Great Power 100Ah: Capacity Meets Slim Design

The Great Power (PengHui Energy) GSP27135250F represents a new frontier in space-efficient battery engineering. While standard 100Ah LiFePO4 cells are often too bulky for modern portable and mobile applications, the GSP series delivers full capacity in a remarkably slender form factor that opens up new possibilities for system integrators and DIY enthusiasts alike.

🚀 Key Design Features

⚡ 27mm Ultra-Thin Profile: At just $27\text{ mm}$ thick, this cell is exceptionally slender compared to the typical 34mm-48mm industry standards. It is the perfect choice for flat battery packs, such as behind-the-seat RV installations or inside slim portable power station casings.
⚡ High Energy Density: Weighing only $1.97\text{ kg}$ , this cell achieves a high energy-to-weight ratio. A 12V 100Ah pack built with these cells weighs significantly less than traditional prismatic builds, offering massive weight savings for mobile platforms.
⚡ Proven Industrial Quality: As a Top 3 energy storage manufacturer, Great Power ensures every cell meets strict industrial standards. With a verified cycle life of $\ge 2,000$ cycles, it provides reliable, safe power for years of rigorous operation.

🤝 Why Partner with DLCPO?

✅ Exact Model Verification: We supply the specific GSP27135250F model. DLCPO ensures you get the exact tall ( $250\text{ mm}$ ), thin ( $27\text{ mm}$ ) version designed for your specific spatial requirements.
🎯 Performance Testing: We test internal resistance ( $\le 0.7\text{ m}\Omega$ ) and voltage on every cell. This ensures that when you connect them in series or parallel, they work in harmony without premature imbalance or overheating.
🌐 Global Logistics Expertise: DLCPO is an expert in shipping lithium batteries. Our DDP (Delivered Duty Paid) service handles all customs, taxes, and dangerous goods regulations for shipments to the USA, Europe, and Brazil.

❓ Q:Q: What are the exact dimensions of this 100Ah cell?

💡 A:

The cell is $27\text{ mm}$ thick, $135\text{ mm}$ wide, and $250.5\text{ mm}$ tall. Please note that the height is taller than standard cells, so ensure your battery box or compartment has the necessary vertical clearance.

❓ Q:How much will a 12V 100Ah pack weigh?

💡 A:

You need 4 cells in series. The resulting pack would weigh approximately $7.9\text{ kg}$ (excluding casing and BMS), making it one of the lightest 100Ah LFP solutions available for portable or camping use.

❓ Q:Is this cell suitable for a trolling motor?

💡 A:

Yes, provided the continuous discharge does not exceed the cell’s rating (typically 0.5C-1C). Its lightweight design makes it excellent for small boats where reducing the overall load is critical for performance. 🚤

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 uniform compression to prevent swelling. Max charge voltage 3.65V. Verify 250mm height fits your box.
