Are the Victron litium smart batteries suitable for use in a marine environment? They are only IP22. This is for use on a small 12M sailboat. In no way is it a dry environment. Is the Victron Superpack a better option. We do not need 24-48v series.

If you are just after a simple 12 volt (low to medium current load) lightweight solution the Superpack is an ideal, cost effective, solution as the electronics (BMS) are built into the battery. The SuperPack also has a higher tolerance for water ingress (IP43) (a battery box would go a long way to upgrading that further). That said regardless of what you choose you may need to consider an additional DC-DC charger or regulated alternator to charge the battery as Lithium batteries and unregulated alternators do not always play well together. Hope that helps.
If you have been running lead acid batteries in that space, you will also successfully run a LiFePO4. I have a LiFePO4 battery form a different vendor, but with similar IP rating in my boat. No problems so far.
If you want to extra protect the battery, there are cases made of fibreglass that can be even waterproof.
