14.8V 50AH Marine electronic\Shuttle Battery [NMC]

Millertech 14.8V 50Ah NMC Battery 
The Millertech 14.8V 50Ah Lithium-Ion Battery is a high-performance power solution engineered to deliver extended, uninterrupted runtime for demanding
electronics and marine applications. Built for users who depend on consistent output—whether powering advanced sonar systems, multiple graphs, or other
high-draw equipment—this battery ensures your gear stays on longer, so you can focus on the mission, not managing power.
With 740 watt-hours of energy storage, the 50Ah model provides exceptional capacity in a compact, portable form factor—ideal for full-day use or multi-day
trips where access to shore power is limited. Whether you’re running forwardfacing sonar, powering multiple displays, or supporting auxiliary devices
onboard, the Millertech battery delivers steady, high-output performance with reliable voltage stability to help prevent dropouts, lag, or performance losses
under load.
For added control and visibility, the battery includes integrated Bluetooth connectivity, allowing you to pair directly with the Millertech App for real-time
monitoring. From your phone, you can track key battery metrics such as state of charge, voltage, current draw, and temperature, giving you confidence in
both runtime and overall system health—whether you’re actively using your gear or checking status between runs.
Key Highlights:
• Massive 50Ah (740Wh) capacity supports full day+ operation for demanding electronics
• Optimized 14.8V output for stable performance under continuous load
• Bluetooth-enabled monitoring through the Millertech App
• Track battery status, voltage, current draw, and temperature from your smartphone
• Reliable NMC chemistry for strong energy density, lightweight portability, and consistent output
Whether you’re running high-demand sonar setups, mobile equipment, or offgrid electronics, the Millertech 14.8V 50Ah NMC battery delivers the
endurance, stability, and smart monitoring tools you need to stay powered longer in the environments that matter most.
