The difference between the right batteries.

What happens here

This project compares the performance of two popular Harbor Freight impact drivers, the Hercules and the Bauer, when driving 5-inch lag bolts into a wood block. The primary focus is to demonstrate how different battery ampere-hour (Ah) ratings (1.5 Ah, 2 Ah, and 8 Ah) impact the speed and efficiency of these tools, highlighting the significant performance boost provided by higher-capacity batteries.
