    No complaints here. Affordable battery that works as promised and i use it on a daily basis for my work van. I brought mine for almost years now. Its best if you also equip your vehicle with a dual battery isolator for optimum performance. I run all types of power tools and it consistently maintains a full charge. I like it so much i brought another battery for my second working van.

    It’s just what you’d expect… shipped in a very sturdy set of boxes. My only complaint is that the labels are only on the side of the battery so you can’t read them when it’s installed and only the top is visible. No markings on the top whatsoever except to mark the pole polarity.

    I’m not techy with batteries so I can’t speak with intelligence about it but it runs the led lights, max air fan, electric cooler, tv, and charges my devices in my van.I charge it using one 100 watt solar panel.I even ran my air conditioner for a while (maybe 15 minutes) off my 6000 watt inverter just to see what it would do.I’m probably going to try to see how long it will run it sometme.UPDATE:I ran a window unit, an electric cooler, a small tv, charged my phone and used led lights for 3 1/2 hours on this one battery on a sunny day!Wow!My little 100watt solar panel was helping I’m sure but mostly it had to be the battery.

    This thing weighs in at a mere 120 lbs. Make sure you lift with a twisting, jerking motion. Take your back completely out of the equation. FedEx delivered in a well packaged box. They did leave it upside down though….guess those labels on it don’t really mean anything….. Good thing it is a sealed battery! I’m sure it will work just fine for my applicatio, although I havent hooked it up to the system yet.

    So far so great! Used this to upgrade our power situation on our A-frame camper, and it has given us vastly more power capacity. This in combination with solar has let us go very long periods of time with adequate power, and I’ve never had to resort to a generator since purchasing it! It’s been two months, and we’ll see how it goes long term.

    Packaging copy be better, the handles are not very assuring meaning they feel like they will break! I have the fact that the terminal post are screw in type. Would much rather prefer the standard type of post like on a traditional battery. Other than that is exactly what is advertised

    These batteries are awesome – and I got phenomenal customer support as well. I have about 8 of these for two off the grid RV spots… they power a few large RV’s and I’ve used them to brew some off my beer off the grid… overall, the batteries last forever even when I am messing with my system and take them off line.. later on they still have a full charge and can power most anything I can throw at them. they are heavy – but I’ll buy more.

    for the price you cant beat them. I do question the 200 amp hour rating (think they are a little on the weak side).

    Great battery, I have been using it for one year in my camper and it works great. Great company to work with, my battery started leaking after about 3 months from what appeared to be damage from shipping, after contacting the company and sending in few pictures, I was shipped new battery and received it within few days. Highly recommended.

    So far so good. Just watch out. Casing seems thin. Some cracks. A little fragile. I think cause it is so long.

    Purchased 1 to check ability under solar power, great, then purchased 5 more and will buy another 5 to add to my solar grid. Operating a 1000 watt well pump and 1200 watt coffee pot with no problem, virtually illuminating generator.

    Arrived in good shape, all black and shinny like a mirror in only a few days all the way across the U.S.. Fully charged. Just now getting it installed. I have 500 watts of solar and am hoping they will keep them charged.

    Too early in service life to make comment on real performance but is a big improvement over the dying batteries they replaced. They are big and heavy (expected for lead acid battery chemistry) but I have a crane. They were the best value I could find for capacity and price.

    This is the second one I added to my setup. I liked the first one so much that I bought this one to hook up in parallel for a total of 400AH.

    Using for a house battery in our Sprinter. So far so good, but haven’t added some of the bigger components like a fan or heater yet. I’ll update when that happens. Seems to hold a charge for a while, but its only powering lights and a cooler at the moment.

    I was nervous buying this thing with so little documentation and specs. I have treated it with best practices like any AGM battery and it is providing good life so far and seems well built.

    Installed in my RV. Used it exclusively for three nights with a TV running off of an inverter all night for one of them. Still had plenty of juice to run the slide out in at the end of the weekend.Thinking of purchasing a second battery along with a 100 watt solar panel to easily stay off the grid for more than a week without having to get a generator.

    Got 2. Ordered 2 more.1 month later: Got the second set 2 days before hurricane Irma came to visit. My wife and I were comfortable knowing that these 4 monster batteries would keep us powered through the storm. And that’s exactly what happened. Although these batteries are strong and stable, they’re not an unlimited source of power. No battery is. Expecting a couple days of minimal sun, we practiced basic energy conservation. No hair dryer or microwave oven use. We were still comfortable and we felt safe. I intend to add 4 more of these this month. When I get licensed and start my solar power business, I will install Mighty Max Batteries.

    Had this battery for a month now. I have it hooked up to a 400 watt wind turbine with a controller for charging and a 3000 watt inverter. At first it would charge completely, but now it seems like it won’t take a full charge after we used it for a long time one day. Now it seems to drain quickly. I know cold temps can affect the life..so now that its warming up I’ll know more. It did work pretty good at first during the winter months, so I’m a little concerned.working hard and well for the last 8 months….adding another to my system with a solar panel for when my wind dies off for a few days. I can get a max charge of about 12.8V with my turbine, 13.3V with a 10A charger. Once I put a really good charge back on it with the 10A charger it charges up to the same point (12.8V)now……Feeling confident!!

    Except for the weight of this battery, which is very heavy (not atypical of batteries); the battery performs well. On arrival, one of the handles was broken, and the seller took care of me very quickly. They will make it right. Awesome company, awesome batteries.

    Excellent batteries at an excellent price ( each was literally half the price of the same product at West Marine) and they were delivered free! Recommend highly!
