I was looking into charging of a 3.6 V lithium ion battery using a solar panel.
The charging voltage needs to be 4.2 V to fully charge the battery.
Does the BQ25504EVM-674 board have the options for generating charging voltage of 4.2 V or higher?

Thank you for the reply. One more query.
So, is changing the resistors the only component I need to change to get the higher voltage?
Is the maximum voltage 5.25 V that we can get changing the resistors?
Thanks.
The VBAT_OV resistors set the maximum charge voltage to prevent over charging.
The VBAT_UV resistors set the minimum voltage to prevent over discharging.
You will need to change both sets of resistors.
5.25V is the maximum voltage.
which type of battery should be used with bq25504EVM?
the UV and OV thresholds donot seem to match any type of batteries out in the market.
