If you open the battery compartment, you see the connector on the<br>
bottom, starting from left:<br>
<br>
- / TEMP / + (SIM Connector)<br>
<br>
Just attaching a charger doesn't work. But you can can basically attach<br>
any charged 3.7 Volts LiIon/LiPo battery, the pin between - and + isn't<br>
needed for operation (charging excluded).<br>
