BR-28 Series Battery Magazine

The Ketsurui Zaibatsu BR-28 is a rechargeable battery magazine for Star Army of Yamatai energy pistol sidearms. It was originally made in YE 28 as part of the Nekovalkyrja Service Pistol, Type 28 and is now used in several other weapons.


The battery slides into the back of the NSP and has metal contacts on one end. The other end features a small electronic display to show the amount of pulses remaining based on its current energy levels. A fully charged BR-28 series battery holds enough power for 50 to 51 standard energy blasts.

The batteries have a usable life of about 10 years before the internal parts need to be replaced, so the earliest ones are starting to go bad.


The original model had a sharp end that was problematic and was quickly replaced by the BR-28A which as has a more rounded user-facing end.
