Mounting: 4 mounting options available. For the use
with Hobie kayaks, the Hobie specific motor “eVolve” is recommended
(available through Hobie dealerships). For the use with Grabner kayaks,
please use Grabner mounting kits. For the use with Prijon kayaks, please
use the Prijon rudder mount. By using the mounting ball included in the
delivery, the Ultralight can be mounted onto almost any kayak.
Steering: can be attached to kayak’s own steering system/rudder.
Watertightness: All motor components are watertight, protected against complete immersion.
Safety: The motor shuts off when the magnetic key on the
remote throttle control is removed. Therefore, for safety reasons, the
magnetic key should be attached to the wrist or the life vest. If the
kayak capsizes, the motor shuts off automatically to avoid possible
injury.
Battery charge time: When fully discharged, the charge time with the charger supplied is approx. 12 hours.
Lithium battery life expectancy: Charge cycles are
not the main factor affecting the service life of the lithium-manganese
battery. The battery does not have a memory-effect. Generally, a loss of
capacity of 4% per year can be assumed. Aging is accelerated if the
battery is exposed to high temperatures for long periods and if it is
stored fully charged for long periods. Therefore, the battery can be
used in very hot conditions, but should be removed from the sun and
stored in a
cool place when not used. If it is stored for a longer period
of time, its charge status should be about 50%. If these instructions
are followed, your battery will have a life expectancy of some 6-10
years.
Integrated battery specifications: The integrated battery has a capacity of 320 Wh, i.e. 11 Ah at 29.6 V.

* Torqeedo static thrust measurement is based on globally valid ISO standards. Static thrust figures for conventional trolling motors are measured digressively, which results in higher values. In order to compare Torqeedo static thrust data with conventional trolling motors, add approximately 50% to the Torqeedo static thrust values.
