What this video covers
The installation of three 100-amp-hour Unowix LiFePO4 batteries creates a 300-amp-hour, 12-volt house bank to replace an aging battery system.3:08 The project involves securing the batteries against a bulkhead with wood bracing and straps, and wiring them to a 3000-watt Renogy inverter-charger.3:08 Because LiFePO4 batteries maintain a flat voltage curve, the installation includes a shunt-based amp meter to accurately track state-of-charge, preventing the sudden voltage drops experienced with the previous setup.16:43 The installer uses 4/0 cable for the main runs, noting that while a T-class fuse is standard for lithium, a high-AIC-rated 250-amp breaker serves as the primary protection.1:51 To ensure clean connections, the installer uses professional wire-cutting tools rather than a hacksaw to prevent lug-fitting issues.5:44 After a capacity test drawing 150 amps, the batteries demonstrate their full 300-amp-hour rating.17:52
The test confirms the Unowix batteries deliver their rated capacity, though long-term lifespan remains to be determined.19:30
