Industrial array of REPT CB51 150Ah battery cells on pallets, showcasing large-scale factory-fresh supply for B2B projects.

REPT CB51-150Ah: Performance in Extreme Conditions

The REPT CB51-150Ah stands out in the 150Ah class by offering rugged performance features usually found in specialized cells. Manufactured by REPT BATTERO, this LiFePO4 cell is engineered not just for capacity, but for versatility in challenging environments where temperature drops and power surges are common.

Key Performance Advantages

All-Weather Reliability: While standard LFP cells stop working at -20°C, the CB51-150Ah continues to discharge down to -30°C. This extended range is a game-changer for outdoor solar storage and vehicles in northern climates.
High Surge Capability: Rated for a Maximum Pulse Discharge of 450A (3C) for up to 60 seconds (SOC≥30%), this cell can effortlessly handle the startup loads of air conditioners, electric motors, and heavy tools without tripping BMS protections.
Compact & Efficient: With a precise thickness of 36.3mm ±0.5mm and low internal resistance (≤0.50mΩ), it allows for compact, cool-running battery packs with high volumetric energy density.

Genuine Grade A Guarantee: We provide authentic REPT cells directly from the manufacturer. No re-wraps, no B-grade. Just pure performance as specified in the datasheet.
Precision Matching: To ensure your pack performs flawlessly, especially under high 450A loads, we include Free Sorting Service. We match cells by voltage and impedance so they work in perfect harmony.
Global Hazardous Shipping: DLCPO is an expert in Class 9 dangerous goods logistics. We offer DDP (Delivered Duty Paid) shipping to the USA, Europe, and Brazil, handling all customs and safety protocols for you.

❓ Q:1: Can I charge this battery at freezing temperatures?

💡 A:

No. Like all LiFePO4 batteries, charging must occur above 0°C. However, you can discharge (use power) down to -30°C with a lower cutoff voltage of 2.0V.

❓ Q:2: What is the benefit of the 450A pulse rating?

💡 A:

It provides “headroom” for power spikes. If your inverter surges to start a heavy appliance, this battery can deliver the necessary current for a full minute without damage, provided the State of Charge is ≥30%

❓ Q:3:How does the cycle life compare to others?

💡 A:

It offers ≥3,000 cycles at 80% Depth of Discharge (DOD). While some storage-specific cells offer more, this is a standard rating for high-performance cells that balance power delivery with longevity.

Warnings & Cautions

1. Risk of fire, explosion, and burns. Do not disassemble, crush, heat the cell or dispose it
2. 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;
3. Replace the battery manufactured by the same manufacture only. Mixed use of battery from other manufacture might cause fire and explosion;
4. Do not throw the battery into water or make it wet;
5. Do not connect positive and negatives with metal cover;
6. Do not make the cell short circuit, over-charge or over-discharge;
7. Do not use or store the cell near the heat source (such as fire or heater):
8. Do not connect the position (+) and negative (-) terminals in the opposite way;
9. Do not put the battery together with coin, metal jewelry and other metal objects;
10. Do not puncture the battery by nail or other sharp objects. Hammering and crush the battery is forbidden;
11. Do not weld the battery directly;
12. 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;
13. Mixed use of different types, brand of battery are forbidden;
14. Do not connect the negative pole with the shell which is positive;
15. 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 cell handles 450A pulses (60s). Ensure wiring is rated for these surges. Do not charge below 0°C without heating. Operating range is -30°C to 55°C.
