The play enhancement system includes a first power source and second power source for selective connection to a circuit board in a projectile hopper for the projectile launcher. At least one of the first and second power sources comprises a rechargeable power source. A switching device is connected to the first and second power sources, and to the circuit board for selectively connecting the first power source or second power source between a power source recharger and the circuit board. Continued play is provided by switching between the first and second power supplies when a predetermined low voltage is reached.
