16V 70AH Lithium Battery

Model #: CX1670 SKU: CX-16V-70AH-PRO

Product Details

The CHARGEX® 16V 70Ah LiFePO4 Bluetooth Lithium Battery is a high-performance dedicated power source engineered specifically for fish finders, marine sonar, radar, and other sensitive marine electronics. Delivering stable 16V output and 1120Wh of usable energy, this battery provides cleaner power with significantly reduced interference compared to standard 12V batteries.

Designed for serious anglers, the 16V architecture maintains higher voltage longer, resulting in up to 50% longer runtime, sharper sonar imaging, brighter displays, and more accurate fish detection on Hummingbird, Lowrance, Garmin, Raymarine, and similar systems. The built-in Bluetooth 5.0 allows real-time monitoring via the ChargeX app.
