Old 12V Impact Driver Restoration & Upgrade (NiMH to Li-ion)

In this video I show you how to restore an old e-robur impact driver. The impact driver used worn out Ni-MH batteries and I upgraded it to Li-ion.
In this project, I used many tools to check and build lithium batteries. Here are the most important of these tools.
Tester batteries lithium Liitokala Lii-500 : s.click.aliexpress.com/e/_Dkf...
