Even when in a stable rested state, the voltage is not as good an indicator of battery SOC as the temperature corrected hydrometer reading.
The cost of a hydrometer (could be under $10US for some decent ones)------- is small compared to the value of saving the life of your battery bank. +SunnyBoy 3000 US, 18 BP Solar 175B panels.Comment
