Comparision of Electric Paddle board Fin Motors
Updated: Sep 6
The Spec Breakdown: Power, Weight, and Price of Electric Paddle Board Fin Motors
To properly compare electric Paddle board fin motors, we need to balance motor wattage, total battery capacity, deck weight, and overall value.
To find the true energy capacity, we use the formula:
Wh=Voltage (V)×Amp-hours (Ah)
Feature | ParadisePad Silver Efin | Ledonne EP18LT |
Price | $550 | $499 |
Motor Power | 450 W | 160 W |
Battery Specs | 36V, 13Ah | 25.6V, 10Ah (approx.) |
Total Energy | 468 Wh | ~256 Wh |
Battery Weight | 7.6 lbs | 8.7 lbs (3.95 kg) |
Top Speed | 5.5–7 mph | ~4.5–5 mph (8 km/h) |
Energy Density (Wh / lb) | 61.6 Wh/lb | 29.4 Wh/lb |
Power-to-Weight (W / lb) | 59.2 W/lb | 18.4 W/lb |
Value ($ / Wh) | $1.18 / Wh | $1.95 / Wh |
Direct Comparison Analysis
Energy Capacity & Deck Weight: For a $51 difference, the ParadisePad Silver Efin provides nearly double the total power capacity (468 Wh vs. 256 Wh) while shedding 1.1 lbs off your board's deck. The Ledonne's battery pack results in an energy density of 29.4 Wh/lb compared to the Silver Efin's 61.6 Wh/lb.
Thrust & Speed Performance: The ParadisePad delivers nearly triple the motor wattage (450W vs. 160W), yielding a 59.2 W/lb power-to-weight ratio compared to the Ledonne's 18.4 W/lb. This translates to higher top speeds and stronger resistance when paddling against currents and headwinds.
True Economic Value: The ParadisePad Silver Efin operates at $1.18 per Watt-hour stored compared to $1.95 per Watt-hour on the Ledonne EP18LT, delivering a better return on investment across every metric.
Verdict: With only $51 separating these two options, the ParadisePad Silver Efin completely outclasses the Ledonne EP18LT—offering nearly triple the propulsion thrust, double the energy runtime, faster top speeds, and lower overall deck weight.
Deep Dive: Blog Takeaway & Recommendation Guide

1. ParadisePad Silver Efin (450W / 13Ah) — $550
This is the undisputed powerhouse of the lineup. If your readers are adventure tourers, paddleboard fishers carrying heavy gear, or anyone dealing with aggressive coastal tides, this is the top-tier recommendation after doing our comparision of electric paddle board fin and motors. Named the "Best Bang For The Buck by Best Review"
The Power Advantage: The 450W motor delivers significantly higher torque, allowing you to hit speeds of 5.5 to 7 mph and push through strong headwinds where weaker motors bog down.
The Range King: At 468 Wh, it has nearly double the battery capacity of the Ledonne. You can expect up to 1.5–2 hours at wide-open throttle, or up to 10 hours in eco-mode.
The Weight Dynamic: Packing this much massive capacity into just 7.6 lbs offers incredible energy density for the amount of power it pushes.

2. Ledonne EP18LT (160W / 25.6V) — $498.00
The Ledonne operates on an entirely different tier. It shouldn't be viewed as a "jet engine" for your board, but rather as an e-bike style pedal assist.
Gentle Assistance: At 160W, it's designed to take the bite out of paddling fatigue rather than doing all the heavy lifting. It's excellent for seniors, beginners, or calm lake cruising.
The Weight Surprise: At 8.7 lbs, the Ledonne battery is actually the heaviest of the three despite having the lowest motor power. This means you carry more weight on deck for less overall speed.
The Pricing Problem: At $499, it sits only $50 cheaper than the ParadisePad Efin, despite offering less than half the motor wattage and a heavier battery footprint.

The Ultimate Dealbreaker: Company Location & Spare Parts
When choosing a motorized fin, where the company is located and how they handle support is just as important as the specs.
ParadisePad: USA Family-Based Company
Who they are: ParadisePad is a family-owned and operated watersports company based right here in the USA since 2015
Support & Spare Parts: Because they are domestic and deeply rooted in the boating community, they actively stock spare parts. If you lose a remote, damage a prop, or need a replacement component down the line, you can actually get a hold of them to fix your investment rather than throwing it away.
Ledonne: China-Based Company
Who they are: Ledonne is a company based in China. While they sell globally through third-party platforms, their infrastructure is entirely overseas.
The Risk Factor: Ledonne does not mention anything about getting spare parts. If a proprietary component breaks outside of a basic return window, your $499 investment risks becoming a paperweight because tracking down replacement parts from an overseas generic manufacturer is notoriously difficult.
Blog Takeaway & Recommendation Guide
Best Overall & Long Range: ParadisePad Silver Efin (450W/13ah - $550) — Unmatched power, a top speed up to 7 mph, and robust battery life for serious paddlers who refuse to get stranded by strong tides.
