Every EVE LF280K battery cell is 100% brand new Grade A+ with an intact original QR code for traceability. Unlike grey-market cells from other manufacturers, EVE maintains an official distribution channel ensuring authentic Grade A quality. Each cell is factory-direct with full traceability back to the production line.
With an AC internal resistance of ≤0.25mΩ, the EVE LF280K delivers exceptional power efficiency and minimal energy loss during charge and discharge. The cell supports 1C continuous charge and discharge (280A), making it suitable for high-power applications including electric vehicles, solar storage, and backup power systems.
The EVE LF280K V3 offers an industry-leading cycle life – ≥6000 cycles at 25°C with 0.5C/0.5C charge/discharge, and up to 8000 cycles at 70% State of Health (SOH). This translates to over 15 years of reliable service in typical solar applications, significantly outlasting lead-acid batteries and many competing lithium cells.
This LFP battery cell operates across a broad temperature spectrum: charging from 0°C to 55°C and discharging from -20°C to 55°C. With a capacity retention rate ≥80% even in extreme conditions, the EVE LF280K delivers dependable performance whether installed in a hot solar farm or a cold-weather RV.
Lithium Iron Phosphate (LiFePO4) chemistry provides inherent safety – no thermal runaway risk, no explosive gases, and no cobalt, nickel, or mercury. The EVE LF280K complies with RoHS and halogen-free standards and is certified with UN38.3, CE, and MSDS for safe international transport and use.
The EVE LF280K is the go-to choice for DIY battery builders. Configure 4 cells in series for 12V, 8 cells for 24V, or 16 cells for 48V systems. Each cell comes with busbars and screws included, and the aluminum prismatic form factor makes assembly straightforward. Busbar tightening torque: 5–6 Nm.
With warehouses in Europe, we offer fast delivery and DDP (Delivered Duty Paid) shipping – all taxes and customs clearance included. No hidden fees, no customs delays. Tracking updates are provided once the package arrives in your country.
The EVE LF280K 280Ah LiFePO4 battery cell is widely used in:
| Application | Description |
|---|---|
| Solar Energy Storage | Home solar systems, off-grid and hybrid installations |
| ESS (Energy Storage Systems) | Grid-scale and commercial energy storage |
| RV & Motorhome | 12V/24V house battery banks for recreational vehicles |
| Marine & Yacht | Reliable starting and house power for boats |
| UPS (Uninterruptible Power Supply) | Backup power for critical equipment |
| Low-Speed Electric Vehicles | Golf carts, rickshaws, forklifts |
| Lead-Acid Replacement | Direct drop-in replacement for SLA batteries |
LiFePO4 batteries do not emit explosive gases – a major safety advantage in enclosed marine and RV environments compared to lead-acid batteries.
| System Voltage | Cells Needed | Configuration | Typical Use |
|---|---|---|---|
| 12V | 4 cells | 4S | RV, marine, small solar |
| 24V | 8 cells | 8S | Medium solar, golf carts |
| 48V | 16 cells | 16S | Home solar ESS, off-grid |
| Higher Capacity | Multiple parallel strings | nP + mS | Large-scale storage systems |
Tip: For larger capacity, connect multiple parallel strings – each additional string adds 280Ah of capacity at the same voltage.
Check each cell for physical damage upon arrival
Verify voltage and internal resistance match within specification
Voltage deviation should be < 0.01V; resistance deviation < 0.1mΩ
Use the included busbars and screws
Tighten busbar nuts to 5–6 Nm torque
Apply threadlocker to the screws to prevent loosening.
Do not over-tighten – this can damage terminals
A Battery Management System (BMS) is always required
The BMS must be designed for LiFePO4 chemistry
Ensure BMS supports the correct series count (4S/8S/16S) and has adequate current rating with safety margins
Use a charger compatible with LiFePO4 chemistry
Charge voltage: 3.65V per cell
Charge current: 0.5C standard, up to 1C maximum
Never use a lead-acid charger unless confirmed compatible
Store at 30% – 50% SOC for long-term storage
Storage temperature: 0°C ~ 35°C (long-term)
Charge and discharge every 6 months during storage
Keep in dry, clean environment away from corrosive substances
Precautions:
Do not short-circuit the battery terminals
Do not install with incorrect polarity
Do not mix different models or manufacturers
Do not disassemble or modify the cell
Wear rubber gloves when handling batteries
In case of leakage, smoke, or damage, stop using immediately and contact us
A: Yes, 100% brand new Grade A+ cells with intact original QR codes for full traceability. We source directly from EVE Energy’s official channel – no grey-market or B-grade cells.
A: While rated at 280Ah, Grade A EVE LF280K cells typically deliver 300–305Ah in actual testing. EVE is conservative in their ratings, and our cells consistently exceed nominal capacity.
A: For 12V you need 4 cells in series (4S); for 24V you need 8 cells (8S); for 48V you need 16 cells (16S). For more capacity, add parallel strings.
A: The V3 version offers increased cycle life – from 6,000 to 8,000 cycles at 70% SOH. Actual capacity is also slightly higher. We always ship the latest version.
A: Yes, absolutely. A BMS is always required for LiFePO4 battery packs. The BMS monitors cell voltage, current, temperature, provides cell balancing, and protects against overcharge, over-discharge, overcurrent, and short circuits. The BMS must be designed for LiFePO4 chemistry and support your series configuration.
A: Yes. Every cell is strictly tested for capacity, voltage, and internal resistance before shipment. Voltage deviation is kept < 0.01V, resistance deviation < 0.1mΩ, and capacity deviation ≤ 5% within the same batch. High internal resistance cells are rejected.
A: Yes. Every cell comes with busbars and screws included at no extra cost. For example, if you order 4 cells, you receive 4 busbars and 8 screws.
A: The EVE LF280K is certified with UN38.3 (required for all lithium battery shipments), CE, and MSDS. LiFePO4 chemistry is RoHS compliant and contains no cobalt, nickel, or mercury.
A: We offer a 1-year warranty from the date of successful delivery. If cells arrive damaged – despite our 5-layer thick foam and hardest carton packaging – we provide 100% new replacement within one business day. All packages are inspected by three staff members before shipping.
A: Yes, we have EU warehouse stock for fast delivery. We ship with DDP (Delivered Duty Paid) – all taxes and customs clearance included. Batteries are shipped at 30% – 40% SOC for safety. Tracking updates appear once the package arrives in your country. Shipping time to EU: approximately 3–7 days.
A: Yes. The EVE LF280K is very popular for marine installations. The cells handle vibration well, and with a waterproof battery box and proper BMS, you get a compact, lightweight, and powerful system. LiFePO4 does not emit explosive gases – a major advantage in enclosed boat environments compared to lead-acid batteries.
A: Yes. We offer custom battery pack assembly. Please provide: voltage, capacity, application, constant and peak charge/discharge current, size limitations, and any other relevant requirements.
A: Yes. We are a one-stop power provider – we also supply active battery balancers, smart BMS, chargers, and other accessories to help you save time and money.
A: This is normal. The tracking number won't update until the package arrives in your country. While in transit (e.g., on a train or ship), no tracking is available. Please be patient – your package is on its way.
