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? | |||

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. | |||
