1.Introduction
The QK-A016 is a high precision battery monitor and can be used for boats, campers, caravans and
other devices using a battery. The A016 measures the voltage, current, ampere-hours consumed and
the remaining time at the current rate of discharge. It provides wide range of battery information. The
programmable alarm allows user to setup the capacity/voltage warning buzzer.
The A016 is compatible with most types of batteries in the market including: lithium batteries, lithium
iron phosphate batteries，lead-acid batteries and nickel-metal hydride batteries.
The A016 outputs the standard NMEA 0183 format messages so the current, voltage and capacity
information can be combined with the NMEA 0183 system on the boat and shown on the supported
Apps.
2.Why a battery should be monitored?
Batteries can be ruined by excessive discharge. They may also be damaged by under-charging. This
may result in the battery performance being less than what is expected. Operating the battery without
good metering is like running a car without any gauges.
Apart from offering an accurate state of charge indication, the battery monitor can also help users how
to get the best service life out of the battery. The service life of battery could be negatively affected by
excessive deep discharging, under- or overcharging, excessive charge- or discharge currents and/or
high temperatures. Users can detect such abuse easily through the display monitor of the A016.
Ultimately the longevity of the battery can be extended which will result in long term savings.
3.Connections and Installation
Before starting the installation, ensure that no metal tool can cause a short circuit. Removing all
jewellery such as rings or necklaces prior to any electrical work is considered best practice. If you
believe you may not be sufficiently skilled to undertake this installation safely, please seek the
assistance of a installers/electricians who are aware of regulations for working with batteries.
Please strictly follow the orders of connections given below.
Use a fuse of the correct value as shown in the following diagram.

1. Determine a mounting location and mount the shunt. The shunt should be installed in a dry and
clean place.
2. Remove all loads and charging sources from the battery before any other steps are taken. This
is often accomplished by turning off a battery switch. If there are loads or chargers directly
attached to the battery, they should be disconnected as well.
3. Serial connect the shunt and the negative terminal of the battery (the blue wires shown on the
wiring drawing).
4. Connect B+ of the shunt to the positive terminal of the battery with a AGW22/18 wire (0.3 to
0.8mm²).
5. Connect the positive load to the positive terminal of the battery (Using a fuse is highly
recommended).
6. Connect the positive charger terminal to the positive terminal of the battery.
7. Connect the display with the shunt with the shielded wire.
8. Double check all the connections with the above diagram before turning on the battery switch.
At this point the display will power up, and be operational in a few seconds.
A016’s display comes with a buckled enclosure. A 57*94mm’s rectangular slot need to be cut for
fitting
4.Display and Control panel
The display shows the state-of-charge on the screen. The following image provides what the
displayed values indicate:

Remaining capacity percentage: This shows the percentage of the actual full-charge capacity of the
battery. 0% indicates empty while 100% means full.
Remaining capacity in Amp-hours: The remaining capacity of the battery is indicated in Amp-hours.
Real voltage: Displays of the real voltage level of the battery. Voltage helps assess approximate
state-of-charge and to check for proper charging.
Real current: The current display informs of the current load or charge of the battery. The display
shows the instantaneously measured current rate flowing out of the battery. If the current flows into
the battery, the display will show a positive current value. If the current flows out of the battery, it is
negative, and the value will be shown with a preceding negative symbol (i.e -4.0).
Real power: This shows the power rate being consumed while discharging or supplied while
charging.
Time-to-go: Shows an estimate of how long the battery will sustain a load. Indicates the time
remaining until battery is completely discharged when the battery is discharging. The remaining time
will be calculated from the residual capacity and the real current.
Battery symbol: When the battery is being charged it will cycle to show it is filling. When the battery
is full the symbol will be shaded.
5.Setting up
5.1. Setup battery monitor parameters
The first time you use your A016, you will need to set the battery to its starting point at either empty or
full capacity to start the monitoring process.
Quark-elec recommend starting at full (after the battery has been fully charged) unless you are unsure
of the capacity of the battery. In this case the capacity (CAP) and High voltage (HIGH V) need to be
setup. The capacity can be found on the specifications of the battery, this should normally be listed on
the battery. The high voltage can be read from the screen after fully charged.
If you are unsure of the battery capacity, then you can start with the battery fully depleted (empty).
Check the voltage shown on the screen and set this as the low voltage (LOW V). Then set the monitor
to its highest capacity (e.g. 999Ah). Afterwards please charge the battery fully and record the capacity
when charging is complete. Enter the Ah reading for capacity (CAP).

You can also setup the alarm level to receive audible alerts. When the state-of-charge capacity has
fallen below the set value, the percentage and battery symbol will flash, and the buzzer will be begin
beeping every 10 seconds.
5.2. Setup process
1. Press and hold the OK key on the faceplate until the set-up screen appears. This will show the
four parameters needed to be entered.
2. Press the up(▲) or down(▼) keys to move the cursor to the setting you would like to change.
3. Press the OK key to select the parameters for setting.
4. Press the up or down arrow keys again to select the proper value applied.
5. Press the OK key to save your settings and then press left(◄) key to exit the current settings.
6. Press the left(◄) key again, the display will exit the set-up screen and back to the normal
working screen.
•Setup High V or LOW V only, don’t set the both value unless you clearly know the voltage
characteristics of the battery.
5.3. Backlight
The backlight can be switched OFF or ON to save energy. When the display works in the normal
screen mode (not setting-up), press and hold left (◄) key will switch the backlight between ON and
OFF.
The backlight will flash during charge mode and light solid on during discharge mode.
5.4. Sleep mode in low power
When the battery current is less than the backlight turn-on current(50mA), the A016 will enter a sleep
mode. Pressing any key can wake up A016 and turn on the display showing for 10 seconds.
The A016 will go back to the normal work mode once the battery current is higher than the backlight
turn-on current.
6.NMEA 0183 output
The A016 outputs the real time voltage, current, and capacity (in percent) via the NMEA 0183 output.
This raw data can be monitored using any serial port monitor software or apps on mobile devices.
Alternatively, apps such as OceanCross can be used to view the end user information.

When the SOC falls below 30% the risk of damaging the battery is increased. Therefore, we advise to
always keep the SOC above 50% to optimize the life cycles of the battery.
