A+ grade battery, SDS/UN38.3/FCC/CE/ROHS certified, with high standards of quality and safety. 999 times laboratory tested, shock resistant and IP67 waterproof. Lifespan up to 10 years, 6 times longer than traditional lead-acid batteries.
- BCI Group24 Battery Box Size: Lithium batteries are compact and lightweight, with a volume of only 8.4*6.6*10.2 Inch and a weight of only 19.73lbs, meeting the standards of BCI Group 24-31. Compared to equivalent lead-acid batteries, it reduces space and weight by more than 30%, making it a perfect replacement. It takes up little space and is not restricted in the direction of use, making it an excellent choice for use on board.
- Expandable 12V Battery System: Up to 48V and 20.48kWh. HumsiENK 12V lithium battery supports 4 batteries in series, 4 batteries in parallel, or a flexible combination of the two. You can DIY your own power station! Its lightweight characteristics make it ideal for RVs, outdoor activities, boats, off-grid systems and as a home backup power source.
- Built-in BMS Protection: LiFePO4 battery 100Ah has built-in intelligent 100A BMS protection board, which can provide multi-protection, recover from low temperature, over discharge, over charge, high temperature, short circuit and over current without damaging battery performance. When the discharge current exceeds 30050A, it will automatically disconnect the battery to ensure optimal safety and prolong battery life.
- Low Temperature Protection: The 12V LiFePO4 lithium battery can operate smoothly in temperatures from -4F (-20C) to 158F (70C), and automatically shuts down below -4F (-20C), which is especially critical in winter.
- Meet the Needs of Various Scenarios: powering electrical appliances, lighting and electronic equipment required when the RV is off-grid or driving. Marine batteries (fish finders, yachts, trolling motors), garden equipment (lawn mowers, trimmers, etc.), others (children's scooters, LED lights, phones, fans, alarm systems, security cameras, outdoor camping, laptops, etc.). It is worth noting that it is designed with a nylon handle, making it more portable and suitable for outdoor use.
- Fast Charging: Supports 3 charging methods, including solar, generator and grid, for fast charging. 100Ah LiFePO4 battery can be fully charged in just 2 hours, six times faster than traditional lead-acid batteries which take 14 hours. Makes off-grid battery system management more convenient.
- Battery Status Re-activate Tips: Immediately disconnect all loads and parallel/series connections. After letting the battery rest for 1 hour, attempt to activate it using the following method. Low-Current Activation (if applicable): For batteries rendered inactive due to prolonged storage or overdischarge, use a dedicated battery activator or a low-current charger to gently revive the battery. Ensure the charging current remains minimal to avoid damage. Once activated, proceed with standard charging to restore voltage.
- How to bring the voltage back and wake up BMS: Use a 12V 1A Lead-acid charger to recharge the battery and it slowly goes up to 9V (Please note that to watch this process closely to avoid over heat, unplug it if it is overheated), and then switch to the LiFePO4 charger to bring up the battery to fully charged voltage (13.3V-13.6V)

Set name: LiFePO4 Battery
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

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.

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 purchased two of these 12V 100Ah LiFePO₄ batteries and they’ve been absolutely fantastic. The price is almost unbeatable for the performance you get, and the quality has been incredible so far. I run them in parallel to power both an AC unit and an inverter, and they handle the load with ease. They charge quickly, hold power well, and have shown to be very reliable. For anyone looking to upgrade their setup without overspending, these are a must-buy!

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.

Tested many times in my kayak with 55Lb motor and it works perfect. around 4 hours continuously and the capacity remains around 85%. the weight is perfect and all the specifications from the manual are correct. I was using a charger for LIFEPO4 with 10Amps 13.2V of capacity for this 100A battery and works well. now I am waiting the original charger to have it with 100% efficiency.
