 ==Overview==
-The X12-A1 V1.0 is a 4-cell parallel 18650 battery holder designed to accommodate four 18650 batteries. Each battery is protected by a resettable ultra-low resistance fuse to prevent over-discharge. It features four XH2.54 connectors for easy integration with UPS HAT models such as the X1209 and X1203, and supports a stackable design, allowing for capacity expansion through multiple bases.
+The X12-A1 V1.0 is a stackable battery holder designed to expand the backup power of UPS HAT systems. It uses four 18650 batteries in parallel, providing plug-and-play capacity expansion for compatible UPS HAT systems such as the X1209 (top-mount) and X1203 (bottom-mount). Each battery has an independent ultra-low resistance resettable fuse to effectively prevent over-discharge risks; the four parallel XH2.54 interfaces support convenient connection and multi-stand stacking, flexibly increasing the total power capacity as needed.
