FAQ

Frequently Asked Questions

Everything you need to know before you order

When will KALION K5™ ship?

Target launch: Q2 2026. Pre-orders open soon. Sign up to be notified 48 hours before public launch.

Can I really use both touch AND buttons?

Yes! This is a first in battery monitors. Use the capacitive touch screen when convenient, then switch to physical buttons if your hands are wet, dirty, or gloved. Both input methods work simultaneously.

What makes dual-bank monitoring important?

Most systems have a house bank and a starter bank. Traditional monitors force you to choose one. K5™ monitors both simultaneously with independent state-of-charge calculations.

How is KALION K5™ different from Victron BMV-712?

K5™ adds: dual-bank native, 3.5" touchscreen, WiFi, RGB status LEDs, haptic feedback, MicroSD logging, and future VE. Direct integration. Victron is a proven work horse but lacks modern features.

Why should I trust a new brand over Victron or Simarine?

Fair question. We're using proven components and open-source firmware. We'll offer a 2-year warranty and lifetime software updates. Plus, you're getting 8 features no competitor offers at $100-300 less.

Can K5™ integrate with my existing Victron system?

Hardware is ready! VE.Direct functionality will be enabled in v1.5 firmware (Q2 2026). You'll be able to display MPPT and charger data directly on your K5™.

What's included in the box?

KALION K5™ monitor, panel mount gasket, mounting hardware (4× M4 screws), panel cut out template, temperature sensor cable (JST-XH), quick start guide.

Do I need a separate shunt?

No! K5™ has integrated screw terminals. Connect your battery cables directly to the monitor. Much cleaner installation than external shunt boxes.

What warranty and support do you offer?

2-year limited warranty covering defects. Lifetime firmware updates via WiFi OTA. Email support with 24-48 hour response time. Active community forum for tips and trouble shooting.

Can I monitor 3 or 4 battery banks?

K5™ natively monitors 2 banks. For 3+ banks, you can use multiple K5™ units or wait for our future KALION K10™ model (4-bank capable, planned Q3 2026).
