HATs and other add-ons • Stacking HATs: Uputronics GPS and Waveshare Li-polymer Battery HAT possible?

Hi,

Using on a Pi 4B the GPS works fine.
Now I want to expand this with the Waveshare Li-polymer Battery HAT.
Is this possible? When can HATs be stacked?

From the Uputronics manual:
Pin Raspberry Pi Name Board Purpose
01 3.3V DC Power 3.3V DC Power
02/04 5V DC Power 5V DC Power used for super caps
03 GPIO02(SDA1,I2C) GPS/RTC SDA
05 GPIO03(SCL1,I2C) GPS/RTC SCL
08 GPIO14(TXD0) GPS SERIAL RXD
10 GPIO15(RXD0) GPS SERIAL TXD
12 GPIO18 TIME PULSE

Don't know about the Waveshare Li-polymer Battery HAT.
