Typical applications for LiFePO4 rack-mounted batteries include data centres, telecommunications, renewable energy systems and backup power.
Data centres
High energy density, long cycle life and low maintenance for continuous UPS and IT loads.
Telecommunications
48V DC plants with RS485/CAN and optional SNMP for remote sites.
Backup power
Cabinet-ready modules that replace VRLA strings in UPS rooms.
Renewable energy
Hybrid solar storage in standard 19-inch racks.
EV charging stations
Buffer storage next to chargers that share a rack room.
Industrial settings
Factory and plant backup where a server rack is already the standard enclosure.

What buyers usually ask
What are LiFePO4 rack mounted batteries?
Lithium iron phosphate batteries designed for installation in standard server racks or cabinets. They provide efficient energy storage where space, ventilation and standardised dimensions matter.
Which inverters are compatible?
The PM series works with inverters from Victron, SMA, Goodwe, SRNE, Solis, SAJ, Growatt, Luxpower, Voltronic, Deye and others. Confirm protocol (RS485/CAN) with engineering before the first sample.
Three things that make a useful OEM enquiry
Redway accepts OEM, ODM and SKD orders, including logo or brand-name printing on the pack.
Specification
Please let us know the operating voltage requirements; and if any additional functions are needed, such as 10 second discharge and 10 second charge.
Quantity
A minimum order quantity (MOQ) is not required. However, a realistic annual volume will help you get a better price.
Application
Our engineers can provide you with more suggestions under your budget if you let us know your application or details about your project.
Certified for transport, safety and quality
Redway lithium batteries are UN 38.3 certified and built from Grade-A cells. Selected models also hold UL 1973, UL 2580 and IEC 62133. ISO 9001:2015 and ISO 14001:2015 cover the quality and environmental systems used for industrial models. OEM clients can request extra laboratory services with the quotation.

Energy Storage & Rack Batteries — guides
Choosing the system, integrating it, and keeping it running.
Voltage and capacity follow the inverter
A 48V/51.2V rack module is the default for hybrid inverters; the amp-hours then follow the backup window you need, not the shelf label.
