I tried writing a review and it looks like it got blocked. FYI to everyone. I bought two units, one worked fine on a standard quad and the second I tried linking up to a fatshark quad. I have usually powered devices through extra channels in the receiver which is how the first system is powered up and it looks like it works fine. The second however would not power up and I even payed special attention to protect my camera through volatage. I even swapped the second board to my first quad and it would not power up so I at least narrowed it down to the board. I then directly attached a 3s lipo to the voltage port and it finally powered up and I noticed it got pretty warm. So- the second unit would not power through the receiver but the first would- weird huh? So I spliced a red and black wire into the wiring system off the battery and it powered up and looked like it was going to work- however the heat of the osd was very apparent. I just let it do its think expecting a pop but the osd simply erased from the fatshark system. After letting it cool it would appear after powering up again but it would disappear. Not too happy with this product.

Hi, I have started to connect the E-OSD. When I power "BATT2" with my 3S battery, the red LED is flashing very quickly. Is it normal ?

How do you set PAL or NTSC? If I input RSSI max of 5v how high can you set the offest voltage on calibration?
 Alasdair 7 points
This osd will automatically set ntsc or pal. You need main battery voltage to be 2s-3s (I havent tried 2s) and second input voltage can be calibrated in setup calibration. It,s worth doing the primary calibration, I have two of these osd's and they both track voltage with reasonable accuracy only after calibration, however if one cell fails early, the group voltage being displayed, may not show an under voltage failure in the pack, as it only reads total pack voltage, not each cell.

WARNING! Don't use it on 4S battery! It might fry the OSD. It was working on 3S, and I just fried mine when connected to 4S the first time. Get the "Super simple mini OSD" if you need to run 4S battery.

they changed the description to 2-3s only
 Z 82 points
they never say 4S on this product, but a few people here commented they have success running this on 4S, which is highly risky. I just want to point this out.
 Adam Dube 214 points
sorry I just didn't want to call you out when the product description and the product manual states 2-3s. I see a lot of people complaining about products on this site when they have clearly not set it up properly or have failed to read anything at all......
 Z 82 points
But you can't deny the fact there quite a few products on this site are mis-labeled. a good example would be the 12A ESC which are labeled 2-3S, but in fact runs on 2-4S. I could have said nothing, but I wanted to warn anyone who is tempted to try.
 Adam Dube 214 points
you are completly right
 Adam Dube 214 points
did you end up getting a new unit?
 Z 82 points
no.. I am going to get a G-OSD which is rated up to 24V. cost more, but I don't want to take chances this time!
 Ricardoliveira 10 points
i use 4s no issues and some friends also.
 Alasdair 7 points
You can trick this E-Osd into running 4s or up to 6s, if you use a resistor voltage divider, then simply feed it 3s voltage, but calibrate it to read 4s numbers. No fritzing then.
 Adam Dube 214 points
Great idea! How many ohms?
 Alasdair 7 points
As the osd draws minimal current, and you're calibrating anyway, to drop 25% voltage, series a 330 ohm and 1k, run 1k from negative, 330r to positive, sense pin to junction between the two resistors. 1/4 watt should do fine, total draw from resistors will be about 10ma.

This OSD can successfully measure a 4S on Batt 1 without problems as long as you supply the OSD with max 12V on Bat 2 (you prob have a 12V reg anyway for your cam when you use 4S)

Just got mine. Works fine. It is worth the price. Pretty simple to monitor FPV pack battery or motor battery (if under 3S). There are some interesting projects to do RSSI monitor (check rcgroups). You have to to make a Y connection between camera wire and tx wire to the OSD (video input) i.e camera signal and tx signal going into video input on the OSD. Gnd can come directly from pack.

cheap OSD with minimal necessary functions. Good when you do not need all the ET gear onboard

Worth every cent! Easy to calibrate and clear text on screen. Use it on my FPV multicopter to show main bat V and Video Tx V. If your into FPV you need this good cheap reliable OSD! To marks HK :-)
