Main features:
●RUGGED AND RELIABLE: Battery packs are built in rugged aluminum chassis, machined out of a
single brick of aluminum for reliable operation on the field. Only high-quality Li-Ion batteries are
used.
●LARGE CAPACITY: Battery packs ensure enough power for your on-road and field test and
measurement applications so you don't have to worry about losing any data due to lack of power
supply. DS-BP2i total capacity is 192Wh and DS-BP4i total capacity is rated to 384Wh, this will
ensure 3 hours of operation for SBOX data logger with 32 channel SIRIUS DAQ system without
replacing batteries.
●HOT-SWAP FUNCTIONALITY: Internal Li-Ion batteries are hot-swappable, meaning they can be
replaced during the measurement to ensure your data acquisition system never runs out of
power.
●DAISY CHAIN: Battery packs can be daisy chained together to further increase the autonomy.
●ISOLATED POWER SUPPLY: For in-vehicle measurements, an isolated power supply on battery
packs will guard you against unwanted ground loops.
●REVERSE POLARITY PROTECTION: Battery packs are protected against wrong connections to
the input power supply.
●ADAPTIVE CHARGING: Charging current is dynamically adapted, depending on the output load.
When there is no significant load at the output, the batteries are charged with 2 A per battery.
When external load increases and the power of external PSU rises close to the limit, charging
current is reduced to 1 A per battery. If the load is still increasing, the charging of batteries is
stopped. With this feature, we ensure that maximum required power from external supply is
limited.
●STATUS INDICATOR: Battery pack comes with LCD status indicator as well as USB connection to
the DAQ unit so you will always know how much power you have left.
●USB: Battery packs are equipped with a USB connector. It is used to connect the battery pack to
the computer, where it introduces itself as native battery for windows (HID UPS Battery). Icon in
the task bar also appears with the status of batteries. Battery pack information can also be
observed in DEWESoft.

Important
Expected discharge of battery packs is 3% - 5% per day if in standstill mode only with
the latest firmware performed by the Service department or by contacting
[email protected] for more information.
Battery packs currently have RRC, RRC2024 batteries. Older versions might have had
batteries by Inspired Energy, NL2024HD22. Please make sure not to swap batteries
between older and newer systems as the mechanics and the connectors are not
compatible to avoid any damage.

Batteries
Li-Ion rechargeable Smart Battery packs are used. The battery is composed of twelve (12) Lithium Ion
rechargeable 18650 cells, assembled in a 4 series / 3 parallel (4S/3P) design. Each cell has an average
voltage of 3.60V and a nominal capacity of 2200mAh, providing a battery pack of 14.40V and 6600mAh
nominal. The battery is designed to communicate with a host or a charger through the System
Management Bus (SMBus) protocol. The battery is SMBus and SBDS Revision 1.1 compliant. The battery
design includes protection for over charge, over discharge and short circuit. Additional safety measures
are designed into the battery to protect against over temperature and over current situations.
Hot swapping
Battery pack is designed so that batteries can be hot-swapped while still providing output power. When
hot swapping batteries, output voltage and state of charge must be taken into account. When there is
one full battery in the system and another one is empty, the full one takes all the load. To prevent battery
damage, maximum output current from a single battery is limited.
Important
●Recommended Hot swapping at > 15-20% total SOC.
●Replace one-by-one all batteries with matched SOC.
●Single battery will not support full load or long duration between swapping.
Caution
Output current from a single battery is limited to 7.0 A - 7.5 A.
Maximum power out when Hot swapping:
●DS-BP2i: 75 W
●DS-BP4i: 220 W

TECHNICAL REFERENCE MANUAL
Isolation
Input and output electrical ground are galvanically isolated. This allows us to use BP on the different
ground potentials and thus protecting from unwanted ground loops.
Warning
Isolation shall be considered as BASIC INSULATION. Basic insulation forms a single level of
insulation that provides basic protection against shock.
Caution
Isolation voltage specification (500 V) should be considered as MINIMUM ISOLATION PEAK TEST
VOLTAGE. Maximum isolation peak test voltage level could be two to four times higher.
Stacking
Hint
Both battery packs - DS-BP2i and DS-BP4i are built in standard SIRIUS form factor, so you can
stack your power supply under your DAQ device. Clever click mechanism will enable the battery
to attach to SIRIUS and/or SBOX instruments. This ensures safe placing into the measurement
environment, to prevent rolling and bouncing around.
