I didn't want to rate the battery until I got a chance to use it 1st. Since I am using it in 2 different boats My 1st was a quick trip in my canoe. I noticed to canoe seemed to increase the speed; I can't verify since I didn't have a GPS to get the true speed. Battery life 3hrs at full use I was at 66%. I like the monitor of the battery functions on my cell phone. My true test will be when I get to use it on my larger boat. I love the weight of the battery 24 lbs vs 60+ lbs for my old battery. My only complaint would be the connection. I would prefer a bolt and wing nut or nut for a connection this would be much easier for multi function use, my boat uses a nut and bolt connection my canoe clips.
