I have been using a 7" monitor for my pilot downlink monitor that has a power in and a power out. I would like to upgrade it to a 8" monitor that only has power in so I need a way to split power to the receiver and the monitor. Can the Lipo saver handle the current draw to feed both sources?
Dave: Good question. I can't find any data about the switching capacity of the MK Liposaver -- you may have to post a question on the mikrokopter.de forum. From visual appearances, it looks like there may be a MOSFET on the board, which would imply quite a large current, but if you get it wrong you'll turn the Lipo Saver into a one-time fuse. Andy.
Thanks Guys. I don't know the power of the monitor. How do you guys power both your FPV monitor and your FPV receiver?
Both of mine are able to accept greater than 12v, so I run a 3s lipo with a split harness for the power. One of my receivers has a built in low voltage alarm, and I use a balance port low voltage for the camera ops monitor and receiver.
I guess I could power one off the deans connector and have a deans connector to power connector to power the receiver and use the balanced lead with lipo saver to go to the monitor? I never tried using both the deans connector and the balanced connector for power sources off a lipo. I guess that wouldn't be a problem?
I wouldn't think it would be an issue. It's all the same power source, but you would lose the ability for the lipo saver to cut off all of the power draw. All of my receivers and monitors are powered from small barrel connectors. I just use one deans and split off to 2 barrels, with a lipo alarm on the balance plug.
I very much doubt it's going to be pulling 5 Amps, Dave. Can you do a Google search for your monitor and tack on the word "specifications" to see if you can find out the power rating online? Why not make a splitter cable? But, to answer your question, you can use the balancer lead and the main connector -- the battery charger does it. But the wires on the balancer cable are, of course, much thinner. Andy.
This thread reminded me to check my gimbal current draw, so I went ahead and checked my fpv monitor and receiver too. It's a 5.8 duo receiver and a readymade rc 8 inch monitor. Current draw is .6 amps
Thanks guys I like the idea of making a splitter deans connector and then just use the lipo for the warning.
Hey Dave, I was getting irritated with all the wires and Y adapters etc. so I opened up my fpv monitor and created a split of power etc internally. So now I have one wire coming out the bottom to connect my lipo. Then 2 coming out the top, one to power the receiver and the other for the video feed. So nothing plugs into the side of the monitor anymore.
