Voltage and Capacity Matching: 7.4V is the standard voltage for dual-series 18650 batteries, and the 2000mAh capacity balances battery life and device size, avoiding excessive space occupation.
High-Rate Discharge Performance: 5C rate means a maximum discharge current of up to 10A (2000mAh x 5), enabling rapid power delivery to meet instantaneous high load demands.
Structure and Safety: 18650 cells are highly mature, and standardized production ensures good battery pack consistency. With a protection board, overcharge, over-discharge, and overcurrent protection are provided.
Portability and Durability: The 18650 form factor is compact, resulting in a lightweight battery pack.
Cycle life typically exceeds 500 cycles, leading to lower long-term operating costs.
Applications:
Small Power Tools: Handheld drills, mini grinders, etc., requiring instantaneous high-power motor drive; the 5C rate ensures sufficient power for tool startup and operation.
Consumer electronics: High-end toy cars, drones, model airplanes, etc., requiring 7.4V voltage to meet motor needs, with a 2000mAh capacity balancing battery life and lightweight design.
Emergency and backup power supplies: Small UPS systems, emergency lighting equipment, high-rate discharge for rapid response to power demands, standardized battery cells for easy maintenance and replacement.
Medical and testing equipment: Portable monitors, small analyzers, etc., requiring stable voltage output and reliable discharge performance to ensure accurate equipment operation.
