Now batteries are serially connected with each other: Battery capacity [Wh] and voltage
[V] of battery block rise with the number of serially connected batteries.
Charge [Ah] of batteries does not change with serial connection (for instance: after serial
connection, two serially connected 12 V/100 Ah batteries of 1,200 Wh each will have 24 V,
100 Ah and 2,400 Wh).
Cable set is equipped with a 125 A fuse. In case of a short circuit, fuse cuts circuit and
prevents any further damage.
After battery installation transfer battery bank data, via remote throttle, to on-board com-
puter (chapter 5.3, „Set-up mode“) to be up to date about state of charge and range.
• Serial and parallel configured batteries must always have the same state
of charge. That is why you must use only the same type of batteries in
configurations (same capacity, same age, same manufacturer, same
state of charge) and fully charge each battery separately in your charger
before you connect it up. Differences in the state of charge can lead to
extremely high compensatory currents or overloads on the cables and
plugs or the battery itself. In extreme cases this could even cause fire or
injury.
• Cable cross section for interconnection of batteries must be 25 mm².
Take care that battery poles are clean and corrosion free.
• Firmly tighten srews of battery terminals for fixing to battery poles.
• Disconnect the battery when leaving the boat for a longer time.
4.8 Prevention of damage when connecting other devices to traction batteries
Torqeedo recommends running the Cruise 2.0/2.0 R on its own battery
bank. Other devices such as fish finders, lights, radio, etc. should be
supplied with an additional battery and not be connected to the same
battery bank as the motor.
Connecting other devices to the same battery bank causes uneven
discharge of an individual battery as well as the risk of electrolysis in
case of incorrect wiring.
If it is still desired to use a 12 V or a 24 V device on one or two batteries
of the same battery bank as the motor, the different equipment(s) and
outboard motor must share the same negative terminal of battery bank
(„common ground“). See the following figure:

Note:
The described wiring
scheme above will avoid the
risk of electrolysis, but will
result in uneven discharge
among the battery pack. Tor-
qeedo will not be responsible
for any damages resulting
from uneven discharge of
batteries or incorrect wiring
