Reviewers overwhelmingly had a great experience with this company. Customers frequently praise the exceptionally helpful staff and outstanding support team for resolving issues with remarkable speed, kindness, and constant professional care. People also highlight that the items delivered are remarkably high quality, highly reliable, and perform wonderfully across diverse household setups and outdoor adventures.
However, some customers also noted minor inconveniences regarding slower daily email communication, delayed responses, and occasional product compatibility or inverter display challenges. A few consumers mentioned that specific technical components required additional troubleshooting, careful adjustments, or separate shipping arrangements upon initial arrival at their homes.
Excellent warranty support & hassle-free battery replacement after 2 years!
I purchased a Wattcycle 12V LiFePO4 battery two years ago. Recently, the battery stopped charging and showed a very low voltage. I contacted customer service and was assisted by Lyra.
The communication was outstanding right from the start. Lyra provided clear troubleshooting steps, and once we verified that the battery was faulty, they immediately arranged a warranty replacement. I returned the defective unit with the provided shipping label, and a brand-new replacement battery was delivered via DPD in perfect condition.
It is rare to see a company stand behind its products so responsibly, especially after two years of use. Huge thanks to Lyra for the fast, helpful, and professional support! I highly recommend Wattcycle to anyone looking for reliable products and top-tier customer care.

Unfortunately, I had a problem with one of my two 12V 100Ah smart batteries. My support request was handled quickly and professionally. I received return labels to send the defective battery back free of charge, and a new battery arrived shortly after. The service team at Watt Cycle provided friendly, prompt, and accurate communication. Based on my experience, I recommend this brand.

Great customer service; prompt delivery; great products; would buy again
I've received prompt guidance on charger and battery combinations for existing products we already had (purchased by others) where there was no real obligation.
We purchased a number of batteries some time later, which where promptly delivered. Unfortunately one was faulty, but the customer service has been great, and it was replaced immediately.

Mihel has been very helpful as I expanded my house battery Bank from 2X 314Ah to three by the 314Ah. My major concern right now is that the wattyycle monitoring app seems to show and inconsistent battery state of charge for all of my batteries. I'm not sure what to believe when I look at the app..
WattCycle 回复2026-08-12
Thanks for your feedback.Here is the situation: we recommend that the customer fully charges the batteries before connecting them in parallel. Although parallel connection eventually equalizes the voltages, the voltage characteristics of these lithium batteries mean that voltage levels remain similar across the 20%–80% State of Charge (SOC) range, which can make SOC readings appear inaccurate. Fully charging each battery will resolve this issue.
I was having trouble with one of my 4 314 ah reading the app showing 0. Contacted Wattscycle and after steps to wake up the BMS Mihel shipped a replacement. Thank-you for great service.

we were happy with our batteries until one stopped responding. Although it was a bit slow to communicate through texting with watt cycle we would have preferred a phone call, they did take car of our requests. We would have preferred quicker responses. We are now waiting for a new battery under warranty.

Thank you for the review! ⭐️ We truly appreciate your understanding and support.
When handling certain technical issues, our customer service team often consults our technical experts to ensure we provide you with accurate and reliable solutions. Consequently, email communication can sometimes be more efficient than phone calls, as it allows us to organize and verify technical details more effectively.
Of course, if you would prefer to communicate by phone, we are more than happy to accommodate that. 😊 Thank you again for your understanding, patience, and support!
I wanted to wait to rate the product until I had a few months experience with it. As far as delivering power and recharging reliably, I haven't had a single issue. As far as the utility interfaces, I still find portions of the app unintuitive/unwieldy (e.g., the meaning and use of the charging and discharging "buttons," and the occasional error screen with nothing but Chinese type on it). I also find the Bluetooth to be very underpowered compared to other systems in my RV (the app will connect only from the room immediately adjacent to the battery).The customer service people are nice, but don't always understand your questions or may give unhelpful answers. But ask me if I would buy another one of these and right now I'd have to say yes.

