Hi,
The product description mentions it having a JST GH 1.25mm connection.
However, the connectors do not look like the connectors from the JST GH spec sheet. https://www.jst-mfg.com/product/pdf/eng/eGH.pdf
Instead, they look like Molex Picoblade connectors (with the side channels).
Can you please confirm the exact part number for the battery connectors? (both the SMT part on the board, and corresponding plug part)?
