Trolling motor batteries

**airshot** · 09-18-2025, 09:01 PM

I have the 140 ah TimeUSB battery for my 12v min kits 55# thrust trolling motor. I had over 20 hours of use with my trolling motor this past session before I recharged the battery. The BMS told me I had another 4 plus hours of use at that same avg amp draw....estimated 24 hours of continuous use. The battery was at 37% when I hooked up the charger, 6 hours later the battery was fully charged.

Maybe my old 80# Terrova needs service but I definitely gave it a work-out yesterday. I only have a 16' aluminum boat, but it was 2.5mph into the white caps, pulling 6 lines. I did have the Yamaha providing a little forward motion, but the Minn Kota had to go to full power most of that 6 hours just to maintain the direction.
On calmer days, it will only require about half power and will last 16 hours plus. And since mine is a 24v system, my two 100 ah batteries in series only give me 100 ah, compared to your 140. Are you trolling with your Minn Kota? How big is your boat?

I also have a 16' aluminum but probably not as big as yours. I mostly use the spot lock, but early in the season use it to troll for walleye. I also have a little kicker, a 2.2 hp Merc just for forward thrust when it gets windy. This year, the little kicker was not needed, the MK averaged around 4-6 on the speed control ( 1-10) and was part of the 20 hrs time on my battery. Your 24v uses half the amps my 12v volt motor uses. These Lipo batteries are quite impressive at least in my eyes.
