THE PROBLEM
One bank drains while the other sits full. You're constantly checking voltages and manually switching between banks. Your expensive batteries wear out unevenly.
Multiple relays, shunts, switches, and bus bars. A mess of cables that's impossible to troubleshoot. One loose connection and your whole system goes down.
You have no idea what's actually happening in your system. Is the battery at 50% or 20%? Is something draining power overnight? You only find out when it's too late.
A proper dual-bank setup costs $1,300+ in components alone. Then you need an electrician to install it. And when something fails, good luck finding the problem.

Built to withstand the harshest environments, this device features a rugged aluminum housing, corrosion-resistant terminals, and a vibration-dampened design. Engineered for reliability, it delivers consistent performance in operating temperatures ranging from -20°C to +60°C.
OLD WAY vs KALIONTM WAY
The Old Way
Multiple relays, shunts, bus bars, and manual switches. Excessive wiring, complexity, and high cost.
The KalionTM Way
One device, one intelligent solution. Install in 30 minutes. Drastically reduced failure points and simplified power management.

FAQs
75A continuous per bank with 150A surge capacity for motor starts and high-inrush loads. That's enough for inverters up to 3.6kW on a 48V system.
KALION DUOTM automatically detects and supports 12V, 24V, and 48V systems (10-60V DC range). No manual configuration needed — just connect and go.
KALION DUOTM is IP54 rated — protected against dust and water splashes. Perfect for engine rooms, under-seat installations, and outdoor enclosures. Not designed for direct water submersion.
Just 6 power connections and 30-60 minutes. No electrician required. Connect your two battery banks, connect your load output, and power on. The touchscreen guides you through setup.
Early Bird backers are estimated to receive their KALION DUOTM units by July 2026. We'll keep you updated throughout production with regular backer updates.
Basic isolators (€50-150) only do one thing — connect/disconnect based on voltage. They can't tell you state of charge, they don't track current flow, they have no app, and they don't optimize for solar or multiple charging sources and voltages.
KALION DUOTM replaces your isolator AND your battery monitor AND your display AND your shunts — all in one intelligent system with a 4inch color touchscreen WIFI and Bluetooth connectivity and a phone app.
We're launching in two stages to bring KALION DUOTM to life:
Stage 1 — Indiegogo (Now): We're raising $15,000 to fund our production-ready prototype.
This is where you get the absolute best pricing — up to 50% off. Limited to 200 backers.
Stage 2 — Kickstarter (2026): Once the prototype is validated, we'll launch full production on Kickstarter. Early bird pricing still available but slightly higher.
Both platforms offer backer protection. Join our email list to be notified first
