This post introduce a customer’s requirement of 14.4V Custom Lithium Battery Pack and our solution details.
Customer Introduction
This UK customer company sell portable devices used in cars, and is looking for a 14.4V 7Ah battery used in cars.
Customer Battery Requirements
14.4V Custom Lithium Battery Pack Solution Details
14.4V usually made of 4 series of 3.6V cells; power consumption: <20W means the rated discharge current<1.388A(1.388A=20W/14.4V) ; daily working environments means the working temperature range is usually between -20 ~ 60℃; battery size seems can use 18650 cell type as primary choice; LG brand is a better option than Samsung in this case becuase the rated discharge current is low and LG brand cell has higher performance cost ratio.
Cell type: LG 18650 3500mAh cell
Use LG 3500mAh 18650 cell, designed for high-performance portable car devices , the 14.4V 7Ah lithium-ion battery pack powered by premium LG cells delivers reliable energy storage and exceptional durability. With a nominal voltage of 14.4 volts and a capacity of 7 ampere-hours (Ah).
Cell Specification
At its core, the battery utilizes LG Chem’s cutting-edge lithium-ion cells, renowned for their stable discharge characteristics and long cycle life. The 7Ah capacity ensures extended operational time between charges, while the 14.4V configuration supports moderate to high-power devices without compromising efficiency.
The cells are engineered to maintain consistent performance across a wide temperature range (-20°C to 60°C), ensuring reliability in daily environments.
BMS Features
Equipped with an integrated 2A Battery Management System (BMS), this pack prioritizes safety and longevity. The BMS safeguards against overcharging, over-discharging, short circuits, and thermal runaway, while balancing individual cell voltages to maximize lifespan. Users can expect up to 500+ charge cycles with minimal capacity degradation, retaining over 80% of its original capacity even after heavy use.
