SupTronics X12-A1 4-Cell Battery Holder for X1209/X1203

The SupTronics X12-A1 is a 4-cell parallel 18650 battery holder designed for use with compatible UPS HATs such as the X1209 and X1203. It supports up to four 18650 batteries (batteries not included) connected in parallel, making it suitable for applications requiring increased battery capacity and longer runtimes.

Each battery slot includes a resettable ultra-low-resistance fuse to help protect against over-discharge, improving both safety and reliability. The board also features four XH2.54 connectors for simple integration with supported UPS HAT models, including top-mount support for the X1209 and bottom-mount support for the X1203.

Its stackable design allows multiple holders to be connected together for further capacity expansion, making it a flexible option for larger power setups.

Please note: This is specifically designed to work with the X1209 and X1203!  Raspberry Pi and batteries are not included.
