The size of the battery bank required to power the outboard motor will depend on the
current draw you plan to regularly place upon it and the distance you plan to travel. It
is difficult to determine the current draw until the outboard motor is used as each boat
has a different hull shape, length, displacement, speed, and daily operating cycle
requirement. Only one 48V Barrus battery module is required to run the boat at 6-
10hp, a minimum of two are required for 20hp. Additional battery modules can be
added to increase the range. Battery modules can be easily connected in parallel to
form a larger capacity battery bank.
If using batteries from other manufacturers or sources, these may be either
12v or 24v. The batteries must be connected in such a way as to give 48v.
Always use Blue Anderson type connector plugs for 48 Volt batteries and
connecting cables to avoid potential injury and/or damage to the battery and outboard.
Note : Different coloured Anderson type connectors are used for different voltages to avoid
connecting batteries of the incorrect voltages.
