What people say

Take screenshot of total order.

The supplier I ordered from sent my order to my son's workplace instead to my address. How they got his address I'll never know. Even showed my cc billing as his address. Said it was the address I used. Bull poop, I know my address. Said tough,you're problem. Be careful when ordering, take screenshot of everything. Can't do a 600 mile round trip so just canceled CC. Let them retrieve the batteries. Almost a $900 order. Beware. Yes was contacted by Wattcycle, not supplier. They never explained how they got my son's work address. I did not put it on the internet form I filled out and I my tax exemption does not apply in New Mexico. Yes they said they would send a pick up notice but I would have to pay shipping.

Hello, we have confirmed that the merchant placed the order and arranged shipment strictly according to the delivery address you provided, and we have also communicated with you by phone and email. Currently, we can generate a return label for you and return the battery that was mistakenly delivered to your son's work address; after we receive the returned item, we will resend it to your current residential address. Is this solution acceptable to you? Please feel free to let us know if you have any other suggestions.

Great price but one issue.

Great price and fast free shipping. The build quality is good. I ordered the Gen2 version which specifically claims to have Bluetooth and the Bluetooth symbol is on the case. However, bluetooth does not work. It's not my phone or the app. If you scan for bluetooth devices with any device, neither battery is detected.

Terrible customer service

Okay Batteries, Poor Customer Support

I purchased a WattCycle 314Ah mini that worked well for about 4 months. After a short period of being parked with no load, the battery suddenly reported 0% charge, would not hold energy, and was effectively unusable. All supporting components (solar, MPPT controller, fuses, wiring) were verified working. Customer support troubleshooting took multiple back and forth emails over weeks. Eventually, WattCycle agreed the battery was faulty and approved a replacement. Here’s where everything went bad: • I provided a specific shipping address for the replacement in writing. • WattCycle shipped the replacement to the wrong address anyway (the original order address, which was inaccessible to me). • No tracking number was provided in advance. • When I notified them of the mistake, support asked me to resolve it by contacting the carrier or refusing delivery. This was impossible. It had already been delivered. • Despite repeated, time-sensitive requests (and upcoming travel), WattCycle refused to send a corrected replacement or provide a prepaid label to reroute the battery. • I ultimately had to pay $170+ out of pocket to retrieve and ship the battery myself to fix their shipping error. The issue was slow communication, poor coordination, ignoring provided information, and shifting responsibility to the customer for their own mistake. I would not purchase from them again.

Hurtig levering til døren i Danmark.

Købte litiumbatterier. 3 dages leveringstid fra Polen til Danmark. Super service, kan kun anbefales. And an update on on the batteries: :-((((( 3 week old from Wattcycle-Europe and they have problems all the time. I thought you have fixed the parallel problem!! I have 2 - 12v 314A BT I parallel with busbars. Batteries are bought with one week apart and they have different firmware WT12_20004SW10_L447 and _L446, NO way to update firmware. The batteries behave strange under load. One show -1116 W other show -675 W during load at 1800 W. When loading ONE battery at the time they show 1800 W or 143,3A and 143,5A, almost the same. With small loads it is the same  I use "ExactMatch" mode and both batteries was fully charged before connection. The state of charge in % wary a lot when used for som time, one 85% and the other 63%. Or 100% and 85%. It differs a lot. It is always battery with firmware _L447 that show the lowest %. I have tried "Compatibility" with the same result. What do I do to fix thei problem? 3 week old from Wattcycle-Europe and they have problems all the time. I thought you have fixed the parallel problem!! I have 2 - 12v 314A BT I parallel with busbars.

Amazon has got a habit of sending more…

Amazon has got a habit of sending more than one order , something smile isn’t a problem but when the items cost $600 each and you ordered 4 and 8 are sent , returning items that weigh 50 lbs each , can really cause an headache . WattCycle did a good job , returning my money . I still 6 large lithium, solar batteries , I only wanted 4 . Thanks , for helping with the return . I’m happy.

Reply from WattCycle2025-11-15

We truly appreciate you taking the time to return the extra items. We understand the hassle involved and are happy we could resolve this smoothly for you. Enjoy your four batteries!

My battery arrived mostly dead & needed…

My battery arrived mostly dead & needed a full charge before use. This does not give me confidence that it will be reliable going forward.

