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.
