The battery is the VE SLI-50 with a 48Wh capacity, which
is used to power the TM-RX. It can be used in either
orientation to simplify battery changes.
The battery incorporates a gas gauge circuit which
accurately measures the power in and out of the cell,
providing an accurate time remaining indicator, both
under charge and discharge conditions.
To check the power remaining in the battery simply press
the indicator button to get the power level to display on
the LED power level meter for several seconds.
