Excellent Trolling Motor Battery. Light Weight, Powerful and Hold a huge charge for all day use.

I needed a 100 AH lithium battery/charger combo like this so that I can run a portable refrigerator/freezer in my car. I like to give out food and cold drinks to homeless on street corners. (I bought the refrigerator/freezer here on Amazon also at an excellent price), This battery and charger function perfectly. It is very easy to use, weighs far less than lead acid, it fits nicely in the rear cargo area in an inexpensive plastic marine battery box that is securely mounted back there, and the output is a far better battery compatibility to run the 12 volt freezer/refrigerator. (The vehicle 12 volt power port shuts down at key off.) It has bluetooth to show State of Charge, but as a matter of fact, this battery and charger is so good, I've never had to know where the State of Charge is because I just plug it into the 120 volt outlet every other or third day or fourth day. (The refrigerator/freezer only uses 48 watts. That's 25 hours run time with this excellent battery). So this 1.2 kWh battery and matching charger is a great combination if you want lots of power independent of your vehicle.

Easy to use and charge. Holds charge for a long time. Went out on the lake 3 times with troll motor and still has charge left. Handle makes it easy to transport. Works great, even used it to charge cell and tablet during storm and power loss.

Arrived in good shape, looks well made, put it in my boat for a trolling motor so far I am satisfied with it. I am a fan of Lifepo4 batteries, bought a different brand 2 years ago for solar work shed and it hasn’t lost any power.

So far so good. Used it for my trolling motor for about 3 hours and I hardly used any charge. I’ve also been using it to do different things and so far so good. However, I’ve only had it for a short while. 6 months to a year usage will tell true value.

I purchased 2 of these batteries to run in series for my 24V Minkota PowerDrive electric motor. The batteries were slightly longer than my Interstate lead acid batteries so I had to change orientation by 90 degrees in my battery compartment. I also mounted the chargers that came with the batteries. I just went on a three day fishing trip. The battery life was exceptional! I couldn't be happier. I think I could run 2 or 3 days on a single charge. Hopefully these batteries hold up for several years as advertised.
