Protective case for Bosch 500 watt battery

[ACAG]

Can anyone suggest a protective case to transport my Bosch 500 Watt battery when it is not on my Ebike?

Thanks

I carry mine in a nice red metal toolbox .
I keep two batteries wrapped in soft fiberglass matting in side when traveling. Actually I need another one as I now have 4 batteries.

You can use an extra large neoprene wine tote.
