What this video covers
A LiFePO4 48V 100Ah battery from LiTime, provided for testing, powers an electric dinghy outboard at Madisonville, Louisiana.0:36 The tutorial walks through battery chemistry progression — car starter batteries, lead-acid deep-cycle, and finally lithium iron phosphate — explaining why lead-acid deep-cycle batteries must be discharged only to 50% to preserve their 500–1,000 cycle lifespan, while LiFePO4 can discharge to zero and delivers 3,000–5,000 cycles, translating to 10–15 years of daily use.7:19 The LiTime 48V 100Ah unit stores 5,120 watt-hours; at 500W draw (3–4 knots), runtime is 10 hours and range is 30–40 nautical miles.10:12 At 6 knots the draw rises to 2,000W, cutting range to roughly 2.5 hours — enough to push through 3–4 knot current encountered at Shroud Key.16:39 The battery's on/off switch eliminates the spark hazard when connecting 48V leads.14:35 Recharge takes 10 hours via AC charger or solar, so monitoring state of charge before departure is essential.11:56 The LiTime unit includes parallel-connection ports, an optional LCD state-of-charge display, and low-temperature charge cutoff (resumes at 5°C).9:30
