The X12-A1 V1.0 is a 4-cell parallel 18650 stackable battery holder designed to accommodate expand the backup power of UPS HAT systems. It uses four 18650 batteriesin parallel, providing plug-and-play capacity expansion for compatible UPS HAT systems such as the X1209 (top-mount) and X1203 (bottom-mount). Each battery is protected by a resettable has an independent ultra-low resistance resettable fuse to effectively prevent over-discharge. It features risks; the four parallel XH2.54 connectors for easy integration with UPS HAT models such as the X1209 interfaces support convenient connection and X1203multi-stand stacking, and supports a stackable design, allowing for flexibly increasing the total power capacity expansion through multiple basesas needed.