Thank you very much for your suggestions! We have passed your feedback on to our engineering team. We also greatly appreciate the professional insights you’ve shared. We will continue to optimize and iterate on our app to constantly improve the user experience. Thank you again for your support!
So far it's been an OK battery, but it seems to really sag when I start drawing any current from it - it's alright, I guess, but I don't feel very comfortable drawing more than a dozen amps. Also, I gave a 3 star review, and I realize that voltage does drop during discharge - one doesn't need a typical set of chromosomes to accept this as a fact of life... but what's too complicated for the AI responder bot to know about is the concept of less than desirable internal resistance, which seems to be the case with my current Wattcycle battery. In other words, terminal voltage drops when there's a large current draw and rebounds when the demand is withdrawn. It's not a deal breaker, but it's just at the edge of what I can tolerate. After all, that voltage drop is going into heat SOMEWHERE in the system.

Thank you so much for your 5-star review and support! We truly appreciate your trust and recognition.
We would also like to clarify that it is normal for the battery voltage to gradually decrease during the discharge process as the stored energy is being used. This is a natural characteristic of battery operation and does not indicate a problem with the battery.
Thank you again for your support. We are always here if you need any assistance!
Really hate I wasted my money on this battery…It doesn’t connect to Bluetooth..

Your appreciation means a lot to us. Our developers are continuously optimizing and upgrading the app to enhance its features and user experience, ensuring you enjoy an even better experience.
Stay tuned for future updates! Please feel free to share any suggestions or ideas you may have. Thank you again for your support!
The battery works fine but I could have used more information with the Bluetooth app. I had to search online for a few answers that I thought should have been included in the documentation.
Also, the Bluetooth signal seems weak. I can't connect unless I am within about 8' of the battery.
WattCycle 回复2026-08-04
Thank you very much for the five-star review!
We appreciate your recognition of our products and services, and we are delighted that you are pleased with your purchase.
Regarding the Bluetooth function, the signal can be affected by the connection distance and surrounding obstacles. If the device is too far away, or if there are obstructions such as walls or metal objects in between, your phone may fail to detect the device or experience an unstable connection. For the best Bluetooth experience, we recommend staying close to the battery and connecting in an unobstructed area.
If you encounter any issues while using the product, please feel free to contact us at any time; we are here to help.
Thank you again for your support, and we wish you all the best!
I had a ridiculous transaction with WattCycle. They listed a low price for a set of 4 battery cells. When they sent me a fully integrated 12 Volt battery I tried to return it. Instead of accepting the return, they told me to merely "open" the battery to retrieve the cells I bought. Stupid. But I have tools and cut open the battery to find cells that didn't match the description on the listing. I couldn't even use them. They dragged me through a protracted argument which lasted months before they finally arranged for a return and refund. I'll never try them again even though there's a good chance this was a perfect storm of misunderstanding and incompetence shielded by AI agents manning the customer service desk.

as of today still problem not solved and they have my money.i hope after this review someone reaches out to me
After reading this review, someone did contact me and finally the ball got moving after another week. I finally received an email with a tracking number and they sent a replacement battery out. They did make good in the end. They need to do a lot of improving on answering telephones and responding to emails. That is the only means of communication they have because no one picks her phone up in the end they resolved the problem and I was happy and thankful for that.

Not sure yet about the longevity of the product, but customer service is awesome.
This was my first time buying a WattCycle product and my first time dealing with their customer service. For the product, I am mostly happy with it. I bought the 314ah mini version to be used as the house battery in our camper van. It ran flawlessly at first but unfortunately it died on us without warning after one year. That said, the customer service has been awesome to deal with. They proposed different things to try to revive the battery, and when it didn't work, they offered to send a replacement, and even prepared a return label for me. So a solid 5 stars for their after-sale support, and 3 stars for the actual product. I will update the product score if everything goes well with the replacement.

Will leave the above, but, need also to complete with the continuing of the case.
I contacted customer support and received a rather quick answer, although a bit confusing, so I did misunderstod how to return the wrong battery.
Once cleared out and all fixed, I did receive the correct battery within 10 days from complain and the wrong one was returned as well.
