Battery and shipping were amazing. Used it with 2 106sv and my live scope for 2 days fishing this weekend and still have 99% battery left. Only bad thing is that it went on sale cheaper a week after I bought it.

Thank you for your positive review! We're so glad to hear that the battery and shipping experience were amazing, and that it's performing exceptionally well with your LiveScope setup—lasting two full days of fishing is impressive!
We also appreciate you mentioning the pricing. We understand that noticing a sale shortly after a purchase can be disappointing. Our prices do fluctuate based on various promotions, but we always strive to offer great value. We hope you continue to enjoy the outstanding performance and reliability of the battery for many future fishing trips!
Poor customer support takes 2 days by email to get a response,device does not work any inverter i purchased. I returned 2 before testing on another battery and it works fine on my 100ah battery in my camper. Assistance,swap or return ill be fine with. I'll let you know how it goes fellow review readers

We sincerely apologize for the delayed response and your inverter issues. This falls short of our service standards. Thank you for testing with your camper battery—we’ll investigate the compatibility concern. Your patience is appreciated.
I bought the (Father's day sale) pictured in Facebook, 2 100ah 12v batteries (group24) and a charger after corresponding by email I bought 2 specials thinking I was purchasing 4 batteries and 2 chargers 613$. Wrong, not having read the contract fine print I received 2 batteries and 2 12v chargers of no value to me. False advertising. And refusal to make amends. Disreputable.

We regret the confusion around the Father’s Day promotion. We’ve since clarified the wording to avoid future misunderstandings. We value your trust.

Even though the company says they are working diligently on the app the app still does NOT connect to Bluetooth or show any signs of life. This is the main reason for buying their batteries. I bought six.
False advertising if you ask me. Very disappointed.

I of 4 100AH Pro batteries that I bought has quit. I have been trying for about 2 weeks to get a answer from Wattcycle. I sent a video described the problem. They said that the video was to large. so they said to to send a email with problem and serial number. I did that and still waiting for an answer about this.

Ordered 9 days ago and still haven't received any batteries. I have currently had to delay my fishing trip by 3 days waiting for them. Not happy

I purchased a Watt Cycle 12 V 100AH LIFEPO4 on Temu, which was supposed to be new... sold and shipped by the "manufacturer" Watt Cycle Industrial Revolution... which has a total internal series resistance of 12,258/59 mΩ!!! (measurement taken as soon as the Battery was received by the courier), I have videos and photos of the measurements!
The seller says that such a high resistance is normal! Only SCAMMERS COULD CLAIM SUCH AN IDIOCY!
I have two perfectly calibrated internal resistance testers (FNIRSI HRM-10 and RC3563), which give essentially the same result
The internal resistance provides a real indication of the aging of a battery (cells).
The internal resistance represents the limiting factor of the battery to deliver the required current and/or provide the necessary energy, then leads to greater heat generation in the battery under load, with consequent loss of unwanted energy.
If I disassembled (hypothesis) the WATT CYCLE battery pack (which has, I remember, a total internal series resistance of 12,258/59 mΩ !!!) bypassing the bms and measuring the 4 cells directly on the terminals, which to be new grade A should have an internal resistance per cell ranging from 0.18 to 0.22 mΩ, what resistance would I detect on each single cell? VERY HIGH, obviously.
The excuse cannot be the probes (or clips) that do not make contact correctly, or the surface finish of the terminals in contact with the probes, terminals and threads have been cleaned previously, the results are those!
Obviously the WATT CYCLE has been
compared with another battery with the same characteristics and similar load (Eco Worthy 12V 100AH). The WATT CYCLE does not go beyond a certain charge threshold, and lasts half as long as the aforementioned Eco Worthy (12v 100AH BM) which has an internal resistance of less than 3mΩ) that I have had for a year and a half!
Untrustworthy seller and scam products!
Reply from WattCycle2025-04-08
We understand your concern about the internal resistance measurement of your WattCycle 12V 100Ah LiFePO4 battery. We take these matters seriously. While a slightly higher resistance can occur due to various factors, including temperature and battery state of charge, the value you've measured is indeed higher than typical. We want to investigate this thoroughly. Please contact our customer support team immediately with your order details, photos, and videos of the measurements. We will work with you to diagnose the issue and provide a suitable resolution, which may include a replacement battery if necessary. We are committed to ensuring our customers receive high-quality products and stand behind our warranty. We want to understand what happened with your battery and make things right.
I placed my order for a battery, charger and a master cut off switch. I received the battery and charger but not my switch… I keep trying to check but it says order delivered.
Reply from WattCycle2025-04-23
We apologize for the incomplete order. Your orders are shipped out in different packages, and the battery switch is out of stock, so the delivery will be delayed. All your orders have arrived. Thanks for your understanding.
I purchased the 300-amp battery through Amazon. The top kept coming off and the battery was eventually dead and would not recharge. I contacted customer service, and they sent me a label to return the 300-amp battery. I asked for the 280-amp battery with the correct label. They sent me the 300-amp battery again with a 250-amp fuse. I don't know if this the same battery or a new one. And I did not get the 280-amp battery like I requested. Meanwhile, I see $50 refunds on social media and $20 discounts if getting a 300-amp battery. None of these discounts or refunds were offered to me. Why were the refunds or discounts not offered to me? I have paid the same money for a falsely advertised 300-amp battery still in my possession. I would not recommend your company to anyone and feel I need to express this on Will's YouTube site where he reviewed your battery, but I have not hoping for some type of financial resolution by completing this survey.

