Review: Rated high by YouTube’ers - 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 desertcart 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.
Review: Increased capacity in my Rv - This battery was recommended by my social group as a replacement battery for my solar system. They were spot on. Battery life and functionality were increased, easy to install, and the price was much less than the other well known competitors. Size was not an issue it fit my compartment perfectly. I highly recommend. These do go on sale as well so watch the prices.

## Features

- Durable 12V 100Ah LiFePO4 Battery: 5000 cycles at 100% DOD deep discharge. A+ grade battery, SDS/UN38.3/FCC/CE/ROHS certified, with high standards of quality and safety. 999 times laboratory tested, impact resistant and IP67 waterproof. Lifespan up to 10 years, 6 times that of traditional lead-acid batteries.
- BCI group 24 Battery box size: Lithium batteries are compact and lightweight, with a volume of only 8.2*6.6*10.2 Inch and a weight as low as 23.2lbs (10.5kg), meeting the standards of BCI group 24-31. Compared with equivalent lead-acid batteries, it reduces space and weight by more than 30%, making it a perfect substitute. It takes up little space and is not restricted in the direction of use, making it an excellent choice for use on board.
- 12V battery system is expandable: Up to 48V and 20kWh. 12V 100Ah 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! Due to its lightweight characteristics, it is very suitable for RVs, outdoor activities, boats, off-grid systems, and as a home backup power source.
- Built-in BMS protection: LiFePO4 battery has built-in intelligent 100A BMS protection board, which can recover from low temperature, over discharge, over charge, high temperature, short circuit and over current without damaging battery performance. When the discharge current exceeds 300±50A, it will automatically disconnect the battery to ensure optimal safety and extend battery life.
- Low temperature protection: The 12V LiFePO4 lithium battery can operate smoothly in temperatures from -4°F (-20°C) to 158°F (70°C), and automatically shuts down below -4°F (-20°C), 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, which is portable and more suitable for outdoor use.
- Fast Charging: Supports 3 charging methods, including solar, generator and grid, providing fast charging. 100ah LiFePO4 battery can be fully charged in just 2 hours, six times faster than traditional lead-acid batteries that take 14 hours. Makes off-grid battery system management more convenient.

### ⭐⭐⭐⭐⭐ Great reserve battery
*by R***7 on January 21, 2026*

Using this as a a huge battery bank to top off my Jackerys. At 4kw this battery will hep me keep all my many power stations charged. I charge this batter either through 400 watts solar or by using a 40a lipo4 battery charger. With all my planning I can go about 2 days off grid before I need to use the HumsiENK battery.
