Works well for my setup
Millertech is my first experience with lithium batteries on my 18 ft Xpress aluminum boat. I bought 2 of these 55 amp hr batteries and run them in series to a 24 volt trolling motor. My first two days on the water were 9-hour bass fishing days, both had steady wind and were not brutal, but above average trolling days for me. Started both days fully charged. .. drained batteries down to 80% on one day and 79% on the other. I had been concerned that maybe I needed 100 amp hr batts to survive a full day with wind, but now I think the 55s are just right for how I fish. The app is handy too. So far I am a Millertech fan - thanks.

New to Millertech
Batteries and charger work great. Love the bluetooth and App to let me know level of charge.

Great Service, Great Batteries!
Batteries came very quick and packaged very well. Hooked them up, and went out to try them out. I have a 17ft tracker, and after about two to three hours of running around with my 24V trolling motor, I still had 95% capacity on my batteries. Being able to see the capacity and what the batteries are doing in real time on the App, is great. Thanks MillerTech!

55ah battery
I bought a Millertech 55ah to run my electronics. My first impression is the Bluetooth data that the battery shows. I read a lot of reviews on many companies batterie's, but I came back to these principals. American made and here in Ohio. The company techs have great knowledge on the products they sell.
