Location: Indiana | I found some calculations online that give an estimate of runtime for trolling motors at a given setting. This is probably not a hard fast calculation, but a reasonable estimate.
For Example: A 55 pound 12V trolling motor is likely to draw 1.2 amps per hour at 100%. Say you have a battery with 100 amp hour rating you might expect to get:
7.5 hours at 20% power
3.8 hours at 40% power
2.5 hours at 60% power
1.9 hours at 80% power
1.5 hours at 100% power
I found it interesting and probably just a good guesstimate. |
