• When using the motor with lead-based batteries (gel or AGM)
please note that the values displayed for the range are based on
the average performance curves of various batteries. Lead-based
batteries are available in qualities that vary strongly. Therefore the
indicated outstanding range can not be exact for lead-based
batteries.
• False information on the charge level (eg. due to pressing the “cal”
button twice when the batteries are not full) results in the on-board
computer over-estimating the battery‘s charge level and your range.
• At the beginning of each season the on-board computer has to be
calibrated in order to take into account the aging of the battery bank.
• Other devices that are connected to the motor’s battery supply can
not be considered when calculating the remaining charge level and
range. In this case your batteries’ charge level and outstanding
range are lower than indicated on the display
• Charging the battery bank during the journey (e.g. using solar
systems, wind turbines or generators) cannot be taken into account
by the on-board computer. In this case your batteries´ charge level
and outstanding range are higher than indicated on the display.
If you conduct the calibration on the open water (and not tied up in port) please note that
the motor stops automatically when the aforementioned conditions are fulfilled, thus
signaling the completion of the calibration. The motor can be switched on afterwards to
head towards port. Note that the remaining range is low.
The calibration helps the on-board computer to learn how much capacity the battery
bank that is supplying the motor has lost through aging. These values are included in the
calculation of future charge level indications in percent and ranges. The on-board com-
puter overwrites the values stored in the set up menu for ampere-hours for your battery
bank. If you want to assess the status of the battery bank and check the capacity loss, go
into the setup menu, look up the value for ampere-hours and compare it with the original
values. Please do not change the value set during the calibration journey as otherwise
the on-board computer will make false assumptions.
