I have received a new M5StickC, and receive the error "Error 22: Bat Val Error, Check Hardware" when plugged into USB. The screen goes dark and the device powers off when unplugged from USB. I have tried leaving it to charging for hours as well as trying to BAT to GND trick, but to no avail. How should I proceed?</p>
<p dir="auto">Thanks</p>

I'm a seller in Thailand and now I have M5StickC about 10 Pcs.<br />
And all have the same problem is battery can't be charged and display error message "Error 22"<br />
After I've charged for all-day it still showing an error message.<br />
Or is it possible to use it while connecting the USB cable ? (don't mind about the battery)<br />
Thank You in Advance.</p>

<p dir="auto">this error message seems to be part of the factory test. I am afraid the battery in your M5StackC got depleted so much that the voltage reading is below 3 volts and therefore the battery is considered 'dead'.</p>
<p dir="auto">I suggest you contact the shop and ask for a replacement.</p>
<p dir="auto">Felix</p>
<p dir="auto">From <code>FactoryTest.ino</code></p>
<pre><code>    float VBat = M5.Axp.GetBatVoltage();
    if ((VBat &lt; 3.0) || (VBat &gt; 4.4))
    {
        ErrorMeg(0x22, "Bat Vol error ");
        return false;
    }
</code></pre>
