Batteries
ATTENTION!
Ensure that there is never any power to the system during
installation and assembly!
The drive operates on 48 Volts. Provide a battery pack that is suitable for this application in terms of
quality and capacity. Use traction, semi-traction - deep cycle, or lithium batteries that meet the
specifications
.
ATTENTION!
When in doubt about the specifications of lithium batteries, it is advisable to consult
WaterWorld. It
It is possible that the batteries may damage the engine, or vice versa if the two are not compatible.
.
1.
Position the batteries in the vessel in such a way that:
a.
the weight is well distributed and the boat lies nicely on the waterline.
b.
the batteries cannot move in the boat after installation.
c.
the batteries are accessible for connection of the cables and for further maintenance work.
d.
the batteries do not interfere with the daily use of the boat.
e.
Cabling to the engine and to the charger is easily possible without unnecessary cable length
2.
Check the individual voltage of all batteries and make sure that they are within 0.1 Volt of each other
before connecting them. If this is not the case, all batteries must be charged individually.
Connect the batteries in accordance with the applicable diagram.
Below are examples of 4 x 12 Volt batteries in series and 8 x 6 Volt batteries in series.

ATTENTION!
Wait with connecting the batteries to the rest of the system until everything is connected properly.
Battery charger
The battery charger must be selected for the
battery pack and be adequate in terms of voltage,
charging capacity in amperes, battery type and use
in a boat.
ATTENTION!
When positioning the charger, think
about the same issues as with the engine and
batteries.
Moisture,
accessibility,
cabling,
ventilation, etc.
