DeWalt 20V to Hercules 20V Battery Adapter (with BMS)

Works perfectly for me...Going to order another!

The DeWalt 20V to Hercules 20V Battery Adapter works as advertised. I use it on my Hercules Reciprocating Saw to prune bushes and tree limbs in my empty lot.

Works great. It fits a bit tight the first time. I was concerned about damage, but a good push fixed it!
