What this video covers
The crew of SV Delos prepares for a long passage by performing a comprehensive rig inspection and upgrading the vessel's electrical system. The host climbs the main mast to check fittings, swages, and pins for cracks, corrosion, or missing hardware, noting that the rig was last replaced in Thailand nine years ago. To resolve long-term battery capacity issues caused by cell imbalance in a 24-volt series configuration, the crew installs eight new Battle Born smart lithium iron phosphate batteries. The installation includes a Bluetooth-enabled hub that allows individual monitoring of each battery's voltage, temperature, and state of charge. Before finalizing the series connections, the host balances the batteries by charging each unit individually to full capacity. The crew also completes a 60-day provisioning run and addresses minor maintenance tasks, including clearing a blocked drain in the rain catchment system. After casting off from the dock, the vessel moves to a nearby anchorage to begin the passage. Balancing batteries individually before connecting them in series prevents cell degradation and ensures a healthier, longer-lasting electrical bank.
