Hi all,
I have two rather large Aerial Photography platforms outfitted with Pixhawks. One runs on 6s and the other on 12s. I need to solve the voltage sensing problem.
In both cases, I have no interest in sensing current (partially because it would just blow the AttoPilot 180A or equivalent board), but I would like to be able to read the voltage of my flight packs. I found many 6s capable voltage sensors, but they are all designed to be used as current sensors are well, where all the power flows through that one little PCB. I don't think this is practical in my applications, so I'd just like something to read the voltage and not be responsible for conducting any of the current. Is there an existing product or a (fairly simple) solution to this problem?
Here's a picture to show what I'm trying to say
Thanks in advance for the help!!

What I ended up doing is creating a voltage divider and feeding the output of that into the module. This is in parallel (not series!) with the load. You get your voltage sensing capabilities, but no current sensing.
