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.
