+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 class="mw-collapsible-content">
+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 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.
