13. What effect does battery voltage (V) have on the replica’s performance? Can I use a battery with a higher voltage (e.g., 11.1V instead of 7.4V)

Higher battery voltage increases the replica's rate of fire, improves trigger response, and increases motor speed. However, it should be noted that it can accelerate wear of internal components. 11.1V batteries are designed for more robust replicas equipped with a MOSFET circuit.
