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).

I bought the 100 Ah 24 as a house battery for my newly acquired Starcraft cuddy cabin. As with all lithium/AGM systems, I installed a DC to DC charger to save my alternator and to properly charge this amazing battery. I have have great luck running all of my house systems, VHF radio, lights, bilge pump and a 300 watt AC inverter. The price is right, the weight savings helps with reduced weight near the transom and it supplies more power than I need on this 19' boat. The several independent reviews I watched supported my decision to use this brand. This is my first LiFePO4 install. I wish it had Bluetooth capability but I added a third party such monitor that works great. I can highly recommend this battery.

Received this battery in a timely manner. Well packed and in great condition. Seems to be holding a charge for a long time while being used in an RV. My only complaint is you have to use a bolt for the connection post, and it was extremely short. Since I'm connecting two in parallel, I need to have two connections on two of the posts. The bolt was so short, I had to buy four bolts (M8 x 16mm), eight washers (doubled all of the posts because one made the posts with only one connection extend too much), and four lock washers - all stainless steel. Ran about $12. After getting these set up, everything worked great. Didn't want to give 4 stars because this was an easy fix, and the batteries were a great value all the way around. Just wish they had actual posts to screw the nut on instead of screwing in a bolt.

I replaced 2 lead acid group 27 batteries in my truck camper with these. The 2 WattCylcle group 24 batteries easily runs my 2000W inverter to power my microwave, rice cooker, hair dryer, ect. The weight difference is huge! I've had them over a year with no issues.

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.

So far, this has been a complete fail. I bought 2 100 AH 12v batteries and put them in parallel in a known, good system to run lights and 2000w inverter in a shipping container that I use as a shop. Within 6 months, one battery failed, with low voltage and refusing to charge. I took it off and the other battery worked for another month or so, then failed also. I have contacted customer service and the give the usual instructions and want to know what charger I am using, what load is on the battery and have instructions how to wake the battery up and try to charge it. I've done all of this, and tried with a NOCO Genius 5 charger, but battery is low voltage and faulty. Then, they email me this. Really? Like I even know where an "authorized service center" is, and would have to pay moeny for this in-depth diagnosis of a $150 battery. This is clearly intended to make sure they never have to pay to replace one of their junk batteries. So.. yeah. "Professional Service Evaluation If the issue persists after the above steps, or if internal battery failure is suspected, we recommend sending the battery to an authorized service center for comprehensive diagnostics. Certified technicians will utilize specialized equipment to identify root causes (e.g., damaged internal components) and perform necessary repairs." UPDATE - Company absolutely refuses to stand behind product. Battery is junk and now they are telling me I need to buy a $400 Victron charger to fully charge the battery and determine whether the battery is defective or not. WTF? I put an old Time USB battery in place of this faulty one and it has been working flawlessly in the same system for about 2 months. Company just wastes your time sending ridiculous requests in emails in hopes you won't pursue the warranty coverage for their junk battery. It's going in the trash. Pure junk.
