==Safety Instructions & Warnings==

==Overview==

The X-UPS1 is an universal stackable uninterruptible power supply (UPS) shield for most Single-Board Computers (SBC) that uses 12Vdc or 5Vdc. The UPS ensures that in event of power interruption, a battery or any other power source will intervene without any effect on your board.

Our convenient stackable design allows you to connect several UPS modules on your boards to provide long-lasting & higher output power.

Q: What battery is recommended for X-UPS1 shield?

</div>

A: Please use high quality 3.7V 18650 batteries from Samsung 35E 18650 lithium battery, Panasonic NCR18650B, Toshiba, etc. Do not use the battery with built-in protection circuit because it will limit the discharge current.

Q: Can I use a 20V battery to power the X-UPS1?

</div>

A: Actually the DC/DC chipset can withstand 24V and we tested with a lab power supply and it worked. here is the link of the datasheet.

https://www.richtek.com/assets/product_file/RT7259/DS7259-01.pdf

but to be safe, we recommend that using the 12V batteries to power the UPS boards.

</div>

<!--

Q: When stacking multiple X-UPS1 boards, why do they discharge one by one (sequentially) instead of sharing the load evenly? Is this a defect?

</div>

A: This is the intended design logic of the X-UPS1 to ensure system stability and battery safety and is not a defect.

* '''Sequential Discharge:''' Each board has an '''over-discharge protection circuit'''. The primary X-UPS1 board will power the system until it reaches a low-voltage threshold, at which point the next board automatically takes over.

* '''Voltage Priority:''' Due to minor hardware tolerances, the board with the highest voltage naturally bears the load first, preventing power conflicts between packs.

* '''Power Priority:''' When external power is connected, the UPS '''prioritizes external power''' for the system, and all batteries switch to charging mode only.
