HumsiENK 12V 100Ah LiFePO4 Lithium Battery, 1280Wh Energy Built-in 100A BMS

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

Very happy with the battery and customer service. When using my inverter to run a shop vac, 780 watt draw for 15 minutes, one of the terminals overheated. Called customer service and they suggested was likely due to dirt in terminal contact or not enough contact area. They sent out a new replacement battery immediately which I had in a few days. Amazing service !! Turns out there are two different length terminal bolts included with the battery and I had used the shorter one so perhaps too little contact area causing overheating? Suggestion use longer bolt to get the most bolt to battery terminal overlap. Despite the overheating the battery performance was great. Only used 13% of battery capacity powering shop vac for 15 minutes. Ultimately the battery is a replacement for my RV group 24 size battery. ThIs 100AH battery is a perfect fit in my RV battery box and a terrific upgrade over the original lead/acid deep cycle.

Great battery. I would highly recommend this purchase

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.

I was skeptical about buying cheap lithium batteries but ive been using it with a newport 55lb on my 12ft jon boat and I usually go for 6 hours on lakes. The most ive used on a 8 hour trip was 50 percent. 6 hour trips I used 20 to 30 percent. The app easily connects and has a lot to it. The only thing I would say is cheap about it is the housing. Other than that its a great battery for a trolling motor.

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.

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.
