24V Lithium Upgrade

In the world of high-performance marine and off-grid power, 24-volt systems are becoming the preferred standard for efficiency. By doubling the voltage of a traditional 12V setup, you can halve the current (amps) required to do the same work.

Why switch to a single 24V lithium battery?

While many users historically wired two 12V batteries in a series, modern 24V LiFePO4 batteries from Lithium Pros allow you to replace heavy, complex multi-battery banks with a single, lightweight unit. This transition simplifies your wiring, reduces points of failure, and sheds significant weight from your boat or rig.

Upgrading to a dedicated 24V lithium solution offers several technical advantages for both performance and system health:

Title

Massive weight reduction

Replacing two Group 31 AGM batteries (approx. 140 lbs total) with a single L2467-24 saves over 100 lbs. This improves boat speed, reduces draft, and increases fuel efficiency.

Reduced wiring complexity

A single 24V battery eliminates the need for series jumper cables. This reduces resistance and removes the risk of "unbalanced" charging that often occurs when wiring two 12V batteries together.

Constant power delivery

Lithium Pros 24V batteries maintain a steady 25.6V output until they are nearly empty. This ensures your equipment operates at peak efficiency without the "power fade" common in lead-acid systems.
Title

Three series, matched to your electrical demands

Lithium Pros designs distinct battery series to match specific electrical demands. Choosing the right series ensures you get the exact performance you need without paying for features you don't use.

Where 24V fits

Popular 24-Volt Applications

24-volt power is the "sweet spot" for several high-demand outdoor and marine industries:

High-thrust trolling motors

Most 70lb to 80lb thrust trolling motors are engineered for 24V power. A single 24V Lithium Pros battery provides consistent thrust all day long, even in heavy wind or current, ensuring your motor never loses its "punch" when you need it most.

Title

Advanced marine electronics & NMEA networks

For boats with massive electronics suites, 24V systems offer cleaner power with less electromagnetic interference. The N32105-24 integrates directly into your NMEA 2000 network, allowing you to monitor your battery health directly on your chartplotter.

Title

Efficient RV & overland house banks

24V systems are ideal for high-power camper builds. They allow for the use of thinner, lighter gauge wiring and make high-wattage power inverters run more efficiently, drawing fewer amps to power your microwave, AC unit, or induction cooktop.
