The Rechargeable Battery Pack is a Nerf accessory that was released in 2017 under the RIVAL series.

It comes packaged with a wall charger, which is used to charge the battery itself.

Details
The Rechargeable Battery Pack, as its name suggests, is meant to be a rechargeable replacement for using individual batteries in battery-operated RIVAL blasters. It is a nickel-metal hydride battery and is intended to replaced six "D" batteries as a lighter and cheaper alternative in the long run. The battery has 7.2 volts, which is less than the 9 volts one would get from six "D" batteries. However, it sports more current and thus, increases the blaster's performance. As such, the pack is advertised as increasing a blaster's rate of fire.

It is compatible with the Khaos MXVI-4000, Nemesis MXVII-10K and the Hera MXVII-1200 ; it is not compatible with the Zeus MXV-1200, the Prometheus MXVIII-20K, Soldier: 76 Blaster, and the Perses MXIX-5000, as their battery tray designs are different from the rechargeable battery's design. The battery is also compatible with some Adventure Force Tactical Strike and Dart Zone BallistixOps blasters such as the Quantum, Accelerator, and Velocity; this cross-compatibility is not intentional on Hasbro's part.
