If all that didn’t make you nauseated, I can loan you, or you can purchase for about a 100 bucks a data acquisition logger which will generate the purdiest curves of the battery voltages when you run your full cycle test. https://www.dataq.com/products/di-1100/

There are two very good reasons for running a full cycle test. One, it is a great way to baseline the battery bank capacity. Cause five years from now, you will wonder if they are still as good as new. But more importantly the full cycle test identifies the inflection points at the charge and discharge ends of the curve. Knowing those inflection points allows you to set your recharge voltage and your LBCO with a high degree of confidence. And since I have a homegrown battery monitor system for overprotection, I needed to know where to set the alarm and power cut levels to provide protection to the bank.
