BatteryRuntime: Hours Tool

BatteryRuntime is an accurate, intuitive battery runtime calculator designed to estimate operational run hours based on battery capacity, voltage, chemistry, and electrical load.

Key Features:
• Accurate Runtime Hours: Estimate operational runtime and real-time cutoff finish clock based on battery capacity (Ah) and voltage (V).
• Battery Chemistry & DoD: Built-in recommended depth of discharge presets for LiFePO4 (90%), Li-ion NMC (80%), and Lead-Acid / AGM (50%), plus custom adjustment.
• Inverter & Output Efficiency: Model DC direct power (100%) or AC inverter conversion loss (85%) for true battery-side discharge loads.
• Quick Start Presets: 1-tap setup for RV LiFePO4, Car AGM, Power Bank, Portable Power Station, and Home ESS.
• Interactive Appliance Reference: Quick-fill load power for common devices (car fridge, phone charger, projector, electric kettle, microwave, and more).
• Essential Battery Metrics: Instantly view usable energy (Wh), total capacity (Wh), discharge current (Amps), and C-Rate.
• Visual Battery Indicator: Dynamic battery state graphic with color-coded remaining charge feedback.
• Scenario Management: Save, rename, update, and compare multiple setups for off-grid, camping, marine, and solar battery systems.
