Hello!
I need to make long term recordings (at least 72 hours) using Cyton board. I tried a powerbank, but it turns off after a couple of hours, probably due to a very low current request from the board. Any tips?
Cyton draws about 50 milliamps of current from the 3.7V lithium cell used. Divide the capacity of the cell in mAh (milliamp hours) by 50 to determine run time length in hours. Adafruit has (or used to stock) a wide variety of cell sizes. If you go with another supplier, please be sure that the plug polarity matches that used by OpenBCI and Adafruit. A minority of suppliers differ. Adafruit also has usb chargers for the cells.
