it won't fry?
thanks mate, appreciate your video greatly!!!
i got it to work now.... for a 3cell lipo, it needs to be set to 105 so it works. if you set it to 10 it will never come on. it took forever to find that out, lol.
Hi good tutorial but the screen doesnt show up
all the best Mat
I forgot to mention that i'm using too a 2200mah battery and with this battery everything goes well..
where, misc settings volt alarm? how do you set decimals?
YES!
works great ,, simple mod ,, do you know a good buzz alarm setting for a 3S 11v ,, i have it on 10.5 is that a good ratio ? LOL ,,
!! and you need firmware 1.2 for this ,!!
is the voltage alarm needed?
Not really, but is can save your battery if you don't know when to quit :).
Why not just add wire of the negative wire to negative pin (esc negative pin that provide power) of the board of the one that provide power? This is something hk should even do anyways automatically.
thanks man like allways great info thanks.
Thanks dude... Legend
connect to flight battery to monitor voltage...
Nice video But you don't mention at what voltage you should set you set point.
Remember it will be be tripping under load.
Great vid...Thanks...
thanks for the video.
Sorry, it should be "People using.." above :-)
thanks, my battery uses an xt60 connection
Best part 2:16
My kk2.0 has no solder point on the board.
It's probably a KK2.1, which has a voltage monitor jumper on the top of the board.
it comes with a buzzer
Nice video - your knife looks bloody lol....
Uh huh. HK is a dilemma to me sometimes.
