12V 100Ah LiFePO4 Lithium Battery - BCI Group 24, 15000 Cycles, Built-in 100A BMS, Low-Temperature Protection - Ideal for RVs, Golf Cart, Home Energy Storage, Boats and Marine Applications

Title: Absolutely Outstanding – A Total Game-Changer!I recently upgraded to the WattCycle 12V 100Ah LiFePO4 battery for my off-grid solar setup, and I couldn’t be more impressed. From the moment I installed it, the performance has been nothing short of phenomenal. This battery delivers a steady, reliable 12.8V output and an impressive 100Ah capacity that keeps my system running smoothly, even during peak demand.What truly sets this battery apart is its exceptional durability—boasting up to 15,000 cycles, it’s clearly built to last. The use of A+ grade cells and robust safety certifications (SDS, UN38.3, FCC, CE, ROHS) provided me with the confidence that I’m using a top-quality, secure product. Its efficiency and reliability have transformed my energy system, eliminating the frequent maintenance headaches I experienced with my old battery.Moreover, the compact and lightweight design makes it incredibly versatile for a range of applications, whether you’re powering a home, an RV, or a marine setup. The WattCycle battery has truly exceeded my expectations, and I wholeheartedly recommend it to anyone seeking a long-term, eco-friendly power solution.A definite five stars – this battery is a complete game-changer!

I received the battery in individual boxes with foam padding all around. I read the instruction manual that came with them. It says they ship with only 50% state of charge (soc), so I connect each of them up to my 15A smart charger and set it to Lifepo4 type battery. The charger output varied between 13-14A and the voltage slowly climbed from13.13v to 14.6 when the charger shut down. The first battery took 3 hours and 46 minutes to charge which equates roughly to about 47 Ah. The second battery charged for 3 hours and 38 minutes or about 46 Ah. This gives me confidence in the 100 Ah rating. Time and usage will tell of the quality and durability, so I’ll update this post later. I plan to use these as trolling batteries in my boat. They’ll be connected in series and see a max current draw of 42A. I like to fish from sun up to sun set with intermittent trolling motor usage and duty cycle, so they will get a work out this season. The batteries look to be of high quality, the bolts are a little short (1/2”) and they give you an extra set of the same length. It would have been nice if the extra set was a 1/4” longer. Note the bolts appear to be made of stainless steel, which is a nice surprise given the trolling motor application. The AGM SLA batteries I’m replacing lasted 8 years, so I’m hoping these will last at least that long.Update 7/21/24: I've used these batteries extensively over the past couple of months. They work great. After a full day of hard use the voltage never dipped below 25V (12.5v each in series). I've drained them down as far as 75% depth of discharge (DoD) and with the 6 amp/bank on-board charger they recharge in about 12 and a half hours. I may upgrade to a 10A/bank on-board charger to reduce the charge time, but so far I'm very happy with the battery performance. Note: I try to charge the batteries fully just before use and keep them at ~50% SoC when storing them. The lower voltage during storage prolongs the life of Lithium batteries (unlike lead acid, which should be stored at full potential).

This is the 2nd one I’ve bought for my rv it’s been 4 months and they have been great. Came with both size screws for terminals for attaching a single cable or 2. Came charged at 50% just like manual says. Definitely recommend. Would like to get a 3rd once I can afford it and one of they’re ac chargers. I’ve been recommending watt cycle to people. It’s a great affordable battery.

Quick update. Working great. Kicked up to FIVE stars.Wanted to get a LiFePo4 battery for my sons pellet stove backup system. A-zon had a buy two deal so I jumped on it. I have a Bluetti AC180, but also have a Xantrex 1000 watt inverter. This battery is doing a good job through our testing. Everything we saw about the battery from YT, and Will Prowse have proven to be spot on. I expect to get at least another, but will use this one for a bit first. Shakedown cruise if you will! They are so much lighter and more powerful than my lead-acid batteries. As I said... I am happy now and in a few months I very likely will up date my vote to 5 stars.

I bought two of these 100AH batteries for a solar generator I was building for a reserve back up and to take camping with us. The quality and build was very nice and they seem to be holding up. I am considering buying a few of the 280AH batteries for our motorhome but might go with a larger capacity as I need to run our residential fridge with an inverter. These batteries are well worth the investment especially at their price point.

The switch to a lithium battery in my small camper has been a huge improvement. With the old lead acid battery, you had to always make sure the charge never went below 20% as it would very likely damage or even “kill” the battery. The lithium battery is NOT effected even if the battery drops to zero charge. Also the physical size of the battery is the same as the old one so it fits perfectly in the battery box. Other benefits are that the battery weight is 1/3 that of the lead acid batteries and cost is only slightly more.One cautionary note for cold weather campers. When the weather drops below freezing, the lithium battery will cease to charge until battery temperature gets back up to 32 degrees. This is not to say that the battery does not function, it simply won’t recharge.The only unknown is “What will be the longevity of the new battery?” The company Claims up to a 10 year life but even if it lasts half that time, it will be well worth the investment.

The battery was delivered earlier than estimated date. It charged up nicely. I like its lighter weight. Installed in my RV and powered everything normally. The quality of this battery seems very good.
