Product Introduction
DROK Bidirectional Voltage Current Meter (VAH9030H) is a new
type of voltage amp meter that can measure voltage, current,
charge-discharge capacity, time, power and other electric
parameters. It can also set parameters for over-voltage
protection, under-voltage protection, over-current protection,
over-charging capacity protection and over-time protection.
The non-contact Hall sensor is used to detect the current,
which is safe and convenient. Moreover, this meter adopts
color LCD to display data, which is a more comprehensive
and humanized design.

Power Expansion Board Wiring
Pictures below show the circuits in the discharging mode.
For charging, you just need to change the load to the charger
and there is no need for changing the circuit. If the current
enters and flows out from the front and back of the transformer,
the remaining battery capacity decreases, and conversely, the
remaining battery capacity increases.
