==Overview==

Our original intention of designing X708 is to match with NAS shell (such as [[X829-C1]], [[X857-C1 Case |X857-C1]], [[X825-C2 Case |X825-C7]]) to provide a storage solution with UPS function. In order to save space, '''we must separate the battery''' from the UPS expansion board when designing . This is also the biggest difference between X708 and X728;

Please refer to [[U100]] if you want a cheap version, [[U100]] only provide enough current output and AUTO Power on funtion, no extra programmable function.

The X708 is an advanced uninterruptible power supply expansion board for all current models of the Raspberry Pi using a 40 pin header. It provides 5.1V Max. 8000mA Power Backup for even the most demanding Raspberry Pi set ups, intelligent and safe power management, safe shutdown，AC power loss/ power adapter failure detection , auto power-on, full poweroff from software, and a cooling fan.
