Handling
Battery status and charging
The battery status is indicated by the battery level indicator [26] on the display. The battery
status can also be checked by pressing the CHECK button [19] on the battery pack. See
also section
Technical data .
For optimal performance, the battery should be fully charged prior to usage. The battery
can be charged while in use and from any charge level. Only use the Profoto Battery
Charger 2.8A or the Profoto Car Charger 1.8A. Do not use the Profoto Battery Charger 4.5A,
as it may decrease the battery lifetime.
If the battery has not been used for a long time, the Profoto Battery Charger 2.8A should be
used. The Profoto Car Charger 1.8A should not be used in this case.
1. Connect the battery charger to the battery charging connector [18] on the battery pack.
2. Check that the battery charger indicates that charging is in progress.
3. When the battery charger indicates that the charging is completed, it is recommended
to disconnect the battery charger from mains power and from the battery pack.
For increased battery lifetime, do not leave the battery uncharged for a long time.
Battery mounting
1. To mount the battery, fit the battery pack in place and push firmly until the battery
pack locks in place. Make sure there is a “click” sound, indicating that the battery
pack is properly secured.
2. To dismount the battery, first switch off the B2 unit. Press the battery release button
[20] and pull out the battery pack.
Stand mounting
The B2 lamp heads can be mounted on a traditional light stand, using the supplied stand
attachment. As an alternative, the stand attachment can be removed and the lamp
head can be mounted on a special grip or stand, a camera flash bracket or other special
equipment for more convenient use.
Mounting on a traditional light stand:
1. Fit the stand adapter [38] to a light stand and secure it with the clamp screw [37].
2. The lamp head can be directed upwards/downwards when the tilt-lock handle [36]
is loosened. Fasten the tilt-lock handle [36] when the lamp head is correctly directed.
Mounting on a special stand/grip or camera flash bracket:
1. Unscrew the stand attachment screw [35] and remove the stand attachment.
2. Thread the lamp head onto the special equipment.
Note that the thread size of the B2 lamp head is 3/8” and that a thread adapter may be
needed for other grips and brackets.
