- Installing a NEMA 6-20P plug on the end of the charger cord to match my 240V extension cord I had previously built
- Building custom 12-gauge interconnects with a crimper and round lug ends
- Hanging the charger in the preferred vertical orientation
- Wiring it all up and plugging it in.
And here is the completed contraption. The 1/4 inch plywood at the left is ready to be placed on top of the batteries to prevent things from falling onto the terminals and shorting them out (look at all those paint cans just waiting to fall :-)
