A Different Battery Question
I did pretty much what you said except for the recording and measuring
part.Â* My ClearNav and my Dynon D10a each have a volt meter displayed and, though they had slightly different readings, they seemed to track pretty well as I turned each device in turn. For now, I'm gonna go with charging the lithium battery for a longer period after the green light comes on, probably over night each time. Thanks for all the good advice!

My $0.02....with even an inexpensive DMM/DVM.....start at the "common buss" on/near the panel with all batteries fully charged. Measure D.C. Voltage at the buss main input with a battery connected.... Switch things on, read voltage....write it down.... Key mic and do other load things...record voltage under load. Repeat with the other battery..... If the large battery shows a bigger voltage drop.....work through connections back towards battery with same test....see where the voltage drops lessens....in between good vs. bad/poor voltage drop is likely a poor or bad connection. Could be a bad crimp, poor solder joint, loose/poor screw connection, maybe even small wire gage (although not likely unless waaayyyyy tiny...). -- Dan, 5J |
