NOTE: Parkside X20V batteries do NOT contain over-discharge protection (it's located inside the tools), so beware what you use it for!

This is a mixture of two other adapters. The benefit is that this one locks to the battery, only needs one screw, standard terminals and optionally a bit of hot-glue.

I actually skipped the hot-glue as my wires were thick enough that the terminals were not moving much.

Additional items needed:
2 pcs male spade crimp terminals
1 M3 10 mm screw
