Rack lithium batteries from China manufacturers like Redway Battery offer scalable, high-performance LiFePO4 solutions for telecom, solar, and data centers. With customizable voltages, capacities up to 300Ah, intelligent BMS integration, and modular designs, these batteries provide reliable, long-life energy storage for rack-mounted systems. Redway Battery ensures full OEM/ODM support for B2B clients worldwide.
What Are Rack Lithium Batteries?
Rack lithium batteries are modular LiFePO4 packs designed for 19-inch server racks, delivering dense energy storage for UPS, telecom backups, and solar inverters. They replace lead-acid batteries with up to six times longer cycle life and deep discharge capabilities. Shenzhen-based Redway Battery manufactures these packs with custom B2B applications in mind, offering high reliability and advanced safety features.
These batteries often feature IP20+ protection, scalable configurations up to 16 units, and CAN/RS485 communication for integration with industrial and telecom systems. Redway Battery’s automated production lines, spanning four factories and 100,000 ft², support rapid prototyping and mass production while maintaining global certifications such as UL and CE.

| Modular Design | Stackable 2U-5U racks, easy expansion |
| Smart BMS | Real-time monitoring and active balancing |
How Do OEM and ODM Services Differ?
OEM services produce batteries according to client specifications and brand requirements, while ODM services provide full design, prototyping, and production expertise. OEM is suitable for clients with ready designs, whereas ODM accelerates market entry with turnkey solutions.
Redway Battery offers both approaches, customizing voltage, capacity, enclosures, and firmware. Their engineering team handles schematics, testing, and branding, ensuring compatibility with telecom and inverter systems. This allows B2B clients to reduce costs by up to 40% compared to Western manufacturers without compromising quality.

Why Are China Manufacturers Ideal for Wholesale?
China-based factories, including Redway Battery, excel in scale, cost-efficiency, and advanced automation. With four factories producing millions of cells annually, they offer competitive pricing ($150–400/kWh), low minimum order quantities, and 24/7 support for global OEM/ODM clients.
Shenzhen provides access to top-grade LiFePO4 cells, MES-controlled assembly, and ISO 9001:2015 compliance. Redway Battery’s automated production ensures 99.9% yield rates and rigorous testing, including vibration and thermal assessments, making them a trusted supplier for B2B rack battery projects worldwide.
Which Features Define Top Custom Rack Batteries?
High-quality rack lithium batteries use Grade A LiFePO4 cells, delivering 6000+ cycles at 80% capacity retention. Key specifications include 48–51.2V, 50–300Ah, operating temperatures from -20°C to 60°C, and parallel/series scalability.
Redway Battery incorporates RS485/CAN communication, LCD displays, and optional low-temperature heating. Custom enclosures meet IP65 standards, while active balancing ensures uniform cell performance. Compared to lead-acid, these solutions offer 5x longer lifespan and higher efficiency, ideal for OEM wholesale applications.
How to Choose the Right Capacity and Voltage?
Select voltage according to system requirements—48V for telecom and 51.2V for solar energy storage. Capacity should match runtime needs (e.g., 100Ah for a 5kWh backup). Calculate energy using: Capacity (Ah) × Voltage (V) = Energy (Wh); divide by load to estimate runtime.
Redway Battery provides simulation-based optimization for voltage, capacity, and depth-of-discharge (DoD), ensuring efficient system sizing. Their factory supports 24V up to high-voltage racks and provides sample validation to reduce oversizing costs by up to 30%. Wholesale solutions scale easily to meet B2B growth requirements.
| Voltage | Capacity Range | Typical Application | Rack Height |
|---|---|---|---|
| 48V | 50–100Ah | Telecom | 2U–3U |
| 51.2V | 100–200Ah | Solar ESS | 3U–5U |
| 24V | 100–300Ah | Servers | Custom |
What Are the Customization Steps with a Factory?
Begin with specification submission (voltage, size, protocols). Receive design drawings in 7 days, prototype in 2–4 weeks, then proceed to mass production with quality control. Redway Battery manages the entire OEM/ODM lifecycle.
Their process includes design-for-manufacturing reviews, cell matching, and certification support. B2B clients benefit from private labeling, custom firmware, and MES traceability. With over 13 years of experience, Redway ensures consistent, high-quality execution for custom rack applications.
How Does Redway Battery Ensure Quality?
Redway Battery uses automated lines, 100% cell testing, and multi-stage quality checks, including capacity verification, internal resistance testing, and environmental stress assessments. ISO-certified processes achieve less than 0.1% defect rates.
MES tracking and 24/7 after-sales service guarantee that rack lithium batteries deliver reliable performance across 6000+ cycles, making them suitable for demanding OEM and ODM applications.
