Turnigy Voltage Detector is very accurate and easy to use. The 3~8S voltage detector will give a warning buzzer as well as LED indication for High, Average, Below average, and Low voltages on your Lipoly battery. It's very easy to use, and only weighs 6g. The buzzer is also quiet loud. It's varied warning range is great for those with gliders that need time to bring the plane down from a high altitude.
Turnigy voltage detector has polarity protection. Operating Voltage : 9~33.6V
Why so cheap? This is an in-house designed product, and you're paying factory direct (hobbyking) pricing!
I hav bought this beeper but i have a queation. On the one side there is a plug for the balancer of the battery. On the other side there are two cables. Do i have to solder them betweem my esc and my batery?
SteveAT NO Balance Plug sorry. One end is the PINS to select the Battery S rate (3S to 8S). I made a little plug for mine. I got Male and Female connector. Soldered back to back, soldered this item between that and heatshrinked it. But yes it goes between the Battery and ESC.
I cannot review this iten here because I bought it from HK holland... anyway, dont buy it, it's worthless; beep is to faint and it only monitors total power, no individual cells. This beeper is better:
Dont know if the link will be accepted, anyway I mean the Onoard Lipoly Voltage alarm. Much louder beep & individual cell monitoring (and simple connection through the balance plug!)
That "tiny black piece" is called a 'jumper'. This jumper is an electrical connection between the two pins. Moving the jumper allows you to choose the battery voltage you wish to monitor. By selecting the 3S position for e.g. it tells the detector you wish to monitor a 3S battery. 3S denotes the number of battery cells connected in series. A standard lipo battery cell is rated at 3.7Volts (per cell), & 3 x 3.7V is 11.1V. 11.1V is the nominal voltage of a 3S lipo battery.
why solder , no plugs are soldered ,no just criped join , Many forget this simple crimp . tho i like to cover the tip with solder before I crimp a Plugs wires into the gold connectors, , have good fault free join, , have good fights,
basically, you have to make your own. I took two XT60 connectors and soldered them together with the detectors leads attached so I could plug it between the battery and esc* then also be able to move it from platform to platform.
You just have to wire it inline with your power supply. I soldered two xt60's together with the detector's leads so I could plug it between my ESC and battery* also allows me to move it from one platform to another easily.
I bought these but am not understanding the rave reviews- please correct me if I'm wrong but it seems like you don't even get a flashing warning (which isn't so great if the plane is in the air) until the voltage is at 3.7V per cell which is a 91% drained lipo already and much lower before you even hear the audible warning-I just don't want to drain my lipos that low (as the theory goes, you are not supposed to drain your lipos more than 80% - if you want them to last), so I'm better off timing my flights so I don't get below an 80% drained lipo, rendering this product pretty much useless (& I purchased 4 of them..)- IMHO- these need to to start the warnings at 3.79V per cell (~70% drained) etc ..or better still, be user programmable - not useful for regular flying to tell me when to land bfore damaging the lipo- this is just a very last resort warning, moments before the lipo is virtually drained completely..
thanks but I wanted these so they tell me when to land whilst flying, but not have the first audible alarm be when the lipo is more than 75-80% drained- my purpose isn't to generally check the lipos' voltages - by landing and then checking- - the best product I believe on the HK site is PRODUCT ID: Voltage-Alarm- you can program a higher low voltage alarm (as high as 3.8V, which is as low as I want it to go before an alarm sounds) and is apparently louder than 'TGV- Detector'- and only less than $1 more than 'TGV- Detector'- the only thing is 'Voltage-Alarm' seems to be always out of stock at HK- so I ended up ordering 4 'Voltage-Alarm's from a different competitor store..
SigiK- you're in luck- HK just received a new supply of PRODUCT ID: Voltage-Alarm- get in there whilst you can! at least you can benefit from this- as I said in my last message- I just ordered from another company just to get them- whilst I could have added these to an already large order I have with HK and have saved on shipping.. oh well
They work just fine. You can run a lipo down to 3.3V per cell. Storage is 3.8V per cell. The idea is as the cells reach approx 3.7 V per cell the warning light and buzzer startup. That gives you enough time, more than a minute on a prop plane to get it on the ground flying at a reduced throttle level.
Hey Jay. This is not a balancer go any kind. This is just a thing you put on your R/C device and connect it to your Battery and it makes a hell of a noise when it drops down too low :-) Hope you like it.
