This is a brand-and-capacity planning profile, not a verified SKU specification. Confirm the exact model, current datasheet, permitted boat application and warranty with the supplier. Boat Battery has not independently bench-tested this battery. See how we test.
Suitable boat applications
Offshore catamarans on 24 V.
Compatibility limits to check
The boat is 12 V and staying that way.
For the brand as a whole — support network, documentation and where it falls short — read the Invicta review.
Before buying a 24V 100Ah Invicta battery
Ask for the exact model code and installation manual. Confirm the case fits through the compartment opening with clearance for terminals, cable bends and restraint. Check permitted mounting orientation and environmental limits; capacity alone does not establish suitability for a boat.
Match the battery’s continuous and surge discharge limits to your largest loads, then verify the combined charging current and the response to a BMS disconnect. For multiple packs, obtain the manufacturer’s series or parallel instructions before designing the bank.
