Ready for GFX 100S and X-series

This two-pack supplies 7.2 V lithium-ion cells rated at 2040 mAh each, matching the Fujifilm NP-W235 form factor. They fit the GFX 100S, GFX 50S II, X-T4, X-T5, X-H2 and X-H2S bodies that accept the original battery. Photographers who need spare power for long sessions can carry both units without changing chargers.

Built-in protection and UL1642 compliance

Each cell includes over-charge, over-discharge, over-voltage, over-current and over-heating circuits and meets UL1642 and CE safety marks. The pack slips into the existing Fujifilm BC-W235 charger, so day-to-day workflow stays the same — insert, charge, shoot. No extra cables or docks are required.

Replaces single OEM cells for extended shooting

Swapping one factory battery for this pair roughly doubles available capacity at 14.7 Wh per unit, useful for video, time-lapse or multi-day trips. The upgrade makes sense when a single charge no longer covers a full day; it is not suited for cameras such as the GFX 100 or GFX 50S that use a different battery format.
