Safety First. Improvements Always.

WattCycle was built for people who rely on power—RVers, off-grid builders, and home backup users. We pay close attention to what the community is discussing (especially around safety and real-world behavior), and we turn feedback into engineering actions—then validate changes before release.

Q1: Will the 12V 314Ah have the same safety concerns people have seen with some other brands?

Recently, YouTube has been buzzing about safety concerns related to thermal management in a certain brand's products. That’s why our 12V 314Ah includes built-in aluminum cooling fins (up to 30% faster heat dissipation) plus oxygen-free braided copper conductors for efficient current flow and steadier performance under load.

Q2: Parallel batteries can be tricky—what have you done to improve this?

You’re right: many lithium battery brands run into parallel behavior quirks in real-world setups. We listened to what users were experiencing and introduced a Parallel Mode option to help manage parallel operation more smoothly.Additionally, on Bluetooth models, you can control the battery on/off through the app, giving you more control over your system—especially when managing multiple batteries.

Q3: What have you done about parallel-system usability on Bluetooth models? 

We released an app update that includes a new Parallel Mode with two selectable options: ExactMatch Mode (same-brand packs) and Compatibility Mode (mixed-brand). Click here →

Q4: Why launch the 48V 100Ah server rack battery V2 version? What’s different from V1?

After Will Prowse tested our V1 rack battery, we took the feedback seriously and went back to refine the platform. V2 is the result—focused on improved long-term consistency and a better overall ownership experience.

Q5: How do you verify products before launch?

To protect customer experience and the WattCycle name, we don’t release products lightly. Before any model goes live, we run checks such as thermal testing, load testing, and other validation steps to confirm expected behavior.We also share more behind-the-scenes updates on our YouTube—and we genuinely appreciate every customer and creator who brings constructive feedback. It’s how we keep iterating and improving.

Q6: What does the 7-year warranty mean?

We offer a 5+2 year warranty structure as published for these platforms—our way of standing behind the quality we’re shipping.
