12 AH 12.8V LiPo4 Battery Pack

Product Description

1. Capacity:

Nominal Capacity: 12Ah (12,000mAh)

Usable Capacity: Around 95-100% of the nominal capacity due to high efficiency.

2. Voltage:

Nominal Voltage: 12.8V

Maximum Charging Voltage: 14.6V

Cut-off Voltage: 10.0V to 11.0V (depends on the battery management system)

3. Discharge Rate:

Continuous Discharge Current: Varies by manufacturer, often between 10A to 30A.

Peak Discharge Current: Can handle short bursts, often 2-3 times the continuous discharge rate (e.g., 40A to 60A for a few seconds).

Discharge Cut-off Voltage: 10.0V to 11.0V.

4. Charging Parameters:

Recommended Charging Current: Typically 0.2C to 0.5C (2.4A to 6A).

Maximum Charging Current: Often 1C (12A).

Charging Temperature Range: 0C to 45C.

Charging Method: CC/CV (Constant Current/Constant Voltage).

5. Operating Temperature:

Discharge Temperature Range: -20C to 60C.

Storage Temperature Range: -20C to 45C (for short-term storage).

Optimal Operating Temperature: 15C to 35C.

6. Cycle Life:

Cycle Life: 2000 to 5000 cycles at 80% depth of discharge (DoD), depending on quality and usage conditions.

7. Dimensions and Weight:

Dimensions: Can vary by manufacturer, but a typical size is about 150mm x 65mm x 95mm.

Weight: Approximately 1.5kg to 2.5kg.

8. Internal Protection:

Battery Management System (BMS): Typically integrated to protect against overcharge, over-discharge, over-current, and short-circuit conditions.

Balancing: Often includes cell balancing during charging to ensure all cells are evenly charged.

9. Safety Features:

Thermal Fuse: For protection against overheating.

Pressure Relief Vent: To release gases if overcharged.

Non-toxic and environmentally friendly: LiFePO4 batteries are known for being more environmentally friendly compared to other lithium-ion batteries.

10. Applications:

Common Uses: Solar energy storage, electric vehicles, marine applications, backup power systems, and portable electronics.
