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.

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.

Works great with my Garmin kraken and lasts all day

This item is a life saver 100 percent recommended I have no issue whatsoever

I just received these 4 batteries and installed them into my solar system. The battery info that comes with the batteries is good for before install charging/balancing and several optional wiring configurations, which is great information. I contacted Power Queen via email for some technical parameters on settings for the inverter and have not gotten a response yet --- hence the 4 stars. {UPDATE: I was contacted by Power Queen and will paste their battery/inverter parameters below. I changed to 5 stars} I set the inverter on some generic lithium settings, but I'd like to be more precise to get the max life out of these batteries. I can't speak to the longevity, which will tell me the value of them. They are working better than my old lead acid so far. They have only been in service 4 days.UPDATE: Bulk Charge Voltage -- 58.4VFloating Charge Voltage -- 55.2VLow DC voltage cut out -- 43.2VLow voltage reconnect --- 49.6VOver voltage disconnect --- 60VOver voltage reconnect --- 56.8VBattery equalize voltage -- Disabled or 57.6VBattery equalize time -- 5 minsBattery equalize time out - 5 minsEqualize interval -- 0 daysMaximum Discharge Current -- 100A (And will be 200A once you added additional 4 units)The total maximum discharge watts 5120W (And will be 10240W once you added additional 4 units)

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.
