|
The alert threshold that sets the state of charge level (%) where an interrupt is generated.
|
|
If skipped the power up default value of 4 (%) will be used.

maxim,double-soc:
|
|
type: boolean
|
|
description: |
|
|
Certain devices return double the capacity.
|
|
Specify this to divide the reported value in 2 and thus normalize it.
|
|
SoC == State of Charge == Capacity.
