The lithium battery is connected to the BAT+ and BAT- pads on the right-hand side. If you are using the board with the protection circuit, you can connect the output to the OUT+ and OUT- pads. Connect the output wires to the BAT+ and BAT- if your board does not have a protection circuit.
You have the option to power the board via a USB cable or by attaching an external power source to the IN+ and IN- pads on the left-hand side. The lithium battery is connected to the BAT+ and BAT- pads on the right-hand side. If you are using the board with the protection circuit, you can connect the output to the OUT+ and OUT- pads.
Connect the output wires to the BAT+ and BAT- if your board does not have a protection circuit. The charging current is set to 1 A. This setting is fine for 18650 and similar style lithium batteries but is too high for lower capacity lithium polymer batteries. You can lower the charging current by changing the R3 resistor.
All this means that you can employ unprotected Lithium cells such as standard 18650 batteries in combination with common charge modules. Off-the-shelf battery modules are a good way to secure a project that uses batteries against common faults that might occur while charging or discharging a Lithium battery.
