Safety Precautions Prior to Charging Batteries
If necessary to remove a battery from a boat to charge, always remove the grounded terminal from battery
first. Make sure all accessories in the boat are off, as to not cause an arc.
Be sure the area around the charger and the batteries is well ventilated while the batteries are being charged.
Gases can be forcefully blown away using a piece of cardboard or other nometallic material as a fan.
Clean battery terminals with full eye protection to prevent corrosion from coming in contact with eyes.
Add distilled water in each cell until electrolyte reaches levels specified by the battery manufacturer. This
helps purge excessive gases from cells. Do not overfill. For batteries without caps, carefully follow the
manufacturer’s recharging instructions.
Study all manufacturer’s specific precautions, such as removing or not removing cell caps while charging, in
addition to rates of charge.
Extension cords should be industrial grade / heavy duty and grounded. Check extension cord before use for
damage, bent prongs and cuts. Replace if damaged.
Never charge a frozen battery.
Always make your extension cord connection on the charger side first. After connecting the extension cord to
the charger proceed to plug the extension cord to a nearby AC RCD-protected (ground fault circuit protected)
outlet.
Always remove the extension cord from the AC outlet first when charging is completed, followd by unplugging
the charger.

General Overview
The ProSport charger is a fully automatic, electronic multi-stage on-board marine battery charger. It is
prewired for easy installation and is 100% waterproof for fresh and salt water applications.
The ProSport incorporates an extruded aluminium housing with plastic end caps. This design offers improved
durability and heat transfer while comparing it to full plastic case competitive products. The ProSport offers
multi-stage charging which includes a “float” maintenance mode that is safe for long and short term storage.
ProSport can be left on indefinitely without harming or overcharging your batteries.
TM
The ProSport’s DISTRIBUTED-ON-DEMAND multi-stage charging technology will automatically sense and
distribute 100% of the available charging amp output, i.e. 8, 12 or 20 amps (model specific) to any one bank
or combination of all banks. Each battery bank output is fully isolated.
Easy to view LED indicators will provide you with AC power on and charging status. The LED indicators can
be seen from the front and the side of the charger when installed.
The ProSport is available in different models and can be used in 12, 24 and 36 volt configurations (model
specific) without rewiring or switching. Just attach the DC output cable terminals as illustrated in the
installation section of this manual.
With your ProSport plugged in properly, it will automatically and fully charge your batteries while it conditions
and extends the life of your batteries. When you are not at the boat you can leave your charger plugged in to
reduce sulfate buildup allowing your batteries to be fully charged and maintained until your next boat trip.

TM
ProSport’s DISTRIBUTED-ON-DEMAND feature will automatically distribute 100% of ist available charging amps
of 8, 12 or 20 amps (model specific) to any one bank or combination of all battery banks. This feature ensures
all available charging amps are used unlike other 2 and 3 bank chargers with a fixed amp limit per bank.
Note: Above illustration reflects typical battery usage after a day of fishing. Trolling motor batteries are 50%
discharged and not usable. Engine start battery is 90% charged from the engine charging system.

ProSport’s DISTRIBUTED-ON-DEMAND charging technology
ensures that 100% of the available charging amps are fully
utilised. The ProSport charger will distribute ist total
available charging amps to meet the demand of each
battery on-board.
Let’s say your engine start battery only needs 2 amps from
your ProSport PS1212 2-bank charger. No problem,
because the unused 10 amps will be automatically
distributed to the domestic battery bank. A conventional 12
amp charger could only provide a total of 6 amps to the
domestic battery bank, leaving 4 amps of charging capacity
unused.

Competitive conventional chargers typically have an amp
limitation per battery bank. As illustrated, the 12 amp
charger cannot transfer the unused 4 amps not required by
the engine start battery, leaving only a maximum of 6 amps
for the domestic battery bank.
