1. Introduction
Torqeedo Power 26 – 77 is a high performance battery for extreme applications.
In general they are used where ever low weight; high electric capacity and high cur-
rent are needed.
The last generation of lithium-manganese cells (LIMA) is used in the Torqeedo batteries. Batteries with these cells offer the following advantages:
• Increased energy density over lead batteries: the high-power batteries of
the Torqeedo Power range are lithium based and have an enormous energy
density. This is a decisive advantage when you consider the limited volume
and weight in the boat. There are also significant advantages over heavy lead
batteries when it comes to handling.
• Improved resistance to high current: conventional batteries can only provide
a fraction of their nominal capacity in the case of load in the typical power
range of larger electric motors. Torqeedo Power batteries, on the other hand,
never let you down even when faced with the utmost loads on a boat.
• Higher charge stability: Torqeedo Power batteries remain charged for several
months even when they are stored. This is particularly important for the use of
the electric drive as an auxiliary motor. Making it way superior to conventional
batteries.
• Improved performance in the cold: lead batteries hardly perform at all at cold
external temperatures. The Torqeedo power, on the other hand, releases practically its full power even at cold outside temperatures. This is a tremendous
advantage should an electric motor be used in cold weather situations.
• Higher safety standard than all other lithium-ion based battery systems:
the LIMA lithium-manganese cells used by Torqeedo are currently the only lithium-ion batteries which also withstand all safety standards when the safety
electronics are switched off. Nevertheless, each and every cell of the Torqeedo
Power battery has its own safety mechanism. Torqeedo is the first provider to
make the LIMA cells available for boat drives.

3. Safety instructions
• Please read this manual carefully and respect the safety instructions.
• The connecting of several batteries must only be carried out by
qualified personnel.
• When connecting the motor or other electrical device only use suitable wire cross sections (see chapter „Installation“).
• Please complete your electrical installation with a battery main
switch, which is approved for at least 125A and a fuse of 125A or
use a cable set that is equipped with both.
• Please make sure that the junctions of the contacts are well done.
• Protect Torqeedo Power against wet conditions.
• Check the housing regularly for mechanical damages.
• Only use charger, which are approved for lithium-ion batteries and
respect the maximum final charge voltage and the maximum
charge current.
• Do not open or drill any holes in the housing.
• Protect the Torqeedo Power battery against sliding and inclining.
• Protect Torqeedo Power battery against direct sun exposure.
• The battery should have a remaining capacity of 80% to 100% if
you want to store it for a longer period of time.

5.2 Battery state of charge display
LED Description
20 blinking Remaining charge below 19%
20 constant Remaining charge between 20% – 39%
40 constant Remaining charge between 40% - 59%
60 constant Remaining charge between 60% - 79%
80 constant Remaining charge between 80% - 97%
100 constant The battery is fully charged (over 97%)
The LED’s on und off do not have any function.
5.3 Ventilation
In order to avoid any over pressure Torqeedo Power is equipped with a ventilation on
the backside of the hermetically closed housing and a hydrophobic membrane.
• Do not damage the ventilation.
• Do not cover the ventilation.
• In case of damage please contact the Torqeedo Service.
6. Installation
Only qualified personnel are allowed to install Torqeedo-Power batteries.
Please take care that the wire cross section corresponds to the mentioned values in
the table.
We do not recommend
using wire cross sections smaller than
25mm².

7. Charging
To charge the Torqeedo Power Battery please make sure to use only charging units
which were approved by Torqeedo. In case you use a “none approved” charging unit
the 2 year warranty will be voided.
Charging times of approved charging units:
Charge
power
Charging times to 100%
450 W approx. 4.8 h
900 W approx. 2.6 h
Please respect the following security instruction independently from the used
charger.
• Each cell must be charged separately in case of serial connected
batteries.
• Please make sure of sufficient ventilation in order to evacuate the
generated heat.
• Please make sure that the opening of the ventilation of the battery is
not covered.
• Please make sure that the connected motor or electrical device is
switched off during the loading process.
Please respect the following instructions for the Torqeedo charging unit:
1. Please connect the battery with the charger first.
2. Please plug the charger.
3. The charging process is starting automatically.
4. The charging process terminates automatically as soon as the battry is fully
loaded (100%).
For any other charger please respect the operating instructions of the used charger.
8. Storage and care instructions
You can use all commercially available detergents, which are suitable for plastics for
cleaning Torqeedo Power. Please use contact oil to service cathode and anode.
The optimal storage temperature is between 5° and 15°C. Please notice that the battery should have a remaining capacity between 80% and 100% if you want to store it
for a longer period.
