Built to meet the MAX's high-current motor demands, this battery delivers sustained power output under full payload loads without the voltage sag that compromises flight time and return-to-home safety with undersized or lower-quality third-party cells.\u003c\/p\u003e\n\n\u003cp\u003eIf you're targeting XOS snapper and kingfish from South Australian offshore beaches, running heavy ganged rigs through the surf for large pelagics, or deploying big live baits onto remote Western Australian reef structures, the Fisherman MAX and its genuine 4500mAh battery give you the payload capacity, flight endurance, and reliability to do it consistently and safely.\u003c\/p\u003e\n\n\u003ch2\u003eWhy the Fisherman MAX Needs a Larger, Heavier Battery\u003c\/h2\u003e\n\n\u003cp\u003eThe Fisherman MAX (FD2) is SwellPro's most powerful purpose-built fishing drone, capable of carrying greater payload weights than any other model in the Fisherman range. Its larger, higher-thrust motors draw significantly more current than the FD3 or FD1+ under equivalent flight conditions — and considerably more still when carrying maximum payload into a strong headwind at range offshore.\u003c\/p\u003e\n\n\u003cp\u003eThe 4500mAh 6S LiPo battery is sized to meet this sustained demand. At \u003cstrong\u003e1,255g\u003c\/strong\u003e, it is significantly heavier than the FD3\/FD1+ battery (716g) — and at \u003cstrong\u003e219 × 119 × 65mm\u003c\/strong\u003e, substantially larger in every dimension compared to the FD3\/FD1+ pack (153.6 × 82.4 × 48.3mm). The MAX's airframe and battery bay are designed around this larger pack — the drone's payload capacity figures are calculated with this battery installed as part of the total all-up weight.\u003c\/p\u003e\n\n\u003ch2\u003e6S LiPo Chemistry — Critical Differences From FD3\/FD1+ Batteries\u003c\/h2\u003e\n\n\u003cp\u003eThe Fisherman MAX uses \u003cstrong\u003e6S LiPo (Lithium Polymer)\u003c\/strong\u003e chemistry — not LiHV.

For safety and long-term cell health, consider using the charger's maximum 8A only when you need the fastest possible turnaround — for overnight or non-urgent top-up charges, a lower charge rate extends cell longevity over the battery's service life.\u003c\/p\u003e\n\n\u003ch2\u003eReal-World Flight Times With Heavy Payloads\u003c\/h2\u003e\n\n\u003cp\u003eThe Fisherman MAX is designed for heavy-payload performance, and the 4500mAh battery is sized to match that workload.

Actual flight time varies significantly with payload weight, wind speed, ambient temperature, battery age, and flight altitude. Always initiate return-to-home with at least 20% battery remaining — a heavy-payload RTH into a headwind demands substantially more current than a light outbound run, and the consequences of a forced water landing at range offshore are severe.\u003c\/p\u003e\n\n\u003ch2\u003eMulti-Battery Rotation for Extended MAX Sessions\u003c\/h2\u003e\n\n\u003cp\u003eThe MAX's 80-minute charge cycle at 8A makes a 2–3 battery rotation highly practical for extended beach sessions.
