48V battery double throw switch options

[solar12345]

Dual battery back up system. 48VDC batteries (two different lithium banks) with hybrid inverter, existing DC solar. I'm looking for a double throw switch (on off on) that's rated to 48V and at least 200a to switch between battery banks. Trying not to break the bank.. Marine battery switches don't seem to be rated to 48VDC. Any suggestions? Thank you!

It means not costing a lot of money.

Cost more 240V DC to 48VDC

Fully charged 48v lithium battery banks are usually at 56-57v in my experience. I'd feel better using a switch rated for 240v DC than one rated for 48v.

48v dc nominal in quality brand change over switch, 60v, more, maximum continuous voltage
