FEENCE 12V 100Ah LiFePO4 Lithium batteries, Built-in 100A Smart BMS, Over 8000+ Deep Cycles Iron Phosphate Battery,with Low Temp Protection Support in Series/Parallel for RV Camper Solar

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!

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.

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.

Bought the 135ah 36 volt for my 1996 EZGO TXT. I've installed a D&D motor and new Alltrax 400 amp motor controller. The battery works fantastic with both. Compared to the big name brands that cost 2000 dollars this battery is well worth the money. Make sure to buy the proper lithium only battery charger, don't make the same mistake I did and get a multi battery type charger. They will not charge the battery completely. Only reason it's only getting 4 stars is because it says it's 135ah but the battery will only charge to maximum 104ah. Other than that is awesome. Why did you pick this product vs others?: Price

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.

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.

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.

This battery works great, I have it hooked to a inverter in my house and when the electric goes down, I plug in a light and the Internet, so we're not in the dark and without Internet. Works great

The battery stopped working and I contacted the seller. David replied within a day with suggestions on how we might reactivate the battery. I tried various suggestions but it would not reactivate. Within another day of reporting the failure I received prepaid shipping labels and expect delivery of a replacement in a few days. It is heart warming to deal with a company that stands behind their product. I highly recommend buying from them

Compre 3 para un inversor de 36 Voltios... funcionan muy bien y su aplicacion incluida muy util para checar estado y carga (%) de las baterias.. las recomiendo y a muy buen precio...

I tested the fully charged battery to confirm that it can deliver the rated 100Ah. I am happy to say that it really did. I only had 50A @12V load to test it but it lasted 2 hours running my inverter. One very obvious advantage over Lead acid battery is its light weight. Time will tell how long it will last. So far, I'm verry happy with it.

Light weight and powerful

Put this in my 12 foot boat powering everything. I can run the brushless trolling motor for days with no charging.
