Overview

The X12-A1 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.

Features

• Parallel Capacity Expansion: Can accommodate four 18650 batteries connected in parallel, directly increasing power supply capacity.

• Independent Protection: Each battery is equipped with an ultra-low internal resistance resettable fuse to prevent over-discharge.

• Plug and Play: Provides four XH2.54 connectors, compatible with specified UPS HATs, requiring no modifications.

• Stacking Design: Supports multiple stacks (requires the X12-A1 stacking kit), flexibly expanding total power capacity.

• Compatible Models: X1209 UPS HAT (top-mounted Raspberry Pi), X1203 UPS HAT (bottom-mounted Raspberry Pi).

• Core Application: The X12-A1 provides a backup battery expansion solution for the aforementioned UPS HATs.
