REPT CB75-314Ah: The New Benchmark in Energy Density

The REPT CB75-314Ah represents a significant leap forward in Lithium Iron Phosphate technology. By optimizing the internal structure and active materials, REPT has packed 314Ah of capacity into a form factor traditionally used for 280Ah cells. With over 1,004Wh of energy per single cell, it allows you to build smaller, lighter, and longer-lasting battery banks.

Why Upgrade to 314Ah?

12% More Energy: Compared to standard 280Ah cells, the 314Ah model provides significantly more runtime. A standard 16S 48V pack jumps from roughly 14.3kWh to over 16kWh of usable storage.
8,000+ Cycle Life: Engineered for durability, the CB75 is rated for over 8,000 charge/discharge cycles. In a daily solar storage application, this translates to potential service life exceeding 15-20 years.
Superior Energy Density: Achieving 175Wh/kg and 394Wh/L, this cell maximizes every millimeter of space, making it the superior choice for space-constrained RVs and boats.

Why Partner with DLCPO?

Genuine Grade A Inventory: We supply 100% original REPT cells directly from the factory line. Each cell features intact QR codes for complete traceability.
Precision Matching: We perform rigorous capacity, voltage, and internal resistance (≤0.3mΩ) testing on every cell to ensure your high-capacity pack is perfectly balanced.
Global Shipping Authority: DLCPO specializes in DDP (Delivered Duty Paid) shipping for heavy lithium batteries to the USA, Europe, and Brazil, handling all dangerous goods logistics for you.

❓ Q:1: Is this the same size as a 280Ah cell?

💡 A:

It is very similar but not identical. The width (174mm) and height (207mm) are standard, but the thickness is 71.7mm. Please check your battery compression fixture to ensure it can accommodate this slight difference.

❓ Q:2: Can I mix these with 280Ah cells?

💡 A:

No. You should never mix cells of different capacities or ages in the same battery bank, as this will lead to imbalance and reduced system performance.

❓ Q:3: What busbars should I use?

💡 A:

Given the high capacity, we recommend high-quality flexible busbars rated for at least 300A to handle potential current loads efficiently without heating.

Warnings & Cautions

Risk of fire, explosion, and burns. Do not disassemble, crush, heat the cell or dispose it
Keep the cell out of reach of children and don’t remove the original package before use. Dispose the used battery according to local recycling or waste disposition regulations;
Replace the battery manufactured by the same manufacture only. Mixed use of battery from other manufacture might cause fire and explosion;
Do not throw the battery into water or make it wet;
Do not connect positive and negatives with metal cover;
Do not make the cell short circuit, over-charge or over-discharge;
Do not use or store the cell near the heat source (such as fire or heater):
Do not connect the position (+) and negative (-) terminals in the opposite way;
Do not put the battery together with coin, metal jewelry and other metal objects;
Do not puncture the battery by nail or other sharp objects. Hammering and crush the battery is forbidden;
Do not weld the battery directly;
Do not disassemble or modify the battery in any way; 13)Do not hit, throw or subject the battery to mechanical vibration and free fall;
Mixed use of different types, brand of battery are forbidden;
Do not connect the negative pole with the shell which is positive;
Stop use the battery and relocate the battery to a safe place it if battery gives off peculiar smell, temperature increase, deforms, color change or any other abnormal phenomena. 17)If battery leaks, and electrolyte enters into eyes, do not rub. Rinse with clean running water, and seek medical assistance immediately; 18)If battery catch fire, use dry powder, foam fire extinguisher or sand to extinguish flames and remove it from the operating environment;
Notice: This 314Ah cell is slightly thicker (71.7mm) than standard 280Ah cells. Please verify your fixture compression and battery box dimensions. Charging below 0°C requires pre-heating.
