The X12-A1 V1.0 is a stackable battery rack designed to expand the backup power of UPS HAT systems. It uses a parallel configuration of four 18650 batteries, providing plug-and-play battery capacity expansion for compatible UPS HAT systems such as the [[X1209 ]] (top-mounted) and [[X1203 ]] (bottom-mounted). Each battery has an independent ultra-low resistance resettable fuse to effectively prevent over-discharge risks; the four parallel XH2.54 connectors support convenient connection and multi-stand stacking, allowing for flexible increases in total power capacity as needed.
