This gauge comes pre-programmed with three selectable chemistry profiles, each identified by a unique Chemistry ID (ChemID):​\n - ChemID 0x3230: Corresponds to a 4.2V lithium-ion cell.​\n - ChemID 0x1202: Corresponds to a 4.35V lithium-ion cell.​\n - ChemID 0x3142: Corresponds to a 4.4V lithium-ion cell.​\n\nThese ChemIDs are defined in the Zephyr project's sensor bindings for the BQ27427:​\n - BQ27427_CHEM_ID_A: 0x3230​\n - BQ27427_CHEM_ID_B: 0x1202​\n - BQ27427_CHEM_ID_C: 0x3142​\n\nWhen configuring the BQ27427 for your application, it's essential to select the ChemID that matches the nominal voltage of your lithium-ion battery to ensure accurate fuel gauging. For more detailed information, you can refer to the BQ27427 product page on Texas Instruments' website. ​","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Farkhipenko%2Fbq27427-arduino","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Farkhipenko%2Fbq27427-arduino","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Farkhipenko%2Fbq27427-arduino/lists"}
