SAFETY INSTRUCTIONS
WARNING
To avoid any personal injury, please read the safety instructions below.
This battery charger is not intended for use by children or inrm persons without supervision.
FOR AUTOMOTIVE AND RECREATIONAL VEHICLE 12V DEEP CYCLE BATTERY USE ONLY.
NOT TO BE USED WITH DRY CELL BATTERIES.
During the charging process, do not use a naked ame near a battery. Batteries generate gasses
during the charging process that may explode
Never smoke or light cigarettes near a battery
Do not place tools on top of a battery or allow tools to fall on the battery to prevent the chance
of a short circuit and sparks
Always wear eye protection when charging battery
Ensure charging and testing is conducted in a well-ventilated area
Inadequate ventilation may over-heat the charger and cause inecient operation
The ACID / FLUID within a battery is highly corrosive and poisonous. It can produce ammable
and toxic gases when recharged and will explode if ignited. When working with batteries, always
wear eye protection, remove jewellery and ensure the area is well ventilated. If spilt – it will cause
severe burning to eyes, skin, clothing, and damage paintwork and corrode many metals. Ensure
that power is disconnected from any appliance in the vicinity of the spill and immediately wash
any area that has been aected with water. Seek medical attention.
The warnings, cautions and instructions detailed in this instruction manual cannot cover all
possible conditions and situations that may occur. Common sense and caution are factors which
cannot be built into this product and must be supplied by the operator.

INSTALLATION OPTIONS / INSTRUCTIONS
Installing the Charger
This unit is supplied with 50 Amp Anderson style connectors already connected to the battery
charging output, the solar input and the battery input leads, ready to plug and play. More wiring
and connectors will be required to connect these to your vehicle/panels etc. if they are not
already tted.
Any existing or additional cables used in the installation of this product needs to be suitable for
the current and distance required. Matson recommends the use of 10mm2cable for this purpose
as a minimum.

INSTALLATION OPTIONS / INSTRUCTIONS
Choose a location to install the charger, ideally somewhere cool and dry for best performance.
Under the bonnet will work, but try and maximise airow around the charger, without too much
water. Excessive heat will lower the charger output. It is also advisable to place the charger as
close to the auxiliary battery as possible for best charging performance
Ensure the charger is securely mounted. This can be in any orientation, inverted, vertical or
horizontal, as required. If the unit is being installed in a harsh vibration area, like an engine bay,
consider mounting over small rubber or high density foam pads
Measure the distance from the starting battery to the charger; the distance between the charger
and the auxiliary battery; the distance between the solar panel output and the charger. Source
cable and terminations to suit. Matson recommends a minimum 10mm2 good quality twin-core
cable for this application.
Ensure ALL cabling meets specication and will not be exposed to excessive heat / moving parts
or abrasion
Connect the auxiliary battery to the charger – make sure polarity (+ & -) are correct
Connect the solar panels to the charger – make sure polarity (+ & -) are correct
Connect the main battery to the charger - make sure polarity (+ & -) are correct
It is recommended that a 25 Amp circuit breaker or fuse be installed between the main battery
and the charger, but is not essential
Make sure all connections are tight
Low or Variable Voltage Alternators
If the vehicle is tted with a low voltage or variable voltage alternator, the ignition sensing wire
will need to be connected. This will allow the charger to continue to operate when it senses much
lower voltages (as low as 10.8V) from the main battery, because it can sense the engine running.
Using 2mm automotive cable, connect the small ignition cable from the back of the charger to
an ignition power source. This can be complicated and may require the assistance of an auto
electrician or qualied installer. Once the charger senses ignition power it will start charging.

1. DC Battery Input
Once correctly installed the MA21DCS needs the battery chemistry to be selected, then it will
operate automatically with no further input.
Start the vehicle and let it idle
The charger will recognise that there is charge going into the main starting battery
Once the main starting battery reaches 13.0V (11.5V if ignition sensor is installed), the MA21DCS
will begin charging the auxiliary battery
Change the battery chemistry setting to suit your application. The default setting is Lead Acid.
Once selected, the charger will remember this as the new default setting, you do not need to
change the setting again
The charger will continue to operate until the vehicle is switched o (Ignition sensor connected)
and/or the main starting battery drops to 12.4V
2. Solar Input
If a solar panel input is connected to the MA21DCS, it will automatically accept power from the
panels once the engine has stopped running and the main battery has dropped to 12.4V.
Minimum solar input voltage is 13.5V, maximum is 25V. No regulator is required between the
charger and the panels if the panel output voltage is within those parameters.

Deep cycle batteries
It is expected that this charger will be used to charge a deep cycle type auxiliary battery.
Deep cycle batteries are designed to provide battery power to run items like fridges and lighting in
caravans and campers.
It is generally accepted that the life of a deep cycle battery can be extended if it is not discharged
below 50% of its full capacity. A fully charged 100 amp battery in good condition should oer
50 amp hours of power without impacting on its normal life expectancy.
Your average compressor style fridge uses up to 5 amps. Over a 24 hour period it should use
approximately 30 amp hours. Therefore if the 100AH battery is operating only the fridge (and
receives no additional charge) it ideally will require recharging after 48 hours.
To replenish these 60 amp hours using a 20 amp DC-DC charger will require at least 4 hours of
driving. The last 10-20% of battery charging is slow, the closer it gets to 100%, the slower it is.
Undercharging a battery and discharging to below 50% can severely impact on life expectancy of
most deep cycle batteries.
Approximate state-of-charge Average specic gravity Open circuit voltage 12V
100% 1.265 12.65
75% 1.225 12.45
50% 1.190 12.24
25% 1.155 12.06
0% 1.120 11.89
The readings are taken at room temperature of 26°C (78°F); the battery had rested for 24 hours after
charge or discharge.
Voltage reading and specific gravity of electrolyte (lead acid batteries) can give an indication of your
battery’s state of charge.
