Hi Dialog Semiconductor,
I am planning to use Polymer Lithium-Ion Battery with 3.7 V to power up the DA14531 module for buck mode operation. Will it be ok? or do I have to stay within the 3.3 V limit?

Hi robelhk,
Thanks for your question. Please see DA14531 Module Datasheet and table Table 2: Absolute Maximum Ratings. The max battery supply on the VBAT is up to 3.6V. Acco4rdin to Table 3: Recommended Operating Conditions, the recommended voltage on the VBAT is 3.3V.
Thanks, PM_Dialog
We have been using this for several weeks now and it seems to be going nicely.

You mean 3.7 V battery? Any specific battery you are using?
Hi robelhk,
According to the DA14531MOD datasheet the max supply on the VBAT is 3.6V – please see me previous comment.
Thanks, PM_Dialog
