Latest company case about Redefining Performance: The 7.4V High-Capacity Battery Pack Delivers Sustained Peak Power for Cordless Tools
The Industry Pain Point:

In professional construction and woodworking, craftsmen have long been constrained by the “performance fade” and “range anxiety” of cordless power tools. Traditional batteries suffer from rapid voltage sag under high loads (e.g., continuous drilling, driving screws into hardwoods), causing tools to lose power mid-task, impacting efficiency and precision. A battery that can deliver stable high voltage, enduring burst power, and rugged durability has become key for premium tool brands to create differentiated products.

Our High-Performance Match:
The 18650CA-2S-3J Li-ion Battery Pack is engineered as the power source for demanding applications.
  • Stable 7.4V High-Voltage Platform: Compared to single-cell batteries, the 7.4V nominal voltage provides the motor with higher starting torque and no-load speed, ensuring robust power output even when the battery is half-depleted—eliminating the frustrating “strong start, weak finish” experience.
  • 2250mAh Capacity with High-Rate Discharge: The 2S configuration optimally balances voltage and capacity. The selected power-grade 18650 cells support continuous high-rate discharge, effortlessly meeting the peak current demands of tools like angle grinders and impact drivers during startup or stall conditions, protecting the tool motor and extending its service life.
  • Industrial-Grade Protection & Construction: The pack features a flame-retardant reinforced casing and an internal shock-resistant design to withstand common jobsite drops and impacts. The smart BMS focuses not only on standard protections but also on over-temperature protection and load balancing, preventing safety risks in high-temperature summer environments or during prolonged continuous operation.
