Same. People used low quality Ni-Mh batteries and got what they paid for. Eneloops have worked great for me. Believe it or not, Duracell has been great too. It’s the energizers that have all been awful for me.

It’s be way harder for me to go back to corded tools. Li-Po tools are incredibly convenient. I’ve been able to buy adapters for dewalt batteries that make them work with all kinds of tools and devices (including an adapter for a Dyson handheld vacuum).
Lightweight, powerful, and the batteries can be swapped (as well as a decent amount of aftermarket batteries and adapters).
