.........When I did this, I had to add an extension from that battery pack to the regulator thus providing a voltage drop across the extension. .......... The voltage drop across the extension is what was causing this.
Thanks for that article and thanks to all who responded. Y'all are great.
If the extension is between the battery and the regulator, a voltage drop across it does not affect the output voltage of the regulator.
If the extension is between the regulator and receiver and there is no current flowing in the extension there is no voltage drop. So either the voltage must be set lower or the pack isn't staying 100% charged. It doesn't matter but make sure you check the backup so there is always some charge left.
