Wish you could know your Lipoly battery voltage while you are flying?
Want to be able to accurately know when your pack is about to drop voltage?
The New-&-Improved Hobbyking wireless battery tracker monitors your lipoly via the charge plug and sends back a signal to your reciever. Should one of your cells drop below 3.6v the LED for that cell will turn Red. Once the cell drops below 3v the LED will flash and the warning buzzer will beep, signaling you to land as soon as possible.
This unit is also a great way to find those batteries that drop voltage greatly under load.The transmitter operates on 869.0Mhz FM band and can monitor 2S to 6S batteries.
Transmitter Weight: 7g
Receiver Weight: 35g (this is the part you keep in your pocket)
Signal distance: Around 300-400mtrBattery: 7.4V/ 2 Cell (Included)Usage;
Ensure the hand-held receiver is turned on and you have selected the number of cells first. Once this is done, then connect the transmitter inside the plane to the batteries balance plug. If you do not do it in this order, the reading will be incorrect.

This is not a good product. Mine works as long as the transmitter is less than one meter from the receiver. The transmitter label is pasted on backwards, reversing + and - indications. The receiver battery is a 1S lipo and I charged it first. There is nothing written on it so I charged it at .1 A. I would give it zero stars but that is not a choice.Not recommended. Beeps all the time when throttle is on. Really unuseable...Con un motor de alto consumo te avisa de bateria baja con normalidad ya que si el voltaje de la bateria baja por debajo del minimo que opera el aparato salta la alarma pero al cortar algo de gas para la alarma, es muy util cuando vuelas cerca y con un avion poco planeador.Works great!
Starts beeping intermittantly when my battery is at about 50%, beeps continuously about 1 minute before my low voltage cutoff happens. Very good investment!Bought two of this and use them in my twin motor catamaran with two 4S 5000mah Turnigy li-pos and this "tool" is very helpful to protekt your cells.Nice product.The only thing that wasn't good was the bad battery that was included.I use it with another battery which is external cause it is bigger.No reply to my email at all and no spare battery to buy extra for this item...Anyway... if you are lucky and your battery is ok , then this product is fine.It works butt it beeps earlier then what i want.First, there was only partially function. Then i have found out, that the connector case-side makes not sure connection, it seem's to bee a little smaller with the pins. So i have soldered an other one (f)-JST, and since there, it's perfect!
I also have mounted a little 2S-Buzzer for the internal Lipo on top of the case.
This is a absolutly perfect tool, and i'dont want to miss them - and it's also fantastical cheap!This item is working exactly the way it is described. A very good solution for my receiver lipos that power my Turnigy Power Unit for my bigger planes instead of placing a volt watch that needs another channel on the receiver.
The only con about this unit is wether shall I be able to find a spare receiver lipo with the same specs???? Thanks HK., .. . , ,
