12.8V 2.2Ah LiFePO4 Battery 3000 Cycles 70C Pulse 154A for Small Devices

12.8V 2.2Ah LiFePO4 Battery 3000 Cycles 70C Pulse 154A for Small Devices

Small But Powerful LiFePO4 Battery
This 12.8V 2.2Ah lithium iron phosphate battery delivers reliable power for portable devices, backup systems, and small electronics. With a 70C pulse discharge capability (154 amps for less than 1 second), it can handle high surge loads despite its compact size. The integrated BMS provides complete protection against overcharge, over discharge, overcurrent, short circuit, and temperature extremes. Weighing only 0.5kg and measuring 112 by 69 by 88mm, it is easy to integrate into space constrained applications.

Core Specifications
Nominal voltage is 12.8V with 2.2Ah rated capacity. Dimensions are 112mm length, 69mm width, and 88mm height. Weight is 0.5 kilograms. Terminal type is N1. Cycle life exceeds 3000 cycles at 80 percent depth of discharge while retaining over 80 percent of original capacity. The battery uses LiFePO4 chemistry, the safest lithium technology.

Discharge Performance
Continuous discharge current is 2.2 amps. Pulse discharge current reaches 154 amps (70C) for less than 1 second, making this small battery capable of starting small motors or handling communication burst loads. BMS discharge cut off voltage is 8.8V with reconnect at 10.8V. Recommended voltage disconnect is 10V. Short circuit protection activates within 300 to 800 microseconds.

Charge Parameters
Charging uses the CC CV method with charge voltage of 14.4V (fixed range). Recommended float voltage is 13.4V. Recommended charge current is 2.2 amps for standard charging (1C). Maximum charge current is 8.8 amps for faster charging (4C). BMS charge cut off voltage is set to 14.4V.

Temperature Range
Discharge temperature range is -20°C to 60°C. Charge temperature range is 0°C to 45°C. Storage temperature range is -20°C to 45°C. BMS high temperature cut off is set to 78°C, providing an extra safety margin.

Applications
This 12.8V 2.2Ah battery is ideal for portable medical devices, handheld instruments, wireless sensors, backup power for alarms and security systems, small robots, RC vehicles, LED lighting, and communication equipment. It is also suitable for powering IoT edge devices and portable test equipment.
