26650 3.2V 4000mAh Deep Cycle Lithium Iron Phosphate Battery 

 Features

1. Exceptional Safety: LiFePO4 chemistry is highly stable, resistant to thermal runaway, and non-combustible under normal conditions.

2. Long Cycle Life: Capable of over 2000 charge-discharge cycles while maintaining 80% capacity.

3. High Energy Density: Provides substantial power in a compact form factor.

4. Wide Temperature Range: Performs reliably in both high and low temperature environments.

5. Environmentally Friendly: Contains no toxic heavy metals (lead, cadmium, mercury).

6. Low Self-Discharge: Maintains charge for extended periods when not in use.

7. No Memory Effect: Can be recharged at any state of charge without capacity reduction.

Usage precautions and safety warnings

Charging Precautions:

• Use only chargers specifically designed for LiFePO4 chemistry

• Never exceed maximum charging voltage of 3.65V

• Do not charge at temperatures below 0°C or above 45°C

• Discontinue use if battery becomes hot, swollen, or damaged during charging

Discharging Precautions:

• Avoid deep discharge below 2.5V

• Do not exceed maximum continuous discharge current of 4A

• Never short-circuit the battery terminals

• Allow battery to cool between high-drain applications

Storage & Handling:

• Store in cool, dry environment (20-25°C ideal)

• Maintain charge level at 40-60% for long-term storage

• Keep away from water, moisture, and direct sunlight

• Use insulated tools when handling multiple batteries

Installation Notes:

• Ensure proper polarity when connecting to devices

• Use appropriate battery holders or cases

• For multi-battery configurations, use batteries of same type, age, and capacity

• Implement proper balancing for series/parallel configurations
