Hymer / Roadtrek KS2 Ecotrek Batteries failures have a solution that is MORE affordable than the stock KS2 Battery replacement. It is also leaps and bounds the best option with an 11 year battery and many more features that can be found below.
Our DIY kit is a Epoch Batteries 600ah replacement to the 400ah KS2 battery system (or 1200 instead of the 800ah systems), but we offer a variety of solutions in house from 600 to 1360ah).
Our founder, Gordon White, spent years understanding the quirks and common failure points of the Ecotrek electrical systems. His solution? Replace the underperforming stock batteries with Epoch 300Ah lithium batteries — a smarter, safer, and more powerful upgrade.
Even if your original batteries are still working, upgrading can transform how you use your van:
If only one KS2 battery has failed, it may be more cost-effective to replace it — but if both are failing or you want more capability, a full upgrade with Epoch lithium is the clear choice.
We don’t just replace your batteries — we upgrade your entire experience while keeping your RV’s electrical system working exactly as the manufacturer intended (or better). We rebuild the KS2 battery boxes and replace the cells with Epoch batteries a top of the line LiFePo4 cell at middle of the road pricing. Roadtreks and Hymers love Epoch batteries, if the ks2 communications are rewired correctly!
We replace the KS2 system with 600Ah of Epoch lithium power — all in the same space. No janky wiring, no guesswork.
Every battery includes a smart Battery Management System to protect from overcharging or over-discharge — no babysitting required.
We maintain compatibility with your inverter, converter, and dashboard systems. You keep all the original features — and gain more power and visibility.
For added safety, we can install marine-grade isolation switches to fully disconnect your batteries from the RV system — a unique safety feature rarely offered elsewhere.
Whether you’re running existing panels or adding new ones, our battery systems can store and use solar energy more efficiently.
Our goal is to give you a reliable, safe system that meets your needs — whether that’s weekend boondocking or full-time vanlife.
Upgrading your Ecotrek battery system is one of the smartest improvements you can make to your Class B RV. With Edge Vanworks, you’ll get a system that performs better, lasts longer, and gives you the peace of mind to roam farther — without sacrificing safety or factory features.
We can have the install done in one day, but usually schedule two. We do a lot of work modifying KS2 boxes before hand.
If your RV has solar you may qualify for up to a 30% tax credit (Residential Clean Energy Act / RCEA) on the work we complete. From installing more energy efficient appliances, or adding solar panels, or repairing/upgrading the electrical system the tax credit has a wide variety of applications.
Let’s make your RV adventures more powerful, more comfortable, and more reliable. Whether you’re dealing with battery failure or just want better performance, we’ve got the solution.
