Power Queen 12.8V 190Ah LiFePO4 Battery, Built-in 150A BMS

My interactions with the 190 amp battery and Queen team has been most enjoyable. I started out with four of the units for testing. Then because of the successful testing I doubled my batteries to eight. Finding that they meet my needs, I again ordered four more units. I have a 10,000 watt array and needed additional battery storage. It was not a hard task for me knowing that they were/are what fit me best for the upgrade. Thank you Queen team!

This photo is of battery No. 5 and No. 6. I have them on an 2k Inverter. The other four are on a 3k inverter. These batteries are really good. One will run a medium sized deep freeze about 24 hours!

I just got my 5th Power Queen 190ah battery and really love it. Shown is the pic is the start of a smaller system, I will probably use 3 of them for this system. That is plenty of power (ran a lot of tests) for my two full size freezers and a fridge for backup power. I am going to use the first four batteries for a window ac unit for power outages.

Arrived quickly,very nice looking battery , would buy again . Thank you very much

Replaced heavy AGMs with these, I basically tripled my capacity and halved the weight. So far no issues.

Everything came as promised I did though asked to get a refund on the tax because Solar isn’t taxed in Arizona or Minnesota I did give him the information he needed but still no tax relief

Just got my fourth last 190ah 12v battery, getting ready for 24v! I really love these!

Excellent look, weight and specifications!

I bought this battery back in July (2022). Installed it in my boat as a house battery. It allowed me to run two small boat fridges for 30 hours. No need for a cooler. So I just bought another one this month (Oct 2022). Two batteries of this size. ( 12.8 volts 190 amp hour) will run my two fridges, water pump for showers when doing an overnight. Also the vacuum flush toilet. Set. Can't wait till spring, when boat goes back in. Also a big thanks to Mike the service tech. Had couple questions. Had the answer the next day.

I haven’t done any heavy lifting with Them yet, but they have done everything I asked them to! Just ordered my second and will get a third!

Still learning about these big batteries, first one, everything is what I expected and hoped for so far, only one deep cycle in. Plan on getting more of the same. I would definitely recommend it.

Amazingly lighter than my 92A lead acid battery. Would like to know what kind of battery box this goes in though!

Ran test on discharge time under full load and was very happy with results.

What a high quality product!

I installed the battery on my 30 foot RV because we love to primitive camp. Unfortunately I have no more trips planned this year. Will take it off the camper and keep in the house for emergency power usage over the winter. Saw the video by Professor Hobo on Youtube and the tests he put it through impressed me on the quality of the BMS. This is the reason I purchased your battery. Looking forward to really putting it though next years camping season.

Fantastic build quality and they out performed all of my test. Would recommend and will definitely purchase again.

I currently have a small solar system with lead acid storage batteries on my little off grid summer cabin in the woods. I am now upgrading my solar array and switching my power bank over to LiFePO4 batteries. I have studied almost every battery available as to how they are assembled, which components they use, warranty, and especially price. There are many good batteries out there and there are junk ones that will fail in a year or so. I bought the Power Queen 12V 190AH battery based on its sale price, quality of construction and five year warranty. Ok, it was good looking too. The first thing I did was to fully charge the battery (you have to use a special charger for all LiFePO4 batteries by the way or you will ruin them). I then did a capacity check of the actual battery output. Not surprisingly, the capacity was actually greater than advertised by almost 3%. You get extra for what you pay for! So I have now added a new solar string hooked up to this battery and a Victron charge controller. The capacity of this one battery is greater than all the golf cart battery group I started with years ago. So what do I think? This battery was the best quality for dollar spent when I bought it. Things change so quickly in this market but I am extremely happy with my purchase.

Fast delivery boxes were packaged well battery seem to work as described

I'm using this to expand the capacity of a 2000W solar power station. The Power Queen 190ah battery is the right price and is working great.

Ok so purchased this based on the review by Hobotech. To be clear nothing fancy on the outside but definitely seems to have quality cells and BMS. Easily cranks out 125 amps to my 2000 watt inverter and bet it has a lot more to give. Will be buying more.
