USE OF EXISTING BATTERIES
Existing batteries can be used for the thruster, but this option must be considered
with caution. CCA requirements must be met, and you must consider how deeply the
batteries will be discharged before charging can occur if the thruster load is added to
the original load on the battery.
Deep Discharge Bank
If an existing bank of deep discharge batteries can supply the CCA requirements,
this could be an option if they are located close enough to the thruster being
powered. A battery at 40% capacity will supply about .8 volts less than a fully
charged battery, which will reduce performance of your thruster.
Cable and Terminal Requirements
Due to the high current load drawn by the motors, it is essential that the correct
type of cable and connectors are used, and that maximum cable length guidelines
are observed according to the gauge and thruster model. These guidelines are
summarized in the table below. The table assumes cables from the thruster to the
controller have not been shortened.
Cable must be high quality tin coated copper, marine grade cable. Cable ends must
be fitted with high grade cast copper, tin coated compression type terminals and
sealed with double wall heat shrink tubing for moisture protection.
Cables from the motor are 4 AWG. This lighter gauge of cable is used to allow for
easier routing between the motor and controller. It is essential that cable from
battery to controller is much heavier gauge or the motor will not perform properly
and could be damaged.
NOTE:
SAE gauge can have up to 12% less conductor cross-section than
AWG. Use cables of equal or greater AWG as suggested below.

Correct cabling and connection practices are essential to maintaining correct
operating voltage. Batteries must be fully charged before use.
Batteries are often subject to moisture and damp/corrosive conditions, therefore it
is important that the connection terminals are properly sealed to the cables using
heat shrink tubing (supplied).
