      Best LiFePO4 Battery Yet
      Reviewed in the United States on May 4, 2026

      Full content visible, double tap to read brief content.

      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

      Going from 6 of the normal 6 volt batteries to 3 of the 12 volt batteries of these has been a great improvement in my 36 volt golf cart. The weight reduction was hundreds pounds to begin with. The length time between charges is tremendously improved. Power is better and don't diminish until batteries are very low on charge. Just all around great so far. I will never go back to regular batteries after using these.

      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.

      Battery was very reasonably priced. Reviews were good. The battery came packaged very well for shipping. Package arrived on time. I ordered this battery to incorporate into my DIY power station that I built. This 12 V battery along with my 2000 watt inverter will power almost all of my major kitchen appliances including refrigerator, washing machine, microwave, instapot. Naturally, it will NOT do all at one time, but will handle each load well. My last test with my DIY system is with an 8000 BTU window air conditioner. So far, my power station has been operating this air conditioner for 11 hours and the battery has only drained to 50%. (this A/C is operating in Eco-mode, which allows both fan AND compressor to shut off when the thermostat is satisfied - It has kept my bedroom at a chilly 64° for the entire time). The Bluetooth part of this battery is a pretty neat feature. Paired with the battery app it generates some pretty useful information while the battery is being used . I recommend this battery highly to any DIY enthusiasts or if you want to incorporate it into your solar power system for home or RV/camping.

      Good battery for the buck.

      Battery was very reasonably priced. Reviews were good. The battery came packaged very well for shipping. Package arrived on time. I ordered this battery to incorporate into my DIY power station that I built. This 12 V battery along with my 2000 watt inverter will power almost all of my major kitchen appliances including refrigerator, washing machine, microwave, instapot. Naturally, it will NOT do all at one time, but will handle each load well. My last test with my DIY system is with an 8000 BTU window air conditioner. So far, my power station has been operating this air conditioner for 11 hours and the battery has only drained to 50%.

      Battery worked the first few months then went dead. I attempted to recharge it and after a few days again it went dead. Battery had issues connecting to the app and I believe this lead to it not charging correctly. Seller was difficult to work with taking long periods to respond stating they were always on a holiday. I couldn’t recommend this battery for these reasons. Personally I would not waste time nor money on this battery and but from a reputable source.

      Hi, I've owned this battery about 6-months and have put it to work daily in my off-grid solar generation system. I've used it solo stand alone with my 12 volt inverter and I've used it in my sophisticated battery bank setups for a 24 volt inverter. In summary, this battery is of great quality. It yields great production and it wouldn't surprise me that the number of cycles they promise is true and therfore this battery yields tremendous value in the LiFeP04 battery 🔋 market landscape/space. The company and its engineering is very precise and no nonsense as is evidenced by thier labeling it a 12v 100ah instead of 12.8v 100ah as the .8 volts can really just be left off of all the batteries for a matter of practicality but it hints at the minds behind this dynamo battery product.
