For Version UPS PIco HV3.0 Stack/TopEnd the charging
current is fixed to 300 mA.
For Version UPS PIco HV3.0 Plus the charging current is
dynamically changed based on powering conditions on
micro USB powering input or External Powering Input.
The charging current on that version is from 100 mA
–
800 mA. With maximum of the system to be 1200 mA
(will be activated in the future).
