Choose the Right Server Rack Battery Format for Your Project
What product types do we have?
RAKOUR's rack-mount systems are engineered for density, scalability, and seamless integration.
RAKOUR’s product line is organized around three distinct physical formats, each sharing a common 51.2V LiFePO4 architecture. Whether a project requires a compact rack slot, a floor-standing cabinet, or a scalable high-voltage string, the correct format is already in the lineup — no custom engineering required to begin.
HV Rackable Series — Stack 8 to 17 Modules in Series
The HV Rackable line uses 51.2V modules (200Ah, 280Ah, or 314Ah per module) connected in series through a Battery Control Unit (BCU). A single set can operate at system voltages ranging from 358.4V to 980V depending on module count, making it directly compatible with high-voltage inverters such as the DEYE 50kW and 80kW series. Up to 4 sets can run in parallel, supporting large C&I deployments.
LV Series — Rackable 51.2V 100Ah–314Ah & NSTLV 10.2K–16K
The LV Rackable series spans four capacity tiers — 100Ah (5.12kWh) to 314Ah (16.08kWh) — mounting horizontally into standard 19-inch racks at IP20, with up to 15 modules in parallel delivering 241kWh per cluster. The NSTLV Wall-Mounted & Ground Wheel series covers 10.24kWh to 16.08kWh in an IP54 floor-standing enclosure, suited for semi-outdoor installation. Both series support CAN, RS485, and RS232 communication, parallel expansion up to 15 units, and feature an integrated touch color screen for local status monitoring.
Commercial Battery Storage Applications — From Rooftop Solar to Peak Shaving
What applications are the product suitable for?
RAKOUR systems are validated across C&I, telecom, off-grid, and grid-edge deployment scenarios.
The product architecture is intentionally application-neutral. The same LFP module that powers a residential solar storage system can, when connected in series strings via a BCU, form the energy block for a 200kWh+ commercial battery storage installation. Application fit is determined by inverter selection and string configuration, not by sourcing a different product.

48V LiFePO4 Battery Chemistry — Why Every RAKOUR Pack Uses LFP
What about safety, reliability?
All cells are prismatic LiFePO4 in 16S1P configuration, operating between 46.4V and 57.9V.
RAKOUR does not offer NMC or lead-acid alternatives. Every product in the lineup uses lithium iron phosphate (LiFePO4) chemistry, selected for its thermal stability, cycle durability, and resistance to thermal runaway — not as a marketing choice, but because LFP is the only chemistry that satisfies IEC 62619 safety requirements at this form factor without active suppression systems.
Why Lithium Iron Phosphate Battery Pack
LiFePO4 cells offer a flat discharge curve, thermal stability up to 270°C before decomposition, and a 3,000–6,000 cycle lifespan at 80% DOD. Unlike NMC, LiFePO4 eliminates oxygen release risk during thermal events, making it the correct choice for enclosed commercial installations.
51.2V Architecture and Cell Configuration
RAKOUR's 51.2V nominal systems use a 16S1P cell configuration. Operating voltage range: 44.8V–58.4V. This architecture aligns directly with 48V bus systems while providing headroom for efficient charging at standard 56V–58.4V charge voltages common in hybrid inverter platforms.
Battery Management System (BMS) Design
Each RAKOUR unit includes a master BMS managing cell-level voltage monitoring (±5mV accuracy), temperature sensing at 4–8 points per module, and state-of-charge estimation via coulomb counting with OCV correction. Protection logic covers over-charge, over-discharge, short circuit, and over-temperature events with <1ms response time.
Wholesale Battery Orders Backed by Third-Party Certification
What about certification?
CE, IEC62619, UN38.3, ROHS, and MSDS documentation is available for every product in the lineup.
RAKOUR products are certified through independent third-party testing laboratories, not self-declared. This distinction matters for B2B buyers who need to import, install, or resell batteries under local electrical codes, building regulations, or insurance requirements. Certification documents are available per SKU prior to purchase — no NDA required for standard compliance review.

Battery Management System (BMS) — Architecture and Protection Logic
How to protect the system?
Every RAKOUR unit ships with an embedded BMS; HV systems add a master BCU layer for string-level control.
The battery management system (BMS) is not optional or add-on in RAKOUR products. It is a designed-in subsystem present at both cell-module and system levels. For LV units, a single BMS board manages the 16-cell pack. For HV configurations, each module carries a slave BMS, and the master logic resides in the Battery Control Unit (BCU), creating a two-tier architecture suited to high-voltage scalable battery storage strings.
Cell-Level Monitoring — Voltage, Current, Temperature
The BMS continuously measures individual cell voltage, pack current, and module temperature. It enforces charge cutoff at 57.9V and discharge cutoff at 46.4V. Overcharge, over-discharge, overcurrent, short-circuit, and high/low temperature protections are all hardware-enforced — not software-only flags. Cell balancing runs during the constant-voltage phase of charging to extend usable cycle life across the pack's lifespan.
Communication Protocols — CAN, RS485, RS232, WIFI
All RAKOUR products support CAN and RS485 communication as standard, with RS232 also available on LV models. The HV series adds optional WIFI for mobile remote monitoring. CAN is the primary protocol for inverter integration — verified for direct BMS-to-inverter handshake with DEYE series inverters, enabling automatic SOC reporting, charge current limiting, and fault relay commands without third-party BMS gateways.
Scalable Parallel Architecture — Up to 15 Units (LV) or 4 Sets (HV)
LV products support up to 15 units in parallel — each retaining its own BMS while the inverter arbitrates load sharing. HV products support up to 4 series strings in parallel. Expansion does not require re-wiring the base unit; additional modules are added to the existing rack or cabinet structure. This rack mount battery backup architecture allows capacity to be added incrementally as energy requirements grow.
OEM Battery Supplier Program — Custom Specifications and Wholesale Partnerships
Is it possible to OEM / customize?
RAKOUR supports OEM/ODM requests across all product lines, with a 5-year warranty on standard configurations.
RAKOUR operates as a direct energy storage manufacturer in China with OEM/ODM capability confirmed across the LV and HV product families. Buyers — whether system integrators, distributors, or EPC contractors — can engage on three levels: standard SKU wholesale, white-label rebranding, or full custom specification development. Engineering documentation is available upon request before any commercial commitment.
What Can Be Customized
Custom scope includes enclosure color and branding, communication protocol configuration (CAN/RS485 priority), display screen inclusion or removal, voltage and capacity tiers within the existing 51.2V LFP cell architecture, and packaging format for regional import compliance. The NSTLV wall-mounted catalog explicitly supports OEM/ODM, and the 314Ah-HV series accommodates rack or cabinet design variants for indoor and outdoor deployment.
Standard Warranty and Quality Assurance
All standard products carry a 5-year warranty. The NSTLV wall-mounted series is listed with a 5+5-year warranty structure. Quality documentation — including IEC62619 test reports, UN38.3 certificates, CE declarations, and MSDS — is issued per model and available for due-diligence review. Cycle life guarantees are tied to specific DoD conditions documented in the technical datasheet, not stated as unqualified marketing claims.
Grow your report
Buyers can initiate contact through the product inquiry form on this page or directly via the sales team. Specify the product series (LV Rackable, HV Rackable, or Wall-Mounted), target capacity in kWh, required certifications for the destination market, and whether OEM branding is needed.
