ETPL 40Ah 3.2V Grade A LiFePO4 Prismatic Battery Cell EFP27148130 – Ultra-Slim 27mm Design – Automotive-Grade LFP for Portable Power & Robotics

Four blue Lixin Energy 40Ah LiFePO4 prismatic cells arranged for a lightweight 12.8V 40Ah lithium battery pack build.

ETPL 40Ah: Automotive Grade in a Compact Package

The ETPL 40Ah LiFePO4 Cell (Model EFP27148130) brings automotive manufacturing standards to the compact battery market. As a subsidiary of the prestigious Geely Technology Group (the same parent company as Volvo and Lotus), Lixin Energy produces cells with exceptional thermal stability and safety standards that far exceed standard consumer-grade batteries.

🚀 Key Features for Compact Builds

⚡ Ultra-Slim Design (27mm): At just 27mm thick, this cell is exceptionally slender compared to typical 100Ah/200Ah models. It is perfect for flat battery packs, thin robot chassis, or behind-the-panel solar storage.
⚡ Reliable Automotive Pedigree: Engineered for the demanding EV market, these cells maintain reliable discharge performance across a wide temperature range ( $-20^\circ\text{C}$ to $50^\circ\text{C}$ ) and are rated for ≥ $\ge 2,000$ full cycles.
⚡ Perfect for 12V/24V Packs: A 4-cell series configuration (4S) creates a lightweight 12V 40Ah battery weighing just over 4kg. This is an ideal, durable replacement for heavy 12V lead-acid batteries in fishing finders and camping gear.

🤝 Why Partner with DLCPO?

✅ Source Transparency: We correctly identify every cell. When you buy from DLCPO, you know you are receiving a genuine Lixin Energy (Geely Group) product with verified automotive-tier quality.
🎯 Quality Verification: We test internal resistance (≤ $\le 0.8\text{ m}\Omega$ ) and voltage on every unit before shipment. Since small packs often lack active balancing, starting with matched cells is crucial for long-term reliability.
🌐 Safe & Compliant Shipping: Even small lithium batteries are hazardous goods. DLCPO provides fully compliant DDP (Delivered Duty Paid) shipping to the USA, Europe, and Brazil, handling all UN3480 safety protocols for you.

❓ Q:Who is Lixin Energy?

💡 A:

Lixin Energy was founded in 2016 and is part of the Geely Technology Group. They specialize in high-tech lithium-ion battery production for EVs and high-end energy storage systems, leveraging the same engineering standards used for luxury car brands.

❓ Q:What are the exact dimensions for my enclosure design?

💡 A:

The cell body measures 148mm wide, 130mm high, and 27.5mm thick. Please note that the total height including the terminals will be slightly more (approx. 132.6mm). Its slender 27mm profile is its greatest mechanical advantage.

❓ Q:Can I use this as a starter battery for a car?

💡 A:

No. This cell is designed for deep cycle storage and traction (0.5C to 1C discharge). While it can handle short pulses, it is not optimized for the massive cold cranking amps (CCA) required to start large gasoline or diesel engines. 🔋

Warnings & Cautions

Avoid overheat in any circumstances. Don’t modify or disassemble the battery. It will be dangerous, and may cause ignition, heating, leakage or explosion.
Don’t put cells in overheat circumstances or disposed in fire ,don’t put cells under the sunshine.
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.
Don’t reverse the positive (+) and negative (-) terminals.
Don’t put cells in water or other conductive liquids or let cells absorb a moisture.
Don’t impact cells excessively.
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.
Don’t use abnormal cell which has damages by shipping stress, drop, short or something else, and which gives off electrolyte odor.
Don’t contact cans directly or with other conductive materials during the using process.
Keep away form static circumstances during storage and using.
Don’t use cells together with other one-shot batteries and secondary batteries. Don’t use cells together with different packages, types and brands.
Stop using and process the cells accordingly when the following circumstances happened：getting hot sharply, smelling, changing colors, deformation or others.
If there is leaked electrolyte from batteries, please scrub it away with fresh water to avoid any skin discomfort. 14.Notice: Thin Cell (27mm). Requires compression to prevent swelling. Max Charging Voltage: 3.65V. Ensure proper BMS protection.
