How can boat operators calculate the total cost of ownership (TCO) when switching to lightweight lithium batteries?
To calculate TCO for marine lithium batteries:Log Loads and Duty Cycles: Measure currents/durations for trolling motors, hotel loads, and charging windows using shunts or battery monitors.Model Usable Energy Needs: Convert logged data into kWh requirements. For example, a 12V 200Ah LFP pack provides ~2.2 kWh at 90% DoD.Compare Lifecycle Costs: Factor in upfront costs ($900/kWh...
