First off, I realize battery voltage is a very poor indicator of battery health or how much juice is left "in the tank", but until I scrounge up a few hundred bucks for a battery monitoring system, this is the best I have.
My house batteries read 12.6v without any lights on in the RV.
Turn on a few lights (overhead, galley, bathroom) and the voltage drops as low as 12.2.
Turn the lights off, and the voltage recovers to 12.6.
Is this normal? Am I looking at replacing my house batteries?
The main reason I ask is my wife noticed the voltage as low as 11.8 while getting things set up for a trip this weekend... but I think she had every light in the rig on at the same time.
The RV is a 2017 Winnie ERA 170M. The lights are all LEDs.
