Two-Battery System (Cabin, Magnum Pro) - buster MAGNUM PRO Betriebsanleitung

When leaving the boat unattended for a long period, switch off the current using
the main switch. Also switch off the current before performing electrical installation
work. The automatic bilge pump, the radio and the optional heater remain
operational and can be deactivated only by disconnecting the battery terminals.
When connecting or disconnecting batteries make sure no metal tools make contact
with the aluminium parts of the boat or both terminals of the battery simultaneously.
Recharge the batteries only with the boat's engine or a battery charger appropriate
for the battery type. Recharging a battery with excessive current may cause the
battery to explode. Make sure the battery does not boil over when recharging and
spill battery acid into the boat.

Two-battery system (Cabin, Magnum Pro)

The Buster Cabin is equipped with a one- or two-battery electrical system. The
battery, main switch and fuse panel are located in the battery enclosure on the left
side of the boat.
The two-battery system uses two batteries. The primary battery is principally used
as the starter battery, while the second battery is used to supply power when the
engine is turned off and no recharging current is available. Both batteries have a
separate main switch that is used to connect the batteries to the boat's electrical
system or disconnect them from it. The battery is switched off when the switch is
in the OFF position. When the boat's engine is started and the boat is running, it
is recommended that both switches be kept in the ON position. The charging relay
ensures that both batteries are recharged while the engine is running. When you
want to use the electrical system of the boat with the engine not running, the starter
battery should be disconnected from the system by turning the main switch of the
battery to the OFF position. The wiring diagram of the double battery is presented in
Appendix 3.
When purchasing or replacing batteries, it is recommended that the primary battery
be a starter battery able to produce high current. The second battery should be
a deep cycle battery with high energy density, such as an AGM, gel or lithium-ion
battery.
Never switch off the current using the main switch when the
engine is running.
Do not alter the boat's electrical system or associated diagrams.
Only a skilled boat electrician is allowed to modify and service
the system.
