@diy_with_stack: How long can a 220Ah tubular battery last compared to a 100Ah lithium battery? In this video, I explain Depth of Discharge (DOD), usable battery capacity, and how they affect your inverter backup time. Don’t choose a battery based on Ah alone! #BatteryBackupTime #LithiumBattery #TubularBattery #DOD #InverterBattery
