24V vs 36V Trolling Motors: Which Voltage System Is Right for You?

24V vs 36V Trolling Motors: Which Voltage System Is Right for You?

One of the most common questions when buying a trolling motor is: do I need 24V or 36V? The answer depends on your boat size, fishing conditions, and how long you need to run. This guide breaks down everything you need to know to make the right call.

Quick Comparison Table

Factor 24V System 36V System
Batteries Required 2 x 12V 3 x 12V (or 1 x 36V lithium)
Max Thrust Available Up to ~80 lb Up to 115 lb+
Run Time Good Excellent
Best For Boats under 20', light conditions Boats 20'+, wind, current, heavy use
Battery Cost Lower upfront Higher upfront (lower per-hour with lithium)
Motor Efficiency Good Better — less heat, more torque
Weight Less (2 batteries) More (3 lead-acid) or less (1 lithium 36V)

When to Choose 24V

A 24V system is the right choice when:

  • Your boat is under 18–20 feet
  • You fish protected lakes and rivers with minimal wind and current
  • You want a simpler, lighter battery setup (2 x 12V)
  • Your motor is rated for 24V (many Garmin Force Kraken and Power-Pole MOVE models run 24V/36V)
  • Budget is a primary concern — two batteries cost less than three

When to Choose 36V

A 36V system is the right choice when:

  • Your boat is 20 feet or longer, or heavy (pontoons, bay boats, bass boats)
  • You fish open water, reservoirs, or coastal areas with wind and current
  • You need maximum thrust (100–115 lb) for all-day holding power
  • You want longer run times without recharging
  • You're upgrading to a lithium battery — a single 36V lithium pack is lighter than three lead-acid batteries

Motors That Run Both 24V and 36V

Several motors in our catalog offer 24V/36V flexibility, letting you start with two batteries and add a third later:

36V-Only Motors

Some motors are 36V-only, delivering maximum power with no compromise:

The Lithium Advantage at 36V

If you're going 36V, seriously consider a lithium battery. A single 36V lithium pack replaces three heavy 12V lead-acid batteries, saving 60–80 lb of weight while delivering more usable capacity and faster charging.

GPS Anchoring: Does Voltage Affect Performance?

Yes — voltage directly impacts how well your GPS anchoring system holds position in wind and current. A 36V motor has more reserve thrust to make rapid corrections, which is especially noticeable with systems like Garmin Anchor Lock and Minn Kota Spot-Lock in heavy current.
