Life Batteries
Profoto uses the most advanced and reliable rechargeable batteries: Lithium Ion Iron
Phosphate (LiFePO4), short – LiFe batteries. These batteries include sophisticated
electronics: A special constructed BMS board (Battery Monitoring System) controls and
adjusts their output to assure an optimal performance.
LiFe cells offer a very high capacity, are lightweight, stand high loads and are very safe and
reliable. The integrated electronics also protect the LiFe battery against deep-discharge
and overheating. On top they have a much longer life-time than lead acid batteries and can
be used in a wider temperature range. Because of their special construction it is possible to
apply the same chargers for LiFe and Pb (lead acid) batteries; this simplifies the combined
use of new and old battery generators and allows owners of previous Profoto battery
generators to update their packs with the new LiFe batteries.
The AcuteB2 generator is available in two battery versions; LiFe or Lead Acid (Pb). The
AcuteB2 600 AirS LiFe, the AcuteB2 600 344MHz AirS LiFe and the AcuteB2 600 433Mz
AirS LiFe are equipped with a LiFe battery and the AcuteB2 600 AirS Pb with a Pb battery.
The generator cannot be used without a battery in place.
Both battery types can be charged separately or with the battery in place in the generator,
using a standard Profoto Charger. The charger is available in two versions, with different
charging times, see section
Technical data
. The generator can be used during charging.
For a long battery Life, the Pb battery shall be charged as often as possible and preferably
before the battery is fully discharged. The LiFe battery can be charged from any charge
level, but should not be charged for longer time than necessary. Both battery types shall
be fully recharged prior to storage.
The capacity of the Pb battery decreases dramatically when the battery temperature falls
below freezing 0 °C (+32 ºF). Since the LiFe battery is more capable of handling lower
temperatures, we recommend to use the LiFe battery at lower temperatures.
Defective batteries shall be returned to the dealer for recycling. For details about the Pb
and LiFe batteries, see section
Technical data
.
Battery indicator
The Battery Indicator [10] indicates the battery level. The indicator is updated when a flash
is triggered. At start up, all three lamps will light up and a flash should be triggered to get
an updated battery indication. Because of different discharge characteristics, the Battery
Indicator [10] for a generator with Pb battery will slowly go from max to min, whereas the
Battery Indicator [10] for a generator with LiFe battery will remain on max until it suddenly
drops, when there is battery capacity for just a few more flashes.
