## Description

```text
Instrument to study radiographic imaging of a LiFePO4 battery under charge/discharge. Developed for PaNOSC (EU H2020 GA No. 823852).

Nota Bene: For simpification, this version of the instrument does <strong>NOT</strong> currently react to setting "battery_charge".

Radiography_Lithium_Battery was derived from Radiography_absorbing_edge. by Linda Udby and Peter Willendrup.
