201Ah‑304Ah LiFePO4 Cells

201Ah–304Ah LiFePO₄ Cells – The High‑Capacity Workhorse for Utility‑Scale Storage & Heavy‑Duty Electric Powertrains

Welcome to our 201Ah–304Ah LiFePO₄ Cells collection. When your project demands maximum energy per cell and the lowest possible system complexity, the 201Ah to 304Ah class is the undisputed workhorse of the lithium iron phosphate world. While 100–150Ah cells remain the go‑to for compact 12V drop‑ins and light mobility, these larger cells – each weighing 4.0–5.5 kg and storing up to 970 watt‑hours – slash the number of parallel strings required for serious storage. A single 16‑cell string of 280Ah units delivers a 51.2V 280Ah (14.3 kWh) residential battery module that covers the daily consumption of most households, with no parallel connections needed. Scale that to a commercial 20‑foot container, and 201–304Ah cells become the core building block for utility‑scale energy storage, industrial backup, heavy‑duty electric vehicles, marine propulsion, and off‑grid microgrids – where reliability, cycle life, and levelised cost of storage matter most.

Every cell in this collection is a genuine Grade‑A prismatic unit from the world's most established manufacturers – EVE Energy, CATL, REPT, CALB, and Gotion High‑Tech. Whether you are deploying a 100 kWh commercial ESS cabinet, retrofitting a diesel‑electric ferry, powering an electric city bus, or engineering a high‑voltage UPS for a data centre, this is your direct source for the cells that define the modern energy storage industry.

Core Advantages of 201–304Ah Cells

• Fewer Cells, Higher System Reliability: A single 280Ah cell contains the energy of almost three 100Ah cells. Building a 14.3 kWh 48V battery requires only 16 cells instead of 32 (using 100Ah), dramatically reducing the number of busbar connections, voltage sense wires, and potential failure points. For large‑scale deployments, this reduction in component count translates directly into higher system uptime and lower assembly costs.
• Industry‑Standard for Residential & Commercial Storage: The 51.2V 280Ah (14.3 kWh) module – built from 16 EVE LF280K or CATL 280Ah cells – has become the de‑facto reference design for wall‑mount and rack‑mount home batteries, as well as small commercial peak‑shaving units. Two to four such modules in parallel create a 28–57 kWh system that integrates seamlessly with all major hybrid inverter brands, while still being transportable and serviceable by a single technician.
• Exceptional Cycle Life & Ultra‑Low LCOS: Modern 201–304Ah LiFePO₄ cells are engineered for 6,000–10,000 cycles at 80% depth of discharge, with some models pushing beyond 10,000 cycles under optimal conditions. This translates into a calendar life exceeding 15–20 years in daily cycling applications, driving the levelised cost of storage (LCOS) down to figures that compete with – and increasingly undercut – pumped hydro and new gas peaker plants.
• Heavy‑Duty Power Delivery: Despite their high capacity, mainstream 280–304Ah cells support 0.5C–1C continuous discharge (140–304 A), with peak rates of 2C in power‑optimised variants. This is sufficient to drive commercial EV motors, containerised battery‑to‑grid systems, and backup power for entire hospital wings – all while retaining the inherent thermal stability and safety of the LiFePO₄ cathode.

How to Choose the Right 201Ah–304Ah Cell?

⚠️ 201Ah–304Ah Cell Safety Guidelines

• BMS is Absolutely Mandatory: A 280Ah cell can deliver fault currents exceeding 3,000 A. Every series pack must use a properly rated BMS with per‑cell voltage monitoring, overcharge protection (>3.65V), over‑discharge cut‑off (<2.5V), short‑circuit protection, and active or passive balancing. Redundant protection layers are strongly recommended for mission‑critical systems.
• Low‑Temperature Charging is Strictly Prohibited: Charging these cells below 0°C causes immediate and irreversible lithium plating damage. In outdoor installations, battery enclosures must include integrated heating elements and a BMS with low‑temperature charge lockout to prevent operation outside the safe window.
• Professional‑Grade Terminal Connections: At continuous currents of 140–300 A, terminal connections become a critical safety element. Use only nickel‑plated copper busbars sized for the maximum continuous current, fastened with high‑grade stainless steel bolts torqued to the manufacturer's exact specification (typically 6–8 Nm for M6 terminals). Regular thermal imaging inspections are advised for large installations.
• Cell Compression Fixtures are Essential: Large prismatic cells must be assembled with rigid end plates and calibrated compression (typically 300–500 kgf) to maintain uniform internal pressure over thousands of cycles. Failure to apply proper compression leads to delamination, swelling, and accelerated capacity fade. Always use FR‑4 insulation between cells and compression foam for vibration isolation.
• Storage and Transport Voltage: Cells should be stored and shipped at 3.20–3.30V per cell (≈30–50% SOC). Large‑capacity cells hold significant residual energy even at low SOC – always treat terminals as live and use insulated tools during assembly.

Why Choose Our 201Ah–304Ah LiFePO₄ Cells?

• Factory‑Direct Grade‑A Cells: We supply only new, authentic cells directly from EVE, CATL, REPT, CALB, and Gotion, with original factory QR codes and full batch traceability. Every shipment includes corresponding test data – we never touch grey‑market, reclaimed, or B‑grade cells.
• Precision Sorting for Multi‑String Systems: Our cells are voltage, capacity, and internal‑resistance binned to ±25mV voltage tolerance and ±5mΩ IR deviation. For large parallel‑string installations, this matching ensures balanced current sharing and prevents premature ageing of individual cells.
• Complete Build‑of‑Materials Supply: We stock and supply the full accessory ecosystem: laser‑welded and flexible busbars, stainless steel fasteners, FR‑4 insulation sheets, cell holders, compression plates, and compatible smart BMS units from leading brands – ready to ship with your cells.
• Scalable Purchasing & Custom Engineering: From single‑cell evaluation samples to container‑load deliveries, we support projects of every scale. Our in‑house engineering team offers custom services including stud welding, busbar assembly, pre‑compressed module assembly, and full battery pack manufacturing.
• Technical Partnership from Design to Deployment: Our engineers work with you to optimise cell selection, system architecture, thermal management, and BMS configuration. We provide detailed cell datasheets, 3D models, and ongoing after‑sales support to ensure your system performs reliably for its entire design life.
