Works like brand new

So far so good. This one works just as well as a brand new one, and showed no signs of wear when I received it. Obviously, only time will tell if it holds up to as many charge cycles as a new one, but I am totally satisfied at this time. Only wish that there were more of these "Like New" ones available at this great price!

We're so glad to hear that the battery is performing just like new and that you're satisfied with your purchase. We understand the appeal of the 'Like New' options, and we'll certainly take your suggestion into consideration as we continue to offer quality products at great prices.

Fantastic Battery

This is my second Wattcycle battery for my Ham Radio setups. Superb performance for both the 100ah and the 20ah. I have been very impressed with Wattcycle’s product, and their customer service, which has been very responsive.

Disappointed with app and documentation

Before I purchased three 280ah mini smart batteries for my boat, I downloaded the app and read the app description and instructions. I was specifically waiting for a smart version so that I could monitor individual cell voltages to watch for imbalances and the app instructions stated and showed that individual cell voltages were monitored and displayed. When I received the batteries, opened the app, and connected to the batteries the only information displayed was the battery pack percentage of charge and battery pack temperature, not individual cells. This information brought no value to me as I already have a victron battery monitor to provide percentage of charge. When I contacted support they were unaware of what information the app provided and followed up with me after researching. I was unlimately told that the app will be updated but may take up to six months. Also, after the Will Prouse review of the 300/280ah mini, pointing out that the over-current discharge cut off was set dangerously high, I was glad to see on the website that the 280ah mini smart cut off was lowered to 210 amps. However, the manual supplied with the battery lists the over-current discharge protection for the 280ah mini smart as 750 +- 50 amps. What is the accurate number? What and who can I trust? Will the app be updated as promised? After the whole 300ah/280ah issue I wanted to give Watt Cycle the benefit of the doubt but now I'm concerned and contemplating returning the batteries, while I can, and looking for batteries with a useable app and proper documentation.

Never received it.

Never received it, will change my rating if and when I receive it.

The items that was ordered are exceptional, great fit for my boat.

Excellent batteries

I bought 1 of these batteries and a 4 bank charger to swap out my battery that runs my electronics, pumps and lights on my bass boat. I removed 2 AGM 100 AH batteries and put a single 100 AH lithium goin in their place. I made 2 trips to the lake and I was so happy with it I ordered 3 more to replace my tyrolliny batteries. I’m running 4 of them and I’ve been very happy with them. Not only do they provide nice voltage, but they charge fast and they’re really light weight. I took out 5 traditional batteries and replaced them with these 4 lithiums and got more power and eliminated 260 pounds from the back of my boat. The boat handles better than it ever has and hops on pad really quick. I highly recommend these for your bass boat or anything else.

Best Charger on market

I’ve had this charger just over a month now, it is above and beyond what I expected. It’s lightweight and compact compared to other 4 bank chargers. It charges my watt cycle batteries fast and keeps them healthy and charged. And you CANT beat the price anywhere

Works great, good price, and the compact size is perfect for mounting in my boat.

Bluetooth version of 100 amp hour Mini: almost perfect!

Only reason it doesn't get five stars from me is I have an older Android 7 phone (Nexus 6) which is not supported by the BMS Meta app. I was able to get it working on a Kindle fire 7" by using a free app called Fake GPS. This was only possible after "jailbreaking" the Kindle and enabling google play store (a technical process which is difficult for many). If you have an obsolete phone this may be an issue for you and I did not feel like I should have to purchase a whole new phone just to watch the battery's behavior. I purchased after watching teardown videos on youtube to confirm build quality and safety features. Really, this is a five star battery for anyone not using an obsolete phone. After a few weeks, I liked it enough to buy a second unit and hooked them up in parallel for 200 amp hours.

