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.
Spec. Transmitter Weight: 7g Receiver Weight: 35g (this is the part you keep in your pocket) Signal distance: Around 300-400mtr
Battery: 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.
Well, Trump, I finally stripped the f*cking battery and just soldered on a JST-XH. Now it charges, but as I put it in the receiver, the receiver appears to malfunction. I only get two red lights. Familiar to you? What to do? yfl211
I just got mine today. I plugged the tx into the battery ballance plug and the red light comes on. I then turn on the rx and push the button to select the correct # of cells. After it flashes a couple of times it beeps twice and then all the lights turn off. I cannot tell that it is working. Mike
Whwre is your stock. you are waiting good business by not stocking your popular items??? When will new stock arrive? I can get stuff I need real quck from other sources as well. You remind me of other businesses who carry the minimum to reduce overhead and the end lose business to others and once your customers leave they may never ever come back GET IT!!!
Of course not if you use the same freaqvensy, but with 3 different it is possible. This is absolutely the simplest form of telemetry. When the battery info goes throu the reciever (2,4GHz), it is possible to be many friends at the field and all can read their own battery status.
"The Wireless battery tracker monitors your lipoly via the charge plug" so you connect it to the battery useing it's service plug and you know what is condition of the each cell in the pack. It takes power from battery, it's simple :-)
That is exactly what I need for my 6S LiPo Go Motorboard 1500X. It's ESC does not protect my Lipo. This will allow me to monitor without fugly wires running all around. btw: Runs awesome at 24V up from the standard 16V 4ah Lead Acid pack
What about the situation when me and my friends are using those devices... all are operating on the same chanel... or different chanels??? I'm affraid of such kind of interferences and bad info on receiver. So, Imean what will happend when me and my friend use those devices in the same time?
If you have the same freaq. the reading will be wrong. All transmitting different info will be unusable. Use the Turnigy Receiver Controlled Switch and you can read at all times when taking turns of usage :-) Of course you are better off with different freq.
Yes, it's good idea, but it could be difficult to do this in such small item.
25 thumbs up!
Beware! You will NOT get the free battery as stated! I didn't get a battery and when I contacted support they wanted pictures of the packaging, everything inside it. a written note, my first born son, etc. They obviously will not believe you if you tell them they forgot the battery so you will have to spend more $$$ to buy one. AND they charged me shipping for the full weight of the item even though it was missing the battery!
I followed the instructions and after the receiver beeps 3 times, it goes black. The transmitter and receiver are not working properly. After reading these reviews, I see that someone else has experienced the same issue.
Not recommended. Beeps all the time when throttle is on. Really unuseable...

I have one of these and waht I don't like is that the cell voltage where it starts beeping is 3.7V. I expected it to turn red at 3.7V but mine would beep at 3.7V. I verified w/ a digital meter that it was close to 3.7V. That is too soon for making a sound and is kinda annoying. The Tx range however is really good. I had it down in the basement and could get reception all the way up on the 3rd floor.

The good decision for the control and calculation of time of flight and protection of yours LiPo. But unfortunately at battery tracker is a few lacks. In the receiver light-emitting diodes not brightly enough shine, there is no indication of inclusion. Loudness managed to be increased, having cut a label on a buzzer. The transmitter is strongly heated. I have ordered two complete sets and one has come with the faulty transmitter.
