I have four of these in my 17ft aluminum Ranger bass boat. Two are wired in parallel for a 12v trolling motor, one is up front under the deck for a Garmin Live scope black box and a Garmin 126sv and one for cranking/accessories. They all perform flawlessly and outlast me on the water. The three in back are on a Noco Genius 10X3 charger and the one under deck has its own Noco 10X1 charger. Although it's not recommended, the battery used for cranking does just fine in starting my Mercury 75 four stroke. They are group 31 size but weigh 26-27lb, saves a ton of weight even over group 24 sized batteries. Timeusb is an excellent seller with great communication. Definitely recommend these batteries.

I have use it twice now. Came in a nice foam box, well protected. 3.125V out of the box. I'm using it for my bow graphs HDS12s, AGM wasn't cutting it. I read the battery out after, said it have 75% and 69% left on the power. So, it doing good. Hope it last a long time. I would purchase them again.

I like these batteries. They seem to work well in the 5th Wheel. Just know that it is a little nerve racking if you get it to replace a bad deep cycle battery just before you have to head out and realize it is not fully charged. It worked but I had a cramp in my crossed fingers.

I love this battery. The overall look and sturdy feel to this battery is just great. It is a lot bigger than what i was expecting but its size screams "I mean business, don't worry, i got you(when/if you lose power)". I ended up buying 2 for my debut into the DIY solar game. I use them to power one of our outdoor pond pumps in the never ending battle against the power company. But if i had the money i would probably buy 2-3(probably 10) more and try to hook up some of our indoor appliances since the performance, look, and quality of these is nothing short of awesome/amazing to me. And i am not a solar expert by any means but they charge fast, output enough, and last a good amount of time at decent load(75-100w continuously). Now i know that is probably not really high in the bigger solar game picture. But its enough to power more luxuries than i would need or use if the power went out like it often does for no reason or i just missed the "planned outage" memo. Also, its way quieter than my inverter generator, doesn't spit out toxic fumes, and i have not felt it get hot to the touch at all which i assumed it would at some point. And i love the look of this battery, it sounds weird i know, but if you buy one you will understand what i mean. I am just glad to know that i have at least 2 of these watching my back in case......well just in case of anything.
