Both chemistry batteries are available in 2 capacities. Therefore the UPS PIco HV3.0
can be supplied with the following batteries:
•
The standard LiPO battery 450 mAh which comes with the UPS PIco HV3.0
•
The enhanced LiPO battery with capacity 4000 mAh
•
The enhanced LiPO battery with capacity 8000 mAh
•
The enhanced LiFePO4 battery with capacity 4000 mAh
•
The enhanced LiFePO4 battery with capacity 8000 mAh
Batteries with different chemistry offers different unique features, and needs to be
specified on the system setup when changed. The core differences between both
chemistry batteries are listed here below. The battery type setting declare the
chemistry and not the capacity of the battery. Declaration of the battery chemistry is
needed due to different threshold voltages and slightly different charging algorithm.
It is mandatory to have declared a proper battery chemistry for a proper system
functionality. The default battery chemistry is the LiPO and if not changed it is not
needed to change the declaration. Only if the user use the enhanced LiFePO4 batteries
it is need to proceed with changed of the battery chemistry declaration.
