I am working on a project which requires running an Electron off of a 12V lithium battery pack through the Vin pin. So far, with the PCB i have created, the circuitry works fine when running off of a separate 12V supply, but when running off of the 12V lithium battery, the Electron’s PMIC circuitry fails and stops working. The electron will run off of the included 3.7V lithium battery, but will no longer run off of the Vin pin or USB port.
During testing, the voltage on the battery pack was 13.3V. I understand this is higher than Particle’s recommended input voltage, but according to the PMIC’s datasheet, falls well within the maximum voltage range.
Has anyone else had success running an Electron off of a similar battery or similar issues with the PMIC circuitry?
