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.

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.

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 →

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.

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.

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