What this video covers
The build of the aluminum catamaran *Delos 2.0* incorporates a 48-volt solid-state lithium battery system from the Australian company Safiri.▶ 1:48 Each 20-kilogram battery module provides 2.8 kilowatt-hours of capacity, and the system allows for up to 40 units in parallel.▶ 8:38 These batteries feature internal active cell balancing, a battery management system (BMS) with an 80-millisecond response time for short-circuit protection, and a 10,000-cycle lifespan at 80% depth of discharge.▶ 7:46 Compared to traditional 12-volt lithium setups, this configuration saves approximately 214 kilograms for a 50-kilowatt-hour total capacity.▶ 8:58 The electrical architecture utilizes digital switching via NEMA 2000-compatible modules, which decentralizes power distribution to reduce cabling complexity.▶ 14:38 These modules support Bluetooth-enabled wireless switches and integration with smart-home protocols for voice-controlled lighting and system monitoring.▶ 15:32 To ensure redundancy, the design includes manual bypass switches for critical loads.▶ 18:04 Former crew member Connor, a marine electrical specialist, joined the project to assist with the installation of these systems and the final lighting layout.▶ 11:48