Reply from WattCycle2025-11-15

We apologize for the concern this has caused. Like all lithium batteries, ours ship in a partial state of charge for safety. A full initial charge is required to activate and balance the cells, which is normal. We’re confident in its reliability, but our support team is ready to help if you have any further questions.

android app finicky but otherwise great product

Great product, good customer support. Price is not competitive, and android version of the app is finicky so 4 stars but otherwise great. The android app has trouble connecting after you connected to your battery and loose connection (walk away and come back). You have to wait for the connection to timeout before it can reconnect and it is annoying.

Reply from WattCycle2025-11-15

Thank you for your honest feedback. Our developers are actively working to improve the Android app's connectivity experience. We also continually evaluate our pricing to ensure fair value. Your satisfaction is important to us, and we hope to earn that fifth star in the future.

BMS PROBLEMS No address! No phone No.

I have two 12v, 12ah batteries in my small fold up mobility scooter running in series ( 24v ). The BMS trips out on a slight incline regularly. Usual bullshit, they want a photo! Queries go back to China. No phone number! Email only. Asked for an address to send them back. So far no reply except they want a "platform" No more replies. Ben Stocks

Reply from WattCycle2025-11-15

We sincerely apologize for the completely unacceptable communication and support experience you have received, and for the frustration the BMS tripping has caused with your mobility scooter. This is not the standard we wish to uphold. The request for a photo and the platform information is part of our standard troubleshooting procedure to document the issue and initiate a warranty claim, but the delay and lack of clarity you've faced are inexcusable. Please contact wattcyclepower @gmail.com if your problem not solved. Also check the spam or trash folder if not receive our email.

Is it scam?

I ordered (and paid ) a 100A battery 13th october. According to their website it is delivered between 1 and 5 days but today it is still in preparation. I sent them two emails (support and customer service) and no answer so far. Any explanation about the status of the order. Why?

Reply from WattCycle2025-11-15

We sincerely apologize for the significant delay in shipping your order and the complete lack of communication you have experienced. This is understandably frustrating and concerning, and we want to assure you that this is not a scam. There has been an unexpected delay in our warehouse processing, which has impacted a batch of orders, including yours. This, combined with a high volume of support requests, has led to an unacceptable delay in both fulfillment and our response to you. This is our responsibility, and we are truly sorry. Please contact wattcyclepower @gmail.com if your problem not solved. Also check the spam or trash folder if not receive our email.

NOT HAPPY!

Bought two 12v, 12ah batteries to run in series in a small 24v mobility scooter. Only 3 weeks old! The bms trips out on a small incline . After 5 minutes of use the charger measures 27 v on start up. Power diminishes rapidly. I was fully refunded for both batteries

Reply from WattCycle2025-11-15

We sincerely apologize for the frustration and inconvenience caused by the batteries in your mobility scooter. The symptoms you describe are not normal and indicate a serious fault. The rapid voltage rise and power drop you're experiencing are unacceptable, regardless of price. Your safety and satisfaction are our priority. We are issuing a full refund for your order. You do not need to return the batteries; please dispose of them responsibly at a local e-waste facility. A member of our support team will email you within the hour to confirm the refund has been processed. Please contact wattcyclepower @gmail.com if your problem not solved. Also check the spam or trash folder if not receive our email. Again, we are truly sorry for this experience.

The new 12v 314Ah smart mini batteries…

The new 12v 314Ah smart mini batteries seem to have a consistent problem with the BMS system. Well documented by numerous individuals now. My customer service experience has been horrible. Days between email responses, The one contact number is never answered. When they do respond to an email, I'm pretty sure they are using an English to mandarin back to English translation program. Something is lost in translation or they just dont care. Responses to questions or information sent are poor or incoherent. Instead of replacing or refunding their product malfunctioning battery, they keep asking for another test and proof of the results. Stall and delay. No way to speak with a rep. I can imagine why with customer service like this, and so many customer with the same issue. I suspect nobody on staff speaks English. I'll never buy from a non U.S. based company again.

Hesitant but now happy!

I was hesitant to write a review, since I was experiencing issues when I paralleled two 12V 314Ah LiFePO4 Battery with Bluetooth. I was seriously considering returning them, as I have a 5 month trip starting in a month. But once the issue was identified, WattCycle had a fix (beta) released within a couple of days. That beta app, with an option for Parallel Mode, resolved my issue immediately. It was a great relief that they acknowledge the problem, and quickly resolved. I cannot give them 5 stars, because I have not had the batteries long enough to really give anything but my initial thoughts. Now, WattCycle, needs to get this fix offered to us iOS people. I happen to have an android tablet that I only use for situations like this, but a general release on iOS would be greatly appreciated.

