Q: 1. Does B&H sell a dual battery pouch that will fit two DMW-BLJ31 batteries? Ruggard battery pouch (B&H # RUBPR2SLRB) is too small

A: The size of the Watson DMW-BLJ31 Lithium-Ion Battery Pack (7.4V, 3500mAh, 25.9Wh) poses a problem for our dual-battery pouches such as the Ruggard Battery Pouch for 2 DSLR Batteries (Black), B&H # RUBPR2SLRB.
