Ladies and gentlemen. I present to you the triple B

The bosch battery bodge
After having to abandon the odd ride and once riding 6 miles without power, I started looking on the bay of thieves for a 500w power tube battery pack as an extender for my 625.
Now as I have a gen 2 bike and 3 batteries I started fiddling.
After a fair bit of sawdust my plan worked out brilliant
The electric connecter bracket was removed and replaced with a piece of wood and some dence foam to the same height.
This allows the 625 to fit as normal.
Next is a second piece of wood and dence foam that just sits on top for the 500 to fit.
The 500 fits 90% into the downtube and a large Velcro strap keeps everything happy.
The neoprene cover is something I use a lot normally anyway.
So depending on the ride I have a load of battery options to choose from

@Zimmerframe I would have tried a solution to attach the plug directly to the battery, without an option for an easy swap of the battery - but interesting reading, thanks !

I seemed to struggle finding a wiring loom to do what I wanted without making something up that didn't screw up the electronics. And this way just works easily.
Next task is to sort out a way to hold a 500 within the triangle as there is room.
