<p class="MsoPlainText"><span style="color:#1F497D">It is not recommended to replace one bad unit by a new one in a 1 year-old battery bank. That will definitely unbalance the strings.
<o:p></o:p></span></p>
<p class="MsoPlainText"><span style="color:#1F497D">Modern solar chargers and inverter-chargers typically have settings adjustable to reset to handle a previously 48V battery bank configuration into a 46V battery bank configuration with the healthier units.
Please consult the controls OEM’s for how low the newly configured battery bank voltage can be handled if there is more than one bad unit. I understand the max is 3 units on a 48V bank. To be confirmed.<o:p></o:p></span></p>

<p class="MsoPlainText">Yes, indeed. But--- would one defective cell bring about the early demise of the other two in the same case? If this occurs after one year of age, are we advised against changing out the one bad battery and required to replace all
of them?<o:p></o:p></p>

<p class="MsoPlainText">More questions seem to occur the more we think about this idea.<o:p></o:p></p>
