REPT CB71173200EA-280Ah : Efficiency Redefined

The REPT CB71173200EA-280Ah is a high-specification Lithium Iron Phosphate (LiFePO4) cell. It stands out in the crowded 280Ah market due to its exceptional manufacturing quality, boasting one of the lowest internal impedance ratings in its class.

Key Technical Highlights

Ultra-Low Internal Resistance: With an AC impedance of just 0.1 ~ 0.3 mΩ, this cell is significantly more efficient than standard cells (typically 0.25-0.5 mΩ). This means less energy is wasted as heat during charging and discharging, resulting in a cooler, longer-lasting battery bank.
High Surge Capability: Rated for a Maximum Pulse Discharging Current of 560A, it provides the instantaneous power needed for starting heavy inductive loads like air conditioners and pumps.
Grade A Consistency: As a genuine Grade A cell from REPT BATTERO, it guarantees consistent capacity and voltage performance, essential for building large serial/parallel battery banks.

❓ Q:1: What is the cycle life of this model?

💡 A:

Like most premium 280Ah LFP cells, it is designed for long-term service, typically rated for ≥6,000 cycles at 0.5C charge/discharge rates under standard compression.

❓ Q:2: Can I use this for a 48V system?

💡 A:

Yes. 16 cells connected in series (16S) will create a 51.2V 280Ah battery pack with a total energy storage of approximately 14.3 kWh.

❓ Q:3:Why is low internal resistance important?

💡 A:

Lower resistance means less voltage drop under load. This keeps your inverter running longer before hitting the low-voltage cutoff, effectively giving you more usable capacity during high-power usage.

Warnings & Cautions

Stop charging cells if charging isn’t completed within the specified time.

Stop using cells if the battery becomes abnormally hot, develops an odor, becomes discolored, deformed, or develops any other abnormal conditions during use, charge, discharge, or storage.

Keep away from fire or hot heat sources immediately when a leakage or foul odors are detected. If liquid leaks onto your skin or cloths, wash it out with plenty of fresh water immediately if liquid leaks from cells and gets into your eyes, don’t rub your eyes. Wash your eyes out with plenty of clean water and seek medical attention immediately

Notice: Cells must be compressed (12-15psi) for optimal cycle life. Ensure busbars are rated for 280A continuous current. Charge only above 0°C.
