HumsiENK 12V 150Ah LiFePO4 Lithium Battery BCI Group31 Bluetooth- Built-in 110A BMS, Deep Cycle Battery for Solar, RV, Marine, Off-Grid Applications - 15000+ Life Cycles, Safe & Lightweight

So far this battery has been awesome, Bluetooth capability makes up for not having a built in display screen which wouldn’t have worked out at well since it is going in a battery box. The range is about 20 feet and has been easy to control while installing it, you can stop it from discharging through the app to make it safer. It has a bunch of built in safety parameters and I’m hoping is going to last for a long time. It came with 2 sets (4 bolts in total) that easily screw into the pos and neg terminals, and has a carrying strap build onto it already so it’s easy to carry. 12v output is good, it’s actually a bit higher but you can use the app to adjust it if you need to. I have only owned it a little over a week and so far no issues with daily use.

I bought four of these for a solar battery bank. Due to health issues it took me months to even get around to putting my syetm together. Even after months of just sitting in their boxes, they had a full charge! I was shocked. They are now part of my solar array and seem to be working very well. They certainly appear to be a solid, quality product.

I bought these for my boat. I watch a few videos on them, they opened them up and they seem to be well made and work well at a great price. The app works easy for me I can see battery levels, it is one at a time but that's ok. I am looking to upgrade my 12 volt trolling motor on my boat, when I do I will buy more of these to meet the needs of the new 36 volt trolling motor. Because they are so much lighter I can run all my electronics are on there on lithium battery separate from the trolling motor. Thanks.

using it in home made battery back up system to supplement genes. so far works as needed. just ordered a second on to double capacity. love the cell phone app. recommend it for this type of use.

So far I am very impressed with this little battery. The size is smaller and lighter than the car battery that came in my used rv. It is hooked into my solar supported system, time will tell how it holds up. BTW, it arrived 13.1 volts, fully charged which made me happy

Great Battery for my RV replaces flooded deep cycle batteries in my Motorhome. They make it usable for boondocking but be aware you need to replace your RV voltage converter to one that is compatible with LiFePO4 batteries but well worth the price. If you only use 1 get the 200A BMS if you want to use it to start your Generator. Make sure it will fit in your battery box I had to modify mine but it was not to difficult to do.

I’ve had them for two months now and they work as they should and provide plenty of power for AC and all your other RV needs

Got 2 12.8v 320ah batteries, after charging the 1st one (at 280watts) for 45 to 50 min to 63% full the charger start to flash that the cable’s were disconnected (not so), though my charger was bad ( again not so) the 2nd battery is now charging just fine. The only thing I can think of is that an internal cable inside the battery must have came loose. I try again later. More in likely will be returning to Amazon for a replace Updata contracted HumsENK so far they are being helpful about the problems I having with on of the batteries. Will give another updata when resolved hopefully I can give updated 4or5 star rating

Is as described was well packaged and delivered very quickly

Lots of power runs the camp very well I ran 2 in circuit and one 2 in parallel with the first 2 because there was too much power for my 3000w inverter running 24V Runs my camper all night without the Jenny or gas appliances kicking over

Excellent buy! Good battery and above expectations customer service
