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.

Excellent battery and value for the money. Runs my mobile grooming trailer wonderfully. The app is nice and straight forward to use. My only complaint is that it seems that you have to be within 5’ or so of the battery to be able to connect to the app, not really a big deal for most I’m sure, but I like to turn it off between stops.

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.

Battery is perfect for a backup solar generator. Runs true to its capacity.

The battery arrived broken. We didn’t realize until we were on the road in the middle of a national park. We took it to a technician thinking our travel trailer is broken who diagnosed a dead battery even though the app said it’s 100% charged. This ruined our trip and we paid $215 for a technician to have a look at it. Now we need to print a label and then return the battery in order to get a refund. Absolutely ridiculous!

I purchased 4 of these 12 volt 320Ah batteries, to connect in series for a 48 volt system, it was around black Friday sale time of year, and these seemed like the best capacity value to me. When the 4 batteries are connected together in series, it seems difficult to try to keep each battery with the same charge (balanced). The bms does show each cell voltage in each battery, and while they are usually fairly close to each other, the overall battery percentage reading seems off by up to10 percent between the different batteries, making it confusing to know where the battery charge is really at, and often get a -pack over current warning, yet the battery percentage shows like 92% or so. I have tried adding a external balancer, but that did not make any difference. The batteries were fully charged seperatly before connecting them together in series. Now I pretty much just let them charge themselves the way the bms wants to, and ignore percentage readings, and probably will reduce charging voltage a little so some don't get over current, but they will not have quite as much capacity then. Regardless, they are working good for solar powering inverters. I have since purchased 48 volt batteries also, and the bms seems to handle the charge and percentage number better in each separate 48 volt battery, since they are not connected together in series. I believe the battery brand seems to be a good value and price range ratio

using it in home made battery back up system to supplement generator. after one use battery died. not help from Humsnek or Amazon. have now a 25 pound square anchor and no boat. without seller backing this product is useless Humsinek finally contacted me. it seems that is was not setting it up properly. now running fine and testing it powering a light and a 70inch tv. changed review to 5 star.

as described

Is as described was well packaged and delivered very quickly

Excellent buy! Good battery and above expectations customer service

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
