Upgraded 100A BMS & Low Energy Consumption
- Upgraded 100A BMS has anti-overcharge, over-discharge, overcurrent, and short circuit, allowing the lifepo4 battery 100ah to have a strong and stable performance in each cycle.
- 3 Ways to recharge the battery：1, CHARGER: 12V( 14.6V )20A LIFEPO4 Charger 2, Solar Panel （Recommend ≥300W) 3,Generator（Add a 20A DC to DC Charger).
- The maximum discharge current is 1C.
Support 4P4S and Have High and Low Temperature Protection
- A built-in thermal cutoff prevents charging above 140°F (60°C) and enables low-temperature shutdown protection for extreme temperatures below 32°F/0°C. It protects the battery from freezing temperatures for longer battery life.
- FIUNIE LiFePO4 battery 12V 100Ah supports up to 16 identical batteries in 4P4S connection, enabling the building of a max. 48V(51.2V) 400Ah battery bank with a max. energy output of 20.48kWh and a max. power output of 20.48kW. With fewer limitations in parallel and series connection, the FIUNIE lithium battery is more versatile in DIY battery systems than smart batteries that only allow parallel connection in the market.

Works well in my Jon boat. It effortlessly powers my trolling motor all day, 2 fish finders, and electric start on my engine. This battery lasts a very long time. I did have a issue with the bms system on the battery. I contacted the seller and they provided me good customer service and they fixed my battery remotely.

Incredible!! My audio system demands 2700watts max and 1900 watts ish continuous power. This is a secondary battery for my audio Running stock 130amp alternator on a new nissan Altima. With everything running on car and sitting in park audio full tilt the battery never drops below 99 amp hours/98% charge. Driving it never drops below 101amp hours battery caps out at 103 amp hours. Car never drops below 14.1 volts driving and never lower than 13.9volts parked Threw it in car one month ago new at 60% charge. Drove around music full tilt for a hour and it kept continuously building charge to 100% while taking a heavy drain. Before this battery car was dropping down to 12.4 volts while driving ! Even at 4 degrees outside the charge was still 100% sitting in cold car trunk outside with freezing rain all while still showing 32 degrees for battery temp on the app. I bump driving 3 hours a day and 1 hour roughly parked. Never seen this battery drop below 98% charge since February 1st 2025 it's now March 9th. I'm gonna gift this battery to some friends and family. The app is really cool can control if it charges and discharges and live monitor every thing on battery via Bluetooth app. is Bulky but at 103amp hour capacity still lighter than the car audio 30amp hour agm battery I was using before

Replaced a tradition batter with this. All I can say is it was worth the extra cost by miles! Charge lasts exponentially longer and is so light! It's great to be able to use the app to see the state of the battery as well. Love it!

Love this battery. Runs my 12 volt 38 qt refrigerator for more than 3 days. Has app to check battery power. Lighter than typical battery. Would purchase again

I like that there is a Bluetooth app, and you can check on the battery status anytime.The cost vs a lead battery by far is reasonable as you do not have to replace the battery every 3 years, which seems to be what I found. My old battery, which was lead for my RV and I wanted to upgrade. The battery did fit into the location that it was designed for. Part of the upgrade was also my old converter as that was old and my lights in my RV were flashing when I turned on to many lights at once. I made sure it was Lithium compatible. The connection uses screws not battery posts, so the size fit my RV fine, which does not use car like terminals. I lost power from my converter as the power was off to my RV for 3 days , We live in it full-time and the battery did very well and kept things lit up as expected for days. I need my 12 volts on to run my propane refrigerator, so when the power went out for a few days, I had no worries about loosing food. As well as not worrying about lights being on at night.

The battery is great. So nice to have something lighter that the lead acid battery we have used for years. Significantly lighter and upgraded from 65 amp hours to 100. The app works fine with telephone bluetooth so you know exactly how much capacity is left. We use it with a trolling motor and when moving, it tells you approximate duration at that speed. You can also turn on and off both the charging mode and the discharge mode, which is probably useful for some situations and for safety when not in use, but we haven't used either. The app shows you the power left on all four cells and has other information that may be useful, but we are mostly just interested in the total percent of power left. Does not appear to have any battery memory issues and fully charges even if not fully discharged. The only minor negative for us is the lug nuts. They are just nuts into the top. We replaced them with some brass lugs that look like regular auto battery lugs and also have a screw in the top, so now we have our trolling motor connectors on the bottom of those lugs (with threaded bolts through them) and our fishfinder clamps on the lugs and have the top screws available. With that setup, this battery is perfect for us.

I replaced the two AGM batteries for my 70 ft lb, 24 volt autopilot trolling motor. I use an onboard two bank li-ion charger, and on the water, in six hours of fishing in windy conditions where the motor was working to hold position or course ALL the time, the batteries were still at 95% charge. I really love the blue tooth app .. it shows the % charge for the battery, the battery voltage, and the charge condition of each cell, eliminating all the guesswork about the charge and battery condition. My onboard volt meters show 13.3v at full charge, and at the end of the day, I have never seen them below 13.1. Not to mention the 100 # of AGM batteries that went away. A good value for their price point. My only complaint is that they may be damaged by sub zero (below -4 F), so they must be taken to warm storage for the winter, but at 25# each, that is no great hassle, unlike lugging the 65# AGMs around. And, I should get more longevity than the 4 yrs the AGMs gave me.
