New Flex’ion™ Gen2 li-ion battery for data centers and critical applications: 40% more power, highest safety & low environmental footprint

•2nd generation Li-ion battery system provides up to 220 kW per cabinet, answering the need for high power performance.

•Highly sustainable, Flex’ion Gen 2 operates at high temperatures (35 ºC), enabling significant electricity and water savings.

•Proprietary Li-ion Super-Phosphate technology offers safety at the highest level and is UL 9540A and UL 1973 certified.

Features & Benefits

Flex'ion Gen 2 sets a new standard for uninterruptible power supply (UPS)

Manufactured in Europe, Flex'ion Gen 2 new lithium-ion battery solution provides up to 220 kW per cabinet, boosting power performance by 40 percent compared with the first generation Flex’ion. 

Designed for data centers and other mission critical UPS applications such as hospitals and industrial processes, the Flex’ion Gen2 is compact, lightweight and capable of operating continuously at high temperatures. 

The highest level of safety and reliability:

Flex’ion Gen2 li-ion battery system has passed rigorous testing under the UL 1973 and UL 9540A method. It is certified for use:

• without a built-in fire suppression system, placing Flex’ion at the highest level of safety 

• without an air separation gap between cabinets, minimizing the space required and the Total Cost of Ownership (TCO) of the data center overall. 

Other factors that reduce the TCO are the long calendar life of over 20 years, the low maintenance and the lightweight design. Li-ion batteries are six times lighter than valve-regulated lead-acid batteries (VRLA).

Sustainable, it minimizes carbon emissions and cobalt content

In addition, Flex’ion Li-ion battery technology can operate reliably at high temperatures (35º C), which reduces the HVAC requirements, minimizing energy bills and carbon emissions.

Its low-cobalt content of less than 1% and primary materials sourced from responsible suppliers under the Responsible Materials Initiative (RMI) enables a highly sustainable and environmentally friendly system.
