Danger of injury from short circuit.
This can result in severe physical injuries or death.
Remove metal jewellery and wristwatches before you start work on batteries
or in their vicinity.
Always put down tools and metal objects without making contact with the
battery.
When connecting the battery, ensure correct polarity and secure
connections.
Battery terminals must be clean and free of corrosion.
Do not store batteries hazardously in a box or drawer, e.g. an insufficiently
ventilated locker.
CA UTI O N !
Damage to the battery or other electrical loads from a short circuit.
Material damage can result.
When working on the batteries, always switch the system off at the main
switch.
When connecting the batteries, ensure that you first connect the red positive
cable followed by the black negative cable.
When disconnecting the batteries, ensure that you first disconnect the black
negative cable followed by the red positive cable.
Never transpose the polarities.

Do not lead the cables over sharp edges, and cover all open terminal caps.

Comments on choice of batteries

In principle, Torqeedo recommends the use of lithium batteries.
When using lead batteries, comply with the following:
Under no circumstances use starter batteries, because when deeply discharged
these become permanently damaged after only a few cycles.
If lead batteries are to be used, then so-called traction batteries are
recommended. These batteries are designed for an average discharge level of 80
% per cycle.
So-called marine batteries can also be used. For these battery types, the charge
level should not fall below 50%. Batteries of at least 400 Ah hours capacity are
therefore recommended.
The available battery capacity is significant for the calculation of running times and
ranges. This is stated in Watt hours [Wh] below. The Watt hour value can easily be
compared with the motor's stated input powers in Watts [W]:
The Cruise 10.0 has an input power of 10,000 W.
During one hour at full throttle, it consumes 10,000 Wh.
If you use the system with just one Power 48-5000 battery, then the system is
regulated to a maximum input power of 6,300 W.
The rated capacity of a battery [Wh] is calculated by multiplying the charge [Ah] by
the rated voltage [V]. A 12 V, 100 Ah battery therefore has a rated capacity of 1,200
Wh.
For lead/acid, lead gel, and AGM batteries, the rated capacity calculated in this
way is not available in full. This is because of the limited high current capability
of lead batteries. In order to counteract this effect, the use of larger batteries is
recommended. For lithium-based batteries, this effect is negligible for practical
purposes.
For the expected ranges and running times, in addition to the boat type's actually
available battery capacity, the selected power step (low running time and range at
higher speed) and for lead batteries, the external temperature play a significant role.
We recommend using larger batteries, rather than connecting several batteries in
parallel.
