* <span style="color:red;">Lithium Polymer and Li-ion batteries are volatile. Failure to read and follow the below instructions may result in fire, personal injury and damage to property if charged or used improperly.
* <span style="color:red;">Never make wrong polarity connection when charging and discharging battery packs. Always double check polarity of battery's connector to make sure "+" to "+" and "-" to "-".
* <span style="color:red;">Do not mix and use old batteries and new batteries, or batteries with different brand names.
* <span style="color:red;">Lithium batteries has it's cycle life, please replace old battery with new one when it reaches it's service life or when it is two year old, whichever comes first.
* <span style="color:red;">When charging Battery Pack, please put battery in a fire proof container. Please don't leave the X728 on the wood material or carpet and unattended.

Q: Why Press '''Ctrl-X''' to exit nano (the X728 V1editor).3 remove the ASD function?
A'''Step 2''': Because the ASD jumper will generate some issues(Optional, so we remove the ASD jumper, but now if you can achieve ASD function by software. Read the voltage through I2C, use USB peripherals and then decide whether to shut down.require higher current)
Q1: Why X728 V1'''Reboot''' your Raspberry Pi 5 to make the change take effect.2 automatically shuts down?
A'''Note: 1. X728 V1.2 will automatic safe shutdown when battery voltage is low than 3.0V''' If you are using other OS like Ubuntu, please charge in time;flash '''Raspberry Pi OS''' first, and then re-flash other OS such as Ubuntu etc after completing the above settings.</div></div>

Q: Why the X728 V1.3 remove the ASD function?
</div>
<div class="mw-collapsible-content">
A: Because the ASD jumper will generate some issues, so we remove the ASD jumper, but now you can achieve ASD function by software. Read the voltage through I2C, and then decide whether to shut down.

A: Please enable 'AUTO POWER ON' or 'AUTO ON' function if you want restart when the AC Power supply is reapplied.
</div>
</div>
<div class="toccolours mw-collapsible mw-collapsed">Q4: About auto shutdown, found your board auto shutdown. A: Please check if enable the ASD function (shorted the ASD header), if you enable the ASD function, please make sure your operation is right: first, place the battery into the battery holder, insert the jumper to ASD header <span div style="colorfont-weight:redbold;line-height:1.0;">after 3 seconds</span>,this is very important!! Q5:Is the recharge threshold and terminal battery voltage adjustable? I want to keep the batteries between 80% and 20% A: Sorry, this is not support. Q6Q: Which GPIO is used to power the X728-A1 cooling fan?</div><div class="mw-collapsible-content">
A: The X728-A1 does not occupy the GPIO, it use the PIN 2,4 to provide the power.

Q: What will lead to the X728 board be burnt out?
</div>
<div class="mw-collapsible-content">
A: Please make sure the polarity of battery is "+" to "+" and "-" to "-" and match with the "+" "-" mark on battery holder. The battery protection chip IC will be over-current, heat and then burnt if one or two of the batteries are connected reversely. PS: the X728 board will not be burnt immediately if one or two of the batteries are connected reversely.
