I didn't want to give less stars for my mistake. These batteries are great. I started with 2 used Power Queen batteries from a friend. I purchased these to add a new solar array on a van. Be sure you read the description and know what you want. If you want a battery with Bluetooth, make sure you order one with Bluetooth. I was excited to be able to get new equipment I never checked. Not a deal-breaker by any means. You would just have to add a monitor. Safe and light weight and much more resilient than lead acid batteries. Now shop wisely because there are cheaper batteries out there, and the BMS in those batteries are cheap and if you make a mistake you will render the battery unless. Power Queen will contact you and support you whenever you need them. They stand behind their products. Battery group size are the same size as lead acid batteries so be mindful of your space. Follow all directions before you do anything after receiving them and before adding to your system.

This is the best storage battery for off grid folks like myself. I bought my first batteries from Power Queen in Sept 2022. TWO Power Queen 12V 200Ah PLUS that I use for my main 24v solar system. Working superbly for a year and a half now, with ZERO problems from day one. I had my neighbor order these along with the rest of the equipment and one PQ 30amp charge controller to make him a 24v off grid solar system also. We had an initial problem with ONE battery being defective but Power Queen responded quickly and sent a return box and label to send it back and shipped another battery out to me. I charged/balanced the batteries and set the system up and the friend is HIGHLY pleased with it. He had to replace 6 100ah deep cycle batteries this year after 3 years of use, heard me rave about going LiFePO and asked me to set it up and we ordered from PQ because I KNOW they are trustworthy and have a HIGH quality product.

I purchased these batteries and then 1 day they were completely dead. I message the manufacturer and they sold me a charger.They were willing 2 refund my money for the charger. But it worked really good charge the batteries up.I was really impressed with that. Their customer service is outstanding and I would purchase batteries from them again and again.

Works great with my Garmin kraken and lasts all day

I just installed them in my RV., which was a breeze, as opposed to the removal of the very heavy AGM batteries these Power Queen LiFePo batteries were replacing.However, I am unable access the BMS through bluetooth via the Power Queen app. And, there were no instructions in the user guide. A representative from Power Queen sent a post-delivery email, with a link to some FAQs, which did contain a procedure to access the BMS. But, still, no luck after following that procedure. I will have to resort to some alternative monitoring method or tool.The batteries do appear to be operating normally from I have observed, so far. Will test them out this weekend.UPDATE: After further research/reading, I probably purchased the non-bluetooth batteries (which explains the price difference vs a bluetooth model. And, probably something I missed reading through the product description). Bluetooth battery monitor w/shunt needed at this point, so, looking into those, now.Will update again, when I can better monitor battery performance.UPDATE 2: Rating upgraded , since my batteries did not come with bluetooth. Batteries holding up, so far, in the short time that I’ve been running them. Will be installing bluetooth monitor to get more specific performance and status data. Thanks Power Queen for the support!!
