Boat Owner

I purchased the (2) RELiON 100AH as well as the cranking battery. These are used in my boat for fishing/boating applications and they have been very impressive thus far. I have always believed in running the lightest rig possible. I take my fishing excursions very seriously and want to maximize my time on the water when allowed and know that I have put every effort forth in making it an enjoyable experience.

My boat has a better draft, quicker hole-shot, and actually handles different now that I have removed all the weight from traditional LA batteries. I have noticed increased power in my trolling motor and have much more run-time. The charging is simplistic, and it has changed the pattern in which I charge my batteries. Unless tournament fishing, I am simply a relaxed weekend warrior. Although I have put them to the test of fishing 3 straight days of hard run-time, and they still had 50% power remaining.
