   These batteries are performing well and hold a charge better and longer than others I have purchased from the inner net. Their website is excellent and I have asked questions and always get a response within 24 hours. So far, I am super satisfied with Power Queen batteries and the Power Queen Company. Thank you.

   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.

   Very pleased with this purchase, no issues powering my RV via solar, I use them in parallel to get 200 ah, fast charge. I’m buying more for my bunk house off grid.

   These are installed on my new emergency home solar power station. When I received the batteries the charge was 13.3 on both of them. I have another station built with a different LiFeP04 battery which I used at 1st to start up and check the system. That battery charges faster and the charge reaches 14.4v during the day. I’ve never been able to get the Power Queen’s past 13.7v plus the voltage drops fast. I have a Lithium battery charger that I used on both batteries separately to fully charge and sync them. I let them sit hooked in parallel for 12 hours before hooking them up to the system. I’m no expert on solar batteries so I’m not sure if this is all OK. I do know that in the old Power Queen users guide had a chart showing that 13.5 is a full charge as seen on YouTube reviews. Why did that cut that page out?, I’m not sure . The lowest voltage has been 12.6 v hooked up to my inverter with the freezer plugged in. So I’m not sure if these are working properly. Only time will tell if they will be good. Update; The batteries never reach full charge according to both my battery charge status gauges. 3/4 is the best @ 13.7v under charge is the best I can get. The batteries are discharging as they are plugged into my Solar Power Board/Inverter and Freezer. I’ve been helping them in the morning by plugging into my charger. They run down to 12.6v at night and recharge to 13.7v at peak PV charging hours. So, I’m still not sure about them. Update2: Batteries seem to be charging better. They reached full charge 2 days over the weeked with my battery status gauges both at 4 bars. They are holding at 13.3 overnight at rest with the inverter shut off. I’m still concerned about them not hitting 14.4v while charging. Are they waking up? I don’t know… Update3; The batteries are now charging normally hitting 14.5v under charge and resting at 13.3v. I can’t tell you why. Whatever was preventing them from charging correctly has fixed itself with daily charge cycles. Its taken a couple of weeks for this to sort itself out…

   Seldom do I make a product review but I am happy to do it this time as the seller of this product needs a shout out.
   First , I am very much satisfied with the performance of the batteries , working and rated as advertised, shipping is fast, customer service is excellent and not to mention that the prices is so affordable compared to other batteries on the same class.
   Being happy with the experience , I ordered same item as I have decided to expand my system. I realized that I could have saved as much as $91 due to lower price and coupon that became available later. When the package arrived which is quick as usual, I contacted the seller without difficulty and they were too considerate to offer me that full amount as refund. This seller has earned my loyalty and trust.

   Je vie dans mon van et j’ai acheté cette batterie il y a quatre mois environ, après la modification de mon installation pour brancher une batterie lithium lifepo4, c’est carrément beaucoup mieux que les batteries acide pourtant j’avais une agm avant, mais là c’est le jour et la nuit : plus d’autonomie, chargement plus rapide, il ne reste plus qu’ a voir dans le temps.
