Hey guys
so came across a compact easy ground station
https://www.youtube.com/watch?v=S2wnS1T5haY
made myself one the only thing i added was lipo battery checker inline that has a momentary switch wired to it (only display voltage when i press the button). after using it for sometime thought it was great. One of my close friend is getting into quadcopters and fpv. for his birthday decided to make him one to get started.
i have everything WORKING except the voltage display. everything is wired in parallel to keep the voltage the same everywhere. the voltage display comes up as ALL 5.7v then Cell 1 ERR and repeats. how am i getting 5.7v from a 3s lipo? use a different battery checker same thing. substituted a different battery (known to work) and same results.
at first i though it could be the battery. when i connect the voltage display directly to the battery balance lead 12v. thinking it could be the main battery lead, check that 12v. battery is fine. i thought it could be the momentary switch i wired in (dint think it could be since the previous build is using the same thing). took the switch out of line and wired without it, still get the 5.7v.
i literally tried to wire this every which way i can figure. the only time the voltage display works properly is if i wire it directly to the battery. as soon as i tried any wiring scheme that is not directly connected to the voltage display i get 5.7v. how is this possible? how is it steeping down in voltage?
any help ideas you can give would be awesome
i can take pictures/videos of the different wiring and the results if someone is really interested to help me figure it out.
what baffles me most is i literally have the EXACT same setup working. same parts and wiring, same everything.
