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 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.

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

These batteries are awesome for my bass boat trolling motor. Easy charging and longer lasting than lead acid batteries.

I purchased these batteries and few months ago and had my system professionally installed less than 4 months ago. 4 days ago, one of the batteries BMS started malfunctioning and won't allow it to charge, and it flips on and off in discharge protection mode. I reached out to the manufacturer with emails. They have called me and request that I send an email. Its just a runaround and have gotten nowhere but 4 days of no electric. Edit** got a response, but it's 1 email per day, with no resolution so far. Just the runaround. It was expressed that I have no electric day one and it doesn't seem to matter. Just getting excuses. Worst customer service experience I've ever had. They even said there gotten no emails from me... see photo.

I bought these batteries for my travel trailer for the time I just want a fan, lights and my TV. When no other power source is available. So far, they are working as they are suppose to.

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.

This battery and a 3000w sine wave inverter will power your van or camper fully. Add solar and go for days!

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

Is as described was well packaged and delivered very quickly
