Does someone have the physical dimensions of the lim enclosure?

Yah, you're probably right that will prove to be the best solution.
I was hoping against hope for something even smaller, since that charger is what the motorcyle came with from the factory in a big waterproof pelican/brief case.

Edit:
Oh shoot, missed the part about that Volvo charger. Thank you!

Could anyone provide advice finding a charger from an OEM that could be found fairly easily?

Very low power would be fine, I'm just hoping for the smallest form factor possible, since this would hopefully be for a motorcycle.

350V max pack voltage.
