iSpindle battery indicator

[LEFsher]

Hi Guys, first off thanks for the wonderful work you are doing on this software system 👍🍻. I have a question, during a fermentation the monitor display for the iSpindle gives all the details, Temperature, ABV, SG, Duration including the battery level in the chart header. Yet once the fermentation is completed the battery information disappears from the saved chart/document. Would it be possible to keep the battery final voltage in the saved version, it would give a good history of battery use and "final" levels helping with understanding when the battery may be on it's last legs.... Just a though and not a high priority, maybe a nice to have in the future 👍
