OID 48173125L100AH 3.2V 100Ah LiFePO4 Battery Cell with 3000 Cycles and 1C Continuous Discharge for EV/ESS

The Jianheng OID 48173125L100AH is a high-performance 3.2V 100Ah prismatic lithium iron phosphate (LiFePO4) battery cell. Engineered for demanding applications such as electric vehicles (EVs), renewable energy storage systems (ESS), and industrial equipment, this cell offers exceptional cycle life, thermal stability, and safety. With a nominal capacity of 100Ah and a robust aluminum housing, it delivers reliable power under a wide range of operating conditions.

• High Safety: LiFePO4 chemistry ensures excellent thermal and chemical stability, reducing the risk of thermal runaway.
• Long Cycle Life: 3000 cycles at 80% depth of discharge (DoD) under standard conditions.
• High Current Capability: Supports 1C continuous charge and discharge, with peak pulse currents for regeneration.
• Wide Temperature Range: Operates from -20°C to 60°C (discharge) and 0°C to 60°C (charge).
• Low Internal Resistance: ≤0.40mΩ (1kHz AC), enabling high efficiency.
• Precision Dimensions: 47.8±0.5mm (Thickness) x 174.2±0.8mm (Width) x 132.3±0.8mm (Height).

The cell features an aluminum case with a positive potential. The terminal is M6 threaded (pitch 1.0mm) for secure connection. The top cover includes a safety vent. Detailed dimensions and appearance standards (scratches, stains, etc.) are strictly controlled per factory specifications.

This LiFePO4 cell is designed with multiple safety features. A Battery Management System (BMS) is mandatory for operation to monitor voltage, current, and temperature. The BMS must enforce charging cut-off at 3.65V, discharging cut-off at 2.50V (or 2.00V at low temperature), over-current protection, and temperature limits to ensure safe operation and warranty validity.

For optimal cycle life and safety testing, a preload force of 500N to 5000N is recommended, with a tolerance of ±200N. During its lifespan, the cell can generate swelling forces up to 30000N at 80% SOH, so structural design should accommodate this.

No. Using this cell without a Battery Management System (BMS) is strictly prohibited. A BMS is essential for monitoring voltage, current, and temperature to prevent overcharge, over-discharge, short circuits, and overheating, which can cause permanent damage or safety hazards.

For storage exceeding 30 days, maintain the state of charge (SOC) between 25% and 40% and store in a cool, dry place (-30°C to 35°C for 6 months). For storage beyond 3 months, a full charge-discharge cycle every 3 months is recommended to maintain capacity.

Under standard conditions (1C charge/discharge at 25°C with appropriate clamping force), the cell retains ≥80% of its initial capacity after 3000 cycles.

The recommended torque varies by bolt grade. For a Grade 8.8 bolt, the torque is 10.5 N·m with an allowable deviation of ≤5%. Please refer to the full torque table in the specification for other bolt grades.

Yes, it can discharge at temperatures as low as -20°C. However, charging at temperatures below 0°C is not allowed. Special low-temperature charging profiles are detailed in the specification (see Section 2.2.8).

This cell is manufactured in compliance with industry safety standards. It is a LiFePO4 cell with inherent safety advantages. Please contact Jianheng for specific certification documents (e.g., UL, UN38.3) available for this model.

In case of electrolyte leakage, avoid contact with skin and eyes. Use protective equipment. If contact occurs, rinse with plenty of water and seek medical attention. Damaged cells should be isolated and disposed of according to local regulations.
