The Challenge:
A construction team used a professional hammer drill equipped with this battery pack for concrete drilling during high-rise office building renovation. The tool drives a Φ16mm drill bit for continuous drilling (15 seconds per hole).

The Solution:
The 32LI-18650-CP-4S8P battery has become the ideal power supply solution. The battery’s 4S8P configuration delivers 25A stable discharge, and the 26.8Ah large capacity supports 8 hours of continuous daily operation (over 1,200 holes drilled), eliminating the need for mid-shift charging.

The heat dissipation design of 18650 cells prevents overheating shutdown under high load, and the BMS protection system avoids voltage drop, ensuring drilling precision (error ≤0.5mm) for scenarios like ceiling keel installation and pipeline embedding.

Technical Specifications:

• Model: 32LI-18650-CP-4S8P

• Chemistry: Lithium-Ion

• Nominal Voltage: 14.4V

• Rated Capacity: 26.8Ah
