Our original intention of designing X708 is to match with NAS shell (such as [[X829-C1]], [[X857-C1 Case |C3]] or [[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; ===Safety Instructions and Warnings===You must read these safety instructions and warnings before charging your batteries. * <span style="color:red;">Lithium Polymer and Li-ion batteries are volatile.

===X708 V1.2(off-production)===Update:* Remove the ASD function but you can achieve this function through software programming. Please refer to [[U100X708-Software]] if you want a cheap version* New added GPIO16 to control fan speed, HIGH=>fast fan speed, LOW=>slow fan speed; refer to [[U100X708-Hardware]] provides enough * Added voltage&current output and AUTO Power on funtion, no extra programmable function.surge protection circuit

# Excellent UPS function such as Power Loss Detection(PLD), Automatic Safe Shutdown(ASD), Auto Power On(AON) etc., '''DC 5V Max. 8A 6A output''';

==What you may care aboutWorking principle==A: I want The GPIO13 is used to a NAS storage solutioncontrol the power button, Does X708 support? Q: We have received many feedbacks It goes high for 3 seconds that want to support UPS, so we design means the X708 base on [[X728]], we separated the battery holder from the UPS expansion board to save space, thus X857-C1(metal case power switch is pressed and held for mSata NAS solution), X829-C1 (metal case for dual 23 seconds.5" sata NAS solution), X825-C7(metal case for singel 2.5" sata NAS solution) can hold then the all accessories needed for X708 will issue a pulse to inform the complete NAS solution. There metal case can hold 2 cell 18650 battery holder.  A: I want system to use a larger capacity or more 18650 batteriesimplement safeshutdown via GPIO5, what should I do? Q: In this case and will monitor the GPIO12, the inside space of metal case once shutdown process is definitely not enoughimplemented, but you can place GPIO 12 will go to low and will be recognized by the battery outside X708, then the metal case. We have reserved a hole at the back of the metal casing X708 will wait for you to connect to the battery cable7-8seconds then fully cut off power.  A: Is there a corresponding UPS NAS solution for 3.5-inch hard drives?

Q: Sorry, There is no UPS NAS solution Firstly you have to get the script for 3power management well installed and run at boot.5-inch hard drive because You can use the onboard power switch to verify , press and hold for 3.5-inch hdd request 12V voltageseconds, so we have no plans to support this demand for the time beingblue LED will flash slowly and the shutdown is going then all LEDs will be off. BUT once this works, then you can refer to [[X835]]//[[X832]], and they can solve some of your needs, they need external power supplyuse the GPIO13 control.

Q3A: How * Pls use high quality batteries from PANPASONIC, Toshiba, etc.* Lithium battery need to restart meet following 2 conditions: 1. Working voltage: 3.6V-3.7V; 2. Maximum voltage after full: 4.2V* Do not use the pi board when AC Power supply is connected?battery with built-in protection circuit[[File:18650_battery_size-2.jpg|400px]]

A'''Q2: Please enable What type connector to request for lithium battery?'AUTO POWER ON' or 'AUTO ON' function if * A: X708 provides two type battery connectors: PH2.0-2P and XH2.54-2P, you want restart when can connect two battery at the same time, BUT please use the same model batteries, also please pay attention that the polarity of the AC Power supply XH2.54 and PH2.0 connectors is reapplieddifferent.

'''Q4: Which lithium battery can be usedHow to restart the pi board when AC Power supply is connected?'''* A: Please enable 'AUTO POWER ON' or 'AUTO ON' function if you want restart when the AC Power supply is reapplied.

'''Q6: About auto shutdown, found your board will auto shutdown.'''* A: Please check if enable the ASD function (shorted the ASD header), if you enable the ASD function, please sure your oeration is right: first, place the battery into the battery holder, insert the jumper to meet the following 2 conditionsASD header <span style="color:red;">after 3 second</span>,this is very important!!

1. Working voltage'''Q7: Does the X708 support to use without any battery installed?'''* A: 3.6V-3Yes, it is ok to use the X708 without battery, but please note that do not use low quality power supply.7V

2. Maximum voltage after full'''Q8: 4.2VWhy the X708 does not work normally?'''* A: Please make sure you have install the script before use, please refer to [[X708-Software]]

Q5'''Q10: What type connector Does the X708 support to request for lithium batteryuse the latching switch?'''* A:No, the X708 does not support to connect latching switch, only support momentary switch.

A'''Q11: What is the fan type of the X708 provides two type battery connectors?'''* A: It is szie 3010 cooling fan with PH2.0-2P and XH2.54-2P, you can connect two battery at the same time, BUT please use the same model batteries, also please pay attention that the polarity of the XH2.54 and PH2.0 connectors is differentconnector.

Q6'''Q13: About auto shutdownWhy does the X708 power off automatically?'''* A: Please use 3.7V lithium polymer battery without protection board, or battery with enough discharge capacity, found your board or the X708 will auto shutdownpower off automatically when use with high load.
