Lead Acid

How long will it last; 12V, 100Ah Lead Acid Battery powering a 600W Motor max 55A draw (DC)?

12V, 100Ah Lead Acid Battery powering a 600W Motor max 55A draw (DC)?

This is to calculate a trolling motor for a light weight boat. Appreciate it depends on how heavy the boat is but an approximate would be appreciated!

Thank you

in the same way you never run a battery to zero charge, you never run a motor at max amps for too long.

assume a nominal curent draw of 20A over the duration of the draw, and a battery rundown to 50% -- 50Ah consumption. Under those conditions, you'd be able to run the motor for about (5/2) = 2.5 hours.
