IGNITION DETECT
The MiniBoostPRO is equipped with an ignition detect cable, which is
designed to prevent your primary battery from excessive discharge and
detects when the vehicle alternator is turned on. If the ignition detects the
alternator is running, the MiniBoostPRO will start charging the secondary
battery when the primary battery voltage is above 12V. If the ignition is
detected as off or the ignition wire is not utilised in the installation, the
MiniBoostPRO will start charging when the primary battery voltage is above
12.6V (refer to Table 2).
FUSING
Fuse protection of the MiniBoostPRO is required at the primary positive
terminals, battery positive terminals, battery chemistry selection cable and
the ignition detect cable.
The MiniBoostPRO’s recommended fuse for the primary positive and battery
positive terminals is an automotive fuse (rating 40A) and for the battery
chemistry and ignition detect cables, is an Automotive fuse (rating 2A).
Users must place the fuse as close as possible to the battery.
Fuse protection is required even if no BMPRO battery management system is
installed.
WARNING
Do not connect the ignition cable to the battery positive terminal indefinitely
when the MiniBoostPRO is not charging.
