Smart Sleep Mode further enhances both safety and battery life.
Robust and flexible installation
With an IP65 rating, the battery is resistant to dust and water splashes, making it ideal for boats, RVs, and stationary off-grid setups alike.
Lightweight and compact dimensions make installation easy — even under a seat.
Full control with Bluetooth and app
