The owner of a 42-foot sailboat, Paragon, replaced an aging house bank of four 255-amp-hour AGM batteries with four 608-amp-hour Fogstar Drift LiFePO4 batteries, creating a 2,432-amp-hour system.0:27 The lithium-iron phosphate upgrade reduced total weight by 48 pounds per battery while significantly increasing usable capacity and charging efficiency.2:15 To manage the high potential current, the installation uses individual 300-amp Class T fuses and Blue Sea Systems on-off switches for each battery, connected to positive and negative bus bars rated for 1,000 amps.21:37 This parallel configuration prevents the need for excessively thick cabling while ensuring safety. The system integrates with the Fogstar Drift app via Bluetooth for real-time monitoring of voltage, cycle counts, and state of charge.4:24 The owner secured the batteries in the locker with custom wood shims and overhead beams to prevent movement in heavy seas.12:52 Proper planning and individual fusing are essential when paralleling high-capacity lithium batteries to handle potential discharge loads safely.
