Lishen LP71173207 280Ah: The Industrial Energy Pillar The Lishen LP71173207-280Ah is a cornerstone in the global transition to renewable energy. As an automotive-grade Lithium Iron Phosphate (LiFePO4) cell, it is meticulously designed to meet the high-demand requirements of utility storage and industrial electric mobility. With nearly 1kWh of energy per cell, it is the gold standard for high-density battery projects.

🚀 Unrivaled Technical Efficiency

Precision Low Resistance: Featuring an ultra-low internal resistance of under 0.2 mΩ, the LP71173207 minimizes energy loss during high-current cycling, resulting in cooler operation and higher overall system efficiency.
Massive Energy Capacity: The 280Ah capacity allows for the construction of high-energy battery banks with fewer parallel connections, simplifying your BMS management and reducing potential points of failure.
Robust Cycle Life: Engineered for extreme durability, it provides over 2,000 cycles at 1C rates (and significantly more at 0.5C), translating to over 10-15 years of daily use in typical solar energy storage environments.

🤝 Why Partner with DLCPO?

✅ Verified Grade A Quality: We supply 100% original Lishen cells. Every unit is tested for capacity and internal resistance consistency before shipping to ensure perfectly balanced battery modules.
🎯 Original QR Codes Intact: We never deal in relabeled or scratched cells. You get full traceability for every batch, giving you confidence in the manufacturing date and authenticity of the cells.
🌐 Global Shipping Expertise: DLCPO specializes in DDP (Delivered Duty Paid) shipping to Brazil, USA, and Europe. We handle all customs formalities and lithium battery safety protocols, delivering directly to your door.

❓ Q:Is this the standard 280Ah size used in other brands?

💡 A:

Yes. It follows the industry-standard dimensions of 173.6mm x 71.25mm x 207.05mm. This makes it fully compatible with most standard 280Ah battery enclosures and pre-made busbars on the market.

❓ Q:Can I use this for my campervan or boat?

💡 A:

Absolutely. The 280Ah size is a favorite for RV and Marine enthusiasts who want to build a “forever battery” that can run air conditioners and induction cooktops with ease.

❓ Q:Does it support fast charging?

💡 A:

It supports a standard 1.0C charge rate (280A). While fast, we recommend a 0.5C (140A) rate for daily solar use to further extend the cell’s lifespan to its maximum potential.

Warnings & Cautions

1. Avoid overheat in any circumstances. Don’t modify or disassemble the battery. It will be dangerous, and may cause ignition, heating, leakage or explosion.
2. Don’t put cells in overheat circumstances or disposed in fire ,don’t put cells under the sunshine.
3. Don’t short-circuit positive(+) and negative(-) terminals. Keep away from metal or other conductive materials. Jumbling the batteries of direct contact with positive(+) and negative(-) terminals or other conductive materials may cause short-circuit and may even cause fire and explosion.
4. Don’t reverse the positive (+) and negative (-) terminals.
5. Don’t put cells in water or other conductive liquids or let cells absorb a moisture.
6. Don’t impact cells excessively.
7. Don’t solder the battery directly. Excessive heating may cause deformation of the battery components such as the gasket, which may lead to the battery swelling, leakage, explosion, or ignition.
8. Don’t use abnormal cell which has damages by shipping stress, drop, short or something else, and which gives off electrolyte odor.
9. Don’t contact cans directly or with other conductive materials during the using process.
10. Keep away form static circumstances during storage and using.
11. Don’t use cells together with other one-shot batteries and secondary batteries. Don’t use cells together with different packages, types and brands.
12. Stop using and process the cells accordingly when the following circumstances happened：getting hot sharply, smelling, changing colors, deformation or others.
13. If there is leaked electrolyte from batteries, please scrub it away with fresh water to avoid any skin discomfort.
14.Notice: This cell weighs over 5kg; ensure proper structural support in your battery enclosure. For maximum lifespan, maintain charging temperatures above 0°C and use proper cell compression.
