We take a deep dive into the Bosch GSR10.8VLI cordless rechargeable screwdriver. We begin by tearing down the original 1Ah lithium battery and upgrading it to a 2.1Ah using repurposed 18650 cells from a Panasonic 18V 4.2Ah. We then show you step-by-step how to reassemble the battery for higher output and longer run time. This is a great way to improve the performance of your cordless screwdriver and get more out of your tool. So if you're looking to upgrade your battery, be sure to check out this video
