As I said somewhere above, I would provide dimensions, etc for the new box for the PC680 battery.
Built from mostly 3/4x3/4x.125 angle, .0625x3/4 cold roll and a piece of 1/8x1.5 flat stock. I also used a 6" Stanley hinge and a couple of pieces of 1/8 neoprene for vibration resistance, tho not as yet glued in place. The front 'latch' (hinge) has a piece of oak as well for a spacer - this still needs a wee bit of work, but is about as it will be when finished. I also tacked three nuts to attach the cover, which is yet to be made
I'll extend the bottom with another piece of steel for my latching solenoid mount which will be used to disconnect the battery. I'll eventually add that photo too.
Fun project. Total build time 2-3 hours with a couple cuppas.
And they will probably not be in the correct order

I saw last night on fb about John. The world sure lost a great one. I'm going to miss his humor, advice, and perspective from another portion of the world. Rest in Peace Johnboy.
