Using 2-cell lead-acid battery as direct replacement for single
According to this article, it appears that lead-acid cells have a range between 1.93V and 2.15V which results in a 2-cell lead-acid battery having a voltage range of 3.86V and 4.3V. Will I run into any issues making the substitution to a 2-cell lead-acid battery in my system? Size and weight are not a big constraint in this scenario.
