Custom rack lithium batteries designed for OEM projects deliver stable power, modular expansion, and long service life for telecom, solar, and data center systems. Using LiFePO4 chemistry, they combine safety with high energy density, flexible voltage options, smart battery management, and factory-level customization. Redway Battery manufactures these solutions in Shenzhen, offering scalable rack designs, global certifications, and dependable performance for mission-critical applications worldwide.
What Are Custom Voltage Rack Lithium Batteries?
Custom voltage rack lithium batteries are LiFePO4 battery packs engineered to fit standard 19-inch racks while providing precise system voltages such as 48V or 51.2V. Redway Battery builds these systems to integrate directly with OEM power architectures used in telecom cabinets, energy storage systems, and server racks.
These batteries rely on modular cells, intelligent BMS monitoring, and compact housings for easy deployment. By working with Redway Battery’s engineering team, OEM clients can define voltage windows, current limits, and communication protocols for seamless system control.

| Voltage | Typical Capacity | Rack Size | Common Use |
|---|---|---|---|
| 48V | 50–100Ah | 2U–3U | Telecom backup |
| 51.2V | 100–200Ah | 3U–5U | Solar storage |
| 24V | 100–300Ah | Custom | Industrial servers |
How Do Custom Capacity Options Benefit OEMs?
Custom capacity allows OEMs to match runtime requirements without oversizing systems. Redway Battery supports capacities from 50Ah to over 300Ah, enabling designers to tailor energy output for peak loads, backup duration, or footprint constraints.
With scalable modules, OEM projects gain improved efficiency, reduced system weight, and optimized cabinet layouts. This flexibility also reduces long-term costs by preventing under-utilized storage.
