We released a walkthrough video showcasing how seamlessly the Edge Vanworks 600 Ah lithium kit can replace the old KS2 batteries in Roadtrek and Hymer vans seamlessly. Not only is it reliable, it is a relatively easy DIY. The video below shows how to install the batteries.
Key highlights include:
- Epoch LiFePO₄ batteries are wired into the existing KS2 communications bus, meaning the van’s original monitoring and control systems stay fully functional—without needing those unreliable and expensive KS2-branded batteries. Edge Vanworkds is one of the only shops in the country that maintain the KS2 Ecotrek battery disconnects in Roadtreks and Hymers. (Ecotrek switches or Firefly Controllers).
- The new setup offers significantly higher capacity (600 Ah vs original), is more affordable, and includes an impressive 11-year warranty via Epoch.
- Users gain additional telemetry, like real-time battery life data, charge rates, and system diagnostics—providing clearer insight into their power systems.
- The installation is user-friendly, cleanly integrating into the existing van framework, preserving the factory look and functionality. This maintains the additional weatherproofing and battery protection from the metal boxes.
