HXT Lipo Monitor 3S. A must have for all lipo users!
HXT Battery Monitor for 3S lipo.
This device plugs into the balance port on your battery.
Should any one of your cells fall below 3.3v the light will change from Green to Red, indicating an unbalanced pack and that your battery should not be discharged further.
Discharging your pack to its normal level when you have an unbalanced pack will cause one cells capacity/voltage to drop too low, resulting in a faulty cell which will very quickly reduce the packs performance.
A properly balanced pack can last 600 cycles or more. However, unbalanced packs rarely make it past 100 cycles before at least 1 cell becomes faulty.
We strongly urge all customers to balance and discharge packs properly.
With this device, you will know immedietly when your pack is unbalanced and should not be discharged further or balanced.
Hey guys, I'm thinking of using this monitoring system for fpv gear inside of a full sized car that I'm working on, but I dont know wether or not this system stays on as long as it is plugged. Or if it shows the reading then turns off. Can you guys help me out?
This particular monitor is only made for up to 4S. I recommend using the monitored linked to below instead. It does the same job and more :)
Recommended!
You can have it connected while using the battery or just connect it and check when you feel like it www.link
Has anyone tried to us this and the HXT lipo monitor at the same time? I was thinking I could solder the lipo monitor's leads onto the two corresponding pins from this monitor and get a 2-in-1 monitor. If I were using this on a 3s, do you guys think this would work? Is there anything I'm missing? Thanks, Dan.
No, I have used it plugged it, but I was wondering if anyone had tried using the two monitors together... Soldering the other one on this so they could plug in together...
Each LED measures the voltage of one of the lipo cells in your lipo pack. A LED turns from green to red if the voltage of the cell drops below 3.3v. So one led can turn red, while the other led's are still green. As soon as one led turns red you should stop using the battery. The LED's are bright enough to see them on a flying airplane from the ground. (I attached this device on the outside of the fuselage)
I can confirm that this product will not give a warning sound, because it even does not have a buzzer on it. It has indicator LED lights that will show you battery cell's status.
No. I just checked. Two of them side-by-side have too wide a gap between the inner two pins. Consider the www.link It even has a "hold" button that allows you record the lowest voltage in each cell during a run. The numbers are small -- see the reviews
it has 4 pins for 3s so 2 would equal 8 pins.
How many pin does a 6s lipo balance plug take?, 7 pins I think, I don't use 6s batteries I can't see it working for you!
No, you would miss one of the cells, since you'd have to put the inside pin of both monitors into the same hole, and that probably wouldn't fit without breaking something. If you just put them in next to each other they wouldn't measure the cell in between them.
Does anybody know if there exists any lipo monitor or something like that which can I plug in some ultra light LED which is gona be switched on when voltage is going to be low. I mean a LED which might look like taxi and landing lights (swiching on automatically when voltage is low).
Tharindu: 6S lipo balance plug have 6 positive wire, not one because the cells connected in series. A cell positive wire is the next cell negative wire.
Best use i have found for this is bench testing and setting the timer on ur remote i put 22oo in my hk-P51 changing the throttle settings like a real flight with 75 WOT i got 18 min b4 the first red light on this little shiner, so i set my timer for 12 min and have 4 min to land and then 2 min emergency hope this helps (ps it is not bright enough for me to use in flight)
Yes, it is work. You have to plug the Ground outlet to the ground connector and the other outlet to the neighbouring connector and one led will indicate the voltage of the one cell.
Yes they have. You can just use an adapter from female JST-XH to male Kokam for example if you're using batteries with JST-XH. I tried it out a minute ago and the Kokam connector fits perfectly in the Lipo monitor: 101b-104a-3s
Works with 2S and even 1S. No need for an adaptor. Simply always keep the minus pin connected to the minus on the balancer plug. It's almost like a reference pin. Beware though! This monitor does not contain any sound alarm.
I think HS should start suggestion box..where customer can suggest to HS new product which is they like HS to bring in.. I have one which is better than hxt lipo monitor..go to ***********maxprotechnic****/Maxpro/Technic/MaxproBM .html ..this monitor got very loud buzzer and very visible light
Hy. It is advisable to stop when one of the battery cell power is below 4.2V (one led turn to red) because of the difference of the cells, the weaker cell can go to deep discharge when the another cell is just going into red. If one cell go into deep discharge it lose capacity end the lifetime become shorter.

Excellent item, barely weighs 3 grams with leads to battery. I have found that if you remove the SMC resistor connected to the red LED, the LED is ALLOT more brighter. Before I removed the resistor it was a dull red when the voltage drops below 3.3V/per cell, now it can't be missed, either during day or night flight.
I also found out that my charger was not balancing my cells properly and one cell would drain faster then the others, this item indicated that one cell was drained compared against the other cells. Save me from completely destroying my Lipo packs :-).
One down side to this item is that it does not provide a way to determine voltage between 3.7-3.3V/per cell. If the LED color could transition to green, yellow, orange and then red at 3.7V, 3.55V, 3.40V and 3.3V per cell (respectively) this would make this item much more impressive and useful.
Still great tool to have on board.

Works as advertised. I use mine to spot check packs before charging on my balancer. Cheap and handy device. FYI, this works on all my HXT (Hextronic) and Great Plane's Lipo packs. Also, this can be used to test 2S packs. Keep the positive polarity right, and just let the 3rd negative hang off the side. Next time, I'm buying a 4S for this reason.

Small, low cost, lipo monitor. The LEDs are driven at 2-3ma. Hence bright enough for indoors, might struggle to see outdoors. The switching points (LED first on and full brightness) were as follows: 3.26/3.2 3.24/3.18 3.19/3.14

A nice item indeed. Well made & lightweight design. Easy to use & instant L.E.D read outs. Plug & play,keeps you in informed while flying or quick checks at the field/home. An excellent investment.

I've already sold about 50pcs of these tiny gadgets. It is more than worth its prize. Every customer who buys a new helicopter-set with a 3s battery buys this monitoring device. It's so simple to use and robust. If you put it into the JST plug the wrong way, nothing happens. Just turn it around and it works. The only thing to keep in mind is, that you unplug it while storing the battery. Otherwise a deep discharge occurs.
Everyone should use it. Totally satisfied, very much recommended.
