This cell requires strict voltage and temperature limits to prevent damage and ensure safety. Use only with a compatible BMS and avoid exceeding charge/discharge parameters.
- Voltage Limits: Maintain cell voltage between 2.0V and 3.65V to avoid over-discharge or over-charge.
- Temperature Ranges: Charge only between 0°C and 45°C; discharge between -20°C and 60°C.
- Charge Current Restriction: Maximum charge current of 12.5A is allowed only when SOC ≤40% and charging duration under 5 minutes.
- BMS Requirement: Always use a battery management system with overcurrent and short-circuit protection.
- Thermal Management: For high-rate discharge above 20C, ensure adequate thermal management to prevent overheating.
Follow these steps to safely prepare the cell for use and integrate into a system. Always adhere to the specified electrical and thermal limits.
Required Equipment: Battery management system (BMS) with overcurrent protection, Thermal management system (e.g., active cooling)
- Verify State of Charge
Verify the cell's state of charge is at or below 40% before applying the maximum charge current. - Connect BMS
Connect the cell to a BMS that provides overcurrent and short-circuit protection. - Set Charge Current
Set the charge current to 2.5A for standard charging or 5A for fast charging, and do not exceed 12.5A under the specified conditions. - Monitor Thermal Conditions
Ensure adequate thermal management, such as active cooling, when discharging above 20C.
What is the maximum continuous discharge current and pulse current capability of the 2500mAh 26650 LFP cell?
The 2500mAh 26650 LFP cell supports a maximum continuous discharge current of 50 A at 25°C (20C rate) and a long-pulse discharge current of 75 A for 60 seconds. These ratings are specified in the technical datasheet under discharge parameters, making the cell suitable for high-drain applications such as starter batteries and power tools.
Can this 26650 LFP cell be used in automotive starter battery and power tool applications?
Yes, the cell is explicitly designed for automotive starter batteries, high-power electric tools, UPS systems, drone power packs, and portable jump starters, as stated in the application scope. Its 20C continuous discharge and 75A pulse capability, combined with a 2000-cycle life at 80% DOD, make it suitable for these high-rate, high-reliability uses.
What are the critical safety features and charging constraints for the 26650 LFP cell?
The cell incorporates a built-in explosion-proof safety vent and passes nail penetration without fire or explosion, reflecting intrinsic LFP safety. Charging constraints include a maximum charge current of 12500 mA only when cell SOC ≤40% and charging duration <5 minutes; standard fast charge is 5000 mA. A BMS with overcurrent and short-circuit protection is required, and proper thermal management is advised for >20C discharge.
The 2500mAh 26650 LFP cell provides 50A continuous discharge and 2000-cycle life, but requires thermal management above 20C and restricted fast charge conditions (SOC≤40%, <5min) for maximum current.
Positive
- Ultra-High Discharge Capability: Supports 20C continuous discharge (50A) and 75A pulse for 60 seconds, suitable for starter batteries, power tools, and UPS systems.
- Extended Cycle Life and Intrinsic Safety: 2000 cycles at 80% DOD under 25°C with built-in explosion-proof vent and nail penetration without fire or explosion, ensuring reliable long-term operation.
Trade-offs
- Thermal Management Required for High-Rate: For discharge rates above 20C, proper thermal management must be ensured to prevent overheating and maintain performance.
- Restricted Fast Charge Conditions: Maximum charge current of 12500mA is only permissible when cell SOC is ≤40% and charging duration is under 5 minutes; standard fast charge is 5000mA.
