The lighter, streamlined airframe uses a smaller 4200mAh LiHV battery — a different chemistry, different connector type, and different form factor from the original FD1 battery.

This is not a feature advantage — it is a necessity. The original FD1's integrated camera gimbal assembly and associated electronics add meaningful weight to the airframe, which demands a higher-energy battery to deliver acceptable flight times for fishing missions. The larger 6500mAh pack compensates for the heavier aircraft, providing sufficient flight time for practical bait deployments and ocean fishing missions despite the additional hardware weight.\u003c\/p\u003e\n\n\u003cp\u003eThe consequence is that the original FD1 carries less available payload capacity than the camera-free FD1+ and FD3 models, since a portion of the drone's total lift capability is used by its own heavier airframe. Keep this in mind when planning payload weights for bait, sinkers, and trace setups.\u003c\/p\u003e\n\n\u003ch2\u003eReal-World Flight Times for the Original Fisherman FD1\u003c\/h2\u003e\n\n\u003cp\u003eEstimated flight times for the original FD1 in Australian coastal fishing conditions with the 6500mAh battery installed:\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNo fishing payload, camera operating, calm conditions:\u003c\/strong\u003e Estimated 15–20 minutes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLight fishing payload (under 500g, including bait release and small rig), calm:\u003c\/strong\u003e Estimated 12–18 minutes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMedium payload (500g–1kg), light coastal breeze:\u003c\/strong\u003e Estimated 10–15 minutes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eAs with all drone fishing operations: return to shore well before the low-voltage warning activates. The FD1's automatic return-to-home function requires sufficient battery reserve to navigate back against typical coastal winds — the return leg into a sea breeze uses noticeably more power than the outbound run.
