The 24V 80AH will power your trolling motor under heavy use for a minimum of 6+ hours. 2 of these 2V 80AH connected in parallel will power your motor for 12+ hours. We have reports of anglers using 1x 24V 80AH for multiple days without killing it. Although that is very likely true, at Millertech we believe in giving you real world numbers that do not lie. We would much rather under promise than over promise! We believe the long term results are much more important than todays fame.

24 volt trolling battery
I have only been two trips dragging baits for catfish since installing the 24 volt MillerTech lithium battery. Working against the wind and current and maintaining a .5 mph, the battery used only 10%. This was a full day of dragging baits. I was honestly surprised and impressed. It charges quickly and saves around 80 pounds weight compared to the lead acid batteries I replaced. I have not been disappointed in my new battery or the great service received from MillerTech.

1st outing with new battery
One outing so far. We fished in steady 15 plus mph winds for 3.5 hours on spot lock most of the time and used only 20% of the battery power. Worked well and charged right back up to 100%. Also caught 102 fish😊!

Millertech's batteries are great. I use it all day and still have plenty of battery left at the end of the day. I love the blue tooth feature that let me know the percentage charge left on my battery. I recommend them to my friends.

Awesome battery
Awesome battery, first use was bass fishing for 7 hour hours. Check the battery level after fishing, and it had 85% capacity left. My AGM’s were dead after 5 hours. Awesome battery!!!!!!!
