Simple version: 3.7 volts in an IMR (lithium-ion) rechargeable versus 1.5 volts in a typical, single-use alkaline.

High-discharge means higher RPM in flywheel blasters, higher muzzle velocity and longer range. In a non-flywheel blaster such as Speedswarm, Swarmfire or Stampede, it means higher Rate Of Fire, but longer distances would require a spring upgrade.
