The battery voltage can be configurable by changing single resistor (R9) to change the battery voltage from 4.2V/4.35V/4.4V/4.5V. (default is 4.2V)
Choose R9 Resistor as –
[Both 0603 / 0805 will work]
10K – 4.2V [Default]
15K – 4.35V
5.6K – 4.4V
3K – 4.5V

Maximum battery capacity supported is 30000mAH. Single resistor change (R8) can configure this module board as 10000mAH / 20000mAH/30000mAH. (default is 20000mAH)

Choose R8 Resistor as –
[Both 0603 / 0805 will work]
20K – 10000mAH
36K – 20000mAH [Default]
53K – 30000mAH

How to set battery capacity:
R8 resistor sets the resistance for the battery capacity. The resistance value is calculated as follows
Resistance value = (total battery capacity mAh + 2000) * 5 / 3
For example, the battery capacity is 30000mAh.
Resistance of R8 = (30000 = 2000) * 5/3 = 53333Ω.
A resistor of 53K can be used instead.
The resistance value of R8 resistor can be replaced using an approximate value. It doesn’t have to be exact
