Changes

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 raspberry pi NAS 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]] provides enough voltage&current output and AUTO Power on funtion, no extra programmable function.
