Nerf RapidStrike Battery mod

thingiverse

My initial plan was to swap out the standard battery box with something that can hold a 6-cell 7.2V NiMH/NiCd battery pack, commonly used in RC cars, but it was too small. I remade intofocus's box, which I really liked because of the way the connector is designed, incorporating the front lid by removing the bottom screw-hole for easier printing and not needing the third screw, still I had a tough time fitting the NiMH pack into the box due to the Tamiya connector causing problems. Not wanting to disappoint my son, I opted for a quick fix, which was connecting a tamiya contra plug to the battery box so there's no battery inside now. I insulated the copper wires with PVC tape, drilled two small holes for the wires, and added a small knot to prevent them from being accidentally yanked out. The battery itself is mounted externally using a clip that can slide onto the side picatinny rail of the Nerf blaster. The NiMH pack is secured on the clip with some velcro. Although the design needs room for improvement, my son is happy now. Originally run on 6V (4x 1.5V C-Cell), the blaster has noticeable extra power and better battery life without over-stressing the motors too much. The battery sidepack with exposed wires looks kinda futuristic and cool. Use at your own discretion; I wouldn't recommend this setup for small children. The Nerf logo is a trademark of Hasbro.