Dear Alan,
We deeply regret the multiple frustrations you've experienced. We have proceed the refund once we got your message. And we're auditing our Amazon fulfillment process to prevent recurrences. Thanks for your understanding.
I ordered the 300ah mini based on a YouTube review by Will Prowse. It arrived in good condition and I fully charged it and then put it to use in my off grid solar setup. Just a few days later I got a $50 refund from Watt cycle because Will notified them that their 300ah battery only tested to 280ah - the capacity marked on the Eve cells. That was good of them.
A few weeks later I got a phone call from a very nice and polite young woman from China just to see how my battery was working out. Then she asked if I would write a review on their website. I said I would.
I spent over an hour writing an honest review. After it was submitted I got a thank you email and a discount code towards my next purchase. I checked online later but did not see my review posted on their website so I emailed them and asked what was the matter with my review.
They asked me to send them a copy of my review and I told them I couldn't because I wrote it on the website and had no copy. Then they asked me to post another review and include pictures and they would give me a $50 credit towards another battery.
To be honest, I was insulted. I had written a very good review already and they may have thrown it out because I mentioned the false advertising and Will Prowse or they just plain lost it. They couldn't just be honest and admit it. I wasn't going to bow down to their $50 bribe for a five star review.
So at that time I had another 280ah battery in my Wattcycle cart ready to buy but I just didn't feel good about Wattcycle. Their product was good but the customer service was really not commensurate with their products.
I ordered another 280ah big battery from Eco Worthy for the same price of the Watt cycle 280ah battery with the $50 discount. It got an even better review from Will Prowse.
What Watt cycle did well was man up and offer a refund when they were caught selling their 280ah battery as a 300ah one. That was the right thing to do. And to actually have a very nice customer service person from China call me was impressive... She spoke English very well. They just couldn't admit that they didn't like my review I posted or just plain deleted it by accident if that was what happened.

Dear Sanjisdad,
Thank you for taking the time to share your feedback and for choosing WattCycle. We truly value your input and see it as an opportunity to improve. We’d like to address your concerns and clarify the steps we’re taking to ensure a better experience for you and all our customers.
Regarding Battery Capacity Labeling
We completely understand your disappointment with the battery capacity labeling. As you mentioned, after Will Prowse’s review, we immediately reached out to all affected customers and proactively issued refunds because we believe honesty and transparency are the foundation of customer trust. We have since updated our product pages to ensure all specifications accurately reflect real-world test results. This incident has reminded us that accuracy in product information must always take precedence over marketing needs.
Regarding the Unpublished Review
We deeply regret that your review was not published and upon review, we found that your comment failed to submit due to a system error (not a manual deletion). We have since fixed this issue.
Apology for Miscommunication: The customer service team’s suggestion to “provide photos for a credit” was intended to encourage more users to share their experiences, but it was never meant to imply “positive reviews for rewards.” We have retrained the team to avoid similar misunderstandings in the future.
Your experience has shown us that even with excellent product performance, oversights in service details can undermine the customer experience. You’re welcome to contact me directly at [email protected] anytime. We’re committed to proving our dedication through actions, not just words.
Thank you again for your honesty and understanding.
Best regards,
The WattCycle Team
Purchased the battery from temu April 26 2024 lasted till September 2024 will not charge
Reply from WattCycle2024-12-23
I'm sorry to hear that the battery you purchased from Temu stopped working after just a few months. That's definitely not ideal. Please contact our Temu store or [email protected] asap. We will start the after-sale process for you.
Battery is as expected, fast charging a d good power. Company communications could be better, showed shipped 3 days before FedEx had the package. Not wmWattcycle but FedEx changed the delivery dates twice before completing delivery. All in all good company to deal with, I have only been using the battery for a couple of day with no.issues

We're glad to hear you're having no issues with the battery and are here to support you if any questions arise. Thanks again for choosing WattCycle!
Have only charged them so far. I am planning on using them in a home made camper using 4 200W bifacial panels for charging.
Contact me in a year and I will let you know how they worked out
Reply from WattCycle2024-11-12

I just tried to buy from wattcycle from Ireland using my paypal which i have never had an issue with in 20 years. Wattcycles checkout simply did not work for me, as first i get a message twice from PayPal saying "PayPal unavailable please try another payment method" which made me suspicious, after 3 attempts in moved to the checkout page which only showed delivery options for USA or Mexico!? then when i try to contact them via the "contact us" button, it goes to a stupid Chapca verify which simply does not work, choose the animal or choose the number of animals, etc etc. well by this time your in no mood to buy anything and cant even contact them thank to this, so i gave up and put my miserable experience here. Thank goodness for Trustpilot!
OK So after the wattcycle "reply" i try the "EU" site and after 2 attempts i somehow manage to get a battery delivered.? So tonight i decided to buy another and OH DEAR, here we go again the checkout just goes around in maddening circles, 6 attempts to simply checkout with paypal! presenting the same filling the address after clicking on paypal. using paypal should need no further filling in after you try to checkout, so another sale lost and probably all future sales now due to this stupid glitch?
