Purchasing Guide – How to Choose Your Configuration

Tip: For larger capacity, connect multiple parallel strings – each additional string adds 280Ah of capacity at the same voltage.

Instructions for Use & Precautions

Step 1: Cell Inspection

• 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

Step 2: Series/Parallel Connection

• 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

Step 3: BMS Integration

• 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

Step 4: Charging

• 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

Step 5: Storage & Maintenance

• 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

Frequently Asked Questions (FAQ)

Q1: Are these genuine Grade A new cells?

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.

Q2: What is the actual capacity of the EVE LF280K?

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.

Q3: How many cells do I need for a 12V / 24V / 48V system?

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.

Q4: What is the difference between LF280K V2 and V3?

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.

Q5: Do I need a BMS (Battery Management System)?

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.

Q6: Do you test cells before shipping? How do you match them?

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.

Q7: Are busbars and screws included?

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.

Q8: What certifications do these batteries have?

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.

Q9: What is the warranty and replacement policy?

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.

Q10: How are the batteries shipped? Do you have EU stock?

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.

Q11: Can I use these cells in a marine/boat application?

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.

Q12: Can you customize battery packs?

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.

Q13: Do you offer other battery accessories?

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.

Q14: Why can't I see tracking updates for weeks?

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.
