power queen12V200Ah PLUS Low-Temp Cut-off LiFePO4 Battery, Built-in 200A BMS, Max.2560W Load Power, Rechargeable Deep Cycle Battery for Trolling Motor, RV Camping, Off-grid Application

Just installed and is coupled to my Go Power 3000 Watt Inverter in my small Travel Trailer. I had previously had a Stark Power 12V100AH battery that was installed in 2016 (Still going strong) and wanted to upgrade to a larger size along with getting the battery for $430 with the discounts (I bought the Stark Power one for $1100 back in 2016) this was a no brainer for me. Install was a breeze as I had sized everything in 2016 to accomodate a larger battery bank when costs came down. The Charge was at 13.2 VDC out of the box ~70% if I recall what their booklet showed. First thing I did was fire up the AC to see if it would run and it did with ease, I have a 13.5K BTU Dometic without soft start and the Powerqueen/Go power combo fired it up quickly, barely even noticed that first crank of the compressor it was so quick. I shut the AC off and then popped a batch of popcorn (1440W old school presto poplite air popper), worked like a champ, aside from the cheaper prices, the popcorn machine was the main reason for the upgrade ;), nothing like a fresh batch of popcorn popped in the middle of nowhere without having to fire a generator up. I have this battery coupled with 300 watts of solar on a MS Prostar MPPT-25 charger, I expect this battery to be well above my needs and to have enough buffer that I'm not worried about having a generator on hand to charge it. I am not planning to run the AC on the battery as I figure it would only run 1.5 hours to 2 hours at most and the battery would be exhausted. If the performance and life is anything like I have experienced with the Stark Power 12V100AH LIPO4, then I will be literally a Happy Camper. Will update down the road.

WOW, its like having a nuclear power plant for your shed:) OK, not quite, but wow it lasts way longer than my old lead acid battery. I have a solar pannel keeping it topped off and was able to use a 2000w inverter to run a chop saw and a vacuum for hours. I also tested it using an electric leaf mulcher for over 2 hrs, no problem.

I liked the low temperature protection which for some crazy reason is ignored or overcharged for in LifePo4 100AH batteries. It’s a 1$ sensor plugged into the BMS ! Yet manufacturers charge 50-100$ more usually! Please keep the cost down. Better yet make it standard. Thanks Power Queen!

As with all power Queen products it is exceptional. I have several of these and I'll be ordering several more and the fact that one I'm quite particular and two I'm a return customer says a lot for me. The high temperature cut off and the low temperature cut off for a big plus. They overcharged protection and the low voltage shut off for dead on with the specifications.

I made the best choice on picking this lithium battery. Had multiple units running off of it had no problems.

Update: After ordering the initial battery to build a battery box to hold a full battery bank. The battery became unavailable with an unknown production date available leaving me with a battery bank box, and access doors that can only hold the initial battery, and no way to actually build out the full battery bank. With like aged batteriesPower Queen did offer to allow me to return the initial battery, but this does not solve the problem of the battery compartment, and the access door cutouts.So, I elected to just keep the single battery and be under powered, until I can find a battery of similar dimensions to buy a full set of batteries to fit the compartment built around this specific battery.Particularly if you are putting in external access doors into some kind of mobile unit, like vans, campers, or RV's buy all the batteries at once and make suet they are going to continue to be available, because you want to make sure that the battery those access and boxes are built will not have to be rebuilt.Power Queen did now clarify, they have bought the materials to do another run of these batteries, but do not know when they will be made, and said they are not on the current production schedule yet per their communications on the issue. They offered to have a single battery produced out of schedule and delivered in approximately a month.If you are like me only wanting to use Lifepo4 Batteries that are in steel housings, please check out the manufacturer and ensure that those batteries are going to be available into the foreseeable future. Particularly if you are building a battery bank for series or parallel where you have several batteries in the compartment.I feel as if I was sold some kind of close out model of battery without notices now, since it is not on the production schedule as they put it. But at least they were willing to try and have a single one built if i was able to wait for it to strive.Because of this, I am revising them back to 4 stars because this really was my fault for not confirming first about future availability. They did make an effort to get me a second battery made and sent out, but not the full bank of batteries,(Original) First the good, This Power Queen battery arrived very quickly, and the seller kept me informed of the shipping progress along the way even.It arrived very well packaged with no battery damage, and a little over 2/3 charged for safety in shipping.I fully charged the battery without any issue, and then tested the batteries capacity using a RV 12v air conditioner that draws approximately 30 amps while using an amp meter to measure actual usage.The battery does seem to have the full 240 ah available, because the one I received is actually a little over 240ah in actual testing. I can't speak to all of them, but I would suspect since the one I received has a little overrated capacity that all would have at least the rated capacity, unlike some other brands.I have never dealt with Power Queen products before, but I must say I am impressed with this companies' customer service and have confidence they would stand behind their 5-year warranty.As stated earlier they kept in contact with shipping update, the battery arrived safely, and is of quality build and actually has over the rated capacity, but more importantly Power Queen reached out by phone after I received the battery to make sure it arrived safely, and make sure there were no problems with the battery (which there was not) and remind of the 5 year warranty incase anything arises in the future.You don't see customer service like this much anymore, I was really impressed by the unsolicited outreach to make sure everything was fine with the battery. As a result, I have no doubt they will stand by their warranty and the fact the battery is of good quality and has an actual capacity over the rated specs I have no doubt this battery company will last into the future.As for the battery not only does it seem to have power above it's rated capacity, but it is very well built, the battery has a steel casing and dual terminal studs allowing for the load to be divided over two separate leads. Those battery terminals come with the bolts already installed so they are not lost in shipping and the terminals also have a plastic snap on cover to help protect the terminals when in use or in storage.It comes with a quick start guide, as well as an actual owner's manual that not only covers the battery installations, charging specs, BMS specs, and over all battery care. It also covers the actual Charge curve for the resting battery so you can determine battery charge level by its resting voltage. (Note lifepo4 batteries have to be checked ate resting voltage, not in use, or when charging they must have not received charge or discharge for over a half hour to get their resting voltage.)The owner's manual also covers some troubleshooting in case there is ever a problem,It also provides contact information in case there is ever a problem, or you need warranty service on your battery.I was torn on Lifepo4 battery brands because it is an expensive outlay if you do not get the quality you need, or the battery does not have the rated capacity which seems to happen with a lot of brands.Ultimately, I decided on the Power Queen although it was slightly smaller than the other that I had narrowed my choices down to.

Battery is wired to 100w solar panel on a roof rack for my Jeep and will be wiring up the 2k inverter as soon as I can get a circuit breaker for the r set up.

This product is 1000% worth the price same as there 12.8v 200ah battery.

Just as good as a Daktoa for a fraction of the price

Great so far
