Enhanced Battery Cap for Steiner MPS/MPS-C

Introducing the Shadow Strategic Enhanced Battery Cap for the Steiner MPS and MPS-C.

The cap features a stacked battery configuration:

• One battery installed in the active position
• One backup battery stacked above it in an inverted storage position

Machined from 7075-T6 aluminum and finished with Type III hardcoat anodizing, available in Black or Tan.

The Enhanced Battery Cap also features robust exterior knurling for tool-free battery changes and a heavy-duty O-ring to help maintain water resistance.

Pictured are our first functional prototypes, which are currently undergoing testing. The final production version will feature a revised exterior profile and knurling design.

Estimated release: September–October 2026.