There are a lot of LiPo charges / balancers available in HobbyKing with very low prices. You need one of them in order to balance your pack. The Turnigy 3 to 8s Voltage Detector is used only to warn you when the voltage has dropped below a critical level. It works for packs from 3s (11,1volts) to 8s (29,6volts).
Not loud enough to be heard from a flying electric plane.
A newer model HK now carries, including three-digit display and TWO buzzer, with programmable threshold voltage should be your choice for airborne battery monitor
I have some also. Try velcro or banding it to the outside of the plane by the hatch and also peircing the shrink wrap over the speaker hole, this improves the sound but the newer ones with display are better.
I'm trying to figure out how to connect this to the battery - I understand I need to get a female balance connector- but this product only has black and red wires connected whilst balance connectors have 4 wires soldered- black, yellow, blue and red- am I right in guessing that i just need to solder black to black and red to red and forget about he other 2 (middle wires))? also some of you are mentioning to use the ESC connector so you can swap between different planes, battery packs whether 3, 4 , 5 cell etc (as putting a 3s balance port connector will of course limit you to just 3S lipos only)- however what do you mean by the ESC connector- my ESC just has the channel plug that goes into the RX- how would this connect to this voltage detector as opposed to the female balance port plug? thanks in advance
OK, the balance connector is negative (ground) one one side and positive on the other side. The wires in the middle are taps of the individual cells. A 3S pack has four wires. One negative wire, the black main power wire, and one tap on each cell. The cells are connected in series. If you use a meter and measure from the negative to each wire tap, you will see progressive voltages. The firs tap is 3.7, next is 7.4, and the last is 11.1. Connect the black wire to the negative side of the monitor and the red wire to the opposite side. Set the jumper for the number of cells you are monitoring. You can also connect the monitor to the battery connector on the ESC. Just solder the black and red wires to the connector like the ESC. Each wire will have two connections. Last you can make a battery connector that has a battery side and ESC side back-to-back. In the middle, solder the monitor wires. This has the advantage of allowing you to easily use it on different packs (3s, 4s, etc) by just changing the jumper and connecting the monitor.
it can be used in lipos of 3 up to 8s, it is only to also weld the red thread in the lipo and the black and to select which is to your lipo in the (jump) that exists on the subsequent side, verify that has been marking lipo of 3s up to 8s and oh you select, ok!
This monitor have LED info two, other is only sound but have connector for battery.
Consider On Board Lipoly Low Voltage Alarm (2s~4s) PRODUCT ID: DL-Volt-Alarm if you only need sound alert.
I solder 3s balance connector ( female) to Voltage detector,entering wires to balance connector was problematic.
It's perfect if you haven't telemetry system. It beeps when the battery is near the minimum li-po voltage ( you will have enough time to land ) also it tells you (on ground) via LED if battery is fully charged, little discharged or fully discharged. It's much better cause it support more voltage options (not only 3s - 3s~8s).
is very easy on the back of the voltage controller have a jumper which I removed and placed in the appropriate pin using a 11.1V battery put it in 3s, 4s and 14.8V in the 8s pole so that gives the driver
You need install jumper to correct position ( 3S, 4S, 5S, 6S, 7S or 8S) accordin your battery, then connect red wire to positive and black wire to negative power line. For exemple, you can solder it to ESC power connector.
Use the ESC connector. This let's you move it from one plan to another if you want to. It is easy to add the balance plug connector and use on other planes with the same voltage. These are not expensive so you could make one for 3S, 4S, etc. depending on the packs you use.
what do you mean by the ESC connector- my ESC just has the channel plug that goes into the RX- how would this connect to this voltage detector as opposed to the female balance port plug? thanks in advance
voce pode ligar junto com o conector do esc, sem problemas, a funç*ã*o é* apenas de monitorar a bat para ter uma ideia da carga restante, deixe do lado de fora do aero, que facilitara visualizaç*ã*o, e ouvir os bips.....
Hi, it will ONLY monitor the Overall voltage of the battery. This will connect directly to the " " & "-" of the battery pack. Here's a more suitable product for monitoring individual cell of your LiPo Battery. Product SKU: PRODUCT ID: BM-6 Product Name: BM-6 Cell Voltage Monitor 2-6S Lipo (New Version) Hope I have given a Good Answer and Good Reply to your question :-)
This voltage monitor can be connected across the leads of the charge port & it will monitor 2 to 6 cells based on where you put the red wire & the jumper but only the total expected voltage for that number of cells.
