Built with Saft’s proven Super Lithium
Iron Phosphate (SLFP TM) proprietary
technology, Flex’ion offers superior
performance whilst maintaining the
highest levels of safety, reliability and
availability.
Flex’ion battery systems are designed
for AC and DC UPS (Uninterruptible
Power Supply), ancillary power backup
and switchgear applications in
mission critical facilities, such as data
centers, telecom, offshore / onshore oil
& gas and utility markets.
Flex’ion battery systems are designed
and manufactured at Saft’s state of the
art Li-ion sites in North America
(Jacksonville, Florida) and Europe
(Nersac, France and Raškovice, Czech
Republic).
TM
Flex’ion modular design provides
outstanding system flexibility in terms
of power, operating voltage and
backup time answering your specific
application’s needs.
TM
TM
Flex'ion advanced Li-ion battery
solutions are fully IEC, UL and UN
certified to address the most
demanding market requirements.
TM
This cutting-edge battery system delivers a reduced total cost of ownership (TCO),
an industry-leading power and energy density, and an outstanding97% roundtrip*
efficiency that reduces power consumption.
*Roundtrip : charge / discharge
TM
Saft lithium-ion technology benefits
from more than 25 years of worldwide
industrial and field experience in
standby, space, defense, aviation and
energy storage.
It is available either as a full system
including cabinets or as a kit of
sub-componentsto be integrated
with power electronic equipment.

Flex’ion fully integrated SLFP battery solution comprises modules, BMM
(Battery Management Module), MBMM (Master Battery Management Module) for
multi-string paralleling, Intelli-Connect supervision system and cabinet.
TM
Its modular design allows serial and serial/parallel connection to reach
different energy and power requirements, answering your specific application’s
needs.
Serial connection from 87 V to 750 Vdc (CE) and 600 Vdc (UL)
BMM (Battery Management Module) included for string management
and interfacing
Multi-string paralleling up to 18 strings through MBMM (Master
Battery Management Module) to achieve :
- High power up to 2.3 MW
- High energy up to 500 kWh
Intelli-Connect integration system
- Facilitates power management and allows use with
conventional constant potential (CP) or smart chargers
- Enables the battery string to discharge, even if the charge
circuit has opened
Energy to High power modules
Flex’ion SLFP compact solution is
based on 3 different modules:
23 M Fe, 46 M Fe (Energy /
Medium power)
46 P Fe (High power)
TM
The patented Super Lithium Iron
Phosphate (SLFP ) chemistry
invented by Saft R&D has a flat
discharge curve, which is a natural
fit for UPS systems that supply
constant power.
TM
Its 3.7C (23 volt & 46 volt M Fe) and
11C (46 volt P Fe) maximum
discharge power capability is
optimized for high power applications.

Technical data
An advanced Battery Management System
The battery management system includes a Master Battery Management
Module (MBMM), Battery Management Modules (BMM) and an Intelli-Connect
proprietary monitoring system providing the following functions:
Monitoring and control of voltage, current and temperature at cell level
State of Charge (SOC) balancing between cells, modules and strings
Real time calculation of:
- Charge and discharge current limits
- SOC using temperature, aging, voltage and current
Programmable logic controller (PLC) with pre-loaded protocols:
CANopen, Modbus (RS485 or TCP/IP), Ethernet (IEEE 802.3) and OPC
communication
Indication of:
- State of Health (SOH) of the system integrating calendar aging and cycling
- State of Charge (SOC) of the system

Alarm and fault management
A scalable 19” rack cabinet (optional)
The battery modules fit standard 19” racks and are mounted in Saft designed cabinets,
ensuring reduced floor space in battery rooms. They are available in both certified
seismic and non-seismic versions.
Saft’s Flex’ion cutting-edge design includes an intuitive optional
Human-Machine-Interface (HMI) and front panel battery condition visual
indication.
