Description
Power Pack LiFePO₄ 1S 3V 18000mAh 1S3P 3C with BMS LFP Battery Pack
The Power Pack LiFePO₄ 1S 18000mAh 3C Battery Pack with BMS is a rechargeable lithium iron phosphate (LFP) battery designed for compatible low-voltage electronic devices, portable equipment, and custom power applications.
Featuring a 1S3P configuration, this battery pack uses three cells connected in parallel, assuming 6000mAh cells. It provides a capacity of 18000mAh (18Ah) at a nominal voltage of 3.2V, delivering approximately 57.6Wh of energy.
The integrated Battery Management System (BMS) helps manage and protect the battery. Depending on the selected BMS model, protection functions may include overcharge, over-discharge, overcurrent, and short-circuit protection.
With a specified 3C discharge rate, the theoretical discharge current is 54A. Actual continuous discharge capability depends on the cell specifications, BMS rating, wiring, connectors, and thermal conditions.
Note: A single-cell LiFePO₄ battery has a nominal voltage of approximately 3.2V, rather than exactly 3.0V. Confirm that your equipment supports the battery’s operating voltage.
