Which is better for a 12V camper or van?

The Victron Cyrix-ct. It runs on 12V or 24V, while the Blue Sea 7610 is a 24V-only relay. The Victron is also far cheaper at $46.83 at RV Parts Giant as of November 3, 2026.

Which is better for a gasoline boat?

The Blue Sea 7610. It is ignition protected and IP67 sealed, which the Victron's IP54 rating does not match. That safety rating matters in an engine compartment with gasoline vapors.

Is the Blue Sea 7610 worth the extra money?

Only if you need 24V operation, ignition protection or IP67 sealing. Otherwise the Victron does the same combining job for $46.83 versus $123.81 as of November 3, 2026.

Which handles more current?

The Blue Sea 7610 is rated 210 A intermittent for 5 minutes. The Victron 120 A model is 120 A continuous and 180 A for 5 seconds. Victron also sells a 230 A version if you need more.

Will either work with a smart alternator?

The Victron closes only when voltage reaches 13.0 to 13.8 V, so a smart alternator that runs lower may never trigger it. Check your charging voltage before buying either relay.

Do either of these charge a lithium house bank?

Neither is a lithium charger. The Victron is aimed at lead-acid house batteries. For lithium, check the battery maker's relay and voltage requirements first.
