I ended up creating an extra table for "system data" in MySQL, then added the following custom SQL code and configured it to run every 5 minutes:

Configured under: Settings > MySQL Settings > Custom upload - minutes interval

Code:

INSERT INTO System (LogDateTime, BatteryVolts) VALUES( NOW(), '<#battery>');

I'm happy to elaborate further if anyone is interested, but it's hard to answer the original question without knowing what software vk2kzo is running.

I would be interested in seeing this if you are able to. I am on CumulusMX also and have managed to implement the current battery volts on my Saratoga template using the appropriate web tags.
