24V 80Ah Lithium Battery

2480-BT

Do you have a 24V trolling motor or 24V solar system? If yes, then this battery is for you. With 2kWh of storage, it’s engineered to fit in a compact Group 31 case. This tank will take your power system to the next level. Built-in Bluetooth gives you peace of mind at your fingertips. And, low-temp charging protection is built in!

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 today’s fame.

Game Changer
This purchase has been a game changer! I went from two traditional lead acid trolling motor batteries to Millertech's 24v 80ah lithium and all I can say is convenience! I've fished 4 days in a row approximately 5 hours per day with wind and a strong tide coming off of a full moon and my battery shows 61% which is absurd longevity! Great customer service and amazing products!

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😊!