A Perfect Fit for my Needs

I needed an affordable large amp hour battery in a small package. The 12V 280Ah Wattcycle Mini was the right match. This battery went in to a tight fitting Airstream Basecamp 20X trailer battery space. I did not need to make any modifications. I installed it with no issue and put a fuse in place to protect the electrical system. On three-night winter trip in the Oregon Cascades and with temperatures well below freezing, the battery easily was up to all the tasks: propane heater fans, roof vent fan, lights, 12v fridge and device charging. (I am also happy about having low temperature protection for the battery). The 300w solar panels were shaded by clouds much of the time. Thankfully, on this batteries maiden voyage it performed perfectly. Having had battery power anxiety so many times when traveling, it was great to spend more time enjoying the adventure travel experience without sweating about the battery. My next battery related purchase with be the Wattcycle 60amp charger for those rare time I want to fast charge the Mini from an outlet. For now, I look forward to many, many years of service from the battery.

Worry-Free Purchase

Great product

I’ve been very pleased with the product and would definitely recommend

Worked great so far!

Came packaged nicely no issues. Nice they included both bolt sizes if you have two cables on the terminals. Put two of them in my rv and have worked great so far. Would love to get a bigger charger. Maybe one day.

Excellent Battery for My Solar Setup

I purchased the WattCycle 12V 280Ah MINI LiFePO4 battery for my solar power system. It has significantly improved the efficiency of my setup. The battery provides steady and reliable power even on cloudy days. It's easy to install and manage, and I love how compact and lightweight it is compared to other lead-acid batteries I’ve used.

Great Performance for Off-Grid Use!

I’ve been using the WattCycle 12V 280Ah MINI LiFePO4 battery for my off-grid cabin, and I am extremely impressed. The battery holds a charge well and lasts throughout the day with all my appliances running. It's a compact design with high capacity, which is exactly what I needed. Highly recommend it for anyone looking to power their off-grid systems!

Battery switches are excellent and worked great would recommend

Battery is nice but the BMS Meta app quit working just a few days ago. I don't understand why it requires a connection to a Chinese server when it only needs local Bluetooth access. Please fix the app.

Outstanding support

Replaced damaged battery at no cost.

Finally I Chose the Bluetooth Version

I just ordered a WattCycle 12V 300Ah MINI LiFePO4 Battery. But I was worried after seeing many people complain about the top cover. It happened that WattCycle launched the Bluetooth model. After negotiation, I changed to the Bluetooth model of 12V 280Ah MINI. At the same time, the $50 discount originally for the 12V 300Ah MINI was transferred to my Bluetooth model. I am very grateful to WattCycle. After understanding my concerns, WattCycle promised me that if the top cover falls off, they will refund me or reissue it. I am looking forward to my Bluetooth model.

A good product, I'm getting another one.
This battery last me eight or nine days before recharging.

Great power storage in a small package!
I had two 100ah AGM batteries before these and they took forever to charge and I was always watching my battery die too fast now I have these batteries the two of them weigh less than one of my previous batteries and when camping this weekend I never got a low battery alert

Well Done Insurance!!!

A lot of people started to worry about the top falling off, and WattCycle responded immediately. They started to offer insurance. I only had to pay a few dollars to buy insurance. If the battery was damaged during transportation, I could skip WattCycle and claim directly from my insurance company. That was great, and I was happy with the service. After all, shipping damage cannot be completely avoided.

Bad start but good end

I received my WattCycle 12V 300Ah MINI LiFePO4 Battery last month. Although, it has now become a WattCycle 12V 280Ah MINI LiFePO4 Battery. I have to say that I was confused, confused and disappointed at first. However, after understanding the ins and outs of the matter, I don't regret my choice. I am willing to give WattCycle a chance. I have no problems with my battery during use, but even so, WattCycle directly refunded $50 to my account. That's why I am commenting here now.

Ideal for Solar Systems

Powers my solar system effortlessly. Lightweight and compact. Overcurrent protection offers peace of mind.

Damaged During Shipping

The battery’s top cover was loose when it arrived, but WattCycle’s support team handled the issue promptly. They sent a replacement, and the new battery has been performing exceptionally well in my solar power system. It’s been a month, and no issues so far. Highly satisfied!

Damaged in Transit, but Excellent Service!

My WattCycle battery arrived with the top cover opened, likely due to rough handling during shipping. I contacted their support team, and they were incredibly responsive. They offered a refund or a replacement, and I chose the latter. The new battery arrived in perfect condition, and it’s been performing flawlessly for weeks now. Great service and a great product!
