Doesn't seem to hold a charge.

We are sorry that you faced this issues, please contact us via service email asap.

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.

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

Ideal for Solar Systems

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

High Energy Density

EVE cells deliver outstanding energy density. Lightweight and easy to handle. The overcurrent protection works great.

Great for Off-Grid Living

Installed this in my off-grid cabin. Compact size and high energy density exceeded my expectations. It powers my appliances smoothly, and I feel safe with the overcurrent protection. I’ll be upgrading to Bluetooth when available.

Excellent for Solar Storage

I’ve used this battery in my solar setup for a month now. The EVE cells are efficient, and the lightweight design makes handling easy. Overcurrent protection is a great safety feature.

Long Runtime

Runs my appliances for days without a recharge. Overcurrent protection is a nice safety feature. Looking forward to the Bluetooth model.

Great for Off-Grid Setup

EVE cells provide consistent power for my off-grid cabin. Small size fits snugly in tight spaces. Highly impressed with performance so far.

Compact and Reliable

Perfect size for my camper. Lightweight and easy to install. Runs all my devices effortlessly. Highly recommend for anyone needing a powerful yet compact battery.

Good product

Well built battery and I love the light weight. I only used it one time so far but it worked great. Waiting for spring to get more use out of it.

Thank you for your feedback! We're thrilled to hear that you’re happy with the lightweight design and performance of your battery. It's always exciting to see customers satisfied with their purchase. We hope it continues to power your adventures smoothly this spring and beyond! If you ever have any questions or need assistance, feel free to reach out. 😊

Excellent Value

Great value for the price. I’m happy with my purchase and will buy from WattCycle again.

false advertising

The battery arrived with the lid ajar. That wasn't good. The cells inside are 280 A cells, not 300 A. This isn't a 300 A battery as marked on the outside. I'd call that false advertising.

We sincerely apologize for the issue with the battery lid and the discrepancy in capacity labeling. As we stated on our website, this battery utilizes EVE LF280K cells (rated capacity 3.2V 280Ah, tested capacity 3.2V 310Ah). We can offer a $50/each refund and an automatic 2-year warranty extension. Please contact service@wattcycle.com asap if you not received the refund. We are taking steps to correct any labeling discrepancies and improve our quality control processes.

Great charger for lifepo batteries

I wish they had a 80 amp charger for faster charging.

Wattcycle 300ah

Love the batteries looking forward to getting more. Running these in a 48v system

Great battery

Been running 4 100ah batteries in my bass boat for almost 2 years and I’m on the water weekly. Zero issues and plenty of power for what I need.

Customer service

Awesome service quick response and easy to communicate with. I will definitely be doing business with WattCycle in the future

Thank you for your kind words! 😊 We’re so glad to hear you had a great experience with our customer service team. Providing quick and clear communication is always our priority.

Love the size of this battery for 300 Ah
Very heavy

Make sure to read the instructions first.

Long lasting and the range is unexpectedly good. Very efficient and this brand is of superior build. See You tube review of the take apart build of several brands. This Lifepo battery is tops and I can highly recommend them.

It is too early to rate the batteries. But from other experts, it does seem to do as promised. I will update in the future.

3 100ah batteries wired in series monitor only shows 100ah, not 300ah.

Hi, thanks for choosing WattCycle. Connect 3 batteries in series can not increase the capacity, it will in crease the voltage. Your new system is 36V 100AH (3 in series) If you connect them in parallel you will get 300AH.

Batteries are very good, but the monitor only recognized one battery as wired in series, saying 100ah when should show 300ah.

Fantastic price, charged right up using a 14.6v 20 amp AC-DC charger. Ready for use!

Very good product. Professional consumer support. Friendly, too.

Batteries arrived all at 13.2v packaged very well, even had a color instruction manual with all the specs and recommendations. their customer service is awesome they kept me with up to date tracking and quickly helped me with all my questions. I would definitely recommend

Compact 300 amp/hr lifepo battery.

Good quality

I was impressed with a YouTube review of this battery and have found it to be everything I expected. A glitch in their "service tips" section of their website led to a stream of phishing ads but when I brought it to their attention, they immediately corrected it. I am impressed with their customer response so far.

Thank you for sharing your experience and for bringing the website issue to our attention!
