A few consumers mentioned that specific technical components required additional troubleshooting, careful adjustments, or separate shipping arrangements upon initial arrival at their homes.
I had an issue with my battery not wanting to take a charge.
I reached out to support and Erin helped me get a replacement out very quickly.
Erin was quick to respond, offered clear guidance and made getting a replacement unit hassle-free.
I will buy my next battery from this company.
A+

I purchased two WattCycle batteries and initially had an issue getting the BMS to activate. Talia provided excellent support throughout the entire troubleshooting process, stayed in contact with me, coordinated with the technical team, and helped us find a solution.
Both batteries are now working properly, charging to 100%, and we have successfully tested our backup power system during a power outage.
I especially appreciate Talia’s patience, follow-up, and willingness to help us resolve the issue. Thank you, Talia, for the excellent customer service!

I received the new 6500 inverter in a timely manner and it was simple to install connected it to my wattcycle 5120 100ah server rack battery and to my jinko 390 panels and it works perfectly. Wish you could send some more free products to test for you.

I had a technical problem with my WattCycle battery. The customer service team was excellent—they replied to my email almost immediately and walked me through the troubleshooting steps. Even though the battery was ultimately defective, they handled it professionally and sent me a replacement very quickly. I am very satisfied with how they handled the situation.

I received a 48v 100Ah wall mount battery and the cell voltages were not properly balanced. Wattcycle reviewed images of the battery display and determined that the BMS was not working properly. Erin helped me with the problem and they quickly sent me a replacement battery. Sometimes components don’t function as intended, and great customer service is how those problems get resolved properly. Thanks Erin and the entire Wattcycle team for taking care of my issue. Well done!

Battery failed - replaced for free - BUT ZERO phone support!
Initial purchase, delivery, and unpacking went well. Documentation covered the basics, but zero explanation of the heavily promoted "Super 4-in-1 switch", which only has two positions, neither of which are labeled. The switch itself appears identical to many other switches of this type that contain an integral LED light which indicates On or Off, but this one has no LED - also confusing. Battery charged up normally - but the first time using it (professionally installed marine application), it failed and would only deliver between 8 and 11 volts. Tried to reset it using the Wattcycle app, but app was frozen at 88% SOC. The app also has little documentation. What followed was a long series of unanswered phone calls to the U.S.-based phone number in Georgia, which NEVER gets answered by anything other than an answering machine. Instead, you leave a message and then receive email "support" from a "Customer Service agent" (not a technician) the following day (Beijing time.) Spoiler Alert: There is ZERO U.S.-based Technical Support for this product! The US. phone number is a ruse, plain and simple.
After multiple requests to have a TECHNICAL support person CALL me, I finally received a call from China, only to find out I was speaking NOT to Tech Support but to another "Customer Service" agent! When I asked her to connect me to tech support, she said none of their engineers speak English, so that wasn't possible.
Eventually Wattcycle emailed me instructions on how to unfreeze the app and reset the battery, and it appeared to recover. However the SOC never stabilized at 100%, and continued to wander as low as 92% for no apparent reason. Further, the Customer Support person could never adequately explain what caused the initial failure, or instill any confidence that it would not occur again. Eventually they offered to replace the battery, shipped me a new one, and provided a free return shipping label to return the original battery. It's only been two days but so far it appears to charge normally and maintain SOC while under float.
The email communications during this period were all very polite, understanding, and professional. Unfortunately, they were unable to communicate cause and effect issues on a technical level - because they're not trained in technical support! Instead, they apparently translate the emails to and from the engineers, and then relay the responses. The results are predictably unhelpful and frustrating. I received instructions on how to estimate SOC, based on battery voltage (on a LiFePO4 battery!) and other such nonsense in an attempt to explain the issue. Also instructions on how to adjust timing for "BMS Sleep mode", which there is absolutely NO setting for in the app. Also failed to address how to disable "Sleep mode", which is absolutely useless and unnecessary on a boat that is continuously connected to shorepower with a properly programmed LiFePO4 charger.
All of this back and forth occurs over email with a 15 Hr. time difference delay. By comparison, Epoch support answered my call on a different boat issue, and within 5 minutes I was speaking to a U.S. tech person with installer experience who could instantly understand the issue and provide specific and credible solutions. Night & day difference.
This battery got great reviews from a construction and value basis, and my replacement battery may turn out to be trouble-free - way too early to tell. Regardless, I cannot recommend this product until Wattcycle commits to providing well-trained, English-speaking TELEPHONE tech support available during normal US business hours. Trying to resolve problems the way they operate now is just mind-numbingly frustrating.

First of all, thank you very much for your valuable suggestion! We truly appreciate your feedback, and we will also pass your request along to our team. We completely agree that multilingual support is an important feature and something we definitely need to improve.
Please give us a little time as our customer service and technical teams continue to grow and improve. We’re working hard to provide a better experience for our customers, and we hope you’ll look forward to the improvements and updates ahead. Thank you again for your patience and support! ❤️
Talia was a pleasure to deal with.
There was much back and forth communication for the process of trouble shooting. All of these discussions were polite, informative and dine in a timely matter.
In the end the battery had to be replaced and Wattcycle upheld their warranty as advertised.
Cheers!

I recently purchased a WattCycle 314 Ah LiFePO4 battery and have been testing it extensively in my caravan.
So far, I am very impressed with both the battery and WattCycle's customer service.
I have tested the battery under continuous loads of approximately 25–30 A, as well as under much higher loads of up to around 100 A. During the capacity test at 25–30 A, I managed to get approximately 326 Ah out of the battery before stopping the test, with the battery still having a small amount of capacity remaining.
I have also closely monitored the individual cell voltages during both charging and discharging, including under high loads. The cell balance has performed very well, even when the battery was subjected to currents approaching 100 A.
My system uses Victron equipment, including a Victron SmartShunt, MPPT 100/30 and IP22 20 A charger, together with approximately 320 W of solar panels.
What I particularly appreciate is WattCycle's customer service. They have been helpful, patient and willing to discuss the technical details. When I had questions about the battery and BMS behaviour, they took the time to help rather than simply giving a standard answer.
I have only had the battery for a relatively short time, so this is not a long-term review yet. However, based on my testing so far, the battery has exceeded my expectations.
Excellent capacity, very good performance under high loads, and excellent customer support.
I am looking forward to continuing to test the battery in real-world use.

I received great customer service from Talia. She was timely and very responsive to the emails I sent. I didn't expect to receive any communication over the weekend. She was thoughtful and considerate of my needs. She not only gave me a solution but she made things better. I really appreciated her and the way she handle my concerns. This is the customer service that makes the company as reputable as it is.

I am happy with my product and the service. Special thanks to Mihel for the clear and fast communication.
I ordered the 48volt server rack battery to integrate in an off grid setup. When testing wraps up I am definitely considering expanding the system with more of these battery's. Even the neighbor is asking to build a duplicate system.

Multiple emails with Talia about whether WattLink cable was compatible with my EcoFlow Delta Pro 3. Turned out it is not and new cable in development. Talia was prompt and provided accurate information. Also, noted I had placed an order for another product and confirmed its shipping. Very happy with this service.
