Great Batteries!Great product!
Very happy with our WattCycle batteries. Called on to provide power for a inverter that keeps our pellet stove functioning during the ever increasing grid disruptions! Ha ha... Says in form, date of experience. On going! These were a gift to my son. Might be one of the most useful gift we have given him!

Had my two 12v314Ah batteries since November. Been very happy with them. I emailed customer service and they got back to me in a day or so and resolved the issue in the app. I think it was an app update that bumped them out of parallel. Simple fix.

Justine was my contact for a question I had before purchasing a 314ah smart battery. She quickly responded to my inquiry and even provided me with additional information to guide me in my purchase. Great job from Justine and I am happy with my third Watt Cycle battery purchase.

High-Capacity 314Ah Lithium Upgrade for My RV – Excellent Customer Support
I recently purchased two WattCycle 12V 314Ah Lithium Batteries with Bluetooth for my RV (travel trailer) setup and have been really impressed so far.The batteries feel solid and well-built, and the capacity is exactly what I needed. In a travel trailer, weight is an important factor, and these are a big upgrade over traditional lead-acid options. I’m running them in a setup with Renogy components (solar + DC-DC + shunt), and everything integrates smoothly.The Bluetooth functionality is definitely worth it. Being able to monitor the batteries and control charge and discharge on/off directly from the app is a really useful feature, especially when dialing in a full system. I’d absolutely recommend going for the Bluetooth-enabled version.What stood out even more was the customer service. I ran into a delivery issue with the original shipment, and the WattCycle team handled it quickly and professionally by sending out replacements without hassle. That level of support makes a big difference for a purchase at this level.Overall, the product delivers on performance and usability, and the company comes across as focused on making high-capacity lithium batteries more accessible without cutting corners. Very happy with the purchase and would recommend.

Some of the best customer service ever
Some of the best customer service I’ve ever experienced. Had a few questions over several orders and have always received a reply (usually 25-36 hours due to time zone differences) that resolved my question or concern. WattCycle is a fantastic company. Very happy that I found them and as I mentioned, I’ve made several orders already. I have a fourth order planned.

Capacity as advertised.
Batteries are great. I checked capacity on all four and they were perfect. Wattcycle did not have the charger promised, and refunded me $100. I am 100 percent happy with this purchase so far. I will be using these batteries soon when I am camping.

Wattcycle experience …
I had questions and Wattcycle responded in a timely manner. I purchased 2-200ah batteries for an insulated trailer tool box. I wished they had a 2 smart 314ah batteries that would fit my tool box, but the ones I purchased will work. I guess my next purchase will be one of their battery monitoring unit, unless they want to review one for them??? Thanks Wattcycle

Off to a great start with my WattCycle
12v 314AH batteries. They arrived timely in excellent condition due to solid packaging. Really look like good quality in person. The App has been helpful in monitoring their status upon arrival and during initial charging. I look forward to installing them soon in my boat to provide us backup power for our refrigerator. I reached out to WC on the website to confirm my warrant registration and did get an quick response with the confirmation information I wanted. Thanks WC for excellent service!
