12V 150Ah LiFePO4 Lithium Battery with Bluetooth, 1920Wh Group 31 | Built-in 110A BMS, 15000+ Deep Cycle Battery, for Solar RV Marine Off-Grid Trolling Motor Applications, Safe & Lightweight

Great Great value LiFePO4 battery with useful Bluetooth app! I recently purchased the Humsienk 12V 100Ah 1280Wh LiFePO4 battery and I’m very satisfied with the quality. The build feels solid, it’s much lighter than my old lead-acid batteries (around 23-26 lbs), and it’s a perfect drop-in replacement for RV, solar, or marine use. What I like most is the Bluetooth connectivity and its own dedicated app (HumsiENK Smart app). Being able to monitor real-time voltage, SOC (state of charge), current, temperature, and other parameters directly from my phone is super convenient. The app connects easily and gives me peace of mind. So far the battery performs exactly as advertised — holds voltage well under load, charges efficiently, and the built-in BMS with low-temp protection works great. I’m really hoping it will deliver the long cycle life (thousands of cycles) that LiFePO4 batteries are known for. Overall, excellent quality for the price. If you’re looking for a reliable, smart lithium battery with app monitoring, I highly recommend this Humsienk model! value LiFePO4 battery with useful Bluetooth app!

These batteries are flat out awesome. You're getting a 4kW battery at a great price point that still has Grade A+ LiFePO4 cells. Each battery has four of them. The Battery Management System (BMS) is absolutely fantastic at its job. The connectivity between the BMS and the HumsiENK app works perfectly, always connects quickly, and updates the data quickly too, several times a second. I'm not kidding when I say the connection to the app works flawlessly. It has pages for dozens of possible alarms or failures or protection measures applied. The BMS is wonderful and keeps the battery safe, and easy to monitor. You can even check out individual details for each battery cell. The weight is not too bad. It's about 55lbs so you'll need to be careful and lift with your legs, but for the amount of power you're getting, its weight is fantastic and makes it very versatile. The size is also compact and easy to store and use. I wouldn't say it's a "mini" battery, but it's a fairly compact size. Battery specs and technology is critical and this battery delivers. Actually, I have 3 of them now and all 3 have a real capacity as measured of around 4150 watt hours which is absolutely fantastic. You cannot find a better battery deal at this price. The seller is also awesome and willing to work with you on any issues. What an awesome battery and product. Truly amazed at it's capabilities

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 have 4 of these now and intend on getting more as they go on sale for about $120 each being charged by my 12,000 watt solar panels and Mr Power MPP charger. Set up now in parallel outputting 12-14 volts to a 2000 watt modified sine inverter to power my 2 dead freezers. I have a timer on the 110 volt circuit to power freezers for 12 hours during the day and shut off saving battery storage for 12 hours at night. Freezers can be off for 2 days before showing any signs of defrosting. As I get more batteries I intend to output 24 volts using series/parallel battery connection and powering my 3000 watt pure sign inverter that I used to use 6 golf cart batteries to power. Their life was about 4 years and also were in my golf cart. They used to be $120 each but went to $150 recently so no brainer to go to a 10 yr Lithium battery that’s has more reserve power. The only issue is about the battery management system built into the battery to protect it. It does work as designed but what that means is that when the voltage goes down to 10 volts or so the BMS shuts the battery/batteries down and even if the load is removed they will not charge back up until you wake them up. You do this by applying for a few seconds a 12V DC input from a source like a Jump starter box. So this requires monitoring your system. I put a battery powered no AC alarm I got from Amazon on the inverter output to alert me when this happens. This occurs in cloudy weather. Yes there is a beep from the inverter but not loud enough to here in the house from the garage.

Purchase battery and light March it was paired with a 50 lb thrust Minn kota brand new from early April to now I've had the battery in use about 20 times charged only nine times but I went out day before yesterday it worked long enough to get me a hundred feet offshore so I had to paddle back I'm 73 I really didn't like that so I pulled the battery bought it home put it on the charger it charge for like 5 minutes they said it was charged just to cover all my bases I took my DieHard marine battery with me and it did the same thing it let me get about 30 ft off the bank and just motor shut off couldn't get any power from the battery at all thank God had to die with me or I'd have been floating away in the wind then I guess they really didn't read the return policy I thought I had a year no so if you don't buy the warranty you'll be in the same boat. Just so you know the boat it was pushing was a 10 ft pond prowler with just me and it in about 10 lb of equipment when it worked I could go four or five days six hour days without a problem now I get two three minutes and it's done

So far this battery operates as advertised. I paired it with a Gsskny 2500 pure sine wave inverter, 25 amp unit for our sump pump. It charged to full capacity the first time in under 12 hours. It's a lithium ion battery and half the weight of a conventional battery.

The bluetooth option is great to check status on your phone. This company does offer military discounts on their site. I believe 6%. The battery is priced very well.

Working well on my gd imagine travel trailer. Far superior to cheap lead acid from factory. However was a challenge getting output to reset after initial charge and getting my units solar charger to reset to lithium.
