Motor
The following are some examples of meter connections. Many other 
arrangements and uses are possible
Battery on SOURCE side, Electronic Speed Controller (ESC) and 
motor on LOAD side, with ESC on, the meter shows the current into the 
motor, voltage and power at the battery and accumulates the charge 
(Ah) while the motor is running.
With a battery charger on the SOURCE side and battery pack on the 
LOAD side, the meter shows the charging current into the battery, the 
voltage and charging power at the battery and accumulates the charge 
(Ah) into the battery.

Battery Discharging
When the battery is discharged, the meter indicates the total charge
(Ah) the battery delivered to the load as well as current, voltage and
discharging power.
