8.2.2 FlexPower with Integrated Battery

A few FlexPower devices operate using a 3.6V lithium D cell battery integrated into the housing.

These integrated battery devices:

• Operate only from the battery and cannot use an external power supply,

• Are limited in the available I/O because of the limited connectivity, and

• Can only be powered from the integrated battery.

8.2.3 FlexPower

Solar Supply

Banner’s FlexPower Solar Supply Assembly can be used to power up to two radio devices, including a FlexPower Node, a

FlexPower Gateway, or a data radio.

When used with a FlexPower Node and sensors, the Solar Assembly

supplies enough power to run most sensors at higher sample and

report rates than a single battery can reasonably support.

Rechargeable batteries power the devices while the solar panel

recharges the batteries.
