DIY Kayak Efficiency Test: How I saved 70% battery dropping from 6km/h to 5km/h (19A vs 5.85A)

I wanted to map the exact power draw of my custom electric setup (Caperlan/Itiwit 100) pushing through a 3.3 m/s wind.

As you can see in the telemetry on the right:

• Pushing max throttle (6.0 km/h) draws 19.0 Amps.
• Dropping just 1 km/h to cruising speed (5.0 km/h) drops the draw to 5.85 Amps.
