Hello PE1
With “PDoA tag carrier board” I assume you mean the DWM1004-ES board (which is based on the DWM1001-dev carrier board).
The battery connector is a “Leader Wise” S01-SHSMT02AWV0_YS, which seems to be compatible with 2-pin JST SH series connectors. It should be compatible with the JST SHR-02V-S and JST SHR-02V-S-B cable housings and as @DecaLeo mentioned with the 2-pin JST SR/SZ series connectors.
