Trolling Motor Run Time at Every Capacity and Draw

Real run time with the Peukert effect and the depth of discharge guideline both applied, in flooded, AGM, gel and LiFePO4.

Every page below is computed rather than written, from the same formulas the matching calculator uses, so a figure on a chart page and the same figure in the calculator cannot disagree. Each one carries its working, the basis of every number it prints, and gear chosen by those numbers rather than from a general list.

Researched, not professional advice. Every figure on these pages is labelled as a published engineering or manufacturer figure, a rule of thumb, or something that only exists on your own boat. Where a published figure does not exist we say so rather than estimating one. The capacity plate on your boat, the manual for your own equipment and ABYC E-11 for anything electrical are what govern.
