M2 OLED DC State-of-Charge Monitor — BSS-1830
Know exactly how much battery capacity you have left before it matters. The M2 OLED DC State-of-Charge Monitor gives you a real-time, at-a-glance readout of your battery bank's remaining charge — displayed on a crisp, high-contrast OLED screen that's easy to read in direct sunlight or low-light conditions below deck.
Key Specifications
- Display: OLED — high contrast, wide viewing angle
- Function: DC State-of-Charge (battery percentage remaining)
- Mount: Panel-mount
- Part No.: BSS-1830
- Weight: 200 g (approx.)
Best Use Cases
- House battery bank monitoring on sailboats and cruising powerboats
- Anchor-out or liveaboard setups where knowing remaining capacity prevents unexpected discharge
- Any 12V or 24V DC system where a clear, reliable state-of-charge readout is needed at the helm or nav station
Parts Desk Insights
The M2 OLED is the go-to recommendation when a customer wants a dedicated state-of-charge display rather than a full multi-function meter. The OLED panel reads cleanly in the cockpit without backlighting adjustments. If the customer also needs AC shore power monitoring, pair it with the M2 OLED AC Multimeter. For a broader DC monitoring solution that includes voltage and current alongside state-of-charge, see the M2 OLED Digital Meter, DC Monitor.
