Can the XIAO ESP32C3 battery management handle LiFePO4?

XIAO_ESP32C3 uses a charge controller that I believe is MCP73831. Please check the datasheet. Also, the following link may be helpful.

Charging characteristics of XIAO_nRF52840 and XIAO_ESP32C3

XIAO_nRF52840 and XIAO_ESP32C3 have a built-in charging function, but since the circuit diagram was not disclosed, I assumed that they have the same circuit. I was curious and measured the charging characteristics. They are completely different, XIAO_nRF52840’s charging current can be set to 50mA or 100mA by firmware, but XIAO_ESP32C3’s is fixed and very large at 370mA, so I need to be very careful when using small capacity batteries.
