Setting up the controller for different voltages of lithium batteries
It is possible to use the WaterWorld system with different battery configurations. To do this, a setting
on the controller can be modified.
If the plug, with green/black cable and indication “44Vdc,” is connected to the counter plug
on the controller, then the system is suitable for standard voltages. The “cut-off” voltage,
the minimum voltage at which the controller stops working, is then 37 Volts. A warning on
the display appears from 39 Volts.

If the green/black cable is not connected, then the “cut-off” voltage, the minimum voltage at which
the controller stops working, is 42 Volts, and the warning on the display appears at 44 Volts.
WARNING! Many lead-acid batteries go down to a loaded power of 37 Volts.

Setting 1
Suitable for: Full-traction batteries, some AGM, and lithium batteries are suitable for this
setting. Consult your battery supplier for more information.
Setting 2
Suitable for: AGM, semi-traction lead-acid batteries, and various lithium batteries.
WARNING! Improper use of this setting can lead to irreversible damage to the battery
pack. WaterWorld is not responsible for damage caused by deep discharge.
Testing and Commissioning
To check the operation of the system after installation, you can follow the steps below:
•
Check if the batteries are sufficiently charged by measuring the voltage with a multimeter on the
poles of the battery pack. The total voltage should be at least 48 Volts, but around 52 Volts can be
expected. In the case of lithium batteries, this can sometimes be close to 60 Volts.
•
WARNING! Always check before connecting if all batteries have the same voltage, with a
maximum difference of 0.1 Volt.
•
Check if the ignition on the dashboard is in the “off” position.
•
Ensure that the throttle lever is in the neutral position. If not, the display will provide a notification.
•
Turn the main switch to “on” or “I.
• Turn the ignition key to the right to turn on the system; you should hear a clear click indicating the
relay is engaged.
•
Check if the display is turned on. In the “Advanced” setting of the display, you can also see the
voltage. Does this correspond with what you have measured?
• Gently give a small amount of throttle and check if the engine functions correctly both forward and
backward.
•
Check if, during the acceleration, the display shows a specific number of kW.
• Return the throttle lever to the neutral position.
•
WARNING! Check the motor and controller temperature on the dashboard. Is it approximately
the same as the motor compartment temperature? (The temperature of the motor and
controller is usually not exactly the same.)
•
Turn off the ignition.
•
Turn off the main switch.
• Now connect the shore power cable.
• Check if the charger activates and if it provides the correct signals. Consult the charger’s manual for
guidance.
• After activating the system on the display, check if the battery pack voltage goes to the prescribed
charging voltage. Refer to the battery manual for guidance.
•
Charge the battery pack preferably to its full capacity for the first voyage and for setting up the
display. See the explanation of using the display in chapter 6.
• Take a test run and visually inspect everything, paying close attention to sound and vibrations.
• During the test run, check the number of revolutions (RPM) at full throttle and the maximum engine
power at full throttle (kW) to determine if you have the correct propeller.
• Max RPM: 1400-1500 RPM
• Max Power: 100% to 110%
WARNING! If a high RPM with low power is measured, it means that a propeller that is too
small has been chosen. Conversely, if there is a low RPM together with high power, it indicates
that a propeller that is too large has been selected.
