I recently purchased the Power Queen 12.8V 100Ah LiFePO4 Battery for my off-grid solar power system, and I am absolutely thrilled with the results. This battery has exceeded my expectations in every way, and I couldn't be happier with my purchase. First and foremost, the battery's capacity is impressive. With 100Ah, it provides ample power to run my essential appliances and devices, including lights, a refrigerator, and even my laptop, for extended periods without any worry of running out of juice. This means no more power interruptions, even on cloudy days! One of the standout features of this LiFePO4 battery is its durability and longevity. I've had it in my system for several months now, and it's been performing flawlessly. The build quality is top-notch, and I can tell that this battery is designed to withstand the test of time. Plus, it's much lighter than traditional lead-acid batteries, making it easier to handle during installation. Charging this battery is a breeze. It recharges quickly and efficiently, and I've noticed a significant reduction in energy loss during the charging process compared to my previous batteries. This translates to higher efficiency and more usable power for my needs. Safety is paramount when it comes to batteries, and the Power Queen LiFePO4 doesn't disappoint. Its advanced safety features, including overcharge and over-discharge protection, give me peace of mind knowing that my investment is well-protected. I appreciate that they've taken these extra steps to ensure user safety. Lastly, the customer support from Power Queen has been outstanding. They were responsive to my inquiries and provided helpful guidance during the setup process. It's always reassuring to know that there's a knowledgeable team behind the product. In conclusion, the Power Queen 12.8V 100Ah LiFePO4 Battery is a game-changer for anyone looking to power their off-grid setup efficiently and reliably. Its impressive capacity, durability, ease of use, and safety features make it a fantastic investment. I wholeheartedly recommend this battery to anyone in need of a dependable energy storage solution. It's a true gem in the world of renewable energy products!

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.

So far no complaints. Installed in my camper, wired them up. They have run my camper for 2 days with no issues. My solar panels charge them efficiently.

I've had these for a couple of years now. Two of them for my trolling motor with no issues and they seem to last about eight hours at least. When I bought them, they were less expensive.So I consider it a very good value.

Have 6 of these powering my shop thru my Sungold power 3000 watt inverter. Ggeat batteries for the money have had no issues over the past year or so. Good product that I would recommend.

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...