Reply from WattCycle2025-09-24

Hi Jeff, We sincerely appreciate you giving us the opportunity to resolve the parallel battery issue. Thank you for your patience as we rolled out the beta app fix—and for your understanding as we work to release the iOS version. Please join our newsletter and we’ll keep you posted on its progress. Safe travels on your upcoming trip! Best regards, The WattCycle Team

Customer service nonexistent - Facebook to the rescue

Ordered and paid for 4 100 AH batteries (over $700) and received only 1, with an email saying that completes my order. Customer service phone does not answer. Chat is a bot and when it says it is escalating to a person, no person comes on. Have sent emails but so far no response. Company is apparently not properly staffed to fill orders. accurately nor to fix problems when they occur. Will do credit card chargeback, I guess. Update: I finally reached someone by sending a Facebook Instant Messenger message to their Facebook account. The person who responded was able to get the customer service team to answer my emails. They agreed to send the 3 missing batteries on condition I close the credit card dispute. I did that and they sent a tracking number and an apology. Upgrading my star rating to 2 stars as a result.

Reply from WattCycle2025-09-24

Hi James, We are very sorry to hear about your incomplete order and the frustration it has caused. This is not the experience we want for any customer. We are investigating this matter and we have sent you the tracking number to ensure you receive the remaining three batteries without further delay. Thank you for bringing this to our attention. Best, The WattCycle Team

Great support

I have bought a couple mini batteries from Wattcycle and another one from a different brand. The first has had no issues and I am 100% satisfied with it and prefer it over the other brand. The second had a “hung BMS” after about a month and it stopped all input and output. I contacted support and they were quick to offer replacement rather than to try to fix the issue, which I appreciated. They offered some helpful suggestions but those didn’t help. They quickly sent a replacement.

Reply from WattCycle2025-09-24

Hi Mike, Thank you for trusting us again. We're happy that the first battery has served you well, and we apologize for the issue with the second. Our team is committed to making things right quickly. We're glad the replacement process was smooth, and we stand behind our products. Best regards, The WattCycle Team

Good product and it arrived on…

Good product and it arrived on schedule. The only issue I have is that it takes almost a week each time I contact them to get a response back. I tried to stop one order immediately after placing it because I made a mistake. By the time I received a response, it was too late because the order had been shipped. I would have had to pay to ship it back, so I just decided to keep it.

Reply from WattCycle2025-09-24

Hi Stephen, We sincerely apologize for the delayed response that affected your order modification request. We are actively working to improve our response times to ensure such situations are avoided in the future. We appreciate your understanding and are glad you're satisfied with the product itself. Best regards, The WattCycle Team

I can't get product support

I can't get product support. I have a misbehaving BMS. I registered for the warranty, and have tried to contact customer service, and have gotten no response besides an automated email with no contact or troubleshooting or warranty info. The battery won't charge (unless I take the SOC to 0% then "wake up" the BMS with a jump from a 12V battery. none of my expensive and fully functional LiFePO4 chargers can charge it from anything except 0% SOC)

Reply from WattCycle2025-09-24

Hi Nate, We are very sorry for the unacceptable delay and lack of effective support. This is not the experience we want for any customer. To resolve this immediately, please email to [email protected] to gather your details. Our technical lead will contact you directly within 24 hours to diagnose the BMS issue and arrange a replacement if needed. Thank you for your patience. Best regards, The WattCycle Team

Bluetooth is Useless-So is your return policy

The first battery I bought is excellent. You were getting great reviews by a lot of people. This Bluetooth mini 12v 100ah is useless to me. When I saw this first on YouTube it showed a very good app that showed the amount of charge in each cell. The one I just received, all the Bluetooth did was show the amount of charge in the battery; whether it is charging or discharging. I thought this would be like the app shown on the YouTube video but sadly it is not. So, as it does not Fit my application, and with a 30 day return policy, I requested a return that was denied. You were going to charge me almost the price of the battery to return it. So now I’m stuck with a battery I hate and can’t use. Now, I’ll buy a Victron Shunt to see what’s going on with my batteries. Thanks for nothing.

Reply from WattCycle2025-09-24

Hi Susan, We sincerely apologize for the frustration caused by the difference between your expectations and the product's actual Bluetooth features. We are sorry to hear about your return experience. Please email to [email protected] with your specific needs better and explore a satisfactory solution for you. We are also reviewing our return policy communication to ensure greater clarity.
