12V 100Ah LiFePO4 Battery 1280Wh lithium batteries 12v 100A BMS,Over 8000 Deep Cycle, Support in 4S/8P, for RV,Camper, Solar, Home Energy Storage, Trolling Motors, Boats, off-grid etc

I hesitated to buy this battery for my trolling motor because of the price. On my Minn Kota the higher amp hour deep cycle batteries don't last a full day on medium to high speeds so I didn't know what to expect with this lower Ah lithium. This battery is amazing and although expensive it is worth the investment. I can fish all day on medium to higher speeds and it barely runs this battery down. Although this is not recommended I ran it hard for two days and then checked it. It still had plenty of juice to spare. My suggestion, recharge this battery with a lithium charger after each use as the manufacturer recommends and you will never have to worry about running out of power on the lake. Learn everything you can about lithium batteries and keep in mind this one is only four cells and its BMS is designed so a full charge is only about 75% of its capacity. It's better to use an amp percentage guage to monitor a lithium battery because there is such a small gap in amperage between full charge and discharged.

This is a great "first" lithium battery and is perfect for the vast majority of applications out there that maybe don't require a truly first class, top of the line unit. If I was outfitting a sailboat to cross oceans, I'd probably bite the bullet and buy more expensive name brand batteries with 24 hour domestic customer service and a great warranty. But I'm not - and this is still a great battery at probably 1/5 the price. It arrived at about a 50% charge level. I put it in my Land Cruiser and hooked it up to the solar system (2 x 100watt panels and an Epever MPPT controller) and it immediately started soaking up the full sun exposure. THERE IS BLUETOOTH WITH THIS BATTERY. They don't mention it. You have to contact customer service to get the app name (it's Xiaoxeng, I think) but once you do all that your phone will tell you exactly how much charge you have along with other diagnostics. In 4 hours of full sun exposure on the panels, the battery was 100% charged at around 102 amp hours. I was frankly amazed at how fast that happened - this is my first Li batt and I realized how fast these suckers can soak up the juice. Anyone interested in this battery needs to watch a Youtube channel called "Clark's Adventure" - he is a sailor and an engineer and was in close consultation with this company during development (he's the reason it's called "Feence" and he'll tell you the story). He does a full disassembly, break down and stress test of this battery (along with a dozen others in other videos) and his findings are really interesting. Basically, this is a mid quality but fully dependable lithium battery that you can depend on for most applications. If you're needing to run a coffee maker and a hair dryer and a microwave, then you'll want maybe 4 of these all chained together, but if you're like most people and just need to run some LED lights and charge a tablet or phone, etc., or run a fridge for several days, then this (or two of these) will admirably serve your needs. Customer service was by email and they responded in about 3 hours. Again, this battery DOES have bluetooth, you just have to work for it.

Ordered this battery to be part of a medium 24v solar system, it came quick and well packed with proper foam padding all around the battery. It comes with the terminal screws and instruction manual with the basic info you will need to set this up in your system. LifePO4 batteries are amazing, which is probably why you are looking at these. They can run from 100 to 0% with a very steady voltage between 12-13.5v. As you may be finding, there are so many makes out there, some great, some made with sub par cells and less than quality parts. Not FEENCE, in my opinion they are a top contender in their price range. I preferer to have 2 of these (MOAR POWER) over 1 very expensive battery. Mine came with a 50% (13.1v) charge which I hear is the most stable for storage and shipping. FEENCE offers the complete package of strong construction, quality internal BMS and cables and most importantly performs to its rated capacity after charging it up. BTW Make sure you have a LifePO4 charger, they charge at a slightly higher voltage than car batteries and the technology is a little different. It's well worth the investment. Lastly these are not meant to start your car, but can run anything under 100amps for a long time (think trolling motor, electronics, leds, small motors/compressors)! Also these can be parallel or put in series to work into larger 24v and 48v battery banks. Overall, I am super happy with my purchase!

Battery worked great for about a month. Then It just quit taking a charge. I guess you get what you pay for. Now I’m saving up to get a real battery.

This is a great price. It is comparable to simular batteries costing more. The Bluetooth is convenient and it is sooo light. The other one I had before weighed around 90lbs. This one is under 5lbs for the same rating. I use this for my hydraulic press in my shop. But I also take it with me camping. It's a good buy.

I read a lot of reviews and researched LifePo4 batteries before making my Feence purchase in December of 23’. Initially, I was so impressed that I told others about my new batteries and how they met our needs. For about 6 months they charged well, held a charge and seemed to never quit. We charge them daily. Then I noticed one battery was not charging to full capacity. Fast forward to today, I have three batteries holding a 13 volt charge and one at 5.2 volts. I have attempted to contact Feence to see if the warranty expressed is legit with zero feedback from the company. If they contact me and replace or prorate the battery I will likely change my rating. Photos are attached as proof of proper charging and voltage testing. Edit: Fence contacted me after several weeks of waiting. The person I dealt with asked a few questions and I didn’t hear much for a few more weeks. Fast forward to 12/22. FedEx dropped off a package and to my surprise a brand new battery was inside. I didnt receive a quick response to my issue, nor was there much communication about my battery issue but I have a new battery and I’m happy with that. Based on this I changed my rating from 1 star to 4 star. The issue could have been solved in a shorter time with better communication.

So far, very solid batteries, and great customer service! I have 12 of these in 4s3p and about to add another 200 ah to my array.

I'm a battery freak, and into LiFePO4 types because of their light weight and portability. For the price, this one seemed too good to be true, and I was skeptical, but I took the chance. After charging, this little powerhouse met all my portable needs for a 100 Ah battery (I didn't do any "scientific" testing, just my own experience). It took a little longer to charge than I had hoped, but held a huge charge for a long time, until (my guess) I depleted it to about 12%. Just to be sure, I purchased a second one, in case I got a one-of-a-kind cherry pick, but the second one was just as good. I'm going to get another, but maybe a larger Ah. Since then, a friend got one of these on my recommendation, and he's loving it.