For example, it does not have 6 wires to monitor each cell of a 6 cell pack. You need a cell monitor/balancer that you can find on the HK website also.
Hi Pal, this voltage detector utilized the power from the battery pack you are monitoring. Most battery pack comes with "Balance Charge Cable" that has 3-wires (for 2s LiPo), 4-wires (for 3s LiPo) & 5-wires (for 4s LiPo). This Voltage Detector can connect with the battery's Balance Charge Cable. All auto detection. very easy to use. Hope I have provided you a good answer to your question :-) Cheers!
you can connect it directly to your battery ,
I use it to monitor my 3 Lipo cells in my transmitter , soldered directly to the on of switch. Only 2 wires red and black the rest of the pins you see is for selection with a small plastic bridge of the number of cells you are using 3 to 8 cell's
Works great .
Hei guy, this is just an alarm to be used onboard. If you use a Lipo 2S you have to put the jumper at 2S possition. If you use 3S, jumper at 3S possition, etc. It has no screen to see the voltage, it just buzz when average voltage per cell is bellow 3v
Hi. I connected a 3s lipo batery and I didn´t notice that the jumper was not connected. I disconnected the battery and conected the jumper in the 3s pins, but now when I conect the lipo again the detector start beeping even with full charge. Do you think the the detector is broken? do you have any idea of how can I solve this? best regards
What harm will it do to leave the led! its a multi stage warning system first lights flash then the buzzer it works well with visual led audio buzzer warnings ... to stop the LED put a drop of paint over it its soldered to the circuit board!
Okay now i can hear it but it won't quit makeing the noise now, hooked up to 4s lipo with the jumper on 4s, hooked in to my ar6200 reciever. any ideas how to get it to shut up :> And yes the battery is fully charged.
do you have another battery you can test your voltage connector on? I'm assuming you've connected it correctly to the battery (connecting the voltage detector parallel to the 4s battery). Also check the pins on the side, maybe some of the pins used for higher cell batteries were bent and are touching? This is me guessing though, I think it is likely that you have a defective one.
Correct me if I am wrong but was it working before you made the fix for louder sound? If so then maybe a small metal piece might've fell inside the heat shrink onto the circuit board? If a metal piece connected the right lines then a higher cell battery would be selected meaning the minimum voltage it is looking for would be higher since the number of cells is higher. Thus leaving it to believe your fully charged 4s battery is actually or low charged 6s or 7s, etc. etc.
Goodluck, hope you find the problem
I had the same problem. One very simple way to make the buzzer a bit louder is to cut a bit of the transparent heat shrink covering the buzzer hole. Only cut enough so the heat shrink hole and the actual buzzer hole are the same size. This will help a little. Also make sure the buzzer is pointed downward (on the bottom of the plane/heli) since this direction will help direct the sound toward you. Less physical interference of the buzzer will definitely help too.
When I order from HK it's usually a large order to compensate for high shipping cost and make it worth the time/money. If I just ordered that 1 item I can understand the 19 grams, but when I order a dozen others things it feels like your ripping me off on shipping weight!!
The actual weight of this device instructions plasticbag is 9.1g, but then there are the added weights of the needed box. I'm sure they take a small proportion of the actual box size and add that in, I mean HobbyKing won't just stamp an address on the plastic bag and ship it internationally! 19g is a bit of a jump but this very important item is definitely worth the $2.50 which would definitely cost a lot more elsewhere.
Are you saying that the jumper is not included?? "the other side of the jumper cable"..Do you mean the red and black wire? If so they goes to the battery you are using. If it is 4 cells, the jumper has to be put on the second from above pin row, were it says "4S" on the sticker.

Excellent product. Error is on the transition from "high" to "above average" from 3S to 8S for the final transition from "below average" to low for 3S to 5S <2 for final transition for 6S to 8S. There is a ~20mV hysteresis for the "high" to "above average" transition ~100mV hysteresis from "above" to "below". Once below the "low" threshold, the beeping does not stop even if the voltage recovers fully.

Some odd editing happened to previous entry ... Less than 1 percent error transitioning from "high" to "above average". Less than 2.2 percent from "below average" to "low". Much better accuracy at lower volts.
Well great thing.But i thought it measures the individudal Cell ! Thats not the case! It measures the whole pack and by a jumper you have to choose the cell count of that pack beforce connecting!!

This is a great little product that I use myself every time I fly. It's cheap insurance for your expensive gliders and larger scale planes. Who needs fancy telemetry and expensive systems when you can have peace of mind for a few dollars!
