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.

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.

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.

Works good, lighter than lead acid without risk of leaking. Have seen lighter but not necessary for this application. Good price. Bluetooth function is really nice to know voltage. Does need special charger.

I've purchased a total of 17 batteries of this model. All are in perfect condition and perform as specified by the manufacturer in terms of capacity. The finish and build quality are excellent. I'm very happy with this product.

It came faster than expected.......very lite weight I'm satisfied with the battery and would recommend it...👍👍

Well I’d have loved for his battery to have been as great as the other reviews, but unfortunately I can’t. I ordered both a 100ah lithium and a 20a charger. I received the battery but not the charger. I’ve contacted both power queen and Amazon how just directed my message to power queen. No response.Buyer beware. I’ll be filing for a refund and will have to find a different charger from another company.
