Start with the battery problem on your boat.

Most kayak power problems are not glamorous. You have one battery for the motor, another for electronics, a charger that only fits one thing, and cables running wherever they can fit.

Flux is a bridge between batteries and equipment that use different voltages. One model can use a 12V battery to charge a 24V or 36V trolling motor battery. Another can use a higher-voltage battery to run 12V equipment.

Why Flux Exists

The problem is not voltage. It is clutter, weight, and uncertainty.

A modern fishing kayak can have a trolling motor, fish finder, phone, lights, pumps, cameras, and maybe solar or a second battery. The hard part is not buying another component. It is getting the whole setup to make sense.

Flux Charge and Flux HV use available 12V capacity to charge a matched 24V or 36V trolling motor battery. A solar-backed 12V battery can also become part of an auxiliary charging setup.

Flux Drive 12 goes the other direction. It uses a 24V, 36V, or 48V lithium battery to provide regulated 12V power for a matched trolling motor and onboard accessories. Each build still has to match the battery, BMS, wiring, connectors, fuse sizing, heat, and use case.
