The starter motor is powered by a 12.8V LiFePo4 battery pack (14.2 when fully charged). Sadly, even when the battery is freshly charged, the motor won't turn over unless the charger is still hooked into the circuit. (Somewhat inconvenient at remote locations.) Can I hook a 5 cell 15.0 V (3.2V X 5) "Booster" into the circuit to give the extra push it seems to need?
I have a 12V starter motor that needs extra help at times.

To me it seems like the battery can't deliver enough current to the starter motor. I would not try to raise the voltage since the starter motor is rated at 12V. When the battery is connected to the charger the charger helps the battery to supply enough current. To be sure I would look at the starter motor specification. Look for the wattage or current specification. Also look at how much current the battery is specified for. The battery must be able to deliver as much or more current than what the starter motor needs.
Two solutions to the problem if my suspicion is true:
