Great Power 75Ah 3.2V Grade A LiFePO4 Prismatic Battery Cell GSP27135206S – Ultra-Thin 27mm Profile – Lightweight 1.53kg Power for Portable Solar & Camping

Great Power 75Ah: The Ultra-Thin Energy Solution

The Great Power (PengHui Energy) GSP27135206S is a specialized 75Ah LiFePO4 cell engineered for applications where space is at a premium and weight is a critical constraint. By packing 75Ah of reliable capacity into an ultra-slim 27mm profile, it provides a unique building block for the next generation of portable power stations and space-efficient residential solar systems.

🚀 Key Advantages for Compact Builds

⚡ 27mm Ultra-Slim Profile: This cell is less than half the thickness of a standard 280Ah cell. This allows it to be stacked in incredibly tight spaces, such as behind solar panels, inside slim wall-mount enclosures, or within compact hand-held power station cases.
⚡ Lightweight Design (1.53kg): Weight matters for portable applications. At just over 1.5kg, this cell allows you to build a 12V 75Ah battery pack that weighs only ~6.2kg, making it significantly lighter than an equivalent lead-acid battery (~24kg).
⚡ Trusted Industrial Reliability: Manufactured by Great Power, a Top 3 global energy storage supplier, you can trust the consistency and safety of this cell. Rated for $\ge 2,000$ cycles, it offers a stable and long-term service life for backup and cycling needs.

🤝 Why Partner with DLCPO?

✅ Specific Model Guarantee: We supply the exact GSP27135206S model. DLCPO ensures you receive the correct 27mm thin version, which is critical for projects with strict dimensional constraints.
🎯 Quality Verification: Every cell is tested for voltage and ultra-low internal resistance ( $\le 0.7\text{ m}\Omega$ ) before leaving our warehouse. We ensure your cells are matched and ready for immediate assembly into balanced packs.
🌐 Hassle-Free Global Shipping: DLCPO specializes in professional DDP (Delivered Duty Paid) shipping to the USA, Europe, and Brazil. We manage all customs and Class 9 hazardous goods regulations, delivering high-quality lithium power directly to your door.

❓ Q:What are the exact dimensions for building a case?

💡 A:

The cell measures exactly 27mm thick, 135mm wide, and 205mm high. Please double-check your battery box dimensions to ensure fitment, especially the 27mm thickness which is its key advantage.

❓ Q:Can I use this to build a portable battery for camping?

💡 A:

Yes, it is excellent for camping. A 4S pack (12.8V 75Ah) provides nearly 1kWh of energy, enough to power lights, portable fridges, and charge multiple phones for a full weekend trip while remaining light enough to carry easily.

❓ Q:What is the recommended continuous discharge current?

💡 A:

For optimal lifespan and thermal performance, we recommend a continuous discharge of 0.5C (37.5A) to 1C (75A). This range covers most portable devices and small off-grid solar storage applications. 🚀

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.
Notice: Ultra-Thin Cell (27mm). Requires compression to prevent swelling. Max charge voltage 3.65V. Designed for storage applications.
