4. Then, choose whether the battery status shall be displayed in percent or in volts.
5. The next step is to supply the on-board computer with information about the batteries.
Start with entering whether the motor is connected with lithium batteries or with lead-
gel or AGM batteries. Select “Li” for lithium or “Pb” for lead-gel or AGM batteries.
Confirm your selection by pressing “setup” again.
6. Enter the size of the battery bank. For this enter the ampere-hours (Ah) for the batte-
ry bank. Please use the throttle lever to select the correct number of ampere-hours.
Pushing the ”setup“ button will confirm your selection and exit the setup menu.
Remember: a battery bank consisting of two 12 V/200 Ah batteries connected in series
has a total capacity of 200 Ah at 24 V (not 400 Ah).
The battery charge status and remaining range can only be calculated after completing
the initial setup and the first calibration (see chapter 5.3.3.2).

5.3.2.2 Usage and calibration of battery charge display
Having entered the battery information in the setup-menu, the on-board computer now
knows the capacity of the battery bank. When the motor is in use, the on-board com-
puter measures the consumed power and determines the percentage of battery charge
remaining and the remaining range based on the current speed.
The calculation of the remaining range takes into account the fact that lead-based
batteries do not provide their full capacity at higher electrical currents. Depending on
the battery used this effect may result in the battery charge indicator showing a relatively
high charge level in percent but the remaining range at full throttle is very low. By mo-
ving slower you can still use the available battery charge.
