Lithium-ion battery maker Green Cubes has launched a range of rack-mounted 48V DC batteries for data centers.

The Guardian batteries are aimed at rack mount installations in the telecom and data center industries, and follow up on the US-based company announcement in March that it would be making data center batteries, as well as entering Europe with a new factory in Slovakia.

The new units are designed to work 24x7 to support mission-critical functions, replacing lead-acid batteries for uninterruptible power supplies (UPSs).  

“Telecom service providers and data center operators supporting mission-critical IT infrastructure demand batteries that perform reliably when grid power fails,” said Jeffrey VanZwol, chief marketing officer of Green Cubes. “The Guardian Lithium-ion batteries provide exceptional cycle and calendar life, simplify installation, eliminate the need for maintenance, and lower the total cost ownership of a typical battery backup installation.”

The batteries range from two to four rack units (2RU to 4RU) and fit both 19 in and 23 in cabinets, delivering a total charge of 105 Ahr to 175 Ahr. The batteries have a nominal 48V output and charge and discharge up to 100 Amps. They include a battery management system (BMS), charging electronics, and proprietary energy balancing technology (EBT) that enables active current control, load sharing, and state of charge balancing across connected units.

They also have active thermal management and can have both lithium nickel manganese cobalt (NMC) and lithium iron phosphate (LFP) chemistries. 

Founded in 1986, Green Cube has previously been best known for its forklift truck batteries. These products will be shown this week at Battcon 2021 in Hollywood, Florida.
